Bess Developer-Operator Field has brought a 2-hour Bess in commercial operation north of the heavily limited B4 transmission boundary in Scotland.
The Aucheraw Battery Energy Storage System (Bess) near Fort Augustus is the fourth and largest for Field, announcing this week (August 20) and his first in Scotland.
The project will offer flexibility services to the schedule and tackle ‘significant limitation costs’ in the region, said it.
Thanks to the location north of the B4 transmission limit over the Scottish central belt. There are huge amounts of wind energy north of the border, most of which have to go to requirements in the south.
The total restriction costs in Great Britain (GB) were £ 1.7 billion and almost £ 1 billion in the first half of 2025, says the National Grid of the Transmission System (TSO). More than 10%, £ 117 million, of the H1 2025 figure was in Noord -Schotland.
These costs are expected to rise considerably in the coming years, but large-scale Bess can help to reduce them by offering balance services to National Grid through the Balancing Mechanism (BM).
It follows the Laancing construction field on two other, identical size projects in Scotland recently, the Holmston and Drum Fard projects. Lithium-ion oem en vision will be the bess for that. Field also recently received a planning approval for a 200MW project in Suffolk, England, called Yaxley.
Construction and engineering works for the Aucheraw project were provided by RJ MCLEOD, now owned by OCU Group respectively.
Amit Gudka, CEO of Field, said: “Taking AuchteraW online is an important milestone for the field as our largest site so far and first in Scotland. This will make a real difference for invoice payers by reducing the costs of the restriction and ensuring that the valuable renewable energy of Scotland can be used.”

Augustus has been a busy month for large-scale BESS projects in the UK. This week we also reported on Statera Energy Placing the largest operational project of the UK online at 300 MW/600MWHwhile earlier in the month Eku Energy has ordered two locations of a total of 130 MWh of capacity.
