studiot Posted October 29, 2022 Share Posted October 29, 2022 https://www.bbc.co.uk/news/uk-scotland-63402811 Quote Hydroelectric schemes are not unusual in Scotland, where lochs and reservoirs currently provide enough water to power around half the nation's homes, according to the Scottish Environment Protection Agency. Knoydart, though, is different - so remote that it is not connected to the National Grid, meaning prices here are not dictated by the wholesale cost of more expensive forms of energy such as gas. Just look how low this dam is. Link to comment Share on other sites More sharing options...

Quote Currently, around 5000GWh (Gigawatt hours) of electricity from hydropower are produced every year; that’s enough to power roughly half of Scotland’s homes. ... Are you pointing to how they're able to do so much with a small dam? Quote However, if not constructed or maintained in accordance with best practice, hydropower can seriously impact on river ecology and fish stocks. In the worst case, rivers could be dried-up completely for hundreds of metres downstream. So, striking the right balance between protecting the water environment and renewable energy generation is vital. Or are you saying the water flow past the dam is low? Resevoir looks topped off. Reading a while it occured to me to construct an inlet off from the ocean, allowing water to move inland and downhill to run a turbine and have it go to groundwater or form a small delta. Probably engineering contingencies I'm not taking into account. Please elaborate on what it is you're trying to continue to bang on about. Link to comment Share on other sites More sharing options...

Surely the relevant question is how high this lake or tarn is above the generating station, i.e. the head available for power generation. In the Highlands, one of the things that is free is height.

StringJunky Posted November 1, 2022 Share Posted November 1, 2022 How much habitat was flooded to make it? Link to comment Share on other sites More sharing options...
Sensei Posted November 1, 2022 Share Posted November 1, 2022 (edited) 129 L per second flow * g * height = max power you can get from it. This does not look impressive. In rural uninhabited wasteland - acceptable. However, they would get more from solar panels on the roof. Edited November 1, 2022 by Sensei Link to comment Share on other sites More sharing options...
