In 2006, a record-breaking heatwave pushed New England's power grid to its limit. A decision made years later is now saving people up to $149 million during extreme summer heat

New England's electricity grid faced challenges during a 2006 heatwave and investments in rooftop solar panels began around 2008 to 2010. These solar systems generated significant electricity during a recent heatwave. Rooftop solar helped save customers millions of dollars over one week. Energy efficiency measures also contributed to lower electricity bills.
