Ukiah Utilities offers a PV Buydown Program through the City of Ukiah Electric Department. Commercial and residential customers alike are eligible for a $0.28-per-watt AC rebate after installing a qualifying grid-connected PV system up to a maximum system size of 1 MW. Pursuant to SB1, this incentive decreases annually, beginning July 1, over the 10-year life of the program. The incentive is available on a first-come, first-served basis. Total incentives are capped at $7000 for each residential installation and $25,000 for every commercial installation.

The Electric Program Investment Charge Program (EPIC) is California's public benefits fund. The program invests over $130 million into renewable energy research and development every year. Along with expanding the use of renewable energy, funding is used to advance electric technologies, support local economies and businesses, and improve the health and comfort of local communities. The California Public Utilities Commission (CPUC) oversees energy efficiency funding. The CPUC approves plans for efficiency programs every year. Pacific Gas & Electric (PG&E), Southern California Edison (SCE), Southern California Gas Company (SCGC), and San Diego Gas & Electric (SDG&E) are the four investor-owned utilities that receive funding for efficiency programs.

To be eligible for the sales and use tax exclusion (STE), the property must be used to design, manufacture, produce, or assemble advanced transportation technology or alternative source products or systems. Electric vehicle, electric vehicle battery, and solar photovoltaic manufacturing have been approved for financial assistance. Other approved applications include entities involved in landfill gas and biogas capture and production, demonstration hydrogen fuel production, and biomass processing and fuel production. To be recommended to the CAEATFA Board for approval, applications must be fiscally and environmentally beneficial. Application fees range between $250 and $10,000, and administrative fees range between $15,000 and $350,000. Both are based on the total purchase price.

San Diego, California adopted a Sustainable Building policy when it passed Council Policy 900-14 into law. The policy specifically regulates building measures, private-sector incentives, health and resource conservation, outreach and education, and implementation. Among the several directives introduced, the most notable is a commitment to LEED Certification for all newly constructed city facilities and major renovation projects. Council Policy 900-14 stipulates that all newly purposed City facilities shall incorporate a minimum of 15% self-generation using renewable technologies. This policy shall be applicable only after a reasonable payback in energy cost savings can be demonstrated.

Savings by Design is a program that operates in conjunction with the California Department of Public Utilities. It was established to incentivize builders and owners of commercial buildings to increase energy performance and efficiency. To participate, the project must qualify as a non-residential new construction or renovation project in the service area of one of the six participating utilities within California. To determine funding eligibility, interested prospective participants should contact their respective utility as early on in the design process as feasible. Complete, up-to-date details can be found on the program’s website.

In December of 2005, California governor Arnold Schwarzenegger established a statewide Green Building Action Plan by executive order. Under the order, all new state buildings constructed up to 2025 must meet a minimum LEED certification of Silver, make use of ENERGY STAR certified products, including solar PV and water heating, and meet state energy savings standards. Existing builidngs should comply with the state standards at minimum. By 2025, at least half of existing buildings should be in remodeling to achieve "energy net-zero" in addition to fulfilling LEED Silver minimum requirements. Beginning in 2025, all new state buildings and large-scale remodeling projects must be "energy net-zero" in addition to fulfilling LEED Silver minimum requirements.

The California Building Standards Commission (BSC), since 1989, has published triennial editions of its code that is often referred to as Title 24. In 2008, the BSC approved its first statewide voluntary building code. Two years later, in 2010, a final version of this code was adopted. Parts of this code became mandatory, effective January 2011, and is presently referred to as CalGreen. The latest edition of Title 24 from 2017 stands alongside CalGreen and incorporates critical updates in a section called the Building Energy Efficiency Standards. BSC standards are continuously being amended. The most notable among those modifications include a mandate that all new low-rise homes install photovoltaic (PV) equipment with an annual output greater than or equal to the home's annual electrical consumption.

This property tax exclusion is reserved for those who install solar energy systems before 2024. New buildings, even if going unused, are included in this exclusion. Solar energy systems eligible for this exclusion are those used to collect, store, or distribute solar energy. This includes photovoltaic systems, solar thermal electric systems, solar space conditioning systems, solar water heating systems, solar process heating systems, active solar energy systems, and solar mechanical energy. Also included (at least partially) are storage devices, power conditioning equipment, transfer equipment, pipes, ducts, and dual-use equipment for solar-electric systems. Solar heating systems for pools and hot tubs are ineligible systems.

Homeowners in Western Riverside Council of Governments (WRCOG) participating jurisdictions may get financing for energy and water efficiency projects through the Home Energy Renovation Opportunity (HERO) Program. Financing is repaid through special assessments on property taxes, and the property tax assessment remains with the property in most cases. Only energy and water efficiency products that are permanently attached to the property qualify. Objects like light bulbs and appliances do not qualify. Contractors who are registered with the HERO program can install the equipment. Homeowners could also install the equipment themselves, but they must first sign a Self-Install Agreement with the program.

