Cotswolds boutique hotel group: 480kWp across four sites under PPA

Project overview

A Cotswolds boutique hotel group operating six properties — four with strong roof structures and two with planning constraints (listed buildings and conservation area) — deployed 480kWp solar across the four eligible sites under a 20-year Power Purchase Agreement. The hotel group retains zero ownership of the solar systems; a third-party developer installed, owns, and operates the systems and sells electricity to each hotel at a fixed-but-discounted tariff.

The challenge

The hotel group had been considering solar for three years but was structurally blocked. Capital purchase was unavailable due to debt covenants on the property portfolio (refinanced 2022 with restrictive new-debt clauses). Green loans were similarly precluded. Operating leases were considered but the implied rate (8.5% effective) made the case marginal. The hotels had visible decarbonisation pressure from corporate event clients but were running out of internal options.

Structure and economics

Specialist hospitality-PPA developer funded the £384,000 turnkey installation across the four sites. PPA terms: 20-year fixed-rate-with-RPI tariff at 16.5p/kWh (versus prevailing grid rate 23.5p), so each hotel saves 7p/kWh on consumed solar. Group-level annual saving in year one: £82,000 across the four sites. Saving grows at 2.0% real annually (RPI-linked tariff escalator) versus expected grid-tariff inflation of ~2.5% real, meaning the spread widens over the contract life.

How we got there

1. Step 1

   Q1: Multi-site feasibility review across all six hotels. Two ruled out for structural and planning reasons — solar deemed not financially viable for those sites alone.

2. Step 2

   Q2: Capital structure review with hotel group CFO confirmed debt covenant constraint on direct capex. PPA structure recommended as the practical route to project viability.

3. Step 3

   Q3: PPA developer screening across three specialist hospitality PPA providers. Selection on price, contract quality, exit terms, and counterparty financial covenant.

4. Step 4

   Q4: Lease provisions amended with each property's legal team to allow third-party solar installation. Property-level PPA contracts executed with each hotel as offtaker.

5. Step 5

   Year-2 Q1-Q2: Phased installation across the four sites, sequenced to minimise off-season disruption.

6. Step 6

   Year-2 Q3: All four sites commissioned and producing. Group-level monitoring portal live.

Outcome

Year-one combined cash benefit: £82,000 across the four sites. The hotel group avoided £384,000 capex outlay (which would have been precluded by debt covenants in any case). Net 25-year saving projected at £2.4m versus £4.1m if the same systems had been capital-purchased — the PPA developer captures the difference as their return on capital.

What this case taught us

• Capital-constrained hospitality groups have very limited options outside PPA — operating lease pricing rarely beats PPA economics for the same risk profile.
• Listed-building and conservation-area constraints often eliminate ~30% of group portfolios. The remaining sites can still produce material group-level savings.
• Long-tenure PPAs (20 years) are essential to the developer business model — shorter terms (10 years) typically aren't available because the developer cannot recover capex within the period at acceptable IRR. Hotels uncomfortable with 20-year contractual horizons should reconsider whether PPA is the right structure.
