redT to install 1 MWh of energy storage at Cornwall site

redT energy plc (LON:RED) today said it will place six energy storage units, totaling 1.08 MWh, at a working farm and holiday retreat in Cornwall, England.

The machines, based on vanadium redox flow technology, were originally intended for the Isle of Gigha as part of a project to remove capacity constraints on the island's community wind farm. The issue has been dealt with thanks to an upgrade of the grid connection to the mainland and a decision has been taken to move the energy storage capacity to a site "where the systems can be better utilised to maximise their full range of functionality".

Six storage units will now be installed at The Olde House. They will be coupled with 350 kWp of grid-connected solar arrays. In addition to timeshifting solar electricity, the energy storage capacity will demonstrate functionality to provide energy services to the local Cornwall grid, which can include a combination of frequency response, STOR, participation in the capacity market and demand turn up, redT said. Further functionality such as participating in energy arbitrage and local energy trading is proposed to be demonstrated over time, it added.

The Isle of Gigha project involved the UK government, which will continue the support the machines at the new site. The batteries will be owned by redT. One remaining battery unit manufactured for the island will also be placed at a new site in due course, according to the announcement.
