In this outlook we have extended our forecast to 2040 (from 2036) to help give longer visibility around prices supply and demand and generator economics. A number of other changes stand out. Long term electric demand is higher thanks in large part to a higher penetration of electric vehicles. In terms of thermal generation many US coal and nuclear reactors reach the end of their 60 year life and retire. As a result North America power gas demand will double over the forecast.
