New England Utilities Turn Parked Electric Cars into a Paid Power Resource for the Grid
July 22, 2024 — In a significant shift for energy management, utility companies in New England have begun pilot programs that financially compensate electric vehicle owners for allowing their parked cars to supply power back to the local electricity grid. This initiative, known as vehicle-to-grid (V2G) technology, aims to leverage the massive collective battery capacity of EVs to enhance grid reliability and reduce dependence on fossil-fueled power plants during periods of high demand.
The core of this emerging strategy involves a simple trade: utility companies gain access to a portion of the energy stored in an EV’s battery during critical peak hours, and in return, the vehicle owner receives a direct financial incentive. For participants, this transforms an idle asset—a parked car—into a potential revenue stream, simply by keeping it plugged into a compatible bidirectional charger at home.
The Pilot Programs and Their Financial Incentives
Leading the charge are two major utility providers, National Grid and Eversource, which have launched initial pilot programs in the region. These are not merely conceptual tests but active engagements with a select group of EV owners. The primary draw for participants is a tangible financial benefit. Reports indicate that a typical household enrolled in National Grid’s pilot could earn approximately $1,250 per year. This payment structure is designed to offset electricity costs and add value to EV ownership, making the proposition highly attractive.
“The value for the customer is potentially in hundreds of dollars per year, maybe even thousands, depending on grid needs and participation,” noted Russell Vare, a vice president at The Mobility House, a firm experienced with similar V2G projects in Europe. The current application window for these pilot programs is limited, with enrollment for the current phase closing on September 30, highlighting the early-adopter nature of the opportunity.
Technical Hurdles and Eligible Vehicles
A significant barrier to widespread immediate adoption is hardware compatibility. The pilot programs require a specialized bidirectional charging setup, which is not yet standard on most electric vehicles sold in the U.S. market. Consequently, participation is currently restricted to owners of specific models engineered with this capability.
According to program details, eligible consumer vehicles include the Nissan Leaf, Ford F-150 Lightning, Kia EV9, and upcoming models like the Volvo EX90 and Polestar 3. This limitation underscores a critical juncture for the automotive industry; as more manufacturers integrate V2G-ready technology into new models, the pool of potential grid-supporting vehicles will expand exponentially. With over 150,000 EVs already registered in Massachusetts alone, the future scalable impact is considerable.
Addressing Grid Strain and Environmental Goals
The driving force behind these utility investments is a pressing grid management challenge. During extreme weather events, such as heat waves or cold snaps, electricity demand can spike dangerously. Traditionally, utilities activate “peaker plants,” which are often powered by natural gas or oil. These plants are not only expensive to operate but also contribute significantly to carbon emissions and local air pollution.
V2G technology presents a cleaner, decentralized alternative. By drawing power from thousands of parked EVs during these peak periods, utilities can flatten demand curves and reduce the need to fire up polluting peaker plants. This helps lower overall energy costs, enhances grid stability, and supports state and regional carbon reduction targets. The concept demonstrates a dual benefit: it accelerates the transition to renewable energy by providing storage and flexibility, while simultaneously making electric vehicle ownership more economical.
Broader Momentum and Future Outlook
The initiative in New England is part of a broader, growing movement exploring the grid services potential of electric transportation. Public funding in Massachusetts has already supported related projects, such as installing two-way chargers for electric school buses. One bus in the city of Beverly reportedly generated over $23,000 in revenue over two years by selling surplus power back to the grid—a compelling proof of concept for larger vehicle fleets.
Industry experts view these pilots as essential learning platforms. “These demonstrations are going to help us answer critical questions and give us confidence that when we scale V2G, we can do so in a way that delivers reliable value for both the customers and the grid,” explained Kevin Boughan, a manager of strategy and business development at Eversource.
Looking ahead, the success of these programs hinges on wider automaker adoption of V2G technology, the development of standardized charging protocols, and the creation of favorable regulatory frameworks. As these elements fall into place, the vision of a dynamic, two-way grid where electric vehicles serve as mobile power plants is poised to become a mainstream reality, reshaping the economics of energy and transportation.
