MISO again found planned generation retirements continue to outstrip additions in its third annual Regional Resource Assessment

MISO said its members may need to build up to 200 GW in new installed capacity by 2041 to meet reserve requirements while achieving renewable targets.

MISO's Regional Resource Assessment found there will be a persistent risk of capacity shortfalls as fossil plants retire and more renewables come online.

MISO announced that members will need to add almost 140 GW of capacity over the next two decades to meet carbon-reduction targets while maintaining reliability.
