Thorough planning of EV charging station placement, particularly with a better emphasis on office charging, may reduce the necessity for extra energy vegetation, in response to a brand new MIT examine.
Revealed within the journal Cell Experiences Bodily Science, the examine makes use of information from New York Metropolis and Dallas to counter the narrative that an inflow of electrical vehicles will create massively greater electrical energy demand and necessitate extra energy vegetation. Researchers argue that smarter planning will each reduce the necessity for extra energy vegetation and make the most of extra photo voltaic capability.
As a substitute of assuming that almost all EV drivers will cost their vehicles at dwelling within the early night, after getting dwelling from work, researchers name for extra office charging. It will make the most of considerable photo voltaic producing capability at mid-day as an alternative of making an attempt to faucet into the grid within the early night, when demand and peak hundreds are typically greater.

Residence charging nonetheless has a spot on this technique, so long as drivers delay charging till later at night time. As utilities and former research have emphasised, this pushes EV charging into durations of decrease demand, using extra grid capability and doubtlessly rewarding drivers with decrease electrical energy charges.
“Combining delayed dwelling charging and office charging is usually a notably profitable technique,” researchers mentioned in a press release, including that choices about charger places ought to emphasize these two eventualities.

That conclusion aligns carefully with what an Vitality Division examine identified years in the past: that focusing charging round properties and workplaces could possibly be extra vital than simply inserting chargers in all places. And California warmth waves in 2021 and 2022 helped underscore what finest helps keep away from using “peaker” sources—and stop brownouts.
Nonetheless, a part of implementing such a method will probably be altering employers’ angle towards onsite charging. Common Motors has dedicated to a excessive variety of EV chargers for its staff, however different firms have to see office EV charging as greater than a perk for its staff, a 2019 report discovered.
