About the Library
History of the Library
The Library started when NFE was a company of just 3 people to make sharing information efficient and easy. We knew that future NFE team-members wouldn’t be able to see emails about process changes that were being sent before they joined and that most of the people who would eventually join NFE likely hadn’t even heard of us yet. This Library was our way of ensuring that all of our company information was accessible to everyone regardless of when they became part of the team.
Advantages
At NFE our Library is extensive and keeping it relevant is an important part of everyone’s job. It is a vital part of who we are and how we communicate. We established these processes because we saw these benefits:
- Reading is much faster than listening.
- Reading is async, you don’t have to interrupt someone or wait for them to become available.
- Talent Acquisition is easier if people can see what we stand for and how we operate.
- Retention is better if people know what they are getting into before they join.
- On-boarding is easier if you can find all relevant information spelled out.
- Teamwork is easier if you can read how other parts of the company work.
- Discussing changes is easier if you can read what the current process is.
- Communicating change is easier if you can just point to the page history.
- Everyone can contribute to it by directly editing a page.
One common concern newcomers to the Library express is that the strict documentation makes the company more rigid. In fact, writing down our current process in the handbook has the effect of empowering contributors to propose change. As a result, this Library is far from rigid. You only need to look at the Library home page to see the evidence. Every attempt is made to document guidelines and processes in the Library. However, it is not possible to document every possible situation or scenario that could potentially occur. Just because something is not yet in the Library does not mean that it is allowed. Aaron Tushabe is the primary custodian of the Library, please talk to him in the #general channel on Matrix if you're unsure about something concerning this Library.
Library Interpretation
The Library is subject to interpretation. We do our best to be as clear as possible to minimize confusion and/or misinterpretation. We also recognize that we have a global audience and that may bring different interpretations. If you have any questions or need further clarification please check with the content owner of any given page. When in doubt please reach out and ask.
Remember that everything is in draft at NFE and subject to change, this includes our Library.
We rarely mark any content or proposals as drafts. Everything is always in draft and subject to change. When everything is in draft, contributions from team members as well as the wider community are welcomed. By having everything in draft and assuming others have low context, confusion can be reduced as people have shared access to information.

NFE <> EnAccess Checkin
Attendees
- Aaron Tushabe - NFE
- Vivien - EnAccess
- Daniel - EnAccess
Meeting link: https://meet.google.com/rpg-vpmw-zzh
Agenda
- Introductions
- Expectations for NFE using EnAccess provided MPM instance for Sezibwa Rentals Pilot
- Daniel: For transparency: We haven't yet had the time to fully clarify and conceptionalise our ToS for MPM, w.r.t SLA/SLO/Uptime promises/Data security, but also pricing to cover the infrastructure costs etc... As a result we currently provide the MPM cloud service this "as-is".
- Aaron: This is understood and when we are successful with the pilot, we'd like to collaborate on the posibility of agreeing on some Terms of Service or setting up NFE's self hosted instance. I think the community needs an instance to quickly evaluate MPM cheaply and quickly so I'd prefer we collaborate on improving the cloud.mpm.io experience more production ready for new joiners.
- Support with Regular Community Calls on MPM/EnAccess projects/materials
- Let's talk about how I can help, I have ideas but I some questions first
- Who do you recommend I pair with on this one. I am of the view that initiatives are more resilient if we have more than one human co-owning it so I'd like to have someone I pair with to get this going. I can reach out to Thulie add see if she's up for it
- Anything that has been tried in the past that I should consider before proposing something?
- Let's talk about how I can help, I have ideas but I some questions first
- NFE overview
- I have a pitch deck I keep refining and our bylaws share more about our ownership model

Quick summary
During this meeting, Aaron, Hillary discussed, the current meter-logging system, data buffering and aggregation approach, deployment pipeline, backup and metadata storage, and commissioning/precommissioning of meters.
Action items for Aaron
- Wrap up gateway deployment repo and onboard Hillary so he can use it going forward
- NFE Web app integration with real (CSV) data via nextcloud once Hillary has populated sample meter data; coordinate timing for verification.
Action items for Hillary
- Implement and enable the 15-minute buffering and averaging approach (already in place) and ensure exported log entries represent averages for each 15-minute window; document the buffering logic.
- Adjust the backup/upload timer to start with hourly uploads and monitor cost/performance; report recommended cadence after initial test period.
- Deploy the meter services to the other production Pi and validate that the metadata folder is populated with meter folders (start tonight where possible).
- Add a commissioning/precommissioning script that converts meters from the Chinese protocol to Modbus, assigns temporary address 1 for precommissioning, then writes the production address and serial number; document the commissioning procedure and constraints (e.g., stopping services may lock serial port). Onboard Dansturn to execute on this
- Share the correct metadata/metadata folder link and confirm access is granted to Aaron; reorganize folder structure as discussed (metadata -> customer -> meter folders).
- Test image building and deployment flow (VM build -> push to main -> CI build image -> manual deploy) and document the exact deployment commands.
- Test upgrading the client version in a staging environment and report any compatibility/security concerns before upgrading production.
Notes: Hillary already demonstrated the buffering (10s sampling, 15-min average) and the backup/upload service; team agreed to start with hourly uploads and scale as needed. Commissioning constraints and Modbus address conflicts were discussed; precommissioning workflow will be created to avoid on-site conflicts.

Tech Huddle - Behind the Meter Connection for each customer
How each customer is metered and controlled behind the bulk connection, in the Street-EMS design. Companion to the authoritative page "NFE metering strategy + Glen Street-EMS".
The question
Behind NFE's single bulk utility connection sit many single-phase tenants. "Behind the meter connection for each customer" is how we meter, bill, and control each of them individually without a separate utility meter per tenant.
