The comprehensive mandates that solar, wind and battery power dominate the energy mix in all other New England states will raise electric rates in New Hampshire $74 billion by 2050, according to the report that a group of conservative free-market think tanks released Tuesday.

Across the rest of New England, the move to set an 80% target to reduce carbon-based emissions and expand the use of green renewables will raise all electric rates in the region by $815 billion in 26 years, costing the average residential customer annually $99 more, the report concluded.
