UK has some tariffs with a cheaper electric charge at night called Economy 7. This is used to heat storage heaters for properties without gas central heating.

Industrial load will also play a factor, as will lighting homes during the dark hours.
- NeedMoreTea 8y agoThe biggest industrial users - those on half hourly metering - also get discounts to move usage offpeak, and there's some tariff options that turn off or restrict those highest users during peaks. Partly so the grid don't have to keep waking up Dinorwig. :)
- ljf 8y agoTo save others googling: https://en.wikipedia.org/wiki/Dinorwig_Power_Station https://en.wikipedia.org/wiki/Dinorwig_Power_Station - cheers for the interesting read!
- semi-extrinsic 8y agoWow. When notified in advance, Dinorwig can go from 0MW to 1800 MW power delivery in 16 seconds. Unprepared, looks like it takes a couple of minutes.
- 24gttghh 8y agoSeems puny compared to the twin plants on the Niagara in the USA/Canada (both are pumped-storage hydro): 2,675 MW: https://en.wikipedia.org/wiki/Robert_Moses_Niagara_Power_Plant https://en.wikipedia.org/wiki/Robert_Moses_Niagara_Power_Pla... 1,997 MW: https://en.wikipedia.org/wiki/Sir_Adam_Beck_Hydroelectric_Generating_Stations https://en.wikipedia.org/wiki/Sir_Adam_Beck_Hydroelectric_Ge...
- poooogles 8y agoYou're comparing apples to oranges. They're not pumped storage stations.
- 24gttghh 8y agoTechnically, they're actually both: "Water enters the forebay via tunnels from the Niagara River controlled via the International Control Dam upstream of the natural falls. Water in the forebay is then either pumped up into the upper reservoir or immediately sent down over the escarpment downstream of the natural falls into the Robert Moses Power Station turbines." So, it's like more like Malus pumila (Domestic Apple) to Malus sieversii (Wild Apple).
