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.

Solar Panels at Data Center to Save State Millions

By News Staff, Techwire

The California Department of Technology and the Department of General Services are touting the energy efficiency and resulting savings from a solar canopy in the parking lot of the state’s main data center in Rancho Cordova. The solar panels, which feed the data center, have been in place for about a year, according to a blog post on CDT’s website.

“Since its completion in September 2018, the 76,000-square-foot solar canopy, located at CDT’s Gold Camp Data Center facility in Rancho Cordova, has generated more than 1 million kilowatt hours of electricity and is on track to double that amount annually,” says the blog post. “The energy generation will account for about 10 percent of the facility’s annual electrical demand while reducing nearly 10 tons of greenhouse gas emissions.”

The energy produced on a typical summer day from the “green” structure, which covers 316 parking spaces, can reach 1 megawatt of power per hour — enough to power 164 homes, according to CDT.

Opinion: An uncertain path to a cleaner future – Zero carbon electricity legislation in New York and California

By Thomas R. Brill & Steven C. Russo (Greenberg Traurig), Utility Dive

Last month, New York passed the Climate Leadership and Community Protection Act, which calls for a carbon free electricity market by 2040. With passage of this law, New York became the sixth state to pass legislation calling for a carbon free electricity market. Just one year earlier, California passed similar legislation, SB100, adopting a state policy to achieve a zero-carbon electricity market by 2045.

These goals will have to be pursued notwithstanding the fact demand for electricity is projected to increase as other sectors pursue beneficial electrification to comply with ambitious emission reduction goals they face. Whether these goals can be achieved, and at what cost, will depend on technology advancements and how these laws are interpreted and implemented by regulators.

New York’s Climate Leadership and Community Protection Act requires 70% of electricity consumed in New York be generated by renewable resources by 2030 and the state must be carbon free by 2040. California’s SB100 requires 60% of electricity come from renewable resources by 2030 and adopts a state policy of a 100% zero carbon electricity by 2045.

The New York legislation explicitly conditions meeting these extraordinarily ambitious renewable energy mandates on maintaining reliability and affordability. This leads to obvious questions: Can a zero-carbon electricity market be achieved in a manner that maintains reliability and affordability, and if so, how? What flexibility exists under these laws to ensure these emission reduction goals can be achieved even if new technologies or significant price declines fail to materialize?

Solar is coming to all new California homes. How many in Fresno already get power from sun?

By Tim Sheehan, The Fresno Bee

More than 1 million California homes are already soaking up sunshine with solar panels to generate electricity. Next year, that number will surge as new building standards take effect requiring all new homes permitted after Jan. 1 to have solar photovoltaic systems.

In Fresno, which already has the third-highest number of homes in California with rooftop solar panels, the number continues to grow even before the new California Energy Commission standards take full effect. Through the first six months of 2019, the city issued permits for more than 1,640 residential solar systems as additions or alterations to existing homes. That doesn’t count solar panels that home builders or developers are already offering as a feature on new homes.

As of June 30, more than 23,300 Fresno homes had solar systems in operation under the state’s Net Energy Metering (NEM) program. That’s third behind only San Diego and Bakersfield among California cities, according to data from Go Solar California. The total electrical output capacity of Fresno’s residential solar panel systems amounted to almost 148,700 kilowatts of direct current (DC) power. That’s about 144,000 kilowatts of alternating current or AC electricity after it’s converted from DC.

Fresno also has another 1,742 homes with solar installed from 2007 through 2017 under the older California Solar Initiative program.

The $2.5 trillion reason we can’t rely on batteries to clean up the grid

By James Temple, MIT Technology Review

A pair of 500-foot smokestacks rise from a natural-gas power plant on the harbor of Moss Landing, California, casting an industrial pall over the pretty seaside town. If state regulators sign off, however, it could be the site of the world’s largest lithium-ion battery project by late 2020, helping to balance fluctuating wind and solar energy on the California grid.

The 300-megawatt facility is one of four giant lithium-ion storage projects that Pacific Gas and Electric, California’s largest utility, asked the California Public Utilities Commission to approve in late June. Collectively, they would add enough storage capacity to the grid to supply about 2,700 homes for a month (or to store about .0009 percent of the electricity the state uses each year).

