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.
