(a)
(1)
Except as specified in paragraph (2), the commission shall require a green tariff shared renewables program to be administered by a participating utility in accordance with this section.
(2)
On and after April 1, 2023, the commission may authorize through an advice letter a participating utility to terminate its green tariff shared renewables program.
(b)
Generating facilities participating in a participating utility’s green tariff shared renewables program shall be eligible renewable energy resources with a nameplate rated generating capacity not exceeding 20 megawatts, except for those generating
facilities reserved for location in areas identified by the California Environmental Protection Agency as the most impacted and disadvantaged communities pursuant to paragraph (1) of subdivision (d), which shall not exceed one megawatt nameplate rated generating capacity.
(c)
A participating utility shall use commission-approved tools and mechanisms to procure additional eligible renewable energy resources for its green tariff shared renewables program from electrical generation facilities that are in addition to those required by the California Renewables Portfolio Standard Program (Article 16 (commencing with Section 399.11) of Chapter 2.3 of Part 1). For purposes of this subdivision, “commission-approved tools and mechanisms” means those procurement methods approved by the commission for an electrical corporation to procure
eligible renewable energy resources for purposes of meeting the procurement requirements of the California Renewables Portfolio Standard Program (Article 16 (commencing with Section 399.11) of Chapter 2.3 of Part 1).
(d)
A participating utility shall permit customers within the service territory of the utility to purchase electricity pursuant to the tariff approved by the commission to implement the utility’s green tariff shared renewables program, until the utility meets its proportionate share of a statewide limitation of 600 megawatts of customer participation, measured by nameplate rated generating
capacity, or the participating utility’s green tariff shared renewables program is terminated or suspended. The proportionate share shall be calculated based on the ratio of each participating utility’s retail sales to total retail sales of electricity by all participating utilities. The commission may place other restrictions on purchases under a green tariff shared renewables program, including restricting participation to a certain level of capacity each year. The following restrictions apply to the statewide 600 megawatt limitation:
(1)
(A)
One hundred megawatts shall be reserved for facilities that are no larger than one megawatt nameplate rated generating capacity and that are located in areas previously identified by the California Environmental Protection Agency as the most impacted and disadvantaged
communities. These communities shall be identified by census tract, and shall be determined to be the most impacted 20 percent based on results from the best available cumulative impact screening methodology designed to identify each of the following:
(i)
Areas disproportionately affected by environmental pollution and other hazards that can lead to negative public health effects, exposure, or environmental degradation.
(ii)
Areas with socioeconomic vulnerability.
(B)
For purposes of this paragraph, “previously identified” means identified before commencing construction of the facility.
(2)
Not less than 100 megawatts shall be reserved for
participation by residential class customers.
(3)
Twenty megawatts shall be reserved for the City of Davis.
(e)
To the extent possible, a participating utility shall seek to procure eligible renewable energy resources that are located in reasonable proximity to enrolled participants.
(f)
A participating utility’s green tariff shared renewables program shall support diverse procurement and the goals of commission General Order 156.
(g)
A participating utility’s green tariff shared renewables program shall not allow a customer to subscribe to more than 100 percent of the customer’s electricity demand.
(h)
Except
as authorized by this subdivision, a participating utility’s green tariff shared renewables program shall not allow a customer to subscribe to more than two megawatts of nameplate generating capacity. This limitation does not apply to a federal, state, or local government, school or school district, county office of education, the California Community Colleges, the California State University, or the University of California.
(i)
A participating utility’s green tariff shared renewables program shall not allow any single entity or its affiliates or subsidiaries to subscribe to more than 20 percent of any single calendar year’s total cumulative rated generating capacity.
(j)
To the extent possible, a participating utility shall actively market the utility’s green tariff shared renewables
program to low-income and minority communities and customers.
