Information

Hydro Ogwen is a community hydro-electric generation scheme on the Afon Ogwen owned and operated by Ynni Ogwen Cyf (Ogwen Energy Ltd), a company established in 2015 to complete the development of the project and to manage it thereafter. The venture was financed by £450k raised via a community share offer and profits are to be distributed for the benefit of the local community.

Family-run contractors Gwyn Roberts Construction, based near Bala, carried out the building work, which started in July 2016 and was mostly completed by March 2017. The 100 kW generator, whose estimated annual output will be 500 MWh, is driven by a turbine fed via a 900 mm diameter pipe buried under the Lon Las Ogwen path with water abstracted from the intake weir, approximately 300 m upstream, just above the waterfalls at Ogwen Bank.

  1. Nice to see the appropriate use of Hydro Power, to benefit the community in a discrete and sustainable way that doesn’t ransack the landscape in the process. Lovely photos, as we have come to expect from you, Graham 🙂
