UEC Energy structures and delivers fully funded solar PV and battery energy storage system (BESS) installations with no upfront capital requirement. Every project is backed by full project finance — covering design, supply, installation, commissioning, monitoring, and ongoing O&M — across a range of flexible commercial structures tailored to client objectives, risk appetite, and term preference.
Battery Storage & Dynamic Trading
All BESS installations include smart energy management software enabling dynamic trading across multiple revenue streams:
⚡ Revenue Streams
- Frequency Response (FFR / Dynamic Containment / Dynamic Moderation)
- Balancing Mechanism & Short-Term Operating Reserve (STOR)
- Wholesale arbitrage — charge overnight at low-rate tariffs, discharge at peak
- Intelligent export management — maximise grid export revenue at optimal pricing windows
Revenue from dynamic trading is treated differently depending on the financing structure selected — see the options below.

Option Details
1. 25-Year Power Purchase Agreement
The longest-term PPA is inflation-linked at approximately 3% variable per annum, providing a low opening unit rate that rises gradually in line with inflation over the life of the agreement.
All export and ancillary trading income accrues to the project funder.
Best for: Organisations seeking long-term price certainty relative to grid rates, with a fully off-balance-sheet structure and no residual risk. Suitable for large consumption profiles such as schools, care homes, and industrial operators.
2. 15-Year Fixed-Rate PPA
A 15-year fixed-rate PPA — the rate is locked for the entire term with no escalation, providing complete cost certainty for on-site consumption. Export and BESS trading income remain with the funder.
Best for: Organisations that prefer a guaranteed, predictable unit rate over the medium term and anticipate estate or strategy changes beyond 15 years, while still requiring a straightforward off-balance-sheet arrangement.
3. Operating Lease
A structured lease of the solar PV and BESS assets at a fixed or RPI-linked monthly rental. Export revenue and trading income may be shared by negotiated split. Recognised under IFRS 16 for larger entities.
Typically 5–10 years with options to renew, extend, or purchase.
Best for: Housing associations, commercial landlords, and corporates with specific accounting requirements.
4. Subscription
A subscription model charges a fixed monthly fee covering the full system — hardware, installation, monitoring, maintenance, and insurance.
Critically, the client retains 100% of all export revenue and BESS dynamic trading income, offering the highest potential financial return of all zero-capex options.
Best for: Well-metered, export-capable sites where the client wishes to maximise total energy income.
