Germany sets new solar power record with 22 GW electricity

27 Mai 2012

Berlin: German solar power plants produced a world record 22 gigawatts of electricity - equal to 20 nuclear power stations at full capacity - through the midday hours on Friday and Saturday, the head of a renewable energy think tank said.
The German government decided to abandon nuclear power after the Fukushima nuclear disaster last year, closing eight plants immediately and shutting down the remaining nine by 2022.
They will be replaced by renewable energy sources such as wind, solar and bio-mass.

Norbert Allnoch, director of the Institute of the Renewable Energy Industry (IWR) in Muenster, said the 22 gigawatts of solar power per hour fed into the national grid on Saturday met nearly 50 per cent of the nation's midday electricity needs.
"Never before anywhere has a country produced as much photovoltaic electricity," Allnoch told Reuters. "Germany came close to the 20 gigawatt (GW) mark a few times in recent weeks. But this was the first time we made it over."
The record-breaking amount of solar power shows one of the world's leading industrial nations was able to meet a third of its electricity needs on a work day, Friday, and nearly half on Saturday when factories and offices were closed.
Government-mandated support for renewables has helped Germany became a world leader in renewable energy and the country gets about 20 per cent of its overall annual electricity from those sources.
Germany has nearly as much installed solar power generation capacity as the rest of the world combined and gets about four percent of its overall annual electricity needs from the sun alone. It aims to cut its greenhouse gas emissions by 40 per cent from 1990 levels by 2020.
Sunshine
Some critics say renewable energy is not reliable enough nor is there enough capacity to power major industrial nations. But Chancellor Angela Merkel has said Germany is eager to demonstrate that is indeed possible.
The jump above the 20 GW level was due to increased capacity this year and bright sunshine nationwide.
The 22 GW per hour figure is up from about 14 GW per hour a year ago. Germany added 7.5 GW of installed power generation capacity in 2012 and 1.8 GW more in the first quarter for a total of 26 GW capacity.
"This shows Germany is capable of meeting a large share of its electricity needs with solar power," Allnoch said. "It also shows Germany can do with fewer coal-burning power plants, gas-burning plants and nuclear plants."

Allnoch said the data is based on information from the European Energy Exchange (EEX), a bourse based in Leipzig.

Dans ce pays, l’expansion de la production renouvelable est considérable depuis la décision du pays de sortir du nucléaire. Le lundi de Pentecôte aura été une journée 100% renouvelable, où, pendant quelques heures, le pays a entièrement fonctionné avec de l’énergie renouvelable. Le raccordement de ces centrales solaire au réseau allemand est donc long est compliqué, il doit suivre la cadence du croissance du secteur solaire.

Photovoltaic solar energy in Germany hits new record level

june 10, 2012

German utilities say solar power reached a new record level in May when it produced about 10 percent of the country's overall electricity.

The BDEW utility lobby group said Friday the production was up 40 percent on the year because of favorable weather conditions and a continuing boom in new solar panel installations.

Germany decided after last year's Fukushima disaster in Japan to phase out nuclear power by 2022. Renewable energies are set to generate 30 percent of the electricity by then, and 80 percent by 2050.

All renewable energy sources - including wind power and biomass plants - last year accounted for about 20 percent of the country's electricity, but that share appears to be rising as subsidies and investment incentives fuel a boom in new installations.
