Los Angeles’s Low-Priced Solar Power Has Problems Coming Its Way

By Cassie McCorkle, Energy Industry Reports

It has been more than a month that Los Angeles has signed a contract for record-cheap solar power and the officials are trying to deny it. The labor union is concerned over Mayor Eric Garcetti’s decision to put an end to the three gas-fired power plants. It has been clearly mentioned in the 25-year contract signed with 8minute Solar Energy that the Los Angeles Department of Water and Power will pay 2 cents per kilowatt-hour or lower. This is the lowest price ever waged for solar power in the US and it is lower than the cost of electricity generated from the natural gas-fired power plant. The Eland project has 200 Megawatts of lithium-ion batteries planned other than the 400 Megawatts of solar power to store solar power for a complete day and to let it into the grid for 4 Hours each night.

The combined payment of L.A. payers for solar power could be 3.3 cents per kilowatt-hour. The concerns of the International Brotherhood of Electrical Workers Local 18 have forced the City Council to not approve the contract. IBEW Local 18 is concerned that Garcetti’s “Green New Deal” initiative has shutdown 3 coastal gas plants and would result in unemployment of 400 LADWP workers. The workers consider Garcetti’s plans to create unemployment and increase electricity prices. Others may consider the current plan as a childlike proposal but as per the Mayor, the Eland project may not replace the large plants instead can help reduce the dependency on gas. The pricing of 8minute that relies on the federal investment tax credit for solar energy is expected to drop by 26% by this year end. By December, the company plans to start construction to be eligible for the 30% tax credit.

Similarly, a 500 MW project is on its way to construction, as per the Kern County Board of Supervisors. This new project is the one more addition to the long list of large projects taking place in California. This project is a part of the Eland 1 Solar Project: 8minutenergy. The project will be started only after the Eland 1 Solar is approved.

LA & 8Minute Solar ink lowest cost solar-plus-storage deal in U.S. history

By Steve Hanley, CleanTechnica

The Los Angeles Department of Water and Power has signed a groundbreaking 25-year power purchase agreement with 8Minute Solar. The deal will make possible the largest municipal solar plus storage facility in the US. But the best part is the combined price for solar energy plus storage is just 3.3 cents per kilowatt-hour, the lowest ever in the US and cheaper than electricity from a natural gas powered generating plant.

The electricity will come from a massive solar power plant located on 2000 acres of undeveloped desert in Kern County, just 70 miles from the city. Known as the Eland Solar and Storage Center, it will be built in two stages of 200 MW each, with the first coming online in 2022 and the second phase scheduled to be switched on the following year.

Los Angeles DWP will take 375 MWac of solar power coupled with 385.5 MW/1,150 MWh of energy storage, according to PV Magazine. Neighboring Glendale Water and Power will take 25 MWac of solar plus 12.5 MW/50 MWh of energy. The electricity from Eland I and II is expected to meet between 6 and 7% of Los Angeles’ needs, according to PV Magazine.

The Eland Solar & Storage Center has been engineered by 8minute to provide fully dispatchable power under control of the LADWP to meet its customers’ demands with reliable and cost-effective power — a capability previously reserved for large fossil fuel power plants. Eland’s ability to provide fully dispatchable power for less than the traditional cost of fossil fuels effectively positions solar PV as an attractive candidate to be the primary source of California’s 100% clean energy future.

PG&E Free: Revolutionary Energy at Stone Edge Farm in Sonoma, California

By Jonah Raskin, CounterPunch

Pacific Gas & Electric has never had many loyal friends, not since 1905 when the San Francisco Gas and Electric Company and the California Gas and Electric Corporation merged to form the utility giant usually referred to as PG&E.

The company has been increasingly unpopular ever since gas leaks led to a big explosion and the death of consumers— eight people in San Bruno just south of San Francisco. Nor has the company made new friends ever since its power lines were found to have caused wild fires and huge property losses in California.

Earlier this year—to protect its profits and stockholders— the company filed for bankruptcy, though it still has citizens in a chokehold otherwise known as a monopoly. If consumers want electricity and gas in their homes and businesses they have little choice but to rely on PG&E, which owns and controls the power lines.

There are alternatives, including Sonoma Clean Power that sources clean energy from renewables: geothermal, water, wind, solar, and biomass. But Sonoma Clean Power doesn’t have its own power lines. PG&E has said it will cut off all power if and when there’s wild fire and high winds. That could save lives and protect property, but it also sounds like PG&E letting Californians know that it’s still the all-powerful boss.

