Global grid-connected market opens up for flow battery firm RedT

Published on: November 23, 2017 5:27 amBy: Jade Beevor


Vanadium flow battery developer RedT Energy was named as the first official participant in utility company Centrica’s local energy market trial, in which £19 million ($25million) has been allocated to test how flexible power generation and storage can reduce pressure on the UK’s local grid systems.

Centrica will take control of the system’s operation and begin trading energy after the 1MWh machines —  RedT does not consider them batteries — were officially connected to the grid on November 13.

The machines will store energy generated by solar panels at a 600-acre farm, the Olde House, in north Cornwall in the south of England, in the batteries to provide overnight power — with estimated savings of 50% on grid imports during peak periods.

Centrica’s project was launched in December 2016 with Western Power Distribution, the University of Exeter and the National Grid and funded by Centrica, the British Gas Energy for Tomorrow fund and a grant from the European Regional Development Fund.

It is part of a shift away from large power stations to smaller, more distributed providers, making it possible for users to trade any excess generation with other consumers, said Joe Worthington, a RedT spokesperson.

“In addition to traditional contracted grid services such as frequency response, merchant revenue services like this will play an important part of our future energy system.”

On November 16 RedT announced its first sales in Asia, with the completion of a deal to supply nine commercial energy storage systems to be used as flexible platform assets, connected to the local grid and performing a range of services.

The sale consists of four 30kW-150kWh energy storage machines in addition to a single 5kW-20kWh battery.

This follows an announcement on September 25 that 14 of RedT’s 40kWh modules had been sold to a Botswana-based customer for remote communications infrastructure sites across the country.

All the sites will use 11kWp of solar panels per site as the sole form of power generation.
