Thorough planning of EV charging station placement, particularly with a higher emphasis on office charging, may lower the necessity for extra energy vegetation, in keeping with a brand new MIT examine.
Printed 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 increased electrical energy demand and necessitate extra energy vegetation. Researchers argue that smarter planning will each lower the necessity for added energy vegetation and make the most of extra photo voltaic capability.
As an alternative of assuming that the majority EV drivers will cost their vehicles at residence within the early night, after getting residence from work, researchers name for added office charging. It will reap the benefits 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.

Dwelling 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 doubtlessly rewarding drivers with decrease electrical energy charges.
“Combining delayed residence charging and office charging could be a significantly profitable technique,” researchers mentioned in a press release, including that selections 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 necessary than simply inserting chargers all over the place. And California warmth waves in 2021 and 2022 helped underscore what finest helps keep away from the usage of “peaker” sources—and stop brownouts.
Nevertheless, a part of implementing such a method will likely be altering employers’ angle towards onsite charging. Basic 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 employees, a 2019 report discovered.
