NEWS: Massachusetts’ least-cost 2050 peak power mix is combustion-free: report

Can Massachusetts affordably replace fossil-fuel peakers for a cheaper combustion-free grid by 2050? (Utility Dive)

  • A report prepared for the Massachusetts Clean Peak Coalition argues the state's most cost-effective 2050 peak grid—when factoring in health and climate costs—relies on 6.4 GW of wind, 6.9 GW of storage (mostly multi-day), and 4.2 GW of demand response.

  • Driven by the electrification of heating and cars, the state is projected to flip to a winter-peaking system by the mid-2030s. Currently, regional market designs favor keeping aging thermal plants online rather than incentivizing storage to survive long, sunless cold snaps.

  • Regional power producers argue the current environment demands "energy addition, not retirement." Pointing to the recent weeks-long freeze, they say the New England grid only survived because rarely used, high-emitting oil plants had to run nonstop for weeks to meet the surging demand.