State law allows the city of Sebastopol to require the creation of solar easements in subdivision projects. This is to assure that solar energy systems receive the necessary sunlight. The city can also put restrictions on buildings and vegetation that interfere with the harvesting of direct sunlight. Sebastopol can require solar easements. Terms of the easement are set by city planners upon approval of parcel maps. Condominium projects that subdivide airspace in existing buildings are exempt from solar easements.

The California Energy Commission offers institutions in the public sector low-interest loan programs for energy efficiency and energy generation projects. Renewable energy generation, combined-heat-and-power energy generation, and thermal energy storage projects are eligible. Some approved projects are upgrades to lighting systems, installment of LED traffic signals, installment of insulation, and purchase of water and wastewater treatment equipment. The maximum loan amount is $3 million to be repaid within a maximum of 17 years. The Commission offers a zero-interest loan to public schools, charter schools, state special schools, and country offices of education. A 1% interest loan is available for cities, counties, special districts, public colleges, community colleges, and public hospitals. Residential, commercial, and private nonprofit institutions are ineligible.

The state of California provides farmers the opportunity to save thousands of dollars through partial sales and use tax exemptions for the purchase of solar energy systems that generate electricity for agricultural purposes. At least 50 percent of the solar power must be used to produce and harvest agricultural products. Farmers must support their claims by documenting the use of the solar power system, ensuring that the energy generated is primarily used for agricultural activities. (Data from the meters on the farm equipment and machinery serves as documentation.)

In 2017, the Executive Director of the CPUC declared in a letter to the IOUs that the US District Court Re-Mat program violated the Supremacy Clause of the US Constitution by mandating numerical limits on utility obligations to purchase power from QFs at a price that differed from the utility’s avoided cost. As a result, all new Re-MAT contracts were suspended pending further CPUC action. The Re-MAT intended to aid the utilities in meeting California's Renewable Portfolio Standard (RPS), to include all the green attributes associated with the energy along with Renewable Energy Credits (RECs) transfer to the utility with the sale. If a real property owner patronizes a publicly-owned utility with 75,000 customers or more, they are encouraged to contact their local utility for further details. Investor-owned utilities can reach out to their respective program administrator for more information.

The Single-Family Affordable Solar Housing (SASH) Program is designed to help low-income, single-family homeowners access solar technology. The program also helps to educate families on the benefits of solar technology and provide green-jobs training by allowing trainees to participate in the installations. The California Solar Initiative funds are partially reserved for households in Investor Owned Utility (IOU) service territories. Low-income families enrolled in the program are provided with up-front incentives for solar system installations. Based on incentive dollars, the SASH program in the PG&E and SDG&E utility territories have been fully reserved. Both territories are closed to any new applications.

The Contractors State License Board is solely responsible for administering contractor licenses in California. This state-specific licensure covering active solar water and space heating systems, solar pool heating systems, and photovoltaic systems is called the C-46 Solar Contractor license. License requirements affirm that prospective contractors must have accumulated four years of relevant experience in addition to passing a state-accredited business and law exam along with the trade exam. While there are no education requirements, there are numerous independent license exam preparation schools throughout California. Once the C-46 requirements are met, contractors are eligible for several other solar contractors license classifications such as General Engineering, General Building, Plumbing, Electrical, and Boiler, Hot Water Heating, and Steam Fitting for solar thermal systems. A comprehensive resource guide to becoming a contractor is published on California's State Contractors Licensing Board website.

Santa Clara, California was the first municipality in the nation to establish solar utility. In 1975, under its Solar Water Heating Program and Sewer Utilities Department Santa Clara began supplying, installing, and maintaining solar water heating systems on behalf of its businesses and residents. As the initiative progressed, the city install solar energy power devices in several of its own facilities. All hardware supplied by the city is maintained under a monthly utility fee and a rental agreement after the lessee pays the initial setup fee. The monthly service charges are determined by the number of solar panels in use.

Lancaster, California became the first US municipality to require the installation of photovoltaics (PV) on all newly constructed homes. Each residential dwelling with a building permit issued on January 1, 2014, or later is required to have a specified amount of PV installed. The size requirements of the system vary according to factors such as zone and lot type. For homes contained with a production subdivision, not every home is required to have a PV system. The builder, however, must meet aggregate PV requirements established for the subdivision. Alternately, if homebuilders will meet PV requirements if they provide evidence that they purchased off-site solar renewable energy credits (SRECs) from a system located within Lancaster.

