Our UK ElectraTherm fleet: March 2026 map

This map shows where ElectraTherm ORC Power Modules were installed across the UK as of March 2026. Each marker is a site, sized by nameplate capacity: blue for 75 kW units and red for 125 kW units.

3,750 kW of installed capacity

Together, the fleet adds up to 3,750 kW of nameplate capacity. The sites stretch from central Scotland to the South West, with clusters across Yorkshire, the North West, the Midlands, Gloucestershire and South Wales.

Proven, not niche

ElectraTherm ORC is an established way to turn waste heat into electricity in the UK. These units run on biomass and other waste heat sources, and Kool Bricks services and maintains almost 50 of them. We also bought, installed and still operate the first ElectraTherm ORC in the UK at our own site.

That hands-on fleet experience, together with ElectraTherm's 2M+ hours of fleet run data, sits behind every output estimate we give.

Where it started: the ElectraTherm 4400B

Before today's Power Modules, there was the ElectraTherm 4400B. This video shows the older machine in action.
