Study: Rooftop Solar Customers Don't Raise Costs For Others

A new study commissioned by the Nevada Public Utilities Commission finds that rooftop solar panel owners taking part in the state's ongoing net metering program won't be raising the electric bills of their non-solar neighbors.

The study, conducted by the San Francisco-based energy consulting firm Energy + Environmental Economics (E3), found that despite dire predictions from utilities in other states, net metering customers in Nevada will have "no substantial impact" on costs borne by non-solar ratepayers.

Instead, net metering customers will allow the state savings of somewhere around $166 million in avoided transmission network and generation costs, all of which would have shown up on Nevadans' electric bills.

Does LADWP Want to Charge Solar Customers For Grid Access?

A report from the Los Angeles Department of Water and Power suggests that the utility doesn't want to expand one of its most popular rooftop solar programs unless it can charge participants more for using its power grid at night. But unlike its investor-owned counterparts elsewhere in the country making the same argument, LADWP would rather expand a different solar incentive program instead, and that program might well prove more effective in making Los Angeles a solar city.

That's the gist of part of a recent report from LADWP to the City Council, in which the utility's General Manager Marcie Edwards suggests that in order to expand the utility's "net energy metering" program beyond its current cap of 310 megawatts, LAWDP would need to "unbundle" the rate paid to solar customers for energy they put back into the grid. Edwards says that will keep utility customers who don't have solar panels from paying more than their fair share of the cost of maintaining the city's power grid.

The idea that non-solar ratepayers are paying more than their fair share of grid maintenance costs than customers with net metering arrangements has gotten a lot of traction nationwide in recent months, in part due to a push by the Koch brothers' American Legislative Exchange Council to make net metering an issue. Solar advocates point out that rooftop solar actually saves ratepayers money by reducing the need for new power plants and transmission lines. But LADWP may be carving out a third path in the controversy: pushing for an expanded feed-in tariff program as an alternative to net metering.

A Big Cut for L.A. Emissions Proposed

A Los Angeles city councilman said today he wants to set a goal of dramatically reducing greenhouse gas emissions in Los Angeles by 2050.

Other cities including San Francisco, New York, Toronto, Boston, and Chicago already have committed to cutting emissions to 80 percent below 1990 levels by 2050.

"It's high time Los Angeles did the same," said Councilman Paul Koretz, who joined a coalition of clean energy advocates at City Hall to call for a similar goal in Los Angeles.

Koretz warned that if nothing is done to scale back pollution, environmental disasters such as droughts, floods, and fires could escalate worldwide.

"We have the greatest challenge any generation has ever faced looming before us," Koretz said. "And here, locally, we're in the worst drought in California history -- that's our weather extreme.

Feds Set To Issue First Eagle Kill Permit To California Wind Facility

The U.S. Fish and Wildlife Service is preparing to issue its first-ever take permit to allow for the accidental killing of golden eagles at a California wind facility. Under the terms of the permit, the Shiloh IV Wind Project, a 100-megawatt wind facility in Solano County's Montezuma Hills near Rio Vista, will be allowed to kill up to five golden eagles over a five-year period without incurring penalties under the Bald and Golden Eagle Protection Act (BGEPA).

In return, the project's owners, EDF Renewable Energy, will pay the utility Pacific Gas & Electric to retrofit 133 power poles in Monterey County to reduce the chances that eagles landing on them will be electrocuted. Electrocution from power lines is a significant hazard to eagles and other raptors. USFWS holds that the mitigation will actually result in fewer eagle deaths overall.

The take permit will be valid for five years. USFWS is currently proposing to extend future take permits under BGEPA to 30-year durations, a plan for which they found themselves hauled into court earlier this month.

Panel Discards Scientists' Recommendations on Wildlife Kills at Solar Plant

A task force charged with addressing the burgeoning issue of bird and bat deaths at the Ivanpah Solar Electric Generating System (ISEGS) has dismissed many of the recommendations in a report on the topic issued by the U.S. Fish and Wildlife Service's forensics lab, according to documents released by the California Energy Commission.

That report by USFWS's National Fish and Wildlife Forensics Laboratory, which ReWire reported on in April, suggested that actual levels of wildlife mortality and injuries at ISEGS are being obscured by inadequate surveys for injured and dead animals, and proposed several measures by which those surveys could be made more scientifically rigorous.

But according to minutes of a May 20 meeting of the ISEGS Avian & Bat Technical Advisory Committee (TAC), an interagency body convened to assess the wildlife mortality issue at the plant, members dismissed a number of apparently common-sense steps to increase the validity of carcass surveys -- and one likely method to sharply reduce injuries to birds during migration season.

Fed Agency OKs Controversial Power Storage Project Near Joshua Tree NP

A federal agency has given the go-ahead to a power storage project adjacent to Joshua Tree National Park that opponents say could seriously harm both the park's wildlife and local groundwater.

The Eagle Mountain Pumped Storage Project, proposed for the old Kaiser Eagle Mountain mine in Riverside County's Chuckwalla Valley would store and release surplus electrical power by pumping water between two reservoirs. During the day when local solar and wind energy plants produce power, the water would be pumped uphill, then allowed to run downhill through turbines to recoup some of that energy when renewable energy sources aren't producing power.

But the plan calls for 21,000 acre-feet of water in those reservoirs, and project proponent Eagle Crest Energy plans to get that water -- and the 100,000 acre-feet needed to replace evaporated water over the project's 50-year lifespan -- from the local aquifer. That has locals worried about water availability and quality, and the presence of huge reservoirs in the middle of the desert poses problems for Joshua Tree's beleaguered wildlife.
