While the market for electric vehicles is heating up, with waiting lists for both the Nissan Leaf and the Chevy Volt and startup companies like Tesla, Arcimoto, and Coda Automotive upping their games, some industry watchers still wonder whether electric vehicles will ever become a significant part of the auto market.
But what if you could earn $1,000 a year with your electric vehicle, netting $440 after your fill-up costs? Would that be enough of an incentive to compensate for higher upfront costs and range anxiety?
For years, EV boosters have mulled the possibility of all those car batteries being used to store energy. In addition to drawing electricity, plugged-in cars would also be able to send electricity stored in their batteries back into the grid as needed, acting like tiny power plants.
The grid needs short-, medium-, and longer-term storage to run smoothly, and car batteries could most easily meet the short-term need, a process called frequency regulation. And as we ramp up our percentage of renewable energy from variable sources like wind and solar, the need for this service is growing. But why would car owners allow their cars to be used in this way? Enter the cash-back car.
The so-called vehicle-to-grid model, or V2G, has been a pet project of Dr. Willett Kempton’s since 1997. In an article published that year by Kempton and colleague Steven Letendre, they laid out the economics, the electric engineering, and how to calculate earnings.
Kempton then contacted his regional transmission organization (RTO), PJM Interconnection, which manages wholesale electricity in 13 states and the District of Columbia, and convinced it to make it possible to pay customers for providing this service.
For the last three years, Kempton has operated a pilot project at the University of Delaware, partnering with PJM and a couple of utilities, in which seven electric cars interact with the grid and receive monthly payments.
The service they provide is actually higher quality frequency regulation than the way grid operators have provided that service traditionally: by ramping extra “peaker” power plants up and down, which wastes electricity. It also takes the plants several minutes to ramp up or down. By contrast, batteries in the cars can deliver that service within seconds, making it a more valuable tool. “We’re providing a more valuable and responsive service,” said Kempton.
Federal Energy Regulatory Commission (FERC) Chairman Jon Wellinghoff agrees and believes that value should be compensated with higher payments than the peaker plants receive. He proposed a rule to that effect in February and expects it to become official within months.
The rule would apply anywhere that RTOs or independent system operators (ISOs) have a tariff for regulation services — nearly the entire country, except for the Southwest Power Pool service area: Kansas, Oklahoma, Nebraska and parts of Missouri, Arkansas, and Louisiana.
However, you can’t put your Leaf or Volt to work for you just yet.
To be able to offer frequency regulation service to the grid, cars need a bidirectional power system, so energy can flow both from the grid and to the grid, and software to allow the car to communicate with the grid. Most cars on the market today don’t have those features, although cars from Tesla and AC Propulsion have bidirectional power. “Daimler has announced the Smart fortwo will have this capability in 2012,” said Willett. These cars can also charge faster, at about a mile a minute, he said.
Willet expects that market signals, such as the FERC’s rule change and related RTO and ISO changes, will encourage automakers to make these features the norm in future models.
“If we get the rule out in six months and wholesale providers reset their payments to pay higher amounts for these kinds of services, that will drive car manufacturers to quickly integrate this technology into their cars to allow consumers to participate in these markets,” said Chairman Wellinghoff. “I think it could have an impact in as little as three years.”

Cars batteries are a good match with wind power because they mostly charge at night, when people are sleeping, and wind tends to peak at night. Right now, because demand plunges at night, wind generated at night is lower value or sometimes even dumped. Of course, if a lot of cars came online and charged during the day, generators would need to produce more daytime energy. That’s why it’s important to line up “the proper incentives to encourage the car owner to charge at night when the price is best,” said Ray Dotter, a spokesman for PJM.

Drivers decide when they will need the car and when it will be free for grid use. However, it does require a bit of planning. If you stray from your regular schedule, “You tell the car ahead of time,” said Kempton. “That’s why you get paid money. It’s a slight hassle for the driver. Although ‘telling’ likely means reserving it on your iPhone or on a browser at your home office.”
Another wrinkle: RTOs and ISOs aren’t equipped to manage power from individual cars. The energy generators and frequency regulators they work with must be of a certain size. So for cars to play, they have to aggregate.
PJM requires 500 kilowatts to be registered as a generator, although it may revise that down to 100 kilowatts by the end of the year. Still, that means vehicles have to be grouped together to be able to earn payment.
“One hundred kilowatts would require about 15 cars, some offline and some driving,” said Kempton. “The University of Delaware’s current fleet of seven cars is aggregated with a giant battery to meet the current 500 kilowatt requirement.
For this reason, fleets will likely be the first adopters.
The Department of Defense is intrigued and is studying the matter intently. Last week it put out an RFI to EV manufacturers, EV battery manufacturers, financing firms, and energy management companies for strategies to integrate EVs into DOD’s nontactical ground fleet on a large scale. The goal is to achieve cost parity between EVs and internal combustion vehicles, and one strategy for doing that is frequency regulation.
“Worldwide, the DOD has about 200,000 vehicles in its fleet so there’s a whole lot of opportunity there for us to look at creative ways to advance emerging technologies,” said Camron Gorguinpour, a special assistant to the United States Air Force for Installations, Environment & Logistics.
EVs are attractive to DOD for a range of reasons, including reduction of greenhouse gas emissions, enhanced energy security, and the ability to retain power during a crisis by pairing EVs with microgrids, said Gorguinpour. “And from an asset management point of view, it makes a lot of sense. We’d be putting money into something that sits 99 percent of the time. It would be great to have some value out of that.”
Gorguinpour expects it will take “months, not years” for the DOD to identify the best course of action. It is looking to deploy grid-integrated vehicles by summer 2012.
“DOD is taking this very seriously,” he said.
While still “purely on an exploratory level,” Blue Bird Corporation, a school bus manufacturer in Fort Valley, Georgia, is looking at building this technology into its buses,” said John Kwapis, its chief operating officer.
It seems like a natural fit. “When energy demand is at its peak during the summer months, school buses are at the school yard or bus depot,” he said. “And the amount of battery power needed for a school bus offers the grid a lot of capacity. It takes fewer school buses than cars to get to megawatt,“ he said.
But individual car owners may not be left out of the game for long. The University of Delaware is selling licenses to its proprietary aggregator technology to companies to interface between individuals and RTOs or ISOs.
“We have licensed the technology to one company and have an offer out to a second,” said Kempton. “Nuvve, with offices in San Diego and Copenhagen, has the right to act as an aggregator in all countries except the United States. They’re already making deals.”
Gregory Poilasne, Nuvve’s CEO, said Nuvve could pay one-quarter of an individual’s car loan up front in exchange for the owner plugging in the car at least 14 hours a day for eight years, “which means about 2 hours of charge and 12 hours for the market.”
In the next six months, Nuvve plans to roll out the program in Denmark, Hong Kong, and Taiwan because of their positive regulatory climates. Soon after it plans to move into Germany the Netherlands, Spain and the United Kingdom, said Poilasne, “… places where wind energy is taking a more important role because more wind energy means a high need for regulation.”
It’s a big — and rapidly growing — market. “The regulation market today worldwide is $6 billion, with $1.5 billion in the United States,” said Poilasne. “By 2020, it’s projected to be $12 billion worldwide, with $9.5 billion outside of the United States.”
Stateside, two companies are vying for the license to provide aggregation service to the U.S. market, said Kempton. “They are both very large companies in the power sector. They’d be prepared to move very quickly.” Kempton said the company that wins the U.S. license will be announced next week.
