European Network of System Operators for Electricity are warning that the solar eclipse coming next month will pose an “unprecedented test” for Europe’s power supplies. The solar eclipse is due to take place on March 20 and marks the first time that Europe’s solar-energy use has been significant enough to disrupt its grids. In 1999, the last significant solar eclipse of this magnitude took place but only a tiny percentage of electricity supplies relied on solar energy.  Now, nearly 3 percent of Europe’s total electricity supplies are dependent on the sun, according to Eurostat. Transmission system operators have been preparing for the eclipse for months, ENTSOE said, but warned it still posed a threat to Europe’s electricity system. FULL REPORT
