Solar power in California explained

Solar power has been growing rapidly in the U.S. state of California because of high insolation, community support, declining solar costs, and a renewable portfolio standard which requires that 60% of California's electricity come from renewable resources by 2030, with 100% by 2045.[1] Much of this is expected to come from solar power via photovoltaic facilities or concentrated solar power facilities.

At the end of 2023, California had a total of 46,874 MW of solar capacity installed, enough to power 13.9 million homes in the state. California ranked as the highest solar power generating state in the nation, with solar power providing for 28% of the state's electricity generation. The Solar Energy Industries Association predicts that California will increase its solar capacity by over 20,000 MW over the next five years, the second highest increase in solar capacity in the country behind Texas at 41,000 MW.

The state government has created various programs to incentivize and subsidize solar installations, including an exemption from property tax, cash incentives, net metering, streamlined permitting for residential solar, and, in 2020, requiring all new homes have solar panels.

History

Over the last 20 years, California has been home to a number of the world's largest solar facilities, many of which are located in the Mojave Desert. In 1991, the 354 MW Solar Energy Generating Systems plant (located in San Bernardino County, California) held the title until being bested by the 392 MW Ivanpah Solar Electric Generating System, a solar thermal plant located in San Bernardino County near the Nevada border.

The early to mid 2010s saw the sharpest increase in solar development.[2] By the end of 2013, California had 490 MW of concentrated solar power and 5,183 MW of photovoltaics capacity in operation.[3]

In 2014, the 550 MW Topaz Solar Farm became the new "world's largest operational" solar facility and went online in San Luis Obispo County, California. A second 550 MW facility, Desert Sunlight Solar Farm, went online in Riverside County in 2014, constructed by First Solar. In June 2015, the 579 MW Solar Star facility went online, becoming the new largest operational solar facility and making California host to the three largest photovoltaic solar facilities in the world.[4] There are several proposals for even larger facilities seeking regulatory approval in California, such as the 2.7 GW Westlands Solar Park.

In 2014, California led the nation in the number of homes which have solar panels installed, totaling over 230,000.[5] Many were installed because of the Million Solar Roof Initiative.[6]

In December 2017, the Solar on Multifamily Affordable Housing (SOMAH) program was approved by the California Public Utilities Commission. The program plans to allocate one billion dollars from the state's greenhouse gas cap-and-trade program to incentivize owners of affordable, multi-family buildings to install solar, with a goal of adding 300 MW of capacity by 2030.[7]

In May 2018, the California Energy Commission (CEC) required that nearly all new homes (both single-family and multi-family) under four stories be built with rooftop photovoltaic solar panels .[8] Developers can also receive approval from the CEC to subscribe new homes to local community solar generation.[9] In early 2020, the Sacramento Municipal Utility District (SMUD) was approved to provide community solar to new homes in Sacramento.[10] [11] Solar systems with battery storage are now much more valuable than systems without battery storage, mostly because new solar generation exacerbates the duck curve (varying power supply from traditional power plants).[12] Solar production causes fossil-fuel power plants to be turned down to minimum during the day, but when solar production stops in the evening peaker plants must quickly ramp generation by 5GW an hour to supply peak demand.[13] New solar generation only displaces other solar generation and increases the supply ramping needed by peaker plants, which is expensive for utilities.[14] Battery storage systems flatten the duck curve by storing solar and wind energy at non-peak hours and discharging it at peak hours. California's most recent net energy metering policy now incentivizes systems with battery storage more than solar systems with no installed storage.

Housing affordability is also a concern with this measure, an area where California already struggles greatly.[15] According to a 2017 survey conducted by the U.S. Census Bureau, 37.8% of California homeowners with mortgages are "cost-burdened," with housing costs exceeding 30% of the household income, and 16.3% face housing costs exceeding 50% of the household income.[16] The CEC predicts that the requirement of photovoltaic panels will increase the cost of a newly built single-family home by about $40 per month in extra mortgage payments, but eventually save about $80 on electricity costs.[17] The CEC released data showing that the system would more than pay for itself, however charitable organizations such as Habitat for Humanity have expressed their concerns as this will require the organization to receive additional donations to pay for the photovoltaic panels that the group would be required to install on every house it builds.[18]

Photovoltaics

In 2011, California's goal to install 3,000 MW of distributed generation by 2016 was expanded to 12,000 MW by 2020.[19] California has more photovoltaics installed than any other federal state, and 48% of the U.S. total in 2010. For the first time in 2008 the installed photovoltaics exceeded the state's 354 MW of solar thermal (CSP).[20] [21] There are plans to build over 15,000 MW of utility scale photovoltaic plants in California.[22] At the end of 2012, small systems of less than 10 kWp were averaging $5.39/W, and large systems of over 500 kWp were averaging $2.77/W.[23]

California has the technical potential to install 128.9 GW of rooftop solar panels, which would generate 194,000 GWh/year, about 74% of the total electricity used in California in 2013. This is environmentally desirable because it would conserve large swaths of desert by placing panels atop preexisting structures instead. However, this would supply three to four times peak midday demand, requiring output to be stored or exported on sunny days.[24]

Solar thermal power

California has several large concentrated solar power plants.

