One of the largest operational battery storage assets in Scotland has been successfully brought online by SUSI-Eelpower – a joint venture between SUSI Partners and sustainable power infrastructure firm, Eelpower.

The Dundee-based facility is the latest addition to SUSI’s UK battery storage portfolio, which it began in 2017 and finalised in 2021.

Their portfolio consists of seven utility-scale battery sites distributed across England, Scotland, and Northern Ireland, of which five assets combining for 140 MW are now operational, with two further 50 MW batteries expected to be brought online later this year.


The UK relies heavily on battery storage facilities to enable the increased integration of intermittent renewable energy into its electricity mix. The UK has long been a global leader in installed offshore wind capacity – today only outranked by China.

With its energy storage fund, SUSI was one of the earliest investment managers directing institutional capital towards battery storage technology, forming a diversified portfolio of both utility-scale and behind-the-meter solutions with investments across Canada, the UK, Australia, and the United States.
