Three years ago, the nation’s top utility executives gathered at a Colorado resort to hear warnings about a grave new threat to operators of America’s electric grid: not superstorms or cyberattacks, but rooftop solar panels.
If demand for residential solar continued to soar, traditional utilities could soon face serious problems, from “declining retail sales” and a “loss of customers” to “potential obsolescence,” according to a presentation prepared for the group. “Industry must prepare an action plan to address the challenges,” it said.
The warning, delivered to a private meeting of the utility industry’s main trade association, became a call to arms for electricity providers in nearly every corner of the nation. Three years later, the industry and its fossil-fuel supporters are waging a determined campaign to stop a home-solar insurgency that is rattling the boardrooms of the country’s government-regulated electric monopolies.
The campaign’s first phase—an industry push for state laws raising prices for solar customers—failed spectacularly in legislatures around the country, due in part to surprisingly strong support for solar energy from conservatives and evangelicals in traditionally “red states.” But more recently, the battle has shifted to public utility commissions, where industry backers have mounted a more successful push for fee hikes that could put solar panels out of reach for many potential customers.
In a closely watched case last month, an Arizona utility voted to impose a monthly surcharge of about $50 for “net metering,” a common practice that allows solar customers to earn credit for the surplus electricity they provide to the electric grid. Net metering makes home solar affordable by sharply lowering electric bills to offset the $10,000 to $30,000 cost of rooftop panels.
A Wisconsin utilities commission approved a similar surcharge for solar users last year, and a New Mexico regulator also is considering raising fees. In some states, industry officials have enlisted the help of minority groups in arguing that solar panels hurt the poor by driving up electricity rates for everyone else.
“The utilities are fighting tooth and nail,” said Scott Peterson, director of the Checks and Balances Project, a Virginia nonprofit that investigates lobbyists’ ties to regulatory agencies. Peterson, who has tracked the industry’s two-year legislative fight, said the pivot to public utility commissions moves the battle to friendlier terrain for utilities. The commissions, usually made up of political appointees, “have enormous power, and no one really watches them,” Peterson said.
Industry officials say they support their customers’ right to generate electricity on their own property, but they say rooftop solar’s new popularity is creating a serious cost imbalance. While homeowners with solar panels usually see dramatic reductions in their electric bills, they still rely on the grid for electricity at night and on cloudy days. The utility collects less revenue, even though the infrastructure costs — from expensive power plants to transmission lines and maintenance crews — remain the same.
Ultimately, someone pays those costs, said David K. Owens, an executive vice president for Edison Electric Institute, the trade association that represents the nation’s investor-owned utilities.
“It’s not about profits; it’s about protecting customers,” said Owens, said. “There are unreasonable cost shifts that do occur [with solar]. There is a grid that everyone relies on, and you have to pay for that grid and pay for that infrastructure.”