The Ivanpah Solar Electric Generating System (392 MW), located 40miles southwest of Las Vegas and developed by BrightSource Energy and Bechtel, is the world's largest solar thermal power project.[41] The project has received a $1.375 billion loan guarantee from the United States Department of Energy. It deploys 347,000 heliostat mirrors focusing solar energy on boilers located on centralized solar power towers.[42]

The Genesis Solar Energy Project is an operational 250 MW solar thermal power station located in Riverside County, California. It features a parabolic trough design and is run by NextEra Energy Resources.[43]

Operational

Total operational installed gross power is 1,313 MW (1346 MW until 2014). Production in 2015 was 2,309 GWh, 71.2% of U.S. total solar thermal generation.[44]

Planned

South Belridge Oil Field, near Bakersfield, California, a solar EOR facility that is projected to eliminate 376,000 metric tons of carbon emissions. It was announced in November 2017 as a joint venture between GlassPoint Solar and Aera Energy.[45]

In 2012, the Bureau of Land Management gave priority status to 5 solar project proposals in California.[33] The 750 MW McCoy Solar Energy Project was proposed by NextEra, though only 1/3 of that wattage was ever installed. The remaining development of the project is currently on hold. The 100 MW Desert Harvest project has been proposed by enXco. The 664 MW Calico Solar Energy Project was redesigned by K Power but later abandoned.[46]

Generation

The Energy Information Administration (EIA) provides California electricity generation data from 2001. Below is a table of annual and monthly utility-scale solar generation, including thermal and PV generation, alongside the percentage of total annual CA energy generation and percentage of all US solar generation.

Milestones

On May 13, 2017, the California Independent System Operator (CAISO) reported that the state had broken a new renewable energy record, with non-hydro renewables providing 67.2% of the total electricity on the ISO's grid (13.5% was provided by hydropower). The ISO reported that solar was providing approximately 17.2% of the total electricity.

On March 5, 2018, at around 1:00 pm, utility-scale solar energy met 50% of California's total electrical power demand for the first time.[47]

On May 2, 2022, CAISO reported that California's electrical demand was met 100% by renewable energy sources for the first time. This was maintained for nearly 15 minutes. During this period, 12,391 of the 18,000 megawatts (68.8%) of demand were generated by PV systems alone.[48]

Government support

Exemption from property tax

Since 1980, the state government excluded solar installations as taxable improvements on a property.[49] [50] This has resulted in many counties seeing no tax benefit from solar farm installations, with some like Kern County stating that they had lost $110 million in property taxes over a decade due to this policy.

State legislators felt that the policy was necessary because otherwise the property taxes on solar farms would be four to seven times higher in California than neighboring states, and would thereby incentive all new development of solar to occur out-of-state.

Renewable portfolio standard

California's renewable portfolio standard (RPS) sets a minimum of renewable generation from load-serving entities in the state. The most recent RPS was set under senate bill 100 and went into effect January 1, 2019. SB 100 mandates that 60% of California's electricity will be generated by renewable resources by 2030, and 100% will be generated by carbon-free sources by 2045.[51] Much of this is expected to come from solar power.

According to a report by the California Public Utilities Commission (CPUC), California failed to meet the 20% renewables by 2010 target. In 2010, Southern California Edison produced 19.4% of its electricity from renewable sources, Pacific Gas and Electric Company generated 17.7% of the electricity it sold from renewable sources, and San Diego Gas & Electric generated 11.9% of its electricity from renewable sources.[52]

As of October 2020, California had 31,288 MW[53] of solar and 5,830 MW[54] of wind farms. California adopted feed-in tariffs, a tool similar to what Europe has been using, to encourage the solar power industry. Proposals were raised aiming to create a small-scale solar market in California that brings the benefits of the German market, such as distributed generation, which avoids the need for transmission because power is generated close to where it is used, and avoid the drawbacks such as excessively high payments that could become a burden on utility customers.[55]

