NEC Energy Solutions has commissioned six new Grid Storage Solution (GSS) sites for Northern Powergrid in the U.K. In total, the systems have nearly 2.9 MW of power and 5.7 MWh of energy storage capacity.
The GSS sites are in substations in both urban and rural locations as part of the Customer-Led Network Revolution (CLNR), a three-year smart grid project in the U.K. Energy storage is a key component of the CLNR smart grid project and will be used to help integrate more solar and wind energy into the U.K. electricity network, as well as supporting other renewable energy technologies.
‘Part of the challenge of installing energy storage in these areas was the wide diversity in the various sites,’ says Ian Lloyd, CLNR technology manager at Northern Powergrid.
NEC Energy Solutions supplied lithium-ion-based grid battery systems for the project, packaged in a variety of enclosures, including standard 40-foot containers and smaller customized enclosures. The largest site, a 2.5 MW/5 MWh GSS in Darlington, is located in an urban industrial area. One of the smallest sites is a 50 kW GSS in a residential area in Wooler, a small town in northern England.
In May, NEC Corp. acquired A123 Energy Solutions, the grid energy storage business of A123 Systems.
