Of the 64 successful projects, 61 involve battery assets, according to the UK’s electricity system operator. Two demand reduction projects and single thermal generation project were also successful, it said.

Successful projects will be used by National Grid to aid it control the increasing variations in system frequency that can be caused by intermittent renewable power sources feeding into the grid. In order to successfully balance power furnish and demand across the UK, system frequency must be maintained at a steady 50 cycles per second (50Hz), according to National Grid.

Previous technology solutions could react to system frequency volatility in beneath 10 seconds. The projects awarded contracts beneath the EFR tender will be expected to respond in beneath a second, reducing National Grid’s costs by £200 million and ultimately the complete costs of the consumer, the system operator said in its announcement.

The recent projects are expected to be online between October 2017 and March 2018, according to National Grid. Once online, they should be competent to provide 201 megawatts (MW) of EFR, at a total cost of fair beneath £66m.

power expert Peter Feehan of Pinsent Masons, the law firm behind Out-Law.com, welcomed the awards, which he said had the potential to aid the UK to tackle its “very real threat of blackouts”.

“Headline-grabbing furnish crunches and threats of blackouts possess brought the issue of security of furnish into sharp focus,” he said.

“While it is early days, with multitudinous of the projects bidding for a place on this panel unmoving in the early stages of development, the underlying drivers to investing in power storage are clear. Talk of ‘keeping the lights on’ is more than fair punchy rhetoric – it’s a challenge that we must tackle head on. Bolstering our home grown power furnish and harnessing it more effectively will reduce our reliance on pricy imported power, and will lower consumer costs,” he said.

National Grid said that the four-year term of the contract awards would “handover providers the certainty that they require” to develop the technology.

“This project is at the very core of our ‘power responsive’ toil, to balance the grid by the most efficient means possible, saving money and power,” said Cordi O’Hara, a director of National Grid. “These awards demonstrate that we can toil with industry to bring forward recent technology and I believe storage has much to contribute to the flexible power system of tomorrow.”

Speaking to the BBC earlier this week, recent National Grid executive director Nicola Shaw called for a ‘smart’ power “revolution” to aid reduce the risk to the UK of blackouts at times of lofty demand.

Shaw told the BBC that between 30% and 50% of grid fluctuations could be addressed by coordinated demand reduction at top times through the operate of recent software and controls.