Today (CHINT + Pi)
Each tenant has a CHINT DDSU666 postpaid meter on a DIN rail. A Raspberry Pi gateway polls them over Modbus RTU / RS485 and feeds OpenEMS. Billing is postpaid off the meter reads. Control (disconnect) is manual at the breaker.
Street-EMS (next generation)
One cabinet meters and controls up to 9 tenants (3 per phase) with no per-tenant meter:
- Metering: 3 stacked CircuitSetup 6-channel CT boards on the EMS controller give 18 CT channels: one per tenant (9), one per phase mains (3), and 6 spare. Each tenant's usage is a dedicated CT (no separate meter box).
- Control: each tenant runs through a contactor (K1..K9) whose coil is driven by an opto-isolated SSR from the EMS. That is the per-customer remote connect/disconnect used for prepaid enforcement and protection trips.
- Safety: three Ivy residual-current monitors (one per phase) give continuous leakage and neutral-imbalance insight across all tenants on that phase.
- Per-tenant policy: the EMS holds a JSON "mode" per tenant (prepaid expiry, over V/I/kW/kWh, over-generation/storage), and can warn (RGBW LED or e-paper, flash cadence) before a graceful cutoff, optionally leaving a small post-sunset lighting allowance from battery.
Ratified: 1P (do not switch neutral except for EV), 80A rating for future EV. See the authoritative page for the full line diagram, firmware vision, and workshop context.

Overview
The call focused on whether MPM should evolve to better support grid-connected mini-grids, especially postpaid billing, meter integrations, and monitoring of batteries/solar assets. The team agreed the current direction is promising for the Nigerian mini-grid use case, but emphasized that new capabilities should be integrated carefully so the platform remains technically coherent and maintainable.
Why the conversation happened
Aaron raised a strategic question: whether the current MPM product is being pushed beyond its original design by supporting grid-connected mini-grids, or whether a new system should be built instead. Vivien and Daniel clarified that MPM was historically built as a mini-grid CRM and later adapted by solar home system companies by the newest work in Mozambique. However, new conversations with REI in Nigeria is increasingly steering it toward mini-grid needs again.
Product positioning and strategic direction
Vivien explained that MPM’s roots are in mini-grid operations and CRM workflows, not solar home systems, even though solar home system companies adopted it over time. He noted that recent demand from Mozambique and a larger contract in Nigeria are driving more mini-grid-specific work, including OEM integrations, dashboard hardening, and other adaptations.
The team also discussed the upcoming PayGo Ops community edition, which may better serve some solar home system users. Vivien’s view was that this does not undermine MPM’s mini-grid identity; rather, it highlights that MPM should keep focusing on the mini-grid segment while remaining open to adjacent use cases where appropriate.
Postpaid vs. prepaid metering
A major topic was Aaron’s observation that the pilot became easier when the team moved away from a proprietary prepaid meter setup and adopted postpaid billing. Aaron had originally feared that MPM might be too biased toward prepaid workflows, and wondered whether postpaid mini-grid support would require an entirely new system.
Daniel responded that prepaid metering is easier to support technically because the abstraction is straightforward: a customer pays, a tariff applies, and energy is delivered. Postpaid introduces more complexity because it requires tracking usage over a billing period, calculating debt/amount owed, and handling billing logic in a less linear way. Daniel said MPM already has some related concepts, but postpaid still requires careful design so the abstractions remain coherent.
Metering and data acquisition lessons from the pilot
Aaron described the operational problems they faced with a Chinese vendor, Kalin: the meters claimed to support both prepaid and postpaid, but the vendor did not expose meter data directly. Instead, the team had to use proprietary middleware APIs hosted by the vendor, which caused reliability issues, token-lockout problems, slow support response times, and pressure to place larger orders before the pilot was stable.
To solve this, the team switched in March 2026 to locally sourced meters that are postpaid-only and expose data via RS-45/Modbus into a Raspberry Pi, which is then connected to the internet through a modem. This setup gave them direct access to meter data, reduced dependency on the vendor, and eliminated the operational risk of needing tokens from overseas just to unlock a customer meter.
Aaron also noted that the meters are physically clustered in a single PDU, which makes wired connectivity practical in this pilot. Vivien pointed out that this works for dense apartment-complex style deployments, but would not translate well to rural, dispersed mini-grids where wireless communication is usually more appropriate.
Open-source monitoring and OpenEMS integration
Aaron said the pilot team had already contributed a plugin to OpenEMS so that usage data from the new meters can be read in real time. He suggested a future model where OpenEMS handles monitoring of meters, batteries, and solar assets, while MPM handles business functions such as billing, invoicing, and customer communication.
Daniel and Vivien were receptive to this division of labor. Vivien emphasized that the goal should be integration rather than rebuilding existing open-source tools. He referenced the existing Prospect integration as a model: ideally, MPM should connect with external monitoring systems in a way that lets users move seamlessly between tools rather than duplicating functionality.
Battery and solar support
Aaron asked whether MPM was originally intended to handle batteries and solar generation data as part of mini-grid operations. Daniel clarified that this was not part of the original core focus. MPM’s main scope has been customer transaction management and business workflows, not system monitoring.
That said, Daniel acknowledged that there is a gray area where battery or solar data affects billing, and therefore may need to be integrated into MPM workflows. He stressed that system monitoring should not simply be bolted on as a disconnected feature. Instead, the team should think carefully about where such data belongs, how it is modeled, and how it can be integrated without making the product overly complicated.
Billing, customer visibility, and invoicing features
Aaron demonstrated the pilot’s customer-facing web app, which lets customers see their usage, estimated bill, and end-of-month projection. The app refreshes automatically every six hours, with manual refresh available. This was intended to reduce uncertainty for customers and let them see charges before the monthly billing cycle closes.