The California projects are among a growing number of efforts around the world, including Tesla’s 100-megawatt battery array in South Australia, to build ever larger lithium-ion storage systems as prices decline and renewable generation increases. They’re fueling growing optimism that these giant batteries will allow wind and solar power to displace a growing share of fossil-fuel plants.

But there’s a problem with this rosy scenario. These batteries are far too expensive and don’t last nearly long enough, limiting the role they can play on the grid, experts say. If we plan to rely on them for massive amounts of storage as more renewables come online—rather than turning to a broader mix of low-carbon sources like nuclear and natural gas with carbon capture technology—we could be headed down a dangerously unaffordable path.

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.

Solar is Generation of Choice in California

By Robert Mullin, RTO Insider

California’s second-largest publicly owned utility is “not buying anything other than solar right now,” said Arlen Orchard, CEO of Sacramento Municipal Utility District (SMUD). Orchard’s comment reflected prevailing opinion at the Infocast California Energy Summit last week: Solar is the generation of choice now in California — and its role will only grow.

For SMUD, the decision to go with solar is a financial one. Despite historically low natural gas prices, California’s environmental mandates — such as emissions caps and a ban on once-through cooling — make investment in even the most efficient new gas-fired generation less attractive than solar, even in the resource-constrained Los Angeles basin. “It sounds like for a lot of reasons, building more gas-fired generation in L.A. is not going to happen,” said Charles Adamson, principal manager with Southern California Edison, also pointing out the political unpopularity of building new gas generation in the state.

In Northern California, the alternatives to solar are other — more expensive — renewable resources. “Solar was once the most expensive — now it’s the lowest cost,” said Jan Smutny-Jones, CEO of the Independent Energy Producers Association, whose membership includes gas-fired and renewable merchant generators.

Declining solar costs are attracting the interest of more than just traditional utilities, according to Mark Fillinger, director of project development for First Solar. California’s investor-owned utilities have effectively met the state’s 33% by 2020 renewable portfolio standard. Fillinger said his company is now seeing a “huge shift” in demand from those customers to large “direct access” commercial and industrial clients who choose to purchase power from an independent electricity supplier rather than a regulated utility.

California Has Too Much Solar Power — And That’s a Good Thing

By Travis Hoium, The Motley Fool

No business wants to create a solution in search of a problem, particularly in the slow-changing energy industry. Instead, businesses want to find solutions for problems that exist and create ways to make money off their solutions.

Enter the exigent problem California is facing: it has too much solar energy. First, who thought that would be a problem in the country’s largest state? Second, why isn’t there a solution if utilities and regulators knew this problem was coming? The short answer is that energy innovators weren’t going to create and install solutions for solar energy’s variability until they knew the utilities and regulators had recognized the problem.

California has made a big push into renewable energy in an effort to meet a 50% renewable energy goal by 2030. It’s built wind and solar plants rapidly over the past decade, which combines with hydropower to provide clean energy to the state. The problem is that solar energy, in particular, isn’t created evenly throughout the day or year and that’s a challenge for the grid.

In March, before peak air conditioner season in the state, there was so much solar energy on the grid that the California Independent System Operator had to tell some solar farms to shut down because there was too much energy for the grid to handle. And that could lead to a blackout.

Utility-Scale Solar Surpasses Wind in California for First Time in 2015

Recent analysis from Vaisala, a global leader in environmental and industrial measurement, reveals that in 2015 energy from grid-connected, utility-scale solar plants surpassed wind for the first time in California. While this is an exciting milestone for the solar industry, the rise of solar also brings with it a demand for better forecasting information to cope with the challenges that the increase in variable generation poses to the regional energy system.

California has been a national leader in renewables since first establishing its Renewable Portfolio Standard (RPS) in 2002, and, with a 50% RPS mandate recently signed into law, it is likely to maintain its position for years to come. Today the state is still one of the largest U.S. wind markets in terms of capacity, but the exponential growth of large-scale solar in recent years has considerably altered the structure of the regional energy market.

Public records from CAISO (California Independent System Operator) indicate that over the past five years, grid-connected, utility-scale solar generation in California increased fifteen-fold. It went from a total of 1,000 GWh in 2011 to an impressive 15,592 GWh in 2015, composing 6.7% of the system total and surpassing wind for the first time, which made up 5.3% of the system total.
