Our Partnerships

We partner with renewable energy investors to help them achieve optimum performance and financial returns.

Following the successful completion of Bumpers 2, a 12MW solar farm in Buckinghamshire, we have partnered with Gresham House to develop, build and operate a further 200MW portfolio of new solar projects. We have also completed 57MW of solar and storage projects in the UK and Europe for Shell New Energies, a division of Shell that invests in new and fast-growing segments of the energy industry.

We currently have 250MW of battery storage projects and 70MW of solar capacity under construction with three leading investors.

Anesco’s pipeline of new projects is strong, with planning permission having been secured been approved for 300MW of solar and storage opportunities as part of a 3GW pipeline of new development projects.
