August 21 Solar Eclipse

August 17, 2017

Ontario will experience a partial solar eclipse between 1:00 pm and 4:00 pm on Monday, August 21. This unique celestial event is the first solar eclipse to take place since large amounts of solar generation have been installed across North America. Read what it means for Ontario’s power system and how the IESO is planning for this event on our website. Follow along with us on Twitter for updates on how our control room is balancing Ontario electricity demand and supply during the eclipse.
