Powering a more resilient energy future
We build the reliable, on-demand power a renewables-led system needs, today and through the energy transition.
Haldane Energy is developing large-scale dispatchable power to keep the UK’s electricity supply secure as renewables grow.
Our dual-fuel power stations run on natural gas from the network and hydrogen from our co-located electrolysers, stored in salt caverns. Developed in phases, they increase their use of hydrogen over time.

Our large scale dispatchable power will:
We aim to deliver the dispatchable power the UK depends on, with dual-fuel capability built for the energy transition, attracting inward investment and supporting a resilient, future-ready energy economy.

Part of Windward Energy, a GB-wide, next-generation power business with the scale and backing to take major energy infrastructure from development through to delivery. Windward operates three businesses spanning renewable generation, grid networks and dispatchable power, each built from the ground up.
Haldane Energy’s sister companies are Bute Energy and Green GEN Cymru. Bute Energy is the UK’s largest independent onshore wind developer, with a pipeline of over 2GW across Wales. Its first wind farm is now in construction, after becoming the first onshore wind project in Wales to reach financial close in a decade. Green GEN Cymru is an Ofgem-licensed independent distribution network operator (IDNO) planning to build over 300km of new grid infrastructure.
