China's biggest-ever solar power plant goes live: world's #2 at 2.2 GW! Construction on the project was completed in September after just four months. cnet.com/news/chinas-bi…
2.5 of these would produce as much electricity per year as a 1 GW nuclear power plant running continuously.
But building those solar power plants one after the other would take 10 months instead of 10 years.
Searching a bit more, it looks like the 200 MWh storage took 4 months to complete, but the solar farm itself took 10 months: pv-magazine.com/2020/10/01/wor…
This also states that the plant will deliver power at €0.043/kWh, that's $0.05/kWh.
From end-1997 to end-2003, the world as a whole managed to install 2.2 GW of solar PV, which meant a 6-fold growth of the cumulative capacity at the time.
From November 2019 to September 2020, the construction crew installed 2.2 GW in this one Chinese solar PV power plant.
200 MWh of battery storage on a 2,200 MW solar PV plant is not a lot by the way.: enough to store 5.5 minutes of the plant's full power. It's probably meant to stabilize the short-term output before putting it on the 800 kV ultra-high-voltage transmission line.

Starting a week-long business & pleasure trip to Spain, by train!
Hope to be in Barcelona this evening :)
I'll keep you posted in this🧵
The plan for today: Utrecht - Rotterdam - Paris - Barcelona. The tricky part is changing trains in Paris. Theoretically 2 hours should be more than enough to get from Paris-Nord to Gare de Lyon (the rail planner irresponsibly proposed 1 hour), but @Eurostar is often delayed (2/n)
Made it to Rotterdam, at least ;)
Bit very early, but hey, why hurry on a Saturday morning? (3/n)
Reading the Dutch "Action agenda congestion low-voltage grids".
The accelating energy transition already brings grid issues here. In the low-voltage distribution grid, the growing number of solar panels (PV), electric cars (EV) and (hybrid) heat pumps ((h)WP) is the challenge.
Without measures, a large and growing number of households would experience periods with too high or too low voltage (over- resp. onderspanning) or risk of grid failure.
Measures are categorized in: 1) accelerating grid expansion 2) more efficient use of the grid capacity 3) saving energy as much as possible.
1) already gets a lot of attention, and each of the three main DSOs plans to spend around €1 billion/year. Many hurdles though.
"Transition doesn't make energy cheaper, but to the contrary, significantly more expensive"
Headline in Dutch @Volkskrant yesterday, 9 days before the elections here. "Consumers and companies will pay 92% more for electricity and natural gas by 2030".
Hmm, let's look into that.
Firstly, as others have already pointed out too, it's a comparison between 2020 and 2030. In 2020, energy was cheap: Covid reduced demand, and Russia hadn't started its energy war and attack on Ukraine yet.
Compared with 2023, not a lot would remain of the "+92%".
Looking into the forecasted price increase 2020-2030 it has three components: 1. Tax (Belasting) +€5 billion. That'd be a political choice, which has little to do with the energy transition. 2. Grid (Netbeheer) +€5 billion. Increase to be expected indeed.
But ...
A problem for French nuclear power producer EDF: its total production cost (in the old power plants) is 60 €/MWh, according to the regulator, but govt forces it to sell a big chunk at 42 €/MWh.
60 €/MWh is not a bad cost in the current European electricity market, but it's also a reality check for those here who think nuclear power is practically for free after the investment in the power plant is done.