He also showed the microgrid manager billing interface, where customer data is imported, billing cycles are created monthly, invoices are generated, and payment links are attached through a payment service. Aaron highlighted this as one of the strongest parts of the pilot and argued that MPM should gain similar invoicing capability, alongside an integrated payment-provider flow and an OpenEMS data source.
The group agreed that these were the most concrete candidate features to pursue. Aaron said his team could likely push the payment integration and invoicing work, while also helping define the OpenEMS plugin approach and continuing conversations with Nigerian partners.
Nigeria and regulatory relevance
Vivien stressed that Nigeria is especially relevant because it has an active mini-grid market, including grid-connected mini-grids, structured regulation, and tariff systems that resemble the use case Aaron is working on. Aaron agreed, noting that Uganda’s regulator is increasingly looking to Nigeria as an example for policy development, and that his team is preparing a paper to make the case for adopting elements of Nigeria’s regulatory framework.
The discussion made clear that Nigeria is both a strong market for the problem and a promising source of practical solutions. Vivien also suggested Aaron could observe some conversations EnAccess has with other community members who are focussing on Mini-grids.
Managing codebase complexity and simplification
Later in the call, Aaron asked whether there should be a roadmap for removing or disabling legacy features from MPM, since long-running applications tend to accumulate unused functionality. Daniel said the team had spent much of 2025 removing things, but had recently shifted toward adding new capabilities. He agreed that managing complexity is an ongoing concern.
Daniel distinguished between two kinds of simplification:
-
user-facing simplification, such as hiding advanced options by default or using more sensible defaults;
-
backend simplification, which is harder because core abstractions like “mini-grid” are deeply embedded in the codebase.
Obinna added that from his experience, the team usually receives feature requests rather than removal requests. He suggested that if the roadmap included clearer visibility into unused functionality, he could help identify features that no one appears to use and also warn when something that looks unused is actually used by someone else.
Key takeaways
-
MPM is still seen by the team as a mini-grid CRM, not just a solar home system platform.
-
Postpaid support is viable, but it needs deliberate abstraction design.
-
Direct meter integration and open data access are critical for reliable mini-grid operations.
-
OpenEMS is a strong candidate for handling monitoring, while MPM should focus on billing, customer/account management, and payment workflows.
-
The strongest near-term product opportunities are invoicing, payment-link generation, and an OpenEMS data-source integration.
-
The team should continue exploring simplification opportunities, but removal of legacy code or features needs a more explicit process and roadmap.

NFE Checkin - August 8th 2026
Date: 8 August 2026
Attendees: Aaron Tushabe, Dansturn Kimbowa, Hillary Arinda
Duration: ~2 hours 5 minutes
1. Nansana Pilot & Battery Backup
The Nansana battery backup system is now live and billing has proceeded without major issues. Initial operation indicates a significant reliability improvement, particularly during the daytime. During outages, the batteries have generally supported the site for approximately 1–1.5 hours under heavier evening loads, and substantially longer when customers reduce high-consumption appliances.
A useful behavior has also emerged organically: residents notify each other when the site has switched to battery and encourage reduced consumption. The team agreed this should eventually be automated so customers are notified when they switch to backup power. This would both help extend battery runtime and make the reliability value of the NFE service more visible to customers.
The telemetry stack is not yet sufficiently stable to accurately measure and report outage duration, battery behavior and reliability over time. The immediate priority is therefore to stabilize telemetry and establish a reliable baseline before experimenting extensively with battery operating strategies.
Battery Optimization
The current battery configuration primarily preserves stored energy for outages. The team discussed experimenting with time-of-use arbitrage, where batteries charge during cheaper off-peak periods and discharge during peak tariff periods while maintaining a minimum reserve for outages.
One possible configuration discussed was allowing discharge to approximately 50% during peak periods before reverting to grid supply. These experiments should only begin once telemetry is stable enough to compare their impact on both reliability and margins.
2. OpenEMS Migration & Q3 Technical Priorities
The Q3 development objective remains to consolidate both metering and battery monitoring onto OpenEMS, creating a common technology stack for future deployments. Once the OpenEMS metering integration and automated billing flow are stable, NFE should have a more commercially scalable sub-metering platform.
Progress has been made integrating the inverter, although discrepancies between available documentation and the installed inverter firmware have required experimentation. The target is to resolve the outstanding inverter integration issues during the coming week.
The team also discussed configuration management within OpenEMS. For Q3, the current configuration-file/Felix UI approach will continue rather than building a new management interface. Building a separate interface was considered outside the current Q3 scope.
Some technical questions remain around:
-
How OpenEMS writes configuration changes through to inverter registers.
-
Whether charging windows can be changed through the currently exposed registers.
-
How future automated optimization software would dynamically modify inverter settings.
-
Whether some historical meter data needs to be backfilled into the new stack.
Historical backfilling was considered secondary to getting current data flowing correctly into OpenEMS.
3. Billing, Service Charge & Economics
The team reviewed the economics of the Nansana site. It is still too early to determine whether battery installation has materially improved margins because:
-
there has not yet been a full operating month;
-
the initial battery charging introduced additional consumption;
-
electricity tariffs changed during the period; and
-
the NFE service charge was also adjusted.
The reliability improvement is already more apparent than the profitability impact.
The discussion highlighted the need for a more rigorous model for determining the appropriate monthly service charge. Future pricing should reflect both:
-
the value of improved reliability delivered to customers; and
-
NFE's actual operating and maintenance costs.
The existing service-charge adjustment was acknowledged as a reasonable pilot decision rather than a fully cost-derived commercial price.
4. Battery Funder / Data Sharing
The battery funder is aware that the backup system has been installed and has indicated willingness to potentially contribute an additional small amount toward installation costs. Aaron has a follow-up meeting scheduled for Monday to provide an update and review the roadmap.
