Another heat wave is set to bear down upon the East Coast this week, one that could roil power markets this time around.

Two high-pressure systems will combine to drive temperatures into the 90s Fahrenheit (30s Celsius) starting Wednesday, kicking off a period of intense heat that should last through the weekend in Washington and Philadelphia, according to the U.S. Weather Prediction Center. As a result, power demand is set to rise every day this week on the biggest U.S. grid.
