Energy storage

We are one of only a few UK law firms with the specialist expertise to advise on all clean energy schemes, with an outstanding reputation for innovation and a track record of working with some of the most entrepreneurial companies in the sector.

We’ve been instrumental in tackling the legal issues around energy storage projects and have experience of advising across the project life-cycle including:

  • We advised on nearly 40% of those sites that were awarded contracts in the National Grid EFR tender.
  • Acting on a significant number of the projects that were successfully awarded contracts in the National Grid Capacity Market auction.
  • Working with clients in relation to behind-the-meter storage projects both on an owner / occupier basis and where there is a third party direct off-taker.
  • Advising in relation to the development of bankable models for energy storage projects on a debt funding basis.
  • Providing go-to market advice to clients who are looking to co-locate energy storage with an existing project and the potential impact on subsidies.
  • Advising private and public clients in relation to a number of prospective sites for large scale grid connected stand-alone battery storage projects.
  • Working with clients in relation to the interaction of different National Grid revenue streams and revenue stacking.
  • Advising clients under taking energy storage plus solar developments with private wire PPA arrangements.

We are associate members of the Electricity Storage Network.


  • Advising Santander in relation to a landmark transaction signalling that the energy storage market is now ripe for debt funding. The investment sees Santander provide a £28.5m facility to Battery Energy Storage Solutions Limited. We provided Santander with end to end support and advice, including advising on the terms and structure of the debt finance.
  • Advising The Renewable Infrastructure Group on its acquisition of the 20MW Broxburn energy storage plant in Scotland - one of the first large-scale commercial power storage projects in the UK.
  • Advising Guinness Asset Management on its investment in one of the UK's first solar plus battery storage projects. The project will see a Tesla battery added to one of the UK's largest rooftop solar installations at the Telford distribution centre of Lyreco, which was also developed by EvoEnergy and is owned by funds managed by Guinness Asset Management.
  • Advising Anesco on a share sale to Mongoose Energy. The deal will fund a 15MW solar-plus-storage project at Anesco's Drayton Manor solar farm. The project comprises three separate arrays, with FIT / ROC revenue streams, which have battery systems retrofitted.

These projects have recently been completed and will deliver a quarter of the EFR 200MW capacity secured by National Grid. These sites have also been awarded capacity market contracts.
