Glen Earrach Energy (GEE) has officially submitted an application for a 2GW pumped storage hydro (PSH) project near Loch Ness in Scotland. The company submitted the application to the Scottish Government as part of the regulatory process under Section 36 of the Electricity Act 1989.
The project, if approved, could become one of the UK’s largest energy storage projects, potentially contributing significantly towards net-zero goals, enhancing energy security, and reducing energy costs.
It is also projected to provide over £20m annually to Highland communities throughout its 125-year lifespan.
According to independent polling conducted by Opinium, commissioned by GEE, there is substantial support among the Highland population for the PSH project, with 56% in favour and 16% opposed. In the survey, residents emphasised the importance of prioritising projects with significant community and energy impact.
GEE’s proposed PSH project would account for nearly 75% of the total PSH storage planned for Loch Ness, utilising 34GWh out of 46GWh, and two-thirds of the generating capacity while using only half the water. The site’s topography, featuring a 500m hydraulic head, allows for an efficient design, enabling more power generation and energy storage than all other projects combined in the area.
The 2GW capacity of the project is comparable to the output of approximately 800 onshore wind turbines currently operational in The Highland Council area. It aims to stabilise the UK grid by storing excess renewable energy, reducing curtailment payments, and contributing to a 10% reduction in the grid’s carbon footprint. Additionally, it is expected to deliver a £2.9bn Net Present Value in grid Net Systems Benefit over its first 20 years.
GEE has engaged in early and extensive community consultations since requesting a Scoping Opinion in April 2024. This approach has led to significant design modifications to minimise visual impact, reduce transport along the A82, protect scenic views, and limit above-ground infrastructure.
The Section 36 application includes a comprehensive Environmental Impact Assessment (EIA), developed following detailed site studies by environmental specialists. The project is anticipated to support approximately 1,000 jobs during peak construction.
Glen Earrach Energy director Roderick Macleod 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.
“We’ve listened carefully to local views and will keep doing so. Now we look forward to working with the Scottish Government, The Highland Council and all key stakeholders to deliver this vital project.”
