Controlled EV charging cuts power costs 50% – even more with wind
Controlled EV charging cuts power costs 50% – even more with wind

Two truths are clear about electric vehicles today: Charging them is cheaper than filling up with gasoline, and they hold immense potential to boost renewable energy integration by serving grid operators as countless energy storage units. So what if those benefits were combined?
....
According to the study of various EV charging scenarios modeled across New York State’s regional grid, controlled EV charging by grid operators holds the key to unlocking the combination of lower power prices, higher wind energy integration, and more emission-free vehicles on the road.
Misplaced Fears Of EV Charging Spiking Power Costs?
It stands to reason as more EVs plug into the grid, grid operators will have to dispatch more generation to keep all those Leafs and Teslas juiced up. ...
Controlled Charging + Wind Energy = Big Savings
....regardless of power generation capacity scenarios, EV charging costs fall even further when large amounts of wind energy are present on the grid. In fact, when wind penetration reaches 20%, controlled charging creates an additional 6-13% in cost reductions.
That level of wind penetration isn’t typically sustained on U.S. grids, but it has absolutely been reached with growing frequency on regional grid systems in Texas and the Midwest – meaning the CMU results could already be manifesting themselves if proper vehicle-to-grid controls were in place.
Even better, the CMU research underlines the value EVs can have on maximizing renewable energy when it’s available. “Controlled charging could also help manage fluctuations from renewable energy sources like wind and solar power,” said Jaramillo.
Accelerating Toward A Smarter, Cleaner, Cheaper Future
While the researchers noted additional studies were needed to fully understand the total cost and emissions implications of EV charging, the CMU study is yet another example of how important EVs are to our clean energy future and adds to research showing the the grid can handle EV integration without crashing.
