Clearly quite a bit of job creation was involved with the government doing their oil and gas and most of their power generation.

Maybe that's it. Looks like another 500MW came on line which is about right. It's an interesting consequence of privatisation that, where once planned nuclear outages were always in the summer, they are now as often as not in the winter. Presumably a consequence of clever players optimising the various markets. I won't use the loaded word "gaming". |

As it is Sunday I assume that the demand is less than during the week. Let us see what tomorrow brings! As I said, something of a warning. Simple arithmetic suggests that if we had 10 times the current infrastructure for solar and wind based generation that would meet only 40% of current demand. During the day.

Norway pumped storage, was Gridwatch and power generation today

I'm confused, is there a browser problem? What I see is a 2017 article saying that, of their 82 TWh pumped storage capacity, they already used virtually all of it themselves. To service Germany they would need to build *lots* more, which they don't want to do, and they would need a huge investment in grid infrastructure to do it. The article is saying that it's *not* a practical solution, which is what you were saying too. If you have enough hydro water you dont necessarily need to pump it. You simply hold it and run your country off imported renewabubbles and unicorn farts.

This announcement emphasized four main goals, which were improving security in the supply of their power, improving the efficiency of their renewables, making their energy more efficiency and environmentally and climate sensitive, and fostering economic development and value through fiscally responsible and renewable technology.[7] The annual electricity consumption was about 26-27 MWh per inhabitant during 2004-2009 when the European union (EU15) average in 2008 was 7.4 MWh.

If supply was short enough on Wednesday night (wholesale prices weren't high for the month, so was it really?) to run OCGT, then wouldn't hydro have cashed-in too? |
