Core proposition
NFE sells reliable electricity as a service.service Customersat pay for electricity, not equipment.

## Core terms

### RPM — Reliable Power Microgrid
NFE's microgrid product for improving electricity reliability while progressively adding storage, solar generation, controls, and eventually customer ownership options.

### EaaS — Energy as a Service
A model in whichapproximately the customercustomer's buys electricity/service instead of purchasing the underlying batteries, inverters, solar panels, and controls upfront.

### C&I — Commercial and Industrial
Commercial and industrial electricity customers such as offices, schools, churches, clinics, hotels, apartments, supermarkets, warehouses, and factories.

### SLA — Service Level Agreement
The contractual performance commitment NFE makes to a customer, potentially covering protected load, backup duration, availability, response time, maintenance, and exclusions.

### PPA — Power Purchase Agreement
A contract under which a customer buys electricity from a generator or energy supplier. RPM has some PPA-like characteristics but also includes reliability, storage, monitoring, controls, and lifecycle management.

### TOU — Time of Use
A tariff structure in which the price per kWh varies by period, such as peak, shoulder, and off-peak.

## Technical terms

### PV — Photovoltaic
Solar-electric generation using photovoltaic panels.

### BESS — Battery Energy Storage System
The complete battery-storage system, including battery modules, controls, protection, communications, and supporting equipment.

### LFP — Lithium Iron Phosphate
A lithium-ion chemistry commonly used for stationary storage because of its cycle life and thermal stability.

### EMS — Energy Management System
The software/control layer that decides how energy flows among solar, battery,applicable utility grid,tariff. generator, and customer loads. For NFE, this is part of the Microgrid OS.

### EPC — Engineering, Procurement and Construction
The scope or contractor responsible for system design, equipment procurement, installation, and commissioning.

### kW — kilowatt
A measure of instantaneous power. Important for inverter and peak-load sizing.

### kWh — kilowatt-hour
A measure of energy consumed or stored over time. Important for billing and battery sizing.

### kWp — kilowatt-peak
The rated DC capacity of a solar PV array under standard test conditions.

### DoD — Depth of Discharge
The percentage of nominal battery capacity that is allowed to be used.

### RTE — Round-Trip Efficiency
The percentage of energy put into a battery that can later be recovered.

## Cost and operating terms

### CAPEX — Capital Expenditure
The upfront investment required to deploy the RPM: battery, inverter, PV, mounting, switchgear, controls, installation, commissioning, contingency, etc.

### OPEX — Operating Expenditure
Recurring costs required to run the RPM after installation.

### O&M — Operations and Maintenance
Monitoring, inspections, cleaning, fault response, repairs, warranty management, and component replacement activities.

### Lifecycle Reserve
Money set aside over time for major future equipment replacement, especially batteries and inverters.

### LCOE — Levelized Cost of Energy
Lifetime cost of electricity generation divided by lifetime electricity produced.

### LCOS — Levelized Cost of Storage
Lifetime cost of storing and delivering electricity from a battery.

## Investment and finance terms

### IRR — Internal Rate of Return
The annualized return implied by a project's projected cash flows. It accounts for both how much cash is generated and when it is generated.

**Project IRR** measures the return from the RPM asset before financing.

**Equity IRR** measures the return to NFE/investors after debt financing and debt service.

### NPV — Net Present Value
The present value of future project cash flows after discounting them at a required return.

### ROI — Return on Investment
A simpler return measure comparing profit with investment. Unlike IRR, basic ROI does not properly account for timing.

### WACC — Weighted Average Cost of Capital
The blended cost/required return of debt and equity financing.

### CFADS — Cash Flow Available for Debt Service
Project cash available to pay loan principal and interest after defined operating costs and reserves.

### DSCR — Debt Service Coverage Ratio
**DSCR = CFADS ÷ Debt Service**

Example: if CFADS is UGX 24.5m/year and annual debt service is UGX 13.9m/year, DSCR is about **1.76×**.

### DSRA — Debt Service Reserve Account
Cash held specifically to cover future debt payments if project cash flow temporarily falls short.

### LLCR — Loan Life Coverage Ratio
Present value of CFADS during the remaining loan term divided by outstanding debt.

### PLCR — Project Life Coverage Ratio
Similar to LLCR, but uses cash flows over the remaining project life.

### Debt Tenor
The length of time over which a loan is repaid.

### Leverage
The proportion of project cost financed with debt.

### Sponsor Equity
Capital contributed by NFE and/or its equity investors.

### SPV — Special Purpose Vehicle
A separate legal entity created to own and finance a project or portfolio of RPM assets.

## Risk and contract terms

### Bankability
The degree to which a project has predictable cash flows, enforceable contracts, acceptable risks, and returns sufficient for lenders or investors to finance it.

