The potential impacts of climate change on hydropower generation in Mid Wales

Hydropower is a potential large source of electricity supply in Wales. The Upper River Severn in Mid Wales is a typical stream where a high head hydropower scheme could be developed and the river system at Plynlimon has some of the longest records for weather and flow in Wales. A micro-hydropower potential of 99 kW is demonstrated at Plynlimon and the potential impacts of climate change are ...

Double Flanged Sleeve Valves

They allow a very high upstream pressure loss, without any risk of critical phenomena (cavitation, vibration, noise) even with little downstream head pressure. They are also used as synchronous discharge tool for turbine plants (mainly Pelton or Francis turbines) because they are able to work in high pressure condition. The discharge is carried out under high head loss across of the valve.
