Gore Street Energy Storage Fund PLC (LON:GSF) has switched on, or energised its Drumkee project, which at 50Mw installed capacity is the largest in Northern Ireland.
A second 50Mw project in Northern Ireland, Mullavilly, is expected to be switched on in December.
Both Drumkee and Mullavilly are scheduled to be commissioned and become fully operational in the first quarter of 2021, which will increase Gore Street's total installed operational portfolio to 210Mw.
In a statement, Alex O'Cinneide, CEO of the trust’s manager Gore Street Capital, said: "We are delighted to announce the energisation of Drumkee, the largest energy storage asset on the national electricity grid, an important milestone for local climate change goals.
“Both this asset and Mullavilly which remains anticipated to be energised in December will benefit from highly attractive DS3 contracts and from a high return profile."
Gore Street partnered with Low Carbon to jointly own and operate the two projects.
Roy Bedlow, chief executive and founder of Low Carbon added: "This landmark project will increase Northern Ireland's battery storage network by 50MW and forms part of Low Carbon's pledge to deliver renewable energy at scale. “