The original arrangement requires NFE to share operational data. The team agreed there is no need to make historical data migration a blocker. Existing spreadsheet records can be shared for earlier periods, while newer telemetry can be exported from the current database/OpenEMS stack.
5. Analytics Layer / AI-native Operations
The current system collects telemetry into InfluxDB, but NFE does not yet have a defined analytics layer.
The team revisited the broader Microgrid OS architecture and discussed potentially avoiding a dashboard-heavy analytics approach. One promising direction is an LLM-powered operational analytics interface sitting over the telemetry data, potentially using MCP or a similar interface to allow users to ask questions such as:
-
Which outages lasted longer than three hours this week?
-
What is the site's reliability trend?
-
How has a particular battery configuration affected consumption or uptime?
The analytics architecture should be revisited as part of future/Q4 Microgrid OS planning.
6. Nairobi Workshop — Generation 3 Hardware
The Nairobi workshop is proceeding, with three sponsored participation slots currently available.
The team clarified that the objective should not simply be to attend or observe the workshop. The explicit goal is to leave Nairobi with a pathway toward Generation 3 of the NFE microgrid/sub-metering stack.
The generations were framed as:
Generation 1
-
Proprietary hardware.
-
Proprietary software.
-
Imported equipment.
-
Higher equipment and licensing costs.
Generation 2
-
Locally available but still proprietary meters/hardware.
-
Open-source software through OpenEMS.
-
Lower hardware cost and reduced software lock-in.
Generation 3
-
Open hardware that NFE can assemble locally.
-
Open-source firmware/software.
-
Components that can be repaired or replaced individually.
-
Greater control of the full stack.
-
Significantly lower per-customer hardware costs.
A preliminary BOQ discussed during the meeting suggested an equipment cost of roughly US$64 per customer for the workshop hardware configuration, although this still needs validation.
The team acknowledged that moving the workshop prototype into a production-grade NFE system will require additional engineering, testing, enclosure/assembly work and software integration.
7. UNBS Certification
A key open issue for Generation 3 hardware is regulatory approval.
Once NFE begins assembling its own metering hardware and using it for customer billing, UNBS certification/calibration requirements will become important. The team needs clarity on:
-
the applicable certification process;
-
costs;
-
testing/calibration requirements;
-
documentation required; and
-
whether certification applies to the complete assembled PDU, individual meters, or both.
This will determine whether the open-hardware approach remains economically attractive relative to using already-certified commercial meters.
8. Customer Pipeline
Chanjala / Three-phase Connection
The outstanding issue remains the three-phase supply/meter installation. UMEME appears ready to install once the required meter payment and outstanding site-side issues are addressed.
The team discussed proceeding with the meter installation while treating any problems with the customer's internal/network infrastructure separately.
Dansturn Home Installation
Dansturn would like NFE monitoring installed at his home so that he can better understand his electricity consumption.
This is also considered a useful test environment because it provides the engineering team with a site that is easier to access than Nansana. The same installation can help refine the product before installing for Edward and other individual customers.
Target discussed: Monday/Tuesday during the coming week, subject to technician availability.
9. Target Customer Strategy
The team revisited whether NFE should prioritize new construction or existing sites.
The conclusion was that existing developments with:
-
active electricity consumption;
-
meaningful numbers of customers; and
-
an immediate reliability problem
remain the more attractive near-term market.
New developments can still be considered where the developer bears the upfront metering/infrastructure cost, but NFE should avoid tying up its own capital for years waiting for occupancy and consumption to ramp up.
10. Conferences & Industry Engagement
Nairobi
NFE currently has three sponsored passes and expects to send the founders/team, subject to individual availability.
Kigali
The team is also exploring participation in a Kigali event. Aaron will investigate whether NFE can obtain passes and potentially participate as workshop facilitators or presenters.
The team agreed to resume a physical working session on Friday, with Nairobi preparation being one of the main priorities.
11. Fundraising & Corporate Readiness
NFE is awaiting outcomes from current grant opportunities and needs to identify additional fundraising avenues, particularly to support further deployment work at Pearl Marina and other sites.
The team also briefly discussed ensuring NFE's equity/shareholding documentation is properly organized ahead of future grant, investment or corporate due-diligence processes.

Participants: Aaron Tushabe, Dansturn Kimbowa, Hillary Arinda
1. Power Africa / Nairobi
NFE has received travel support for the upcoming Power Africa/IEEE-related activities in Nairobi. The current support appears to include reimbursement of Uganda–Nairobi bus transport up to US$150/person, accommodation, airport transfers and most meals. The main outstanding question is the approximately US$300 conference registration fee, which was the item NFE had originally hoped would be sponsored.
Aaron's attendance remains tentative because of possible travel restrictions, while Dansturn is expected to attend if possible. The team also discussed the possibility of participating in related activities in Rwanda later in October.
Decision: Continue preparing for Nairobi, but clarify whether registration fees can also be covered.
2. Financing NFE deployments
Aaron reported on his discussion with Stanbic's renewable-energy financing team.
Two financing structures were discussed:
-
Working-capital financing: requires collateral and is less suitable for NFE's current requirement.
-
Asset financing: appears substantially better aligned with NFE because the loan can specifically finance solar/battery equipment whose project cash flows repay the loan.
Indicative Stanbic terms are up to about 15% per annum, potentially lower for larger transactions, with financing periods potentially extending considerably longer for larger projects.
However, the bank may require:
-
audited financial statements;
-
evidence of project cash flows;
-
project/site due diligence;
-
appropriate property/site documentation;
-
a qualified/approved EPC or equipment supplier;
-
appropriate equipment warranties and maintenance arrangements.
This highlighted an important issue for NFE: procurement, installation and maintenance are currently somewhat separated. For bank-financed projects it may be advantageous to structure these more formally around an EPC relationship with clear manufacturer authorization, installation responsibility and warranties.
