Zenobē has commenced construction on its 400MW/800MWh battery storage project in Eccles, Scotland, aiming to enhance grid stability and maximize the use of renewable energy.
Key Project Components:
Tesla will supply its Megapack 2 XL energy storage system, enabling remote monitoring, operation, and diagnostics. This marks the UK’s first project utilizing Tesla’s grid-forming technology, already deployed in the US and Australia.
OCU Group, as the principal designer, is responsible for electrical and civil works and constructing the balance of plant.
Hyosung Heavy Industries will provide super grid transformers, connecting the battery system to the transmission network.
Stability & Energy SavingsThrough a dedicated contract, the Eccles site will supply Stability Services to the National Energy System Operator (NESO), improving the reliability and affordability of the UK’s renewable power system. This marks Zenobē’s third such contract, delivering 2,984MWs of inertia—nearly 40% of the inertia awarded in the 2022 Stability Pathfinder 2 tender—alongside 936MVA of short circuit level.
The project will ensure wind and solar power are fully utilized, preventing waste. Once operational, it is expected to save UK consumers £309 million over 15 years and avoid 4.9 million tonnes of CO₂ emissions by better integrating wind power into the grid.
