A subsidiary of Japan’s NEC Corporation has announced it has completed the commissioning of a total of 50 MW of energy storage projects in the UK.

EC Energy Solutions (NEC ES) will team up with VLC Energy, a joint venture between Low Carbon, a renewable energy investment company, and VPI Immingham, owner of one of the largest combined heat and power plants in Europe and part of the Vitol Group.

The 50 MW portfolio, which is now fully operational and includes a 40 MW facility in Glassenbury in Kent and a 10 MW installation in Cleator in Cumbria, represents the largest portfolio of utility-scale battery energy storage systems connected to the UK grid.

The Cleator and Glassenbury sites secured two contracts with National Grid in August 2016 for battery energy storage systems to provide Enhanced Frequency Response (EFR) to the UK system operator.

NEC ES provided turnkey engineering, procurement and construction (EPC) services which included its GSS® end-to-end grid storage solution, and was contracted to operate the sites to provide the EFR service directly to National Grid. Energy storage operation for EFR will be handled by an automated operating mode designed specifically for the UK frequency response service, and is part of the AEROS® controls system, NEC’s proprietary energy storage control software.

Justin Thesiger, Operations Director at Low Carbon, said: “The two new battery parks at Glassenbury and Cleator will ensure stability within the local grid and that the electricity demands of residents can be consistently met, including at times of high demand. Sites such as these are fundamental to our energy security and also to realizing the full potential of renewable electricity generation that hit record levels earlier this year.”
