London-listed RedT Energy plc will install a power storage system at a 1MW wind farm on the Scottish Isle of Gigha.

The company has delivered the first two of the seven 15kW-240kWh battery units to the University of Strathclyde’s Power Networks Demonstration Centre in Cumbernauld, where they will be tested before being installed.

The 1.68MW vanadium flow system was chosen for this remote location, which has limited grid connection, due to their ability to balance variable generation from renewables, the company said

It will remove existing constraints on wind generation capacity, it added.

The Gigha energy storage system is funded by DECC and RedT along with project partners including SSE, EA Technology, Community Energy Scotland and Gigha Green Power.

"The delivery of contract manufactured, large-scale containerised vanadium flow batteries to a customer's project for the first time is a huge achievement for us and for the industry as a whole,” RedT chief executive Scott McGregor said.

“"We are making consistent progress towards the full commercialisation of our units and this news serves to underline the leading role we are playing in delivering a viable, modular solution to the energy storage market."
