London, March 31, 2026, 15:27 (BST).
Rolls-Royce Holdings on Tuesday said it’s kicked off construction on a 43-megawatt battery storage site in Falkirk, Scotland. This marks the UK engineering firm’s first major battery project at scale in the country, a step deeper into grid-related business. The facility, being developed for Voltaria Helios Energy Storage, is slated to provide 43 megawatts of output with 86 megawatt hours of capacity. Grid hookup is targeted for 2026, and commercial operations are set to follow in 2027.
Britain’s push for more batteries comes at a crucial moment, with the country aiming to store excess wind and solar output and deploy it during demand surges. The Clean Power 2030 strategy targets 23-27 gigawatts of battery storage before the decade wraps up. Rolls-Royce, for its part, pointed to rapid data-centre growth as a tailwind for its power systems arm, and reported a 40% jump in underlying operating profit for 2025 back in February.
Rolls-Royce takes on the full build—engineering, procurement, and construction—plus a 15-year maintenance stretch at the site. Voltaria CEO Nigel Jefferson described Bankside as just the beginning, the first in a series of battery sites the company aims to launch. Andreas Görtz at Rolls-Royce Power Systems pointed to experience from over 200 battery projects globally.
Rolls-Royce has been making headway financially, and that momentum is now carrying into Scotland. Back in February, the company laid out plans for a hefty £7 billion-£9 billion buyback between 2026 and 2028, according to results at the time. Chief Executive Tufan Erginbilgic described the ongoing transformation as moving “with pace and intensity”. Rolls-Royce
Rolls-Royce continues to hand back cash to investors as it scales up. On March 30, the company repurchased 1,198,568 shares, according to a filing released Tuesday. That brings buybacks under its £2.3 billion programme, launched in February, to a total of 27.7 million shares so far.
Rolls-Royce isn’t the only company targeting the UK’s battery ramp-up. Back in January, Drax locked in a 10-year deal linked to a 250-megawatt battery project in England. Finland’s Wärtsilä, meanwhile, is growing a UK battery portfolio with EDF Renewables, bringing their total to 404.5 megawatts.
Jacopo Tosoni, deputy secretary general at Energy Storage Europe, called the UK one of Europe’s battery “investment hotspots” in a conversation with Reuters Events last month, citing “strong market fundamentals” and “supportive policy frameworks.” No surprise, then, that industrial suppliers are piling in.

The expansion hasn’t been smooth. Reuters Events points to limited grid capacity across Europe that’s still putting the brakes on new projects. China continues to lead battery manufacturing, leaving developers vulnerable as demand keeps climbing with the push for renewables, more electrification, and calls for steadier power.
