Spain has cut its photovoltaic capacity for the first time
On April 17, when Spain's electricity demand plunged, pv capacity peaked at nearly 13.5GW, meaning it could meet 62.5% of the country's electricity demand. Wholesale prices fell from €168.50 ($182) per megawatt hour to just €3.70 per megawatt hour, according to AleaSoft, a Spanish energy forecasting service.
For the first time, Spain has cut its photovoltaic capacity, including production or suspension, as output exceeded its plan. Renewable power generation has been subject to such adjustment mechanisms since 2015, but the main cut has been in wind power.
Aleasoft said: "A large amount of renewable energy is being abandoned, which could have been generated at existing capacity and using the solar resources available on the day."
"According to the Solar generation curve, between 2:50 PM (CENTRAL European Daylight Time) and 4:00 PM, the pv generation decreased, from 10,710 MW recorded at 2:40 PM to 9,689 MWH at 3:50 PM. In addition, some producers claimed on social media that the grid operator Red Electrica de Espana (REE) had asked them to stop generating electricity." Aleasoft explains how this mechanism can be activated.
Aleasoft says the opportunity and role of energy storage in the power system will become more and more significant in the coming years. In the Iberian power market, a price difference of €100 / MWH per hour over the course of a day has become relatively common, providing an opportunity for energy storage technology. In addition, this is important for tuning services so that they can quickly respond to the need to balance electrical systems.(News from guangfu.bjx)
