Fluence to deliver 60 MW battery capacity to UK Power Reserve


UK Power Reserve is partnering with Fluence to deliver the first 60 MW phase of a 120 MW battery storage portfolio. The portfolio was secured through the capacity market auctions in 2016 at a price of £22.50 per kW/h (US$30), Catherine Hunter, spokeswoman for Fluence told pv magazine. Whether the remainder of the 120 MW is going to be delivered by Fluence is yet unlear.

The 60 MW currently under development will be distributed across three 20 MW sites located in the Midlands and North West, and serve regional grids. Fluence says it will use its Advancion energy storage technology platform to meet the ancillary grid service needs.

The three sites are expected to be fully operational by winter 2018/19, according to the companies. As a stand alone system, the batteries are not coupled with renewable energy assets, though using the batteries' functions, Fluence says it will be easier to integrate variable renewable energy assets into the grid.
