Thorough planning of EV charging station placement, particularly with a larger emphasis on office charging, might reduce the necessity for extra energy crops, in response to a brand new MIT examine.
Printed within the journal Cell Studies Bodily Science, the study 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 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 an alternative of assuming that the majority EV drivers will cost their vehicles at house within the early night, after getting house from work, researchers name for extra office charging. This may benefit from ample 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 usually greater.

House charging nonetheless has a spot on this technique, so long as drivers delay charging till later at evening. As utilities and former research have emphasised, this pushes EV charging into intervals of decrease demand, using extra grid capability and probably rewarding drivers with decrease electrical energy charges.
“Combining delayed house charging and office charging could be a notably profitable technique,” researchers mentioned in an announcement, including that selections about charger areas ought to emphasize these two situations.

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