Munich, June 9, 2016: Lots of sunshine, strong winds: The conditions in spring are ideal for renewable energies. Almost too ideal, as the Pentecost weekend 2016 demonstrated. An oversupply in the grid feed-in from solar and wind energy led at times to negative energy prices. Situations such as this make it clear that setting up an intelligent energy system, which optimally connects and controls energy producers, storage systems, consumers and grids, is essential for the energy supply of the future. The Smart Renewable Energy Forum at Intersolar Europe, the world’s leading exhibition for the solar industry and its partners, demonstrates how this can be achieved. Experts are set to present and discuss technologies and solutions from June 22-24, 2016 in hall B2, booth B2.131.
Over Pentecost, a stiff breeze was blowing on the German coast, the sun was shining in southern Germany, and industrial demand was low, as it was a public holiday. The result: For a short time, Germany initially came close to meeting its entire energy needs with energy from renewable sources. On Sunday (May, 8) between 11:00am and 12:00pm, solar and wind energy installations alone generated an output of over 48,000 megawatts (MW), equivalent to around 75% of the energy consumption. Altogether, renewable energies were able to cover 87% of the energy consumption – a milestone for the energy transition. The massive expansion of photovoltaic and wind power sites also causes problems, as many, particularly old, conventional power plants, cannot be controlled quickly enough. The consequence: At times, the price of power on the Leipzig Energy Exchange fell below zero. This means that anyone feeding electricity into the grid effectively had to pay their customers for taking the electricity off their hands.