### Volume Risk
The risk that a customer consumes less electricity than forecast.

### Credit Risk
The risk that a customer cannot or does not pay its electricity bill.

### Minimum Energy Commitment
A contractual commitment by the customer to purchase at least a defined quantity of electricity over a period.

### Take-or-Pay
A stronger minimum commitment where the customer pays for energy used, not equipment. NFE owns, operates, maintains and replaces the reliability infrastructure, with an optional Phase 4 path to ownership.



1. Purpose of this document

This pack is intended to support the NFE weekly team review on the emerging Commercial RPM model. It captures the current product logic, a worked Phase 2 case, preliminary financing structure, customer-screening thresholds, model definitions and the decisions still required before NFE treats the model as investment-ready.

  • Reference customer: Worship Harvest Ministries, using customer-supplied UEDCL bills and account movements.

  • Benchmark: Sawa Energy's Bellavista solar + battery lease-to-own proposal was used as a commercial-structuring reference, not as NFE's pricing model.

  • Status: Pre-feasibility / internal investment model. Site metering, EPC quotations, regulatory confirmation and credit underwriting remain required.

2. The Commercial RPM model

   

Phase

Customer outcome

NFE activity

1 - Measure & Manage

Establish an evidence-based load and outage baseline.

Install interval metering, characterize peak/shoulder/off-peak demand, identify critical loads and quantify current backup costs.

2 - Reliable Power

At least the contracted minimumcritical quantityload whetherremains orpowered through normal outages.

Deploy storage, inverter/control infrastructure and enough PV to help finance the reliability layer.

3 - Energy Optimization

Lower grid dependence and optimize energy cost/reliability.

Expand PV/storage, optimize dispatch and progressively use the grid as a secondary source.

4 - Ownership Option

Customer may choose to acquire the installed system.

Execute a predefined buyout/transfer mechanism that first protects any outstanding lender obligations.

3. Worship Harvest: current evidence base

   

Metric

Working value

How to treat it

Average monthly electricity consumption

~6.9 MWh/month

Derived from four supplied detailed UEDCL bills; use as the current baseline, not a guaranteed future load.

Annualized electricity consumption

~82.9 MWh/year

Used for the current screening model.

Observed load mix

~29% peak / 52% shoulder / 19% off-peak

Useful because the 18:00-24:00 peak period exactly matches the requested six-hour backup window.

Recent utility payment behavior

Bills in the supplied statement were substantially/fully cleared within the billing cycles shown.

Positive early credit signal, but not a substitute for full credit underwriting.

Phase 2 reliability target

At least 6 hours during 18:00-24:00

Must be validated with interval data and critical-load definition.

4. Preliminary Phase 2 technical design

   

Component

Working design

Rationale

LFP battery

120 kWh nominal

Provides headroom above historical average peak-period energy, plus usable-depth, conversion-loss and reliability reserve allowances.

Hybrid inverter

50 kW, three-phase

Provides headroom for instantaneous demand and motor/other transient loads that monthly bills cannot reveal.

Solar PV

36-40 kWp preferred

PV is not needed to make a 6-hour evening battery work technically; it is consumed.included because avoided daytime/peak grid purchases finance the reliability infrastructure.

###Controls Early/ TerminationEMS

Payment

NFE Microgrid OS + metering

Required for dispatch, monitoring, billing, alarms, asset health and later portfolio management.

 

Important engineering caveat
A
Monthly predefinedbills paymentshow ifenergy consumption, not instantaneous power demand. The 50 kW inverter and 120 kWh battery are preliminary. Phase 1 interval metering should validate the maximum kW demand, critical-load profile, event-day behavior, battery charge window and site power quality before procurement.

Metric

Illustrative result

Interpretation

Senior debt

~UGX 78.5m

55% of ~UGX 142.8m CAPEX.

NFE/investor equity

~UGX 64.3m

Before DSRA funding.

Annual debt service

~UGX 13.9m

Assumes 12% debt over 10 years with level annual debt service.

Base DSCR

~1.76x

CFADS / scheduled debt service. Provides material cushion above 1.0x.

6-month DSRA

~UGX 7.0m

Liquidity buffer equal to half a year of scheduled debt service.

Unlevered project IRR

~15.1%

Return on the project before debt financing, under the current simplified 15-year constant-real-cash-flow assumptions.

Equity IRR

~15.6-16.0%

Approximate result depending on how/when DSRA is released.

 

Financing conclusion
The economics are much more attractive with long-tenor concessional or project debt than with ordinary high-cost commercial lending. Early RPMs should prioritize lower leverage and strong coverage rather than maximizing debt. Portfolio financing can increase leverage later after operating history exists.



