Europe's power grids are bracing for potential strain as a full solar eclipse is set to occur on Wednesday evening. Experts caution that the temporary reduction in solar power generation during the event could place additional pressure on electricity systems already struggling with the impacts of extreme weather.
This summer's heatwaves have led to the shutdown of nuclear and coal power plants across the continent, while low water levels have impacted hydropower stations. Grid operators in countries like France and Spain are anticipating losses in solar power output and are preparing to balance the grid using alternative energy sources.
According to the Spanish grid operator Red Electrica, the eclipse could reduce Spanish solar power generation by as much as 5 gigawatts. This reduction is equivalent to approximately 13 percent of the maximum demand typically seen on a Wednesday in August.
In the United Kingdom, the National Energy System Operator estimates that solar output could drop by up to 1.3 gigawatts. This anticipated decrease is comparable to the output of two nuclear reactors.
The eclipse, the first to be visible in Europe this century, will begin in the UK shortly after 6 p.m. local time. It will not occur again in the region until 2081. Much of the UK is expected to experience an eclipse exceeding 90 percent, meaning the Moon will obscure more than nine-tenths of the Sun. This event will be the most complete solar eclipse seen in Britain since August 1999, when a similar phenomenon occurred in the mid-morning.
The intensity of the eclipse will vary across different regions. Western and Southwestern parts of the UK will witness a greater portion of the Sun being obscured, with Plymouth expecting up to 95 percent coverage. London is projected to see a 91 percent eclipse, while Shetland will experience an 88 percent eclipse.
In parts of Europe, the eclipse will be total. Northern and eastern Spain, the Balearic Islands, and northeastern Portugal will experience the complete obscuration of the Sun for more than two minutes. Nightclubs in Ibiza are reportedly preparing for a large-scale event in anticipation of the total eclipse.
