develop Local Energy Markets, where hydropower’s ability to provide reliable, low-carbon, and dispatchable energy across the distributed network can be properly valued.
Pumped storage hydropower Pumped storage hydropower is increasingly
recognised as essential to balancing a renewable-led grid, reflecting a broader shift in how hydropower’s system value is understood. Following years of petitioning for a price stabilisation mechanism, the UK Government is working towards introducing a cap and floor mechanism for Long Duration Energy Storage. This is a significant breakthrough for the sector, with a wave of large-scale hydropower deployment likely to commence in the next 12 to 18 months. This will be the largest mobilisation of hydropower in nearly 40 years, and the BHA is looking forward to supporting the sector as it delivers this next generation of projects.
Tidal range hydropower Tidal range is on a similar trajectory to pumped
storage hydropower, with a slower but steadily growing recognition of its value to the energy system. Its predictability and long asset life offer clear advantages, particularly in supporting a more flexible, low-carbon grid, though these are not yet fully reflected within current policy frameworks. The BHA, through its role as secretariat to the Tidal Range Alliance, continues to advocate for the sector across government, working to build a clearer understanding of its long-term value. Progress remains incremental but is moving in the right direction.
Alongside its policy work, the BHA continues to act as a convening body for the sector. Its Summer Conference, taking place on the 3rd & 4th of June, will bring together industry stakeholders to discuss current challenges and future opportunities. The Association also maintains a regular programme of engagement through newsletters, consultation responses, and its quarterly magazine spotlight. Looking ahead, the role of organisations such as the BHA will only become more important. As the UK energy system evolves, ensuring that hydropower’s full value, including reliability, flexibility, and longevity, is recognised within market and policy frameworks
will be critical. Hydropower has a clear role to play in the energy system of tomorrow. The challenge now is ensuring the framework around it is fit for delivery.