For the proposed ~UGX 4 million solar investment at Nansana, the team estimated repayment at roughly UGX 190k–200k/month over two years, depending on the bank's calculation methodology.
The discussion was not simply about obtaining UGX 4 million. The strategic value would be learning the bank's financing process and establishing a financing pathway that could later support much larger deployments such as Pearl Marina.
Dansturn raised the counterargument that debt can encourage progressively larger borrowing and therefore increases risk. Aaron's view was that project-level asset financing can be appropriate where the asset and its project cash flows support the loan and the lender's remedy in a failed project is largely tied to the financed assets.
Working direction: Continue investigating the Stanbic facility rather than dismissing it. The team generally considered 15% potentially workable, although Hillary would prefer a lower rate if one is available.
3. NFE accounting readiness
The financing discussion reinforces the need for NFE's financial records to become audit-ready.
Aaron has started migrating the company's accounting into Zoho Books and needs to finish bringing the records up to date before engaging an auditor.
The team also discussed Esther's role supporting the books. Aaron had proposed a UGX 50,000 monthly stipend, while Esther asked whether she could receive equity instead.
The existing NFE equity-for-work framework requires roughly five hours of regular contribution per month. At the current transaction volume, the bookkeeping work probably does not yet reach that threshold.
Working position: Continue with cash compensation for now rather than allocating equity, while leaving open the possibility of equity if the finance workload grows sufficiently.
4. Nansana battery operation and arbitrage
Hillary raised a concern about whether customer demand could undermine the economics of battery arbitrage.
If customer load exceeds inverter capacity, the inverter may move into bypass/grid operation. This could be particularly important during evening peak periods, when NFE expects battery discharge to reduce grid consumption and improve margins.
The team needs to understand the exact inverter behavior under:
-
available grid power;
-
available battery energy;
-
sufficient battery power capacity;
-
but customer instantaneous load exceeding inverter output capacity.
The team also reviewed recent energy summaries and noticed surprisingly little reported battery discharge, despite known instances where the site has operated on battery.
This raises the possibility of a reporting/algorithm problem rather than an actual absence of discharge.
Decision: Investigate the battery discharge reporting before relying heavily on the existing daily summaries.
The team also agreed that NFE does not need to wait for solar installation before testing battery arbitrage. With grid supply currently relatively stable, this is actually a good opportunity to begin controlled peak-discharge experiments.
5. Phase balancing and low-voltage problem at Nansana
Following the recent phase-balancing work, one customer has reported that high-load appliances such as the microwave/hot plate are not operating properly.
The leading hypothesis is a loose electrical connection, particularly a neutral connection, producing acceptable unloaded voltage but excessive voltage drop once significant current flows.
The site technician was expected to visit the site and:
-
tighten/check all relevant terminals;
-
test voltage;
-
have the customer switch on a significant load such as the microwave;
-
verify that voltage remains stable under load.
The recent balancing work has nevertheless significantly improved phase distribution. The approximate phase allocation is now around:
-
L1: 28%
-
L2: 35%
-
L3: 37%
A further meter transfer could potentially move this toward roughly 31/35/34, but this is not urgent because the current distribution is already substantially better than before.
The additional move requires suitable 16 mm² copper cable, which is not currently available.
6. Improve the physical meter installation
While reviewing the Nansana installation, the team agreed that the current wiring arrangement is functional but not sufficiently clean or scalable for future commercial deployments.
Particular attention should be given to the RS485/Modbus wiring and the general routing of conductors.
The team discussed developing something more analogous to a busbar/distribution arrangement so connections are organized rather than looping and hanging between devices.
Principle: Nansana can remain an experimental installation, but the next installation—particularly Pearl Marina—needs a significantly cleaner and more repeatable hardware design.
7. Pearl Marina engineering proposal
Aaron met with Pearl Marina's engineering/management representatives to understand what would be required for formal approval.
They want a proper engineering proposal showing:
-
the purpose of the microgrid;
-
locations of batteries;
-
proposed solar installation;
-
metering architecture;
-
electrical integration with existing infrastructure;
-
assurance that the installation will not interfere with existing utility equipment;
-
assurance that the roof/building will not be damaged.
They also want the proposal and drawings reviewed by a qualified/certified engineering firm. Multiconsult was mentioned as one firm they already work with and would likely trust.
Dansturn explained that the starting point should be Pearl Marina's existing as-built electrical/MEP drawings. These would allow NFE to overlay the proposed system architecture.
For the solar component, NFE also needs the roof plan. The roof plan establishes available area, while structural calculations or information from the structural engineer will be needed to determine allowable loading from the proposed panels.
Decision: Prioritize completing the Pearl Marina proposal rather than pursuing the other stalled development immediately.
The second project discussed remains potentially viable but construction has slowed because the developer appears to have funding constraints.
8. Additional embedded-systems engineering support
Hillary described another engineer with skills in:
-
C;
-
C++;
-
embedded systems;
-
chip/hardware design.
The team believes this person could be particularly relevant to the IEEE/open-hardware work.
Hillary will introduce him to the material already shared in NFE's IEEE Smart Village collaboration channel, including the previous workshop documentation and NFE's broader generation/capability roadmap.
The goal is not merely to have him study individual technical documents, but to understand NFE's direction toward increasingly open, locally maintainable hardware.
9. Calin meters and EnAccess
The team confirmed that NFE no longer has a strong commercial use for the decommissioned Calin meters.
EnAccess is interested in them for MicroPowerManager integration/testing, particularly because Calin meters are apparently used considerably in West Africa.
Decision: NFE is willing to donate the available used meters to EnAccess provided EnAccess covers shipping.
