Thorough planning of EV charging station placement, particularly with a larger emphasis on office charging, may reduce the necessity for extra energy crops, in accordance with a brand new MIT examine.
Printed within the journal Cell Reviews 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 increased electrical energy demand and necessitate extra energy crops. Researchers argue that smarter planning will each reduce the necessity for extra energy crops and make the most of extra photo voltaic capability.
As a substitute of assuming that almost all EV drivers will cost their vehicles at residence within the early night, after getting residence from work, researchers name for extra office charging. This can make the most of considerable photo voltaic producing capability at mid-day as a substitute of making an attempt to faucet into the grid within the early night, when demand and peak masses are usually increased.

House 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 probably rewarding drivers with decrease electrical energy charges.
“Combining delayed residence charging and office charging generally is a significantly profitable technique,” researchers mentioned in a press release, including that choices about charger places ought to emphasize these two eventualities.

That conclusion aligns intently with what an Vitality Division examine identified years in the past: that focusing charging round properties and workplaces may very well be extra essential than simply putting chargers all over the place. And California warmth waves in 2021 and 2022 helped underscore what finest helps keep away from using “peaker” sources—and forestall brownouts.
Nonetheless, a part of implementing such a technique will likely be altering employers’ angle towards onsite charging. Common Motors has dedicated to a excessive variety of EV chargers for its workers, however different corporations have to see office EV charging as greater than a perk for its staff, a 2019 report discovered.
