The installed capacity of the UK’s large-scale battery storage projects has broken through the 100MW landmark, according to new figures.

Solar Media’s UK Battery Storage Project Database now lists around 50 battery storage sites with individual capacities above 250kW.

Nearly 60% of the capacity added during 2017 has been co-located with renewable or non-renewable power sources.

The report highlighted the large number of batteries now being connected to solar farms.

Importance of capacity market

Solar Media said: “The pre-qualification window for the 2018 capacity market recently closed and there are projects that have already made known their intention to participate.

“The upward trend in planning applications over the summer also suggests that this year’s capacity market will be hotly contested.

“It appears that the relative stability and longer-term contracts of the capacity market are highly important in making the business cases stack up for new battery storage projects.”
