US summer power markets are just warming up. A heat wave hit the central US in mid-July, leading to multiple alerts and records across two grid footprints, and a late July heat wave brought triple-digit temperatures to the Pacific Northwest, shrinking power exports to neighboring regions in the West. But the summer demand season is far from over, as forecasts for summer-like temperatures now extend into September, which means there’s likely much more on the way before things cool off. US power news editor Kassia Micek, power pricing analyst Karen Rivera, senior power and gas editor Mark Watson, and North American power analytics manager Morris Greenberg discuss what’s happened this season to date, and how things look down the curve.