California Solar Initiative

The California Solar Initiative is a 2006 initiative to install 3,000 MW of additional solar power by 2016. Included in it is the Million Solar Roof Initiative.[56] In 2011, this goal was expanded to 12,000 MW by 2020.[57] As part of Governor Arnold Schwarzenegger's Million Solar Roofs Program, California has set a goal to create 1,940 megawatts[58] of new, solar-produced electricity by 2016 – moving the state toward a cleaner energy future and helping lower the cost of solar systems for consumers. The California Solar Initiative has "a total budget of $2.167 billion between 2007 and 2016 and a goal to install approximately 1,940 MW of new solar generation capacity."[59]

According to the CPUC, homeowners, businesses, and local governments installed 158 MW of solar photovoltaics (PV) in 2008, doubling the 78 MW installed in 2007, giving California a cumulative total of 441 MW of distributed solar PV systems, the highest in the country. As of August 2016, 4,216 MW have been installed in 537,647 projects. The average cost of systems less than 10 kW is $5.33/watt and $4.38/watt for systems over 10 kW.[60] Of these, 3,391 MW were rooftop solar in 2015.[61]

The CSI initially offered cash incentives on solar PV systems of up to $2.50 per AC watt. These incentives, combined with federal tax incentives, could cover up to 50% of the total cost of a solar system. The incentive program was designed so that the incentives would reduce in steps based on the amount of solar installed in each of 6 categories. There are separate steps for residential and non-residential customers in the territories of each of the State's 3 investor-owned utilities. As of July 2012, the rebates range from $0.20 to $0.35 per AC watt for residential and commercial systems and from $0.70 to $1.10 for systems for non-profits and government entities.[59]

There are many financial incentives to support the use of renewable energy in other US states.[62] CSI provides more than $2 billion worth of incentives to customers for installing photovoltaic,[63] and electricity displacing solar thermal[64] systems in the three California Investor-Owned Utilities service territories.

The program was authorized by the California Public Utilities Commission and by the Senate Bill 1 (SB 1):

Responsibility for administration of the CSI Program is shared by Investor-Owned Utilities:

Residential installation starts in early 2007 fell off sharply in SCE territory because of the disincentives inherent in SB1, requiring time-of-use (TOU) tariffs, with the result that homeowners who install panels may find their electric bill increasing rather than decreasing. The governor and legislature moved quickly to pass AB1714 (June 2007) to delay the implementation of this rule until 2009.

Net metering

See main article: Net metering. California's net energy metering program incentivizes distributed solar generation and battery storage by compensating customers for excess energy they export to the electric grid. A consumer's excess solar generation is bought by the local utility at or below retail pricing when it is exported, allowing consumers to "store" their own generation in the grid to be used at any time.[65]

Net metering was first implemented in 1995 in the passing of Senate Bill (SB) 656, known now as NEM1.

Out of 38 states evaluated in a rating of state net metering policy in 2007, California was one of five states to receive an A.[66] IREC best practices, based on experience, recommends no limits to net metering, individual or aggregate, and perpetual roll over of kWh credits.[67] As California was rapidly approaching the 5% aggregate limit, a May 24, 2012, ruling by the CPUC clarified the calculation of the limit, and requested a report on the cost of net metering.[68] [69] California subsequently uncapped the net metering program.[70] Typically states have raised or eliminated their aggregate limits before they were reached.[71] By 2011, 16 states including California received an A for net metering.[72]

In 2013, Assembly Bill (AB) 327 mandated that a successor to the existing NEM1, NEM2, should be adopted by the CPUC. NEM2 went into effect in SDG&E's service territory on June 29, 2016, PG&E's service territory on December 15, 2016, and SCE's service territory on July 1, 2017.[73] One of NEM2's key objectives was to ensure continued growth of distributed solar by removing the 1,000kW limit on new systems. While NEM2 continued to compensate customers with full retail pricing, it also included three charges: a one-time interconnection fee, non-bypassable charges that fund low-income customers, energy efficiency programming and other energy programs, and a time-of-use (TOU) rate.[74]

California's current net metering policy is outlined in the Net Billing Tariff,[75] known as NEM3, which went into effect April 15th, 2023.[76] The Tariff takes into account proposals from various parties, including a lookback study on NEM 2.0 and 1.0. While in NEM1 and 2 customers received credits for energy exported and deducted those credits when importing electricity from the grid at a nearly 1:1 exchange, under NEM3 energy exports are now valued at the avoided cost to the utility — the wholesale price it takes the utility to produce energy. Credits are typically $0.05 per kWh, but when electricity demand is high it can spike up to $2.87 per kWh.

