The proposed facility aims to support the UK’s net zero goals by enhancing energy reliability and reducing costs. GEE estimates the project will contribute £20 million annually to Highland communities over its 125-year lifespan through Scotland’s largest community benefit fund. The project is expected to provide around 1,000 jobs during construction and sustain long-term employment opportunities in the region.
A recent Opinium poll, commissioned by GEE, indicates 56% of Highland residents support pumped storage development at Loch Ness, with 16% opposed. The survey highlighted local priorities, including reliable and affordable energy (54%), cost-effectiveness (53%), and economic and job benefits (53%). Only 7% of respondents felt project approval should be based on submission order.
GEE’s project is designed to deliver 34GWh of energy storage, representing nearly three-quarters of the planned capacity for Loch Ness, while using half the water volume. The site’s 500m elevation drop and natural topography enhance its efficiency. The company projects a 10% reduction in the UK grid’s carbon emissions and £2.9 billion in system benefits over the first 20 years.
Following community input, GEE adjusted the project to minimize visual impact, reduce A82 road transport, and limit above-ground infrastructure. The company conducted four rounds of public consultations before the formal pre-application phase and pledges ongoing engagement with local stakeholders during the planning process. A Letter of Intent confirms GEE’s commitment to a multi-million-pound community benefit fund.
Roderick Macleod, Director of Glen Earrach Energy, said: “This project is poised to become one of the UK’s largest and most advanced energy storage initiatives, delivering the most substantial community benefit fund ever in Scotland. The Highlands deserves the best project, and we remain on track to deliver it, with the first power being produced in 2030.”
Richard Whitehead, AECOM Chief Executive for Europe and India, added: “As the UK transitions to cleaner energy, pumped storage hydro will play an increasingly important role in its future energy mix, providing reliable and efficient storage solutions to balance the grid. The scale of Glen Earrach has the potential to meaningfully contribute to Scotland’s net zero ambitions, and those of the UK as a whole, while also delivering benefits to both the environment and local communities.”
The project awaits review by the Scottish Government and The Highland Council, with GEE committed to collaboration to advance this significant energy initiative.
