Renewable Portfolio Standard (RPS):
2015 Procurement Plans
Californian investor owned utilities are required to submit annual RPS Procurement Plans for CPUC approval (Public Utilities Code Section 399.13 (a) (1)). SB 350 increased the RPS target from 33% to 50% by 2030, with interim targets of 40% by the end of 2024, and 45% by the end of 2027.
The CPUC’s RPS Rulemaking provided direction to the utilities in formulating their Procurement Plans, including to provide:
- Assessment of annual and multi-year portfolio to determine the optimal mix of eligible renewable energy resources.
- An update on the development schedule of all eligible renewable resources currently under contract, but not yet delivering generation.
- Risks such as compliance delays.
- Quantitative data and calculations relied upon to assess need.
- A bid solicitation protocol, including Least Cost-Best Fit
- Cost quantification.
- Minimum margin of procurement
- Utilities analysis, initiatives, and strategies to forecast, avoid and/or manage curtailment and over-generation.
Utility RPS Procurement Plan Compliance Filing
In August 2015, the utilities filed their draft 2015 RPS Procurement Plans:
Interim CPUC Decision
On December 17, 2015, the CPUC issued an interim Decision
the utilities’ draft 2015 RPS Procurement Plans, and directing them to file
their final 2015 RPS Plans.
RPS Procurement Plans should provide a detailed description of the utility’s Least-Cost / Best-Fit methodology. The utilities should select renewable resources that are least cost, including the direct costs of renewable energy generation and any indirect costs due to integration of the resource and needed transmission interment. ORA supports approaches that will mitigate higher RPS costs such as establishing the Procurement Expenditure Limitation and limiting the voluntary margin of over-procurement.
