Midlands university campus: 1.6MWp blended capital + green loan structure

Project overview

A Midlands university with a four-building campus footprint completed a 1.6MWp solar deployment using a structurally interesting blended finance approach. Direct university funding faced charity-tax constraints (the institution couldn't directly capture corporation-tax allowances given its charitable status). Project was therefore structured through the university's wholly-owned trading subsidiary, which holds the solar assets, claims the tax allowances, and licenses electricity back to the university through a long-term internal supply arrangement.

The challenge

Three complex constraints. First: charitable status meant the university itself could not benefit from the 50% FYA or AIA — those allowances require profit-paying counterparty. Second: estate complexity — the four buildings under consideration had different age profiles (60-year-old academic block, 1990s lecture theatre, 2010s research facility, 2020s student accommodation) requiring different structural and DNO approaches. Third: scale meant capital-purchase-only would have stressed the university's reserves position; a blended structure was needed.

Structure and economics

The university's wholly-owned trading subsidiary (a profit-trading company existing for catering, conference, and ancillary commercial activities) acquired the solar assets. £600k cash from subsidiary working capital plus £700k green loan over 12 years at 5.8% APR. The subsidiary claims the 50% FYA on the qualifying spend and the special-rate pool on the residual — net tax saving ~£185k year one across the £1.3m capex. The subsidiary licenses the electricity to the university at ~14p/kWh (below grid 22p, above subsidiary cost-of-supply) — both parties capture value.

How we got there

1. Step 1

   Q1: Multi-building site survey across the four candidate buildings. Two excluded from the original five-building scope due to listed-building status (academic block) and roof condition (would have required £180k structural reinforcement, ruling out economic case).

2. Step 2

   Q2: Tax structure review with university's corporate tax adviser. Trading subsidiary route confirmed as the practical structure for FYA capture. Internal supply agreement drafted.

3. Step 3

   Q3: Green loan competitive process across four green-debt lenders. Selected on rate, term flexibility, prepayment, and charity-related security structures.

4. Step 4

   Q4: Phased installation — student accommodation first (summer downtime period), research facility second, lecture theatre third, larger main campus building last.

5. Step 5

   Year-2 Q1: All four buildings commissioned and producing. Monitoring portal integrated with university's estates management dashboard.

Outcome

Year-one combined output: 1,650MWh across the four buildings (varying yield by orientation and shading). Direct self-consumption ~88% across the day-heavy university demand profile. Year-one saving: £325k. Subsidiary tax saving on FYA/AIA: £185k year one. Internal supply price retained subsidiary trading margin while providing university below-grid electricity. Net 25-year cash benefit projected at £6.4m across the structure.

What this case taught us

• Charitable institutions including universities, large NHS trusts (where charitable arms exist), and faith-based property owners face structural constraints on direct capital allowance capture. Trading-subsidiary structures are the practical route — but they require active corporate tax planning.
• Phased delivery on multi-building campuses lets installation methodology be refined across the project. The fourth building install was 18% faster (per kWp) than the first, reflecting accumulated learning.
• Blended capital-and-debt structures work well for complex institutions with multiple capital sources and constraints. Pure capital-purchase or pure-debt rarely fits the institutional context as well as a thoughtful blend.