The meters should be clearly described as used, and EnAccess should understand that NFE cannot guarantee continued access to Calin's hosted AMI/API.
The broader lesson remains that relying on vendor-hosted APIs creates long-term platform risk. NFE prefers equipment with interfaces that can be accessed directly and independently.
10. Smart Metering Crisis Response opportunity
The team discussed the new OSEA/EnAccess Smart Metering Crisis Response initiative following the collapse/distress of major meter providers.
Approximately a quarter-million connections across numerous countries may be affected.
Emergency funding is being used to preserve existing platforms, including attempts to obtain source code and encryption keys so affected operators can continue operating deployed meters.
However, the initiative is also considering what a long-term, vendor-independent architecture should look like.
Aaron has already positioned NFE as a potential contributor.
This fits strongly with NFE's Microgrid OS thesis:
Operators should be able to integrate directly with meters through documented interfaces, while the management layer remains open source and self-hostable if necessary.
There may therefore be both a technical collaboration opportunity and potentially access to catalytic funding.
The team should follow the Discord channel and prepare to contribute to the expected September discussions/workshop, potentially in Nairobi.
Q3 progress
The team reviewed the existing Q3 goals and concluded that substantial progress has been made:
-
Metering: effectively achieved.
-
Outage detection: operational; NFE can identify when grid power disappears and the system transitions to battery.
-
Battery monitoring/control: largely operational, although discharge reporting needs investigation.
-
Arbitrage: technically ready to begin experimental testing.
-
Phase balancing: substantially improved, with one additional optimization possible.
More operating data is still required before some of these can be considered fully validated.

Culture - how we work
Most of our work is asynchronous, this is the best way for people in different timezones, schedules and places to effectively collaborate. The people at Gitlab wrote a good guide on asynchronous work, please go read it.
Here's some tips from Aaron
- Lean on element/matrix to start conversations about something you are inclined to "have a meeting or call" about. You'll be surprised by how much progress you can make on something without scheduling a meeting.
- Expect that progress might feel slower than having everyone in the same room at the same time.
- You need to get better at writing your thoughts and ideas out. We really very heavily on written communication to collaborate
- If you have an idea or suggestion, make use of our bookstack library and create a page for it as we discuss it.

ByLaws
Welcome
This work, "NFE Bylaws", works as the operating agreement for Watt Works Foundation Limited and is a derivative of "Ampled ByLaws and East Bay Permanent Real Estate Cooperative Bylaws" by theselc.org, used under CC BY-SA 4.0.
Our Bylaws
This is the guidebook for NFE. This document explains how shared ownership model works, how decisions are made, and how profit is shared.
These Bylaws provide guidance for Watt Works Foundation Limited (dba NFE), our desire is to empower each other to steward NFE's vision well and go beyond simply following the letter of the bylaws.
We think having the ByLaws in place can be a helpful safety net when conflict inevitably arises but we expect and encourage 1:1 conversational deliberations rooted in our values to be the first tool we reach for to resolve conflicts peacefully.

- Avoidance of accountability Ducking the responsibility to call peers on counterproductive behavior which sets low standards => prevented by Community.
- Inattention to results Focusing on personal success, status, and ego before team success => prevented by Managers of One
- Lack of commitment Feigning buy-in for group decisions creates ambiguity throughout the organization => prevented by Community and Managers of One
Some dysfunctions are not addressed directly by our values; for example, trust is not one of our values. Similar to happiness, trust is something that is an outcome, not something you can strive for directly. We hope that the way we work and our values will instill trust, instead of mandating it from people; trust is earned, not given
Ownership
NFE is owned by the community of people contributing to NFE's mission.
Owners or Members
Owner-member is the term we use to refer to people NFE recognizes as owners or members of the NFE co-operative.
- Each ownership category elects at least 1 and a maximum of 2 representatives on the NFE board. Each board member serves a 2 year term, they serve for a maximum of 2 terms.
- Owner-members take on 3 main categories. Some members can be recognized within more than one category.
Workers
- Workers contribute by investing time and skills to NFE activities they are hired to complete.
- They make most decisions about the day to day operations of NFE but their board representatives vote on the major decisions
- Becoming a Worker-Owner requires 3 things
- Work and report at least 240 hours or 6 months, whichever comes first. This work needs to be regular ie at least 5 hours per month.
- Agreement to the NFE ByLaws
- Approval of at least 2/3 our current worker-owners
Funders
- Funders contribute money to an NFE microgrid project.
- Their board representatives vote on major decisions
- Becoming a Funder-Owner requires 3 things
- Fund at least 10% of the cost Phase 1 of a given microgrid
- Agreement to the NFE ByLaws
- Approval of at least 2/3 our current funder-owners
Customers
- Customers contribute by using and paying for energy via NFE's microgrids
- Their board representatives vote on major decisions
- Becoming a Customer-Owner requires 3 things
- Contributing for at least 12 consecutive months
- Agreement to the NFE ByLaws
- Approval of at least 2/3 our current customer-owners
Please note that NFE membership voluntary. Individuals or organizations can be funders, workers or customers and chose not to apply for member/ownership.
Responsibilities of Owner-Members
- Active participation in NFE activities as prescribed by their membership category
- Voting on admission of new members
Benefits of Owner-Members
- Influencing Major NFE and NFE microgrid decision
- Annual Surplus sharing
- Workers - equal share of NFE's surplus (NFE is a worker-member of every microgrid we operate)
- Customers - proportional share of respective microgrid's surplus, proportional to their contribution
- Funders - proportional share of funded entity's surplus, proportional to their contribution.
- Existing owners get right of refusal to opportunities for new membership as workers, customers or funders.
Suspending Membership
- Ownership is suspended if an owner-member stops contributing and is given at least one warning.
- Ownership is suspended if an owner-member dies or is dissolved or closed in the case of an organization owner.