With big bucks, access to the latest technology and technological wizards, citizens can by-pass PG&E. That’s what Mac and Leslie McQuown have done at Stone Edge Farm, a model of organic agriculture and a center for innovation in the field of energy. The farm is on Carriger Road, outside the town of Sonoma, where olives and grapes are grown. Not long ago, the visionary McQuowns had a big dream: reduce their carbon footprint. They’ve realized that dream and gone beyond it. Now, Stone Edge generates electrical power on a micro-grid that serves all its energy needs.

Los Angeles has lined up record-cheap solar power. But there’s a problem

By Sammy Roth, Los Angeles Times

Los Angeles has been sitting on a contract for record-cheap solar power for more than a month — and city officials declined to approve it Tuesday because of concerns raised by the city-run utility’s labor union, which is still fuming over Mayor Eric Garcetti’s decision to shut down three gas-fired power plants.

Under the 25-year contract with developer 8minute Solar Energy, the Los Angeles Department of Water and Power would pay less than 2 cents per kilowatt-hour — a number city officials and independent experts say would be the lowest price ever paid for solar power in the United States, and cheaper than the cost of electricity from a typical natural gas-fired power plant.

In addition to 400 megawatts of solar power, the Eland project would include at least 200 megawatts of lithium-ion batteries, capable of storing solar power during the day and injecting it into the grid for four hours each night. The combined price to L.A. ratepayers of the solar and storage would be 3.3 cents per kilowatt-hour — also a record low for this type of contract.

But LADWP’s Board of Commissioners voted not to send the contract to the City Council for approval, after utility staff said concerns had been raised by the International Brotherhood of Electrical Workers Local 18, which represents utility employees. In recent months, IBEW Local 18 has run television and radio ads attacking Garcetti’s Green New Deal initiative, which includes the retirement of three coastal gas plants that employ more than 400 LADWP workers.

…The Eland project, which is planned for the Mojave Desert north of Los Angeles, wouldn’t replace those gas plants. But it could help L.A. reduce its reliance on gas, which has become California’s largest electricity source as utilities look for evening power sources to fill in for solar after the sun goes down.

California solar plus storage shows consistent installs, residential growth

By John Weaver, pv magazine

The California Solar & Storage Association (CALSSA) has collected and shared data on California’s behind the meter solar+storage activity in the first half of 2019, with data that goes back to the beginning of 2016.

The data suggests that within the three main investor owned utilities – San Diego Gas & Electric, Southern California Edison and Pacific Gas & Electric – commercial interconnections are running slightly behind the 2018 numbers in terms of projects interconnected. However, residential systems seem to be picking up a bit. 

One chart that gives a bit of indigestion is the time for approval for stand alone and solar+storage installations – if only because of the high variance, but also because quite a few larger projects take more than a year to get approved. The projects are divided into residential, commercial, education and industrial with time frames ranging roughly from 30 to 60 days for residential, to two years for industrial systems. Adding solar power to a storage installation seems to speed up the amount of time for a residential installation, however, it slows a commercial installation.

In Pacific Gas & Electric territory 20% of residential energy storage systems are stand alone, while in the other territories solar is coupled with storage 99-100% of time. Commercial installations had an inverse relationship though – with only 40% of storage projects coupled with solar power, suggesting the market is being driven by other factors like demand charges.

Distributed residential solar+storage takes a seat at the adult table

By John Weaver, pv magazine

We should thank Sunrun for continuing to break new ground, and for investing company resources in moving the industry forward. Now the industry has a new precedent that it will build upon; it has a piece of confidence to carry. And residential solar+storage is soon to be a fundamental building block of the Eastern Interconnection – argued to be the largest machine on the planet.

Sunrun has won a bid for 20 MW to participate in ISO New England’s 2022-2023 Forward Capacity Market. The bid means that Sunrun will be required to offer to the broader power grid 20 MW of power, 24 hours day for the single year period. The company will be paid $3.80/kW/month – totaling $76,000/mo, and $912,000 for the full year contract.

Sunrun notes that the capacity will be made possible by its Brightbox energy storage product line. Currently, this product is an LG Chem RESU. LG’s 48-volt battery comes with 3.3, 6.5 and 9.8 kilowatt-hour (kWh) ratings, and its 400-volt batteries offer 7.0 and 9.8 kWh ratings. Both AC- and DC-coupled versions are available. Sunrun noted they would need about 5,000 New England customers to meet the requirement – which would suggest somewhere between.

…This announcement comes of the heels of two very significant recent legislative victories for solar+storage. First, California is allowing DC coupled solar+storage to participate in net metering. And second, Massachusetts just ruled that energy storage that is in the SMART program has the right to sell its own energy into these same forward capacity markets that Sunrun just bid on. Sunrun was part of the negotiations with Massachusetts to push this legislation through.

