Derwent Hydro provided procurement, supply, installation and commissioning services for the Ynni Ogwen Hydro Scheme, which began generating in 2017.
Located near Bangor, North Wales, this community owned hydropower installation produces a peak output of 100kW, passing 800lps on 18m head.
Since commissioning, this site has frequently exceeded energy capture expectations. Averaging almost 500MWh annually, Ynni Ogwen Hydro has the capacity to power 185 average-sized local homes; saving 250 tonnes of CO2 when compared to gas-fired electricity generation. The associated revenues also provide a range of benefits to the local community, including the funding of solar panels on community buildings.
Ynni Ogwen Hydro uses an Ossberger twin vane Crossflow turbine. Water is abstracted from the Afon Ogwen through an over-wash intake screen and conveyed to the turbine via a buried pipeline.
The turbine is operated using a DHPL control panel, boasting remote functionality and web-based data logging facilities. This allows us to efficiently support the operator from our base in Derbyshire.
DHPL also has a maintenance base in Wales. We employ a full-time North Wales based technician, supported by our wider multidisciplinary team. This allows us to provide cost-effective regular servicing as well as turnkey fault diagnostic and resolution activities.
Gareth Cemlyn Jones, Ynni Ogwen chairman, commented that the equipment supplied by DHPL has ‘proved to be well specified, robust and reliable with no significant operational issues since commissioning’, adding that ‘any support required from DHPL has been prompt and efficient.’
