Solar PPA for schools & education in London

Term-time demand, summer export

A London school's electricity use follows the academic calendar — high through term, with lighting, IT suites, catering and heating controls all drawing power, then falling away across the summer holidays. That rhythm shapes the solar case: term-time generation offsets daytime consumption, while the lighter summer surplus is exported, typically earning through a SEG arrangement rather than sitting idle. For a capital-starved academy or multi-academy trust, a power purchase agreement removes the funding hurdle outright — the provider installs and owns the array, and the school simply buys the electricity it produces.

What the sector figures look like

School arrays are modest by commercial standards, usually 50–250kWp, and PPA unit rates for education land in the 13–17 p/kWh band — commonly under the day-rate a school pays now. Commercial energy bills in the capital run high, averaging around £95,000, well above the other cities we track, so even a mid-sized secondary can see savings within the sector's £5k–£40k a year range. The precise figure turns on roof area, orientation and how much of the load falls in term time.

Policy and grid backdrop

The London Plan's Policy SI 2 expects rooftop solar on major commercial development, and the London Energy Efficiency Fund has financed public buildings, schools among them. Distribution across the capital is handled by UK Power Networks, so a connection check is the sensible first technical step for any site, from Croydon and Bromley out to Watford or Slough. The Greater London Authority holds a 2030 net zero goal.
