"If you’re a typical American, you get home from work and start flipping
switches and turning knobs — doing laundry, cooking dinner, watching TV. With
so many other folks doing the same, the strain on the electrical grid in
residential areas is highest at this time. That demand will only grow as the
world moves away from fossil fuels, with more people buying induction stoves,
heat pumps, and electric vehicles.
That’s a challenge for utilities, which are already managing creaky grids
across the United States, all while trying to meet a growing demand for power.
So they’re now trying to turn EVs from a burden into a boon. More and more
models, for instance, feature “vehicle-to-grid,” or V2G, capabilities, meaning
they can send power to the grid as needed. Others are experimenting with what’s
called active managed charging, in which algorithms stagger when EVs charge,
instead of them all drawing energy as soon as their owners plug in. The idea is
for some people to charge later, but still have a full battery when they leave
for work in the morning.
A new report from the Brattle Group, an economic and energy consultancy, done
for EnergyHub, which develops such technology, has used real-world data from EV
owners in Washington state to demonstrate the potential of this approach, both
for utilities and drivers. They found that an active managed charging program
saves up to $400 per EV each year, and the vehicles were still always fully
charged in the morning. Utilities, too, seem to benefit, as the redistributed
demand results in less of a spike in the early evening. That, in turn, would
mean that a utility can delay costly upgrades — which they need in order to
accommodate increased electrification — saving ratepayers money."
