As Republicans cast doubt on the state’s 2035 electric vehicle mandate, Gov. Ned Lamont’s administration says it’s confident there will be enough charging stations to meet demand when the requirement for all new car sales to be electric takes effect. Automakers are preparing for the switch, rolling out electric versions of models ranging from SUVs to pick-up trucks, and electric utilities are working to develop the distribution framework needed to supply nearly twice as much electricity by 2050. Eversource needs to build 14 new substations — at a cost of $100 million to $150 million each — to reliably serve the additional 4 GW of electricity needed to power EVs by 2040, Chatterjee said. Eight existing substations need to be upgraded, at a cost of $10 million to $25 million each, he added. That’s an overall estimated investment of up to $2.3 billion to prepare for larger-scale EV adoption — costs likely to be borne, wholly or partially, by ratepayers.
