Glen Earrach Energy (GEE) has submitted its application for a 2-gigawatt (GW) pumped storage hydro (PSH) project on the Balmacaan Estate near Loch Ness, a development that promises significant energy storage capacity and community benefits if approved.
The proposed project, which aims to become one of the UK’s largest and most efficient PSH facilities, could provide more than £20 million annually for Highland communities over its 125-year lifecycle through a dedicated community benefit fund.
“We’ve listened carefully to local views and will keep doing so,” said Roderick Macleod, Director at GEE. “Now we look forward to working with the Scottish Government, The Highland Council and all key stakeholders to deliver this vital project.”
The project’s design takes advantage of the site’s unique topography, including a 500-meter hydraulic head, which will allow it to generate and store more energy than all other planned Loch Ness projects combined. GEE’s proposed 2GW capacity is equivalent to the output of approximately 800 onshore wind turbines in the region.
New polling conducted by Opinium and commissioned by GEE indicates strong support for the PSH project, with 56% of Highland residents in favor. However, the polling also reveals that local residents want the Scottish planning system to prioritize projects with the greatest impact.
The project aims to stabilize the UK’s energy grid by storing surplus renewable energy and reducing the need for curtailment payments. During peak construction, it is expected to support around 1,000 jobs and create long-term employment opportunities, benefiting the local and regional supply chain.
GEE has prioritized community engagement, holding four rounds of consultations with local communities before meeting statutory pre-application requirements. These consultations have led to significant design adjustments to reduce visual impact, minimize infrastructure, and protect scenic views, particularly along the A82 transport route.
The 2GW PSH project, if approved, would be the largest of its kind in the region, contributing to the UK’s renewable energy capacity and supporting long-term sustainability goals. GEE anticipates that power generation will begin in 2030, marking a milestone in both energy storage and community investment for the Highlands.
