Worked example: 320kWp PPA Across a Cornwall Hotel Chain
An illustrative 320 kWp hotels solar PPA: at 14.0 p/kWh over 20 years, the modelled year-1 saving is £28,000.
Illustrative example — not a real deal
This is a hypothetical worked example, written to show how a solar PPA's numbers work for this kind of site. The site, the operator and every figure are illustrative: the tariff and term sit inside this site's indicative bands and the saving is modelled from them. It does not describe any real organisation, and no contract is claimed.

An anonymised Cornish hospitality group
This representative example is drawn from independent hospitality: a small Cornwall hotel group — four properties, around 240 rooms between them, one a five-star country house and three coastal three-star sites. Energy was running at roughly 7% of revenue, and the commercial pressure was coming from the booking platforms. Online travel agents had begun surfacing sustainability credentials, and a major platform's climate filter was quietly demoting properties that could not show progress. For a business that lives on visibility, that was reason enough to act.
Aggregating four very different roofs
In this scenario the group signs a single 320 kWp PPA spanning all four hotels — the largest roof taking 140 kWp, the smallest just 45 kWp — over a 20-year term at 14 p/kWh. Aggregating mixed sites under one agreement spreads the provider's fixed costs and gets smaller roofs financed that would never justify a standalone deal. Choosing a provider comfortable with multi-site hospitality portfolios matters here; the provider directory is the place to start.
Where heritage capped the ambition
Not every roof could carry its full potential. The five-star country house was Grade II listed, so panels were confined to a lower stable-block roof and the site ultimately took only about half its planned capacity. Heritage constraints are common in this sector and are best modelled early — the savings calculator lets you test a reduced array before committing.
Indicative outcomes
For this illustrative group the first year brought:
- Around £28,000 in electricity savings across the four hotels.
- Eligibility for the booking platform's climate filter, protecting search visibility.
- Regional hospitality trade-press recognition for the group's sustainability move.
At 14 p/kWh the tariff sits at the higher end of the commercial range, which is typical for smaller, mixed-site portfolios — the pricing page explains why scale and covenant strength pull the rate down.
