Greenburn Hydro Project

Industrial heritage

From Stone Age axe factory to Victorian gunpowder works, the Langdale valleys have a rich industrial heritage, energised by water power as far back as the 15th century. The Greenburn valley is no exception. As a former copper mine, many features associated with its legacy are still in evidence and of much interest today. The remains of water sluices, leat systems and a waterwheel pit remain visible and the site is now a designated Scheduled Ancient Monument (SAM). 

Green future

This summer we are starting work on a significant hydropower project nestled in the heart of this valley. When complete it will provide a robust renewable energy solution in a landscape where few other opportunities exist to bring in a guaranteed income 'stream' to support our future conservation work in Little Langdale.

Keep checking back below for regular updates from the project team on how the work is progressing and more about the unique history of this valley. We're looking forward to sharing this exciting project with you as each stage unfolds.

Join us on Heritage Open Day

If you’re interested in learning more about the Greenburn hydro scheme, we’re running a free and exclusive guided walk next month on Thursday 13 September. Join our project team as we make our way through the stunning Little Langdale valley, passing physical reminders of its industrial heritage along the way. You’ll learn about slate mining at Tilberthwaite, copper mining at Greenburn, and we’ll finish up with a visit to the newly installed hydro scheme.

All quiet on the hydro front

If it feels as if our hydro updates have slowed, that’s because we’re nearing completion of the project and there is less happening across the site. The powerhouse is now complete, clad in stone from the quarries around Tilberthwaite so that it blends into the valley landscape. The track up to the intake has been re-landscaped and we will re-seed when it next rains. All that remains is to connect the hydro into the national grid and that will happen in the next month once the surrounding fields have been mown. Then all we need is some rain!

The turbine has arrived

A major milestone has been achieved with the delivery of the turbine to the powerhouse. The equipment left the factory in Kendal and arrived early to avoid any traffic on the narrow roads around Little Langdale. The turbine is a 100kW Gilkes Pelton turbine.