- The Board otherwise expels an Owner on grounds of actions contrary to the mission and values, as long as the Board uses a consistent, fair, and reasonable procedure for expulsion (provided in writing to the Owners) that gives an Owner a reasonable period of time in which to explain or correct a problem.
Non Owner Community Members
Not all our stakeholders are currently eligible for becoming members but are still part of the community so theoretically could be owners in the future.
- Suppliers - NFE partners with organizations like UEDCL (Macrogrid operator in Uganda), Calinmeter Co a metering supplier and Linux and EnAccess foundations are key software partners. We would like to include them as members but are get to craft a model to that effect.
- Regulators - Electricity Regulatory Authority (ERA) and Uganda National Beurou of Standards (UNBS) are also key stakeholders and part of our community but are currently not eligible for membership.
- Advisors - We have a board of advisors who provide guidance on our business, technology and people model. We may compensate these advisors for their time but they are currently not eligible for membership.
- Donors - These have gifted the co-op resources in cash for in-kind. eg Energy IoT
Board of Directors
This group are the guardians of the NFE mission. They help steer and make all major decisions.
Board Members
- All board members except the CEO are elected by the owner-members
- The Board generally stewards the process by which work is carried out, as opposed to directing the substance of the work.
- CEO is hired by NFE workers and approved by the board
Responsibilities
- Regularly reviewing financials and financial decisions, changes to employee compensation, and periodic budget review.
- Monitoring compliance with the law.
- Reviewing internal policies adopted by Workers.
-
Providing feedback and guidance to workers and Making reasonable inquiry into any concerning activities or decisions by workers.
-
Intervening when the NFE's members engage in overly risky or illegal activity
Board Elections
- Happen every time a board position is open.
- Board terms are a minimum of 1 year and a maximum of 2 years.
- Members will serve for at most 2 consecutive terms.
Board member removal
- A board member may be removed by the members that elected that particular board member
- A board member may be removed if they die or the organization is closed or dissolved.
- CEO may be removed by a simple majority of the board members.
Binding NFE
The Secretary or Chairperson or CEO may sign a document or make a binding commitment on behalf of NFE. The Board may designate other people through a board resolution, to do the same.
Directly Responsible Individuals
NFE is a community owned organization but we rely very little on consensus to make most decisions. Directly Responsible Individuals (DRIs) at NFE own particular projects, initiatives, or activity and make most decisions concerning those areas.
What is a directly responsible individual?
Apple coined the term “directly responsible individual” (DRI). The idea is that every project is assigned a DRI who is ultimately held accountable for the success (or failure) of that project.
They likely won’t be the only person working on their assigned project, but it’s “up to that person to get it done or find the resources needed.”
DRIs may be a lead or senior or associate worker. The selection of a DRI and their specific role will vary based on their own skillset and the requirements of their assigned task. What’s most important is that they’re empowered.
While the DRI is the individual who is ultimately held accountable for the success or failure of any given project, they are not necessarily the individual that does the tactical project work. The DRI should consult and collaborate with all teams and stakeholders involved to ensure they have all relevant context, to gather input/feedback from others, and to divide action items and tasks amongst those involved.
Empowering DRIs
It is important to understand that DRIs do not owe anyone an explanation for their decisions. If you force a DRI to explain too much, you’ll create incentives to ship projects under the radar. The fear of falling into a perpetual loop of explaining can derail a DRI, and cause people to defer rather than working with a bias for action.
We would much rather foster a culture where DRIs are willing to put their ideas in the open. This enables feedback from a broad range of diverse perspectives, which the DRI can take into account and choose how (if at all) it shapes their thinking.
Communication and feedback
A DRI should be able to articulate the objectives, check progress and give and receive feedback. This will ensure the DRI can change direction or plan ahead to avoid any setbacks.
At NFE we communicate and work asynchronously, you can read more about it on this page.
One thing to consider when a DRI needs to give or receive feedback is that they may not be the actual manager of the other members of the team.
DRI, Consulted, Informed (DCI)
Different organizations use different methods of assigning responsibility; one of the most popular is the RACI Matrix, which outlines who the Responsible-Accountable-Consulted-Informed people should be on a decision or project.
GitLab’s implementation of a DRI for decision-making means that we have evolved the RACI matrix to DCI (DRI, Consulted, Informed).
The Responsible and Accountable person is the DRI, the Consulted people are those whose opinions are sought, typically subject-matter experts; and with whom there is two-way communication. and Informed people are those who are kept up-to-date on progress, often only on completion of the task or deliverable; and with whom there is just one-way communication.
Circumstances Requiring the Rare Need for Approvals
- Decisions that impact more than a single project
- Could have large financial impact
- Could present significant risk to the business
- Have business reputation considerations
- Decisions regarding approval or removal of NFE members, NFE project members and their respective board members as
Surplus Sharing
What and why
- After the end of every fiscal year, NFE shall do the following:
- Determine available surpluses for each project for reallocation.
- Allocate some or all surpluses to members, following the procedures described under “How Surplus Is distributed”.
If, instead of surpluses, there are losses, the losses will be allocated in any manner that the Board determines to be fair and equitable, in consideration of the circumstances leading to the loss.
How Surplus is Distributed
- Books are balanced for each project under NFE as well as NFE itself.
- NFE will propose to the board on how to invest the surplus in any of 3 ways in order of priority
- Every project will first pay back the principal contribution from all it's funders.
- The project will then consider how much to reinvest back in the project expansion
- Remaining surplus per project is distributed to it's members equally (workers) or proportionally to contributions for funders and customers.
- Every project will first pay back the principal contribution from all it's funders.