California's net metering policy was rated 19th by Solar Reviews in 2021, California receives a B only because electricity credits include charges and don't pay at full retail rate but at marginal cost.[77]

Mandatory solar power in new homes

In March 2008, Culver City established the first in the nation mandatory solar photovoltaic requirement, which requires an installation of 1 KW of solar photovoltaic power per of new or major remodeled commercial building area.[78]

In March 2013, Lancaster, California became the first U.S. city to mandate the inclusion of solar panels on new homes, requiring that "every new housing development must average 1 kilowatt per house."[79] In May 2013, Sebastopol followed suit, requiring new buildings include either 2 W/sq ft (21.7 W/m2) of insulated building space of photovoltaics, or enough to provide 75% of the expected annual electricity use.[80]

Since January 1, 2014, California law requires all new buildings less than ten stories tall be "solar ready".[81]

In April 2016, San Francisco mandated that all new buildings less than ten stories tall include solar panels or solar water heating covering at least 15% of the roof, beginning January 1, 2017.[82]

In 2018, the State of California Building Standards Commission approved solar installation requirements for all new residential buildings with three stories or fewer. This requirement took effect in 2020.[83]

Streamlined permitting

California governor Jerry Brown signed a streamlined permitting bill (AB 2188) for residential solar systems on September 22, 2014. AB 2188 has four major provisions designed to reduce red-tape associated with local solar permits and requires that, by the end of September 2015, all California cities and counties must "adopt an ordinance that creates an expedited, streamlined permitting process for residential rooftop solar energy systems of less than 10 kilowatts in size."[84] Research and industry reports project the bill could reduce the cost of installing a typical residential solar system in the state by over $1,000.[85]

Alameda County solar financing

Using a 20-year property assessment known as PACE financing, the city of Berkeley had a successful pilot program from 2008 to 2009 as the first city in the country to allow residents to obtain solar power without any initial payment. In the plan, property owners paid as much in increased property taxes as they save in energy costs, allowing them to install the panels for free at no cost to the city. Thirty eight projects were installed for the pilot stage of the program.[86] PACE financing has spread to 28 states, but is on hold in many due to objections by Freddie Mac and Fannie Mae, including in Berkeley (which has not continued the pilot as a result). Legislation has been introduced to require acceptance of PACE financing.[87]

City of Los Angeles feed-in tariff

The City of Los Angeles Department of Water and Power initiated a program on January 11, 2013, to pay up to 17 cents/kWh for electricity generated by up to 100 MW of solar power in a feed-in tariff program. 20 MW is reserved for small projects of less than 150 kW each. The program could be expanded to 150 MW in March.[88]

State challenges with solar power

Energy storage is becoming a more prominent issue because photovoltaic solar panels can only generate electricity during daylight hours and thermal solar installations can only store energy for up to 10 hours, leaving a window in which the state's energy production must be generated from other sources (natural gas, wind, coal, or nuclear). To remedy this, different sorts of power storage solutions have been proposed such as batteries, compressed air, and ice generation.[89]

In April 2018, The San Diego Union Tribune reported that Recurrent Energy (a subsidiary of Canadian Solar) had proposed a large battery, a 350 MW system, to be installed alongside the proposed Crimson Solar Project. The battery will match the proposed facility's nameplate capacity, and is several times larger than the 130 MW Hornsdale Power Reserve, the largest lithium battery in existence, which was created by Tesla and is located in South Australia.[90]

Another issue is overproduction which is most common during the spring months, when electricity production from wind power is high, but demand from heating and cooling is low.[91] California's solar production was so vast that by 2017, California had to pay Arizona and other states in the region to accept some of its electricity during peak production hours to provide relief to its grid.[92]

California also has aggressive goals when it comes to zero emissions vehicles (ZEVs), and the most prominent type is the electric car, which relies on grid power to charge its battery. Plug-in hybrid cars are also very popular in the state. These types of vehicles add to the demand and burden placed on the electrical grid, which was not designed to support the larger electrical loads required by electric vehicles.[93] One potential solution is to bypass most of the grid with the installation of rooftop solar panels for daytime charging and making use of home energy storage at night. Some electric companies will also provide discounted rates for car owners who charge their vehicles at night when demand is lower. Some cars can be programmed to stagger their charging cycle throughout the night. This leads to a steady rate of charging instead of a large spike in the early evening when most commuters return home.[94]

Public opinion

The majority of Californians in desert country support large-scale solar development, according to a 2012 survey conducted on behalf of BrightSource Energy. The survey of more than 1,000 people was conducted throughout Imperial, Inyo, Kern, Riverside, San Bernardino counties in California, where many utility-scale solar projects are underway or planned. Survey results showed that nearly four out of five (almost 80 percent) people strongly supported development of solar power in their communities. The survey also found that the majority of people were concerned with climate change. It also found that two-thirds of respondents think renewable energy is important to California's future and that the state and federal government should help provide incentives for renewable energy projects.[95]
