UK’s Historic Hydro Stations Could Host Solar Panels in Renewable Energy Push

Several of the UK’s historic hydroelectric power stations may soon be outfitted with solar panels as part of a broader plan to increase renewable energy output. The proposal, led by energy company Drax Group, combines traditional hydroelectric generation with modern solar technology, creating hybrid sites that can deliver more consistent and diversified green energy to the grid.

Drax owns and operates the Lanark and Galloway hydro schemes in Scotland, which have been producing renewable electricity for over 90 years. Under the new plan, these existing facilities could be retrofitted with solar panels on adjacent land or structures without disrupting the flow of hydroelectric production. The initiative is designed to make full use of available space and optimize power generation throughout the year.

The company is currently consulting with local communities and heritage bodies to ensure the project respects the sites’ historical and environmental significance. The Lanark and Galloway schemes are classified as listed structures, meaning any changes must meet strict planning and conservation standards. Drax has emphasized that the integrity and visual character of the historic stations will be preserved.

If approved, the hybrid model could serve as a blueprint for enhancing legacy energy infrastructure nationwide. Hydropower typically performs best during wetter months, while solar panels are more effective during sunnier periods. Drax aims to provide more stable year-round power output by combining the two technologies, supporting the UK’s transition to a net-zero carbon economy.

The proposal is part of Drax’s broader effort to increase its renewable energy capacity. The company, which also operates biomass power plants, has committed to expanding its portfolio of clean energy sources while phasing out fossil fuels. The potential integration of solar at hydro sites reflects a growing industry trend of reimagining existing energy assets to meet modern sustainability goals.

Environmental groups and local stakeholders have cautiously welcomed the idea, noting the importance of minimizing environmental impact while maximizing clean energy output. Planning applications are expected to be submitted later this year, following the conclusion of public consultations.

This project highlights the evolving nature of the UK’s energy landscape, where historic infrastructure is being adapted for future demands. The move could inspire similar upgrades at heritage energy sites nationwide, offering a practical path toward energy resilience and climate responsibility.
