First hydropower projects in Great Britain in 40 years given go-ahead
The UK's energy regulator has given the go-ahead for 16 long-duration electricity storage projects, including three pumped storage hydroelectric power stations in Scotland. This marks the first new hydropower projects in over 40 years.

The projects aim to reduce Great Britain's reliance on energy imports and balance the supply and demand of electricity, which can fluctuate due to the unpredictability of renewable energy sources.
The UK is building new hydropower projects to store energy for later use, helping to keep the lights on when the sun isn't shining or the wind isn't blowing.
Analysis
Introduction to Hydropower Revival
The UK's energy regulator, Ofgem, has provisionally agreed to allow the construction of 16 long-duration electricity storage projects, including three pumped storage hydroelectric power stations in Scotland. This decision marks a significant milestone in the country's efforts to reduce its reliance on energy imports and transition to a cleaner power system.
The three pumped storage hydroelectric power stations, located in Northern Scotland, will be the first new facilities to be built since the Dinorwig hydropower plant in north Wales in 1984. The projects, which include SSE's Coire Glas at Loch Lochy and Gilkes Energy's Earba, will have the capacity to store and release electricity for periods of eight hours or more.
Benefits of Long-Duration Energy Storage
The development of long-duration energy storage projects is essential for balancing the supply and demand of electricity, which can fluctuate due to the unpredictability of renewable energy sources such as wind and solar power. The 16 projects given the provisional green light will help to ensure a stable and secure energy supply, reducing the risk of power outages and price shocks.
According to Akshay Kaul, the director general for infrastructure at Ofgem, the development of these projects takes the UK a step closer towards achieving a clean power system. The use of long-duration energy storage technologies, including compressed air, lithium-ion batteries, and vanadium redox flow batteries, will help to maintain a secure supply of electricity during periods of cold, hot, still, or cloudy weather when solar or wind power output may be low.
Implications for the UK's Energy Security
The construction of these projects has significant implications for the UK's energy security and its efforts to reduce its reliance on global gas markets. The energy minister, Michael Shanks, stated that the lesson from the conflict in Iran is clear: Britain cannot afford to remain at the mercy of volatile fossil fuel markets and leave families exposed to the next price shock.
The development of these projects is a crucial step towards achieving the UK's goal of reducing its carbon emissions and transitioning to a cleaner power system. The use of long-duration energy storage technologies will help to ensure a stable and secure energy supply, reducing the risk of power outages and price shocks, and providing a cleaner and more sustainable alternative to fossil fuels.
Key points
- 16 long-duration electricity storage projects given provisional go-ahead
- Three pumped storage hydroelectric power stations to be built in Scotland
- Projects aim to reduce UK's reliance on energy imports and balance supply and demand of electricity
The development of these projects could lead to a significant reduction in the UK's reliance on energy imports, improving the country's energy security and reducing its carbon emissions. The use of long-duration energy storage technologies could also provide a cleaner and more sustainable alternative to fossil fuels, helping to achieve the UK's goal of transitioning to a clean power system.
The construction of these projects may face delays or setbacks, potentially impacting the UK's ability to achieve its energy security and carbon emission reduction goals. Additionally, the high upfront costs of developing long-duration energy storage projects may be a barrier to their widespread adoption.
