Two grid-scale projects totalling 50MW of new energy storage capacity have been connected to the grid in the UK.
The US-European partners behind the lithium-ion projects said the commissioning represented the “largest portfolio of utility-scale battery energy storage systems connected to the UK grid”.
NEC Energy Solutions and VLC Energy, a joint venture between renewables investment firm Low Carbon and VPI Immingham— part of the Swiss-based Vitol energy trading and distribution group— said on 8 January that their 40MW facility in Glassenbury in Kent and a 10MW installation in Cleator, Cumbria (pictured) were operational.
NEC Energy Solutions, a subsidiary of Japanese multinational the NEC Corporation, provided turnkey engineering, procurement and construction services for the projects including its GSS end-to-end grid storage solution.
The partners confirmed previously that both sites had signed contracts with National Grid, the UK system operator, to provide enhanced frequency response.
