Duke Energy, General Motors, Ford and BMW are teaming up to launch an electric vehicle (EV) pilot programme in North Carolina aimed at bringing certainty to charging costs.

Duke Energy’s 12-month EV Complete Home Charging Plan pilot will allow residential consumers in North Carolina to use up to 800kWh per month to charge an EV at home for a fixed monthly fee of $20 in its Duke Energy Carolinas service area and $25 in its Duke Energy Progress service area.

The average EV driver uses less than 15kWh on a given day, meaning the pilot will offer peace of mind for participants with nearly twice the amount per month needed by the average driver.

Those who own or lease a qualifying EV will receive an invitation to participate from their respective EV manufacturer and can enrol in the programme starting this month. Additional enrolment details will be provided to participants ahead of the programme launch in November.

“North Carolina has ambitious goals to reduce greenhouse gas emissions and we’re supporting those efforts,” said Kendal Bowman, Duke Energy North Carolina state president. “Increasing the numbers of EVs while reducing the number of gas-powered vehicles on the road will help our state move closer to carbon neutrality.”

Customers will be able to input their desired state of charge and preferred departure time using an application provided by their car maker that then creates a charging schedule to optimise their preferred EV charging times.

Duke Energy is working with General Motors, Ford and BMW of North America as a part of the Open Vehicle Grid Integration Platform (OVGIP), which enables the management of EV charging from multiple car makers in a grid-friendly and EV driver-centric manner. OVGIP data will allow Duke Energy to measure customer charging data directly from the enrolled vehicles, eliminating the need to install a second meter. Each car maker owns and manages its own charging application that communicates through OVGIP.

During the pilot, participants will input their desired time to reach a certain state of charge, and their car maker will optimise their EV charging schedule to meet their needs while attempting to avoid charging during the grid’s peak hours. This process can increase convenience by helping provide a charged vehicle when they need it, while contributing to grid stability.

“The average EV owner is already saving about $1000 per year on fuel costs compared with a traditional vehicle,” said Bowman. “A predictable monthly subscription charge on top of that is going to ensure predictable savings when charging. Beyond cost savings, EV charging at home tends to be convenient because drivers can leave the house with a fully charged vehicle and lessen the number of trips to public charging stations.”

An important component of the strategy to ready the grid for growth from transportation electrification is the ability to encourage EV charging to take place when the grid has available capacity. As part of the pilot, Duke Energy will call up to three demand response events per month to help balance grid demand. Demand response notifications will be communicated to pilot participants by the car makers at least 12 hours in advance of the event and include the date and hours to avoid charging an EV. Participants may opt out of demand response events up to four times during the pilot.

“EV charging has the added benefit of flexibility, meaning charging can be managed – such as shifting charging to off-peak hours – which is important in limiting cost increases and mitigating peak demands,” said Harry Sideris, executive vice president at Duke Energy. “Duke Energy has been strategically planning and enabling the grid for a future with many more EVs on the road, and is also making data-driven investments to improve reliability, strengthen the grid, expand technologies and provide customers with the intelligent information they need to make smart energy choices and save money.”
