Beef Who Gets the Excess Electricty

Illustration by Mr. Biscuit

Solar power is having a major moment. It's growing faster than any other energy source—in 2014, a new system was installed in the Us every iii minutes—while the price of a typical panel has dropped 63 pct since 2010. By 2016, experts predict that solar will be equally cheap or cheaper than conventional electricity in well-nigh states. But solar companies are warning that the boom could before long finish, if utilities and some Republican land lawmakers have their way.

Under current utility pricing schemes, a poor family of four in California's AC-dependent Central Valley can end up paying rates far higher up the national average—while a Google-employed available millionaire gets a bargain.

Power companies' beef with solar boils down to a clever payment organisation that was largely responsible for bringing about the solar boom in the beginning place—a practice known as cyberspace metering. Most solar homes aren't really "off the grid": They stay connected to transmission lines, using regular power when their panels aren't operating (like at dark). But they also feed electricity into the grid when they produce more than they tin can use.

Sounds bang-up, right? Not really, say the power companies. They pay solar homeowners for their backlog kilowatts—but argue homeowners aren't paying their off-white share for grid maintenance. That has utilities in revolt, and the fight has reached a fever pitch in Northern California, where the land's largest utility, Pacific Gas and Electrical, serves more residential solar homes than any other.

Like many utilities, PG&E charges customers on a multitiered price scheme—the more electricity yous use, the more than you pay per unit. That can incentivize power hogs to conserve, but it can also mean that a poor family unit of four in California'southward Ac-dependent Central Valley can end up paying rates far in a higher place the national average (and what it actually costs PG&Eastward to serve them), while a Google-employed bachelor millionaire gets a deal. If that tech dude decides to install solar panels, he pays even less—fifty-fifty though he still uses the grid.

To be fair, customers who generate their own electricity as well save the utilities money, causing less wear and tear on transmission lines and less power lost forth the way. But a study commissioned by California'due south Legislature constitute that in the Aureate Country at least, these benefits do not fill the pigsty left past lost revenue. Cyberspace metering cost the state'south privately owned utilities $254 meg in 2012, a cost tag estimated to spring to $ane.i billion per yr by 2020 as an estimated 500,000 more homes go solar.

The solar manufacture shot back with a study of its own, arguing that those costs are modest compared with the roughly $32 billion that California'southward major utilities earned in 2013 and that, for PG&Eastward, the problem is not really caused by solar but by the huge gap—well-nigh threefold—between the company'due south lowest and highest rate tiers. Since solar is bonny to high-tier customers, who stand to salvage the near coin, each one who saves by installing a system is a big blow to the utility'south lesser line. Smoothen out the rate tiers, the study suggests, and the trouble disappears.

In the future, utilities will accept to act more like grid managers, connecting power from a host of sources—like data flowing into a server from many places.

In 2013, California lawmakers told the state's utilities to do just that. PG&E's proposed solution, set up to be voted on by state regulators in the spring, would reduce the number of toll tiers and add a fixed monthly grid maintenance surcharge. The problem is that the fixed charge will erode the cost advantages of going solar, since you tin't avoid information technology just by using less power from the filigree. Sanjay Ranchod, a policy analyst for the solar installer SolarCity, sees the change as a sneaky way for the utilities to kneecap the contest. Imposing a fixed monthly accuse, he says, is "one way you can inhibit the growth of distributed solar."

Similar battles are playing out from Utah to Wisconsin, as utilities fight to roll dorsum internet metering, restructure their rate systems, or impose special fees for solar users—and information technology'southward like shooting fish in a barrel to see why ability companies are sweating. The American Society of Civil Engineers estimates that the gap between the toll of maintaining the Us filigree and the available funds will grow by $xi billion per year through 2020, since the revenue streams utilities have traditionally relied on to pay for those costs—investments in big ability plants they can recover through increased sales—are drying up.

John Farrell, a programme director at the Minneapolis-based Institute for Local Self-Reliance, argues that to succeed down the line, utilities volition have to act more than like grid managers, connecting power from a host of sources (much like information flowing into a server from many places) and investing in technology that helps consumers employ power more efficiently. "There's no consequence 10 or 20 years from now that looks annihilation similar what utilities have been earlier," Farrell says. "It'south going to happen anyway, and you just have to cull whether you're gonna like information technology or non."