Brown Signs “Sun Shine at Night” Bill

Sacramento – With the Global Climate Action Summit in the rearview mirror, California Governor Jerry Brown signed into law SB 700 by Senator Scott Wiener (D-SF) keeping California in the driver’s seat of building a reliable and safe clean energy future.

“If we are going to get to 100% clean energy, we need to be using solar power every hour of the day, not just when the sun is shining,” said Senator Scott Wiener, author of SB 700. “This bill will protect clean energy jobs while also protecting consumers from ever rising energy bills.”

SB 700 will make the “sun shine at night” through the addition of hundreds of thousands of energy storage devices and batteries connected to hundreds of thousands of solar panels over the next 8-10 years. Energy storage is a critical technological partner in the widescale deployment of renewable energy. SB 700 will result in nearly three gigawatts of energy storage systems at schools, farms, homes, nonprofits and businesses in California by 2026 that will benefit consumers, ratepayers and the environment. The resulting program would be on par with the highly successful Million Solar Roofs Initiative launched back in 2006.

SB 700 re-authorizes the Self-Generation Incentive Program (SGIP) for five years, extending rebates for consumers through 2025. It would add up to $800 million for storage and other emerging clean energy technologies, resulting in a total investment of $1.2 billion for customer sited energy storage. Boosting energy storage will help California achieve its goal of generating 100% of its electricity from renewable resources, as called for in SB 100 (de Leon), which was signed into law on September 10th. A summary of SB 700 with more details about the SGIP program can be found here.

Fresno Unified School District and ForeFront Power commence construction of 8.2 MW solar-plus-storage portfolio across 8 sites

ForeFront Power and Fresno Unified School District (“Fresno USD”) are thrilled to announce the groundbreaking of 8.2 megawatts (MW) of solar parking canopy systems across 8 District facilities. The portfolio of projects, which includes intelligent energy storage solutions provided by Stem Inc., is expected to save Fresno USD over $27 million over 20 years.

Fresno USD partnered with ForeFront Power after a rigorously competitive solicitation. In Fall 2017, School Project for Utility Rate Reduction (SPURR) and Fresno USD conducted a statewide request for proposal process to select the best solar and energy storage provider. The comprehensive procurement process through SPURR enabled the District to save considerable time, money, and resources in their procurement process.

Construction of the solar canopy systems is underway at Bullard, Fresno, Roosevelt, and McLane High Schools with the remaining four sites (Edison, Hoover, and Sunnyside High Schools and Service Center) breaking ground in the coming weeks. These 8 solar projects are expected to offset the equivalent of 10,633 tons of carbon dioxide avoidance annually or 2,000 cars taken off the road for the first year of production.

Boosting battery storage can lower utility bills — study

By Daniel Cusick, Environment & Energy Publishing

Adding energy storage to an already robust solar market in California’s multifamily housing sector could lead to significant utility bill savings for building owners and tenants, new findings from the Clean Energy Group and partner organizations show.

In a new 50-page analysis released last week, CEG, along with the California Housing Partnership Corp. and Center for Sustainable Energy, found that lower-income apartments provide a ripe opportunity for developers to improve the economics of solar by adding battery storage to such apartment buildings. “It essentially creates a new pool of savings, so if you were only doing efficiency and only doing solar, you’d get some savings. But if you add storage, you get significantly more,” said Lewis Milford, CEG’s president and a co-author of the report, “Closing the California Clean Energy Divide.”

The authors say the findings are especially relevant in light of California’s recent passage into law of the Multifamily Affordable Housing Solar Roofs Program, a $1 billion investment program to deploy solar technologies in affordable multifamily rental housing that is expected to extend the benefits of solar power to hundreds of thousands of lower-income Californians.

But solar access by itself isn’t enough, the report says. In fact, shifting policies around rooftop solar in some states, including California, could place owners and tenants of low-income housing at greater risk because the benefits of solar are highly dependent on strong net-metering programs. A number of states have reformed net metering in ways that sharply curtail the benefits of solar, resulting in higher, not lower, electricity bills.

Battery storage effectively reduces that risk, the authors say, by eliminating most of the demand-related charges that utilities pass along to owners of distributed energy systems like rooftop solar.

“Because batteries empower owners of solar PV systems to take control of the energy they produce and when they consume it, storage can deliver deeper cost reductions that can be shared among affordable housing owners, developers, and tenants,” the report states. And unlike stand-alone solar projects, which do little to offset demand-related charges, a properly sized solar system with storage can eliminate nearly all electricity expenses, resulting in an annual electric utility bill of less than a few hundred dollars in some cases.
