Los Angeles Power and Water officials have struck a deal on the largest and cheapest solar + battery-storage project in the world, at prices that leave fossil fuels in the dust and may relegate nuclear power to the dustbin.<\/p>\n\n\n\n

Later this month the LA Board of Water and Power Commissioners is expected to approve a 25-year contract that will serve 7 percent of the city’s electricity demand at 1.997\u00a2\/kwh for solar energy and 1.3\u00a2 for power from batteries.<\/p>\n\n\n\n

“This is the lowest solar-photovoltaic price in the United States,” said James Barner, the agency’s manager for strategic initiatives, “and it is the largest and lowest-cost solar and high-capacity battery-storage project in the U.S. and we believe in the world today. So this is, I believe, truly revolutionary in the industry.”<\/p>\n\n\n\n

It’s half the\u00a0estimated cost of power from a new natural gas plant.<\/p>\n\n\n\n

Mark Z. Jacobson, the Stanford professor who developed\u00a0roadmapsfor transitioning 139 countries to 100 percent renewables, hailed the development on Twitter Friday,\u00a0saying, “Goodnight #naturalgas, goodnight #coal, goodnight #nuclear.”<\/p>\n\n\n\n

The nuclear critic Arnie Gundersen, who predicted storage prices under 2\u00a2\/kwh four years ago\u00a0on the night Elon Musk unveiled the Tesla Powerpack, noted Saturday that his 2015 prediction was too high. He too said, “Goodbye coal, nukes, gas!”<\/p>\n\n\n\n

The Eland Project will not rid Los Angeles of natural gas, however. The city will still depend on gas and hydro to supply its overnight power. But the batteries in this 400-megawatt project will take a bite out of the fossil share of LA’s power pie.<\/p>\n\n\n\n

“It reduces the evening ramp (of natural gas) as the sun sets,” Barner\u00a0told\u00a0commissioners at their June 18 meeting. “As the sun goes down for our other 1,000 MW of solar that doesn\u2019t have batteries, the gas-fired generation and hydro have to compensate for that. So that net peak load in the evening will be offset with this facility. We\u2019ll be able to contribute to that and keep gas powered generation not running at the full amount.”<\/p>\n\n\n\n

Crudely, Los Angeles can count on solar power generation from 7 a.m. to 7 p.m., said Louis Ting, director of power planning development at the agency. The batteries in this project effectively extend that horizon four hours, to 11 p.m.<\/p>\n\n\n\n

“The battery can be dispatched differently,” Barner added, “depending on the system need. So you could run that four-hour battery over 16 hours at one-fourth of the output, so you can vary it over time. It\u2019s not just fixed over four hours.”<\/p>\n\n\n\n

The plant will be developed by\u00a08minute Solar Energy\u00a0on 2,653 acres of privately-owned land in the Barren Ridge renewable corridor in Kern County. The development was\u00a0first reported Friday by John Weaver at pv magazine, who noted in comments that the price for battery storage is not added on top of the solar price. It’s a separate power product, sold at 1.3\u00a2.<\/p>\n\n\n\n

Barner explained that the plant will be able to generate more solar energy each day than the available transmission capacity. The extra power will be stored.<\/p>\n\n\n\n

“The solar is inherently variable, and the battery is able to take a portion of that solar from that facility, the portion that\u2019s variable, which is usually the top tend of it, take all of that, strip that off and then store it into the battery, so the facility can provide a constant output to the grid. It can turn this solar facility, which is not typically dispatchable, into a dispatchable type of facility.”<\/p>\n\n\n\n

The plant is expected to deliver its first megawatt by April 2023, a timeline that qualifies it for the federal solar investment tax credit.<\/p>\n\n\n\n

“This project is able to make full use of that investment tax credit, which is substantial,” Barner said. “It\u2019s 30 percent that is basically knocked off the capital cost of the project.”<\/p>\n\n\n\n

A natural-gas plant opening that same year would produce power at more than twice the price,\u00a0according to the U.S. Energy Information Agency, or 4\u00a2-4.3\u00a2\/kwh. The agency did not bother modeling the estimated cost of coal or nuclear plants in its 2019 Energy Outlook because, it says, none are expected to be built. Nuclear often benefits from optimistic estimates in the range of\u00a012\u00a2\/kwh. Nuclear’s advantage has been its constancy and reliability, an advantage cheap storage increasingly challenges.<\/p>\n\n\n\n

The lowest known solar price is\u00a01.97\u00a2 for a project in Mexico\u00a0that did not include storage.<\/p>\n\n\n\n

LA is partnering with the city of Glendale on this project, one of eight the staff is negotiating with renewables developers.<\/p>\n\n\n\n

Ratepayer advocate Fred Pickel cautioned commissioners to anticipate even lower prices for energy storage:<\/p>\n\n\n\n

“Seven years ago the first major projects were brought forward to this board. They\u2019re in service now, they\u2019re the ones that are referred to in or near Nevada. And they were between $90 and $100 a megawatt hour or 9 and 10 cents a kilowatt hour. Now we\u2019re seeing solar projects under 2 cents a kilowatt hour. And I think it\u2019s important to keep the speed of that technology change in mind as we think about batteries and other things. We\u2019re placing bets of how quickly we move vs. how quickly the technology might move, and it is helpful to have a diversified approach to this.”<\/p>\n\n\n\n

“Is it your view that this steep price decreases will continue?” asked Commissioner Mel Levine.<\/p>\n\n\n\n

“It\u2019s a gamble,” Pickel said. “You’ve got to know when you’re gambling.”<\/p>\n\n\n\n
