Six disciplines. One contractor.

All services on one page

We cover the whole life cycle of an energy project — from the first calculation to repowering fifteen years on. Click a service to read the detail.

How we work

We develop, build and operate.

Three phases, one responsibility. The investor deals with one team from day one to the last year of the asset’s life.

01

Develop

Study, 3D design, yield model, permits and grid connection agreement. A project ready to build or to finance.

02

Build

Turnkey EPC with Tier-1 components, in-house installation crews and site supervision through to successful energisation.

03

Operate

24/7 monitoring, preventive maintenance, repowering. We keep the plant’s yield at its maximum for its whole lifetime.

Intelligent energy management

Hardware is only half of it. We give it a brain.

The Smart A.I. Box links your PV, battery, heat pump and EV charger into one network and decides every fifteen minutes what is most profitable.

  • Buys when electricity is cheapest
  • Sells surplus in the most expensive hours
  • Plans around the weather and yield forecast
  • Cloud app control from anywhere