(k)
Participating customers shall receive bill credits for the generation of a participating eligible renewable energy resource using the class average retail generation cost as established in the participating utility’s approved tariff for the class to which the participating customer belongs, plus a renewables adjustment value representing the difference between the time-of-delivery profile of the eligible renewable energy resource used to serve the participating customer and the class average time-of-delivery profile and the resource adequacy value, if any, of the resource contained in the utility’s green tariff shared renewables program. The renewables adjustment value applicable to a time-of-delivery profile of an eligible renewable energy resource shall be determined according
to rules adopted by the commission. For these purposes, “time-of-delivery profile” refers to the daily generating pattern of a participating eligible renewable energy resource over time, the value of which is determined by comparing the generating pattern of that participating eligible renewable energy resource to the demand for electricity over time and other generating resources available to serve that demand.
(l)
Participating customers shall pay a renewable generation rate established by the commission, the administrative costs of the participating utility, and any other charges the commission determines are just and reasonable to fully cover the cost of procuring a green tariff shared renewables program’s resources to serve a participating customer’s needs.
(m)
A
participating customer’s rates shall be debited or credited with any other commission-approved costs or values applicable to the eligible renewable energy resources contained in a participating utility’s green tariff shared renewables program’s portfolio. These additional costs or values shall be applied to new customers when they initially subscribe after the cost or value has been approved by the commission.
(n)
Participating customers shall pay all otherwise applicable charges without modification.
(o)
A participating utility shall permit a participating customer to subscribe to the program and be provided with a nonbinding estimate of reasonably anticipated bill credits and bill charges, as determined by the commission, for a period of up to 20 years.
(p)
A participating utility shall provide support for enhanced community renewables programs to facilitate development of eligible renewable energy resource projects located close to the source of demand.
(q)
The commission shall ensure that charges and credits associated with a participating utility’s green tariff shared renewables program are set in a manner that ensures nonparticipant ratepayer indifference for the remaining bundled service, direct access, and community choice
aggregation customers and ensures that no costs are shifted from participating customers to nonparticipating ratepayers.
(r)
A participating utility shall track and account for all revenues and costs to ensure that the utility recovers the actual costs of the utility’s green tariff shared renewables program and that all costs and revenues are fully transparent and auditable.
(s)
Any renewable energy credits associated with electricity procured
by a participating utility for the utility’s green tariff shared renewables program and used by a participating customer shall be retired by the participating utility on behalf of the participating customer. Those renewable energy credits shall not be further sold, transferred, or otherwise monetized for any purpose. Any renewable energy credits associated with electricity procured by a participating utility for the green tariff shared renewables program, but not used by a participating customer, shall be counted toward meeting that participating utility’s renewables portfolio standard.
(t)
A participating utility shall, in the event of participant customer attrition or other causes that reduce customer participation or electrical demand below generation levels, apply the excess generation from the eligible renewable energy resources procured
through the utility’s green tariff shared renewables program to the utility’s renewable portfolio standard procurement obligations or bank the excess generation for future use to benefit all customers in accordance with the renewables portfolio standard banking and procurement rules approved by the commission.
(u)
In calculating its procurement requirements to meet the requirements of the California Renewables Portfolio Standard Program (Article 16 (commencing with Section 399.11) of Chapter 2.3 of Part 1), a participating utility may exclude from total retail sales the kilowatthours generated by an eligible renewable energy resource that is credited to a participating customer pursuant to the utility’s green tariff shared renewables program, commencing with the point in time at which the generating facility achieves commercial
operation.
(v)
All renewable energy resources procured on behalf of participating customers in the participating utility’s green tariff shared renewables program shall comply with the State Air Resources Board’s Voluntary Renewable Electricity Program. California-eligible greenhouse gas allowances associated with these purchases shall be retired on behalf of participating customers as part of the board’s Voluntary Renewable Electricity Program.
(w)
A participating utility shall provide a municipality with aggregated consumption data for participating customers within the municipality’s jurisdiction to allow for reporting on progress toward climate action goals by the municipality. A participating utility shall also publicly disclose, on a geographic basis, consumption data and
reductions in emissions of greenhouse gases achieved by participating customers in the utility’s green tariff shared renewables program, on an aggregated basis consistent with privacy protections as specified in Chapter 5 (commencing with Section 8380) of Division 4.1.
(x)
This section does not prohibit or restrict a community choice aggregator from offering its own voluntary renewable energy programs to participating customers of the community choice aggregation.
