Island Green Power has secured planning consent for a 500MW battery energy storage system in Aberdeenshire, Scotland. The Abbotshaugh Energy Storage project, roughly 5km west of New Deer, was approved by Scottish Ministers this week, adding another large-scale BESS to Scotland's fast-growing storage pipeline.

Island Green Power is a renewable energy developer wholly owned by Macquarie Asset Management, which took full control of the business in May 2025 after buying the 50% stake it did not already own. Macquarie Group, the ASX-listed financial services group, reported net profit of A$3.71 billion ($2.37 billion, €2.05 billion) for the year to March 2025, with A$941 billion in assets under management.

The structural driver is Scotland's push to firm up a rapidly expanding renewables base with grid-scale storage capacity, reinforced by new planning guidance introduced to help applicants navigate BESS consent earlier in development. The roughly nine-hectare Abbotshaugh site will include landscaping and biodiversity measures and is intended to support grid resilience and energy security.

Nick Bowen, project development manager at Island Green Power, said the company was "grateful to everyone who engaged with the proposals and provided feedback throughout the development process," adding that it would "continue working closely with the local community and our project partners as we progress towards the next stage."

The approval extends a run of Scottish BESS activity this year. Matrix Renewables secured £245 million in construction financing for a 1,000MWh project in southern Scotland, French energy major Engie began commercial operations at two BESS sites at Cathkin and Broxburn, and Enertis Applus+ carried out engineering and procurement work on the 500MW, four-hour duration Wallace BESS in Ayr.

For the sector, Abbotshaugh shows platform investors like Macquarie continuing to back Scottish storage development even as parts of its wider European renewables portfolio, including Cero Generation, have been sold to other investors, underscoring how storage assets are increasingly ring-fenced as a distinct investment thesis.
