NEC Commissions 5.7MWh of Grid Energy Storage Installations in the UK

NEC Energy Solutions has completed commissioning six new Grid Storage Solution (GSS) sites for Northern Powergrid. In total, the systems have nearly 2.9 MW of power and 5.7 MWh of energy storage capacity.

They were installed 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. funded in part through the Office of the Gas and Electricity Markets’ (Ofgem) Low Carbon Networks Fund.

The largest, a 2.5MW, 5MWh GSS™ in Darlington , is located in an urban industrial area, while one of the smallest, a 50kW GSS™, is located in a residential area in Wooler, a small town in the northern part of England.

"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. “We needed battery systems that could fit into a range of electricity distribution substations, so it was important to have a very flexible battery design to accommodate our
very different locations.”

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 UK’s electricity network, as well as supporting other low - carbon technologies.

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.
