One of its electric cars is used by Green Mountain Power to illustrate how battery-powered vehicles could enable the grid to meet future peak requirements. At its Colchester office in the month of October, the utility built a bi-directional Fermata EV charger, which now is harvesting electricity during energy peaks from the corporation’s 2019 Nissan Leaf. The Leaf is used by workers daily, charges at the GMP office but has joined the increasing stored energy network of the Green Mountain Power, which comprises home batteries such as Tesla Powerwalls.

If more Vermonters turn to Electric cars, the Nissan EV battery holds almost 4 times as much energy as one Powerwall, demonstrating the great ability to rely on electric cars to react to peak demands on the grid. “This is an essential step in demonstrating that vehicle-to-grid technology is practical,” Mari McClure, Green Mountain Power’s president as well as chief executive officer, said in a statement.

Green Mountain Power spokeswoman Kristin Kelly informed the Burlington Free Press Monday that in the coming year, the company will give business customers who wish to electrify their vehicles a vehicle-to-grid pilot scheme. Kelly stated peak demand for electricity typically comes from 6-9 p.m. when cars are expected to be parking for the day in company fleets anyway. The costliest hours for charging electric cars are often moments of peak demand.

Green Mountain Power has not yet decided whether it can supply residential consumers with the vehicle-to-grid service. Electric car consumers who sign up will be aware of when peak demand is expected to happen when the utility carries out the service, and will choose to turn out of getting electricity pulled from their vehicles. However, Kelly points out that since electricity during high demand is more costly, it makes perfect sense to be able to charge your car overnight or during other off-peak hours rather than after a busy event.

She also stated that electric cars involved in the vehicle-to-grid scheme wouldn’t even be depleted of electricity except during a peak event. Green Mountain Power already has a scheme in which electric vehicles’ drivers commit to minimizing their cars’ charging rates at peak demand. These customers were given free chargers in exchange. “We attempt to make it as efficient as possible,” said Kelly. “The purpose they get an electric car is to be able to use it. We’re very cautious about that.”