8. Customer qualification threshold

The current model suggests a theoretical break-even/target-return threshold near 1.5 MWh/month for a customer with a load shape similar to Worship Harvest. For sales screening, NFE should use a more conservative threshold because fixed costs, site complexity, credit quality, solar yield and load shape vary.

  

Monthly usage

Screening interpretation

< 1.5 MWh

Usually below current economic threshold for a stand-alone Commercial RPM Phase 2.

1.5-2.0 MWh

Possible but marginal; requires especially favorable site/load/credit conditions.

>= 2.0 MWh

Recommended first-pass Commercial RPM qualification threshold.

>= 3.0 MWh

Strong candidate, subject to solar-compatible demand and site/credit quality.

Worship Harvest: ~6.9 MWh

Comfortably above the consumption threshold; the remaining work is engineering, regulatory, credit and financing validation.

9. Bankability risks and mitigations

   

Risk

Why it matters

Proposed mitigation

Volume risk

Customer pays for energy used; NFE debt service does not fall if customer consumption contracts.

Lower leverage for early sites; strong customer underwriting; termination protection; consider a modest minimum annual energy commitment only where financing requires it.

Tariff/indexation risk

A fixed customer tariff can become uneconomic as utility prices and operating costs change.

Contractually mirror the applicable utility tariff.tariff structure or define a transparent indexation formula.

###Credit/collection Criticalrisk

Load

Energy revenue is the project cash flow.

Credit review, payment history, deposits, remote metering, clear default/curtailment procedures and diversified portfolio.

Technology/lifecycle risk

Battery/inverter replacement can destroy economics if omitted.

Explicit replacement reserve, manufacturer warranties, standardized equipment and remote health monitoring.

Performance risk

PV yield or storage availability may underperform assumptions.

Conservative yield, performance guarantees where available, commissioning tests and reserve margins.

Regulatory risk

The electricallegal loadstructure for on-site generation/resale/EaaS must be valid.

Obtain Uganda-specific regulatory/legal confirmation before financial close and standardize the compliant contract structure.

EPC / construction risk

Cost overruns or poor installation can impair returns and safety.

Competitive RFQ, fixed-price scope where feasible, commissioning acceptance tests and appropriate EPC warranties.

10. Proposed cash-flow waterfall

  1. Customer pays NFE for metered electricity under the EaaS contract.

  2. NFE/SPV pays utility/grid energy costs and other variable energy costs.

  3. NFE/SPV funds routine O&M and operating expenses.

  4. NFE/SPV funds the agreed battery/inverter lifecycle reserve.

  5. Remaining operating cash is CFADS for lender purposes under the internal screening model.

  6. Scheduled senior debt service is paid.

  7. Required DSRA top-up, if any, is funded.

  8. Residual distributable cash is available to NFE / equity investors.

11. Decisions requested from the NFE team

   

Decision

Current working position

Team discussion

Commercial Phase 2 product definition

Battery reliability + enough PV to support the economics.

Confirm whether this becomes the standard default or remains site-specific.

Customer tariff promise

Utility-equivalent tariff, not an equipment lease.

Define exactly which utility charges are mirrored and how tariff changes flow through.

Reliability promise

6-hour outage coverage for contracted critical load.

Decide whether the product SLA should be framed as hours, availability %, or both.

Debt strategy

50-55% debt for early projects; target <=12%, 10+ years.

Confirm acceptable leverage and target lender categories.

Customer minimum usage

No hard minimum in the preferred customer proposition.

Decide whether a soft minimum annual energy commitment is acceptable when a lender requires it.

Phase 4 ownership

Predefined buyout from a stated year, subject to lender discharge.

Agree lockout year and buyout methodology.

Commercial screening threshold

>=2 MWh/month first-pass screen.

Confirm and add load-shape, credit and site criteria.

Portfolio/SPV structure

Preferred long-term financing architecture.

Decide when to establish the first RPM project/portfolio SPV.

12. Immediate next steps

  1. Install/obtain interval metering for Worship Harvest and identify critical vs. discretionary loads.

  2. Request at least two local EPC/vendor quotations for the 120 kWh / 50 kW / 36-40 kWp design range.

  3. Refresh the model with quoted CAPEX, warranty terms, installation scope and realistic replacement assumptions.

  4. Confirm the legally compliant Uganda EaaS / on-site resale structure and required permits/licences/exemptions.

  5. Complete a customer credit review and obtain a longer utility-payment history if available.

  6. Develop the standard Commercial RPM EaaS term sheet: tariff indexation, SLA, deposit, termination, access, insurance and Phase 4 buyout.

  7. Prepare a lender-facing model with monthly cash flows, debt amortization, downside cases and covenant tests.

  8. Build a pipeline scorecard so NFE can screen commercial leads consistently before spending engineering time.