Will & Testament
How NFE will close
Any proposal to sell, dissolve, or liquidate NFE or it's projects must be approved by 2/3 of the board. In such an event, after paying or adequately providing for all debts, liabilities, and repayment to contributors, NFE shall make payments in following the procedures described under “Surplus Sharing”
Defending and Compensating members
NFE shall have the power to indemnify its Workers, Customers, Funders and their agents to the fullest extent permitted by law. NFE shall compensate a Worker, Customer or Funder for any expenses incurred from lawsuits, penalties, fines, and costs of defense if the person incurred these expenses in connection with fulfilling their duties as a Worker, Customer or Funder. This is also called “indemnification.”
However, NFE is not obligated to “indemnify” a person if such expenses arose from a situation where the person stole funds, knowingly received funds they were not entitled to, intentionally committed a crime, or recklessly or intentionally harmed NFE or its members.
Changing Bylaws
Prior to the first Board election, these Bylaws may be changed by approval of a majority of Initial Worker-Owners.
Once a Board has been elected, with exceptions listed below or on a specific Bylaws page, these Bylaws may be changed by approval of 2/3 of Board at a duly called Owner meeting, or by 2/3 of those voting by electronic ballot duly submitted to Owners, so long as a quorum participates. All elections should provide at least 15 days prior notice.
Exceptions include:
- Changes to the Bylaws (including formatting changes) not affecting the decision-making power or financial rights of Members may be made by approval of 2/3 of the Board.
- Each time a page in the Bylaws is amended, the Board Secretary will email a copy of the new Bylaws to all Owners, and will put the Bylaws on the NFE Library. The Library will include an archive of all old Bylaws. NFE's Library software (bookstack) will be used to maintain revision history and comments for more context on why each change was made.

Financial Model Game plan - Q2
🎯 The 3 Goals
-
Microgrid unit economics model
-
Fundraising narrative
-
Stress test your monetization models (Owned vs Partner)
🧭 Phase 1 (Week 1–2): Build Financial Clarity (Foundation)
1) Microgrid Unit Economics Model
What you’re building
A per-site financial model that answers:
“If we deploy one microgrid, does it make money?”
Step 1: Define core inputs
Start simple (don’t overcomplicate):
Costs (CapEx)
-
Battery (e.g., 10kWh setup)
-
Inverter
-
Installation (+20%)
-
Metering hardware
-
Any fixed setup costs
Revenue
-
Avg monthly revenue per household
-
Number of households (e.g., 10 → 100 → 360)
-
Tariff (or effective price per kWh)
Operating costs (OpEx)
-
Maintenance
-
Staff/ops allocation
-
Platform/software (NFE OS)
-
Losses / non-payment buffer
Step 2: Build outputs
You want 5 key metrics:
-
Monthly revenue per site
-
Monthly profit
-
Payback period (months)
-
Gross margin (%)
-
Cash flow over time
Step 3: Answer key questions
-
How long to recover CapEx?
-
What happens if:
-
Usage drops 20%?
-
Costs increase 15%?
-
-
What is your minimum viable scale per site?
Deliverable
👉 A simple Google Sheet model (I can help you structure this next)
🧭 Phase 2 (Week 2–3): Stress Test Your Two Models
Now apply the model to your two strategies:
Model A: NFE-Owned Microgrid
What to evaluate
-
Total capital required per site
-
Revenue collected directly
-
Payback period
-
Cash constraints (how many sites you can deploy)
Key insight you want:
“How fast can we scale before we run out of cash?”
Model B: Partner-Owned Microgrid
What to evaluate
-
Your revenue:
-
Flat fee per customer
-
+5% of electricity sales
-
-
Your costs:
-
Ops + maintenance
-
Key insight:
“Is this a high-margin, low-capex business?”
Compare side-by-side
|
Metric |
NFE-Owned |
Partner Model |
|---|---|---|
|
Capital required |

Strategic output
You should be able to say:
-
“We lead with Partner model to scale fast”
-
or
-
“We prioritize Owned model for long-term value”
👉 This becomes core to your pitch
🧭 Phase 3 (Week 3–4): Build Your Fundraising Narrative
Now turn your numbers into a story investors understand
1) Problem (you already do this well)
-
Unreliable grids
-
Diesel backup risks
-
Growing urban demand
2) Solution (tighten this)
-
“Community microgrids that turn backup power into primary infrastructure”
3) Business Model (now backed by numbers)
Use your model to clearly show:
-
Revenue per site
-
Margin
-
Payback
4) Traction
-
Pilot (10 homes)
-
Phase 2 (100 homes)
-
Pipeline (360 apartments)
5) Scaling Strategy (THIS is key)
From your analysis:
Example:
-
Phase 1: Pilot + validate
-
Phase 2: Scale via partner model
-
Phase 3: Selectively own high-value sites
6) Use of funds
Your model should let you say:
-
“$300K deploys X sites”
-
“Each site generates $Y/month”
-
“Break-even in Z months”
Deliverable
👉 A clean 8–10 slide pitch (or 1–2 page memo)
🧭 Phase 4 (Week 4–6): Add Financial Discipline
This replaces what a CFO would start doing.
1) Monthly financial tracking
Track:
-
Revenue per site
-
Cost per site
-
Collection rates
-
Downtime
2) Define 5 core KPIs
For NFE, I’d suggest:
-
Revenue per customer
-
Cost per customer
-
Payback period per site
-
System uptime (%)
-
Collection efficiency (%)
3) Cash planning (critical)
Build a simple view:
-
Cash today
-
Monthly burn
-
Months of runway
⚠️ Critical mindset shift
You’re moving from:
“We are building microgrids”
to:
“We are deploying capital into energy assets that must return money”
That shift is what investors care about.
🧩 How this all connects
-
Unit economics → proves viability
-
Model comparison → defines strategy
-
Narrative → unlocks capital
-
Tracking → sustains growth
