Our early work in designing and implementing modern energy markets and subsequently guiding the sector in the push to decarbonisation means CMS is not only a transactional or project adviser to the sector, but uniquely placed to help shape its present and future. 

CMS has a market-leading energy storage practice with extensive experience advising in relation to a variety of storage projects, including standalone, co-location and behind-the-meter projects, across a range of technologies.

Our recent experience related to energy storage includes advising:

The planned project in Capenhurst, Chester, would be “Europe’s biggest” grid-connected battery when it begins operations in April 2022.
  • Penso Power on its joint venture with BW Group to fully fund the build-out of Penso Power’s pipeline of more than 3GWh of large-scale battery storage projects in the UK.
  • Statera on the disposal of a 300MW pre construction battery storage portfolio. Our role included drafting and advising on linked EPCM and O&M arrangements.

  • Eelpower on various aspects of its energy storage portfolio, including project acquisitions, battery storage supply arrangements, financing structuring and revenue stream arrangements, including participation in the Balancing Mechanism.
  • Low Carbon on the development of two battery storage projects with a combined capacity of 50MW, including advising on the EFR contract, negotiating the bespoke EPC and O&M arrangements and advising on the resulting joint venture with VPI Immingham.
  • Anesco on the purchase of four c.10MW battery storage projects from Green Hedge that were pre-qualified for the 2016 T-4 Capacity Market, including considering Capacity Market and grid connection issues.
  • Equinor on the co-location of a 1MWh lithium-ion battery with the hywind floating offshore wind farm, including considering issues in relation to the RO and the related offtake arrangements.
