Partial Solar Eclipse in 2021 – Why There Will Be No Blackout in Future: a Relaxed Scenario

Germany 2021: Angela Merkel is still the German Chancellor. It is perhaps her last term in office. But perhaps not. And there is once more the threat of a partial solar eclipse crippling the national grid across the whole country – just like six years before. But – stop. No. This time the Chancellor is happy and relaxed. She hums “…elektrisches Gefühl…” (that means “electrical feeling” and refers to a song by “Juli”), as she gets into her official car. It drives silently through the streets of the capital. One of almost two million electric cars now in Germany. The EU’s CO2 stipulations have been met for the first time. The change to greater energy self-sufficiency worth billions has been a success. Fossil fuels are a thing of the past – replaced by wind, hydroelectric power and biomass. The proportion of renewable energies is at a record level. And people are using photovoltaics right from the cradle. The Federal Government has achieved its objectives. Energy Management Is the Key In Germany too, where there is little sunshine, it is ‘cool’ to consume power generated yourself instead of feeding it into the grid and to manage your household, including the car, via intelligent electricity meters in conjunction with the “Internet of Things”. Using electric cars for free and making money with the battery too – a scenario that has become a day-to-day reality. And the techie lifestyle (finally) means cost savings. The electric driving experience is an emotional product which makes the e-car economical and the key for fine tuning the “Energiewende” (“energy transition”). The key to success lies in energy management. Battery management and the sale of appropriate storage capacities on the electricity market making it possible to completely save all electricity costs for driving. E-cars and rechargeable batteries are available as stationary storage units. They also take up power when there are overcapacities and the national grid becomes unbalanced. For instance, when the sun shines longer than forecasted or completely disappears, such as during the solar eclipse on 20 March 2015. And that’s why the Chancellor is not at all scared. Because she knows that the two million electric cars in her country will easily safeguard two hours of missing solar capacity with a feed-in power of 10 kW and a car battery capacity of 20 kWh. E-cars on the national grid. A scenario that does not have to remain a vision. In 2021, when the next partial eclipse occurs, we are expected to have around 50,000 MW of installed PV capacity in Germany. Electricity supply requirements are also growing alongside this. This means it is important in the context of the “Energiewende” to plan measures to ensure stability, as well as expanding renewable energies at the same time. The needs-oriented assurance of balancing power through sensible integration of electric cars into the grid is one of these essential measures. The first steps in this revolution have already been taken by The Mobility House (TMH) by connecting e-cars to a reliable charging station. The next step is bidirectional charging. Then the cars or batteries would actively contribute to the power supply, feeding electricity back into the grid when needed – including during a solar eclipse. The technical requirements for this V2G vehicle-to-grid charging are still only available in a few e-cars. The Mobility House and Nissan will implement this in Germany over the next few weeks as well. Fear of premature ageing of the battery is unfounded in this case. The charging range of the battery remains within a favourable range, nearly eliminating ageing problems. That is the pure “Energiewende”. It means there will no longer be any need for large power plants or storage units to prevent a blackout, soon. Charging with The Mobility House Many people question the grid stability described, which could already be commonplace by 2021, with respect to the imminent partial solar eclipse on Friday, 20 March 2015. At the very least, it could become extremely costly. If the sky gets dark between 9.38 and 11.49 am, the output from over one million solar energy plants in Germany will be abruptly lost, at least if it is not cloudy. The network operators have to compensate for this loss. If The Mobility House had its way, the solar eclipse on Friday would not be an issue at all. The company collaborates with all leading automotive manufacturers from BMW to Tesla, has connected more than 1,000 electric cars to the grid with charging stations and also aims to crack the two million mark by 2021. If the Chancellor plays along.