In 2017, the Executive Director of the CPUC declared in a letter to the IOUs that the US District Court Re-Mat program violated the Supremacy Clause of the US Constitution by mandating numerical limits on utility obligations to purchase power from QFs at a price that differed from the utility’s avoided cost. As a result, all new Re-MAT contracts were suspended pending further CPUC action. The Re-MAT intended to aid the utilities in meeting California's Renewable Portfolio Standard (RPS), to include all the green attributes associated with the energy along with Renewable Energy Credits (RECs) transfer to the utility with the sale. If a real property owner patronizes a publicly-owned utility with 75,000 customers or more, they are encouraged to contact their local utility for further details. Investor-owned utilities can reach out to their respective program administrator for more information.

State Senate Bill 1 of 2006 established the California Solar Initiative and mandated the California Energy Commission (CEC) to create a set of regulations that require sellers of production homes to present solar energy options to all prospective homebuyers. All home sellers must disclose the total installed cost of the solar option presented for all homes located within a subdivision for which a tentative subdivision map has been deemed complete on or after January 1, 2011. Sellers of these newly constructed homes must also disclose where to access information about California solar incentives on the Go Solar California website. Homebuyers may elect into an offset program to install a solar system elsewhere that is equivalent to the aggregate capacity of solar if at least 20% of the buyers within the affected subdivision have opted into the solar option.

In September 2008, San Francisco introduced green building code mandates for new construction projects. These ordinates established a strict set of standards for both commercial and residential dwellings. All applications for new buildings must include detailed documentation concerning how the builder aims to achieve LEED Certification. Additionally, buildings must adhere to a series of GreenPoint rated guidelines, depending on the type of structure, and demonstrate that the required GreenPoint rating can be achieved. Owners of commercial buildings are subject to energy audits every five years, the findings of which must be submitted to the Department of Environment. Some aspects of this report will be made public.

The Green Building Council is a non-profit organization responsible for developing the Leadership in Energy and Environmental Design (LEED) Green Building Rating System. LEED was designed to better facilitate the accurate distribution of incentives to builders that commit to green construction practices. The LEED system is based upon a five-point rating scale for new commercial construction or substantial commercial renovation projects. Incentives are granted on a first-come, first-served basis. Interested applicants are encouraged to consult the US Green Building Council website for further details.

Resolution 62284 was effectuated on November 18, 2003, by the Berkeley City Council. The resolution required that all city-sponsored projects purposed after January 1, 2004, must meet a minimum LEED certification rating. The resolution was amended to require that all city-sponsored projects must meet a minimum of a LEED Silver rating on or after January 1, 2006. The resolution applies to only new construction or renovation projects funded by the city or located on city-owned land of 5,000 square feet, which have a construction estimate of $200,000 or more. This construction estimate shall be based on the value of the dollar in 2003. While LEED points are encouraged whenever possible, buildings deemed historic under any federal, state, or local law can be excepted under the resolution. Projects that can prove an unreasonable burden on the construction plan or the City Department may also be exempt.

The San Diego County Board of Supervisors introduced a specified set of construction design standards for its county facilities and property. The policy requires that every newly constructed county building or major renovation must achieve a US Green Building Council (USGBC) LEED Building Certification. Attaining the lowest EUI (Energy Use Intensity) possible within the client's program and project's budget is a requirement for all purposed county projects. All new constructions controlled by the county are likewise required to exceed the current California Energy Code Title 24 by at least 20%.

It’s a requirement within the municipality of Fresno that all newly constructed buildings owned by the city greater than 7500 square feet must necessarily include an alternative design that supports the installation of a solar energy system. A detailed biannual report specifying compliance to this plan must be demonstrated to the council for each new award of contract. Fresno city council may exempt buildings from this plan should more economical alternatives be available.

A wide range of incentives to increase the energy efficiency of their facilities are available to Sacramento residents through Sacramento Municipal Utility District (SMUD). To this end, four separate rebate programs are offered by SMUD. Express Solutions among them, it’s a program meant for customers who already know which energy upgrades they want to install. Complete Energy Solutions, conversely, is for customers still in the exploratory phase of their energy efficiency solutions. Large industrial projects are eligible for the Custom Incentives program. New constructions are directed by the Savings by Design Program. Additional details are discoverable on the program’s website.

Both prescriptive and custom incentives are available to non-residential customers through the Los Angeles Department of Water and Power. The incentives are meant to encourage energy-efficient upgrades to non-residential facilities through the installation of energy-saving devices, equipment, or systems that exceed Title 24 or minimum industry standards. Estimation software determines the energy savings for each project and, thusly, the custom incentive amount. Los Angeles Department of Water and Power should be contacted before beginning any potentially qualifying project.

In April 2016, The California Public Utilities Commission (CPUC) established a set of rules for net metering PV systems specifically paired with storage devices. The law has endured numerous amendments since it was introduced. Making use of CPUC-approved tools, utilities must establish monthly maximum allowable output limits for net metering facilities. Energy exports from the customer's system exceeding the monthly limit are ineligible for net metering. Publicly-owned electric utilities are exempt if they serve more than 750,000 customers and also provide water services.

