Germany generated that much renewable energy, they actually paid people to use it!

17 May

What a time to be alive – on Sunday 8th May 2016, Germany produced an incredible amount of renewable energy. For a few hours, the European nation went full ‘green’. Its power grid had surplus, and for a few hours residents actually earned money from using electricity, rather than paying for it. We were just as shocked as you!

The weather was so sunny and windy that at about 1pm in the day, the wind, hydro, solar and biomass plants in Germany generated 87% (55GW) of the entire amount of power (63GW) being consumed in the country. It’s an astonishing achievement and one that unfortunately the industry just was not expecting.

In 2015, Germany’s renewable energy mix was at 33% but Germany managed to use the sun, wind and rain to provide 87 per cent of an entire country’s energy requirements which is an incredible achievement. Usually, renewables just top up the main supply. Gas plants were actually shut down due to the green surge, but nuclear and coal plants couldn’t suspend activity fast enough. It meant the grid was overrun with power.

So Germany’s target of becoming 100% renewable by 2050 (which Denmark is currently hitting) seems not as ambitious as once thought. Germany will of course need to keep some of its nuclear and coal plants running due to the unpredictability of its renewable energy sources as they are dependent on the weather. In July last year, Denmark’s wind power was generating 140% of its demand, meaning energy could be sent over to Germany, Norway and Sweden.

At the moment there is a north/south split in the country, as wind turbines are located mostly in the north of Germany and solar power plants in the south. The authorities are also wanting to phase out nuclear power by 2022. With the country making exciting gains towards its goal, experts believe Germany to be a good role model for other developed countries.

It has been argued that the grid needs to become more flexible in order for the transition to renewable energy to be successful. Presently, renewable energy plants generating a lot of energy on sunny and blustery days have to push it into the grid, resulting in inefficiency and these negative prices. But with developed grid management and power storage technology, sudden spikes could be handled better and utilised in a more effective way.
