BESS developer-operator Field has put a 2-hour BESS into commercial operation north of the heavily-constrained B4 transmission boundary in Scotland. The Auchteraw battery energy storage system (BESS) near Fort Augustus is the fourth and largest for Field, which announced its completion this week (20 August), and its first in Scotland. The project will provide flexibility services to the grid and address ‘significant constraint costs’ in the region, it said. Amit Gudka, CEO of Field, said: “Bringing Auchteraw online is a major milestone for Field as our largest site yet and first in Scotland. August has been a busy month for large-scale BESS project completions in the UK.