Resolution R-298001 is a San Diego resolution that amended the city’s Sustainable Building Policy in 2002 to allow for the expediting of sustainable building permits. The definition of a sustainable building for these purposes can be found under Policy Number 900-14 whereas the permit expediting program is discoverable in Policy Number 600-27. The Sustainable Building Policy is revised triennially. No new residential, commercial, or industrial development projects are excluded from eligibility. The intent behind the initiative is to reduce the sustainable building processing time by up to 25%.

Under Decision 14-11-042, utilities to are permitted to continue using The Renewable Auction Mechanism (RAM) as a mechanism for meeting a portion of their RPS requirements. While some new parameters were established and the CPUC lifted, the essence of the RAM program will remain. The aim of this program is to streamline the procurement process for distributed generation projects between 3 MW and 20 MW while ensuring lower costs for utilities customers. The reverse auction is scheduled to occur twice annually for each of the three investor-owned utilities in the state. The last auction closed in 2015, and it was sixth in the series. Project size requirements are at the discretion of the utility and are based on their specific procurement needs at the time of the solicitation.

The CaliforniaFIRST Program operates in conjunction with the Property Assessed Clean Energy (PACE) financing program for non-residential properties. Under the program’s financing proposal, property owners may elect to finance green energy and water improvements on their buildings that can be paid back through their property taxes. Eligible California properties include commercial, industrial, agricultural, and multi-family (over 5 units) buildings in one of the 120 participating cities or the unincorporated parts of the 14 participating counties. Property records are used for establishing participation. All required property payments must be current, and a review of mortgage payment history along with other credit history criteria are required.

In September 2012 The California Public Utilities Commission (CPUC) enacted the first fundamental redesign of Rule 21 in over 11 years. The revised Rule 21 Tariff is described on page 136 of the CPUC Decision. Subsequent individual tariffs adopted by the utilities can be reviewed on the CPUC website. Rule 21 directs a specified screening process to allocate applicants into the path most suitable for their projects. The tariff also defines several fees and deposits required at various stages of the interconnection process. Once the utility performs and approves an initial review the system can interconnect without an additional supplemental review.

The County of San Diego’s Green Building Incentive Program is designed to encourage the adoption of efficient construction materials, water conservation, and energy efficiency in new and remodeled residential and commercial buildings. To incentivize these practices, San Diego County will reduce plan check and building permit fees by 7.5%. Expedited plan checks will be supplied to applicants who have qualified for the conservation incentive. Additional rebates and incentives may be available depending on the energy conservation technologies installed.

GreenFinaceSF is a Property Assessed Clean Energy financing program for commercial properties. It uses a PACE model in which individual property owners identify their project lenders and negotiate the financing terms with them. The city collects loan repayments from participants through a special property tax lien and disburses the money to the lender. This should provide greater security to the lender, who in turn should be able to provide more favorable terms to the property owner. The property must be located in San Francisco city and county, and be current with all financial obligations. The property must also have an energy and water audit. For more details see the program website for additional rules and restrictions.

Zoning laws in San Diego County contain special provisions for solar energy systems in unincorporated regions. Photovoltaic systems which a facility uses for self-consumption are classified as accessories allowable in all zone types. They must meet all requirements for accessories within the zone. Photovoltaic systems used for offsite power consumption are allowed in land of any zone type with a building permit from the county, provided the land is not more than 10 acres. Offsite solar systems on plots larger than 10 acres are considered utilities and require a Major Use Permit.

Marin Clean Energy is a community choice aggregator located in the northwest San Francisco Bay Area. CCAs purchase energy from specially selected sources their stakeholders choose, offering participating communities greater choice in green energy adoption. Currently, all Marin County residents are enrolled in MCE by default, though they may decline to participate. MCE funds new local renewable energy, including solar, wind, biomass, and fuel cell generation, through a "feed-in tariff." As enrollees install interconnected solar or wind energy systems on their own property, they will receive a fixed rate per kilowatt hour that returns to the network. Tariff amounts are based on energy capacity and characteristics of the systems MCE purchases. Incentives expire at the conclusion of a 20-year term.

SB 100 is a Special Bill that was signed into California state law in September 2018. The law altered some rules governing the use of hydro by public, municipally-owned facilities. The bill stipulates that 60% of all retail sales must come from renewable energy sources by 2030, and 100% of all retail sales shall originate from renewable energy and zero-carbon resources by 2045. The Energy Commission publishes two approved guidebooks that enumerate the various eligibility requirements under the Renewables Portfolio Standard program. Interested parties should reference these manuals to determine the specific standards and targets of the RPS program established in this bill.
