Flexitricity has signed a new optimisation partnership with Gore Street Capital, extending the existing partnership between the two.

This agreement covers an initial 155MW of battery energy storage systems (BESS) spread across six sites.

The BESS assets are to be monitored and dynamically optimised from Flexitricity’s 24/7 control room in Edinburgh, operating across multiple markets including frequency response, wholesale traded power, the balancing mechanism and emerging flexibility services.

Gore Street recently outlined how it believes the optimal revenue mix for battery storage is made up predominantly of grid balancing services, announcing it would continue to target minimising capex by designing assets well suited to providing grid balancing services such as Dynamic Containment and Firm Frequency Response.

Last month, Gore Street Energy Storage Fund - managed by Gore Street Capital - raised gross proceeds of £150 million from an initial issue to pursue its 1.3GW pipeline.

Andy Lowe, CEO at Flexitricity, said: “The markets and services which energy storage can uniquely serve are going through significant and necessary change. We see great opportunities ahead for these flexible assets and the contribution they make to supporting the UK grid and enabling the increased build-out of carbon free renewables to deliver on the UK’s net zero ambition.”

Flexitricity’s contracted flexible asset portfolio is now over 800MW, with this including 14 battery storage sites totalling 320MW.

In 2021, it signed an agreement with Foresight to optimise the 49.9MW West Gourdie BESS, as well as teaming up with Kaluza to enable domestic half-hourly settled customers to use their smart chargers, vehicle-to-grid chargers and batteries in the balancing mechanism.
