resource adequacy vs capacity

Planned Financed Generation Capacity Resource means a Planned Generation Capacity Resource that, prior to August 7, 2015, has an effective Interconnection Service Agreement and has submitted to the Office of the Interconnection the appropriate certification attesting achievement of Financial Close. This voluntary annual capacity auction provides a way for Market Participants to meetresource adequacy requirements. The electric utility industry employs a fairly simple concept for maintaining reliability: utilities must ensure they have enough electric supply available to serve their total electric load and then have a required cushion of electric supply beyond their peak load. More. In addition, the CAISO will determine if all dispatchable Resource Adequacy Capacity from Short Start Units, not otherwise selected in the IFM or RUC, is reflected in a Bid into the Real-Time Market and will insert a Generated Bid for any remaining dispatchable Resource Adequacy Capacity for which the CAISO has not received notification of an Outage. Training opportunities and knowledge resources will also be communicated through this site. In so doing, the IFM will honor submitted Energy Self-Schedules of Resource Adequacy Capacity unless the CAISO is unable to satisfy one hundred percent (100%) of the Ancillary Services requirements. This extra capacity is known as reserve capacity. Resource Adequacy Capacity participating in RUC will be optimized using a zero dollar ($0/MW-hour) RUC Availability Bid. The Resource Adequacy program has two goals: To ensure the safe and reliable operation of the grid in real-time providing sufficient resources to the California Independent System Operator (CAISO) when and where needed. It is the difference between: (a) that which a facility could achieve under 100 percent operating time on a one-shift basis less operating interruptions resulting from time lost for repairs, setups, unsatisfactory materials, and other normal delays; and (b) the extent to which the facility was actually used to meet demands during the accounting period. MEANs projected 2022 summer peak load in SPP is 156 megawatts. 6 Capital Is Invested in Generation Capacity for Three Reasons, and Two of them Are Subject to Free-Riding 1) To produce an instantaneous flow of power to assure system reliability So-called "pure capacity" (i.e., ability to meet load) 2) To gain access to lower operating costs e.g., cheaper fuels (coal), lower heat rates (CCGTs vs. CTs) 3) To pursue public policy goals California Independent System Operator | P.O. 0 California's resource adequacy (RA) program is a critical tool to ensure load-serving entities (LSEs) procure the resources that are needed to keep the lights on. 0000001289 00000 n Prior to running the Real-Time Market, the CAISO will determine if Resource Adequacy Capacity subject to the requirements of Section 40.6.2 and for which the CAISO has not received notification of an Outage has not been reflected in a Bid and will insert a Generated Bid for such capacity into the Real-Time Market. . 137 0 obj<>stream Planning Resource Auction (PRA) This voluntary annual capacity auction provides a way for Market Participants to meet resource adequacy requirements. 0000016985 00000 n California's program has three different types of resource adequacy requirements, each designed to keep the grid operating under different types of conditions: System Capacity: These requirements help keep the lights on during the annual "peak load," when California uses the most electricity. MISOs Resource Adequacy constructcomplements the jurisdiction that regulatory authorities have in determining the necessarylevel of adequacy and works in concert with Load Serving Entities (LSEs) that providedemand forecasts that help drive the development of local and regional requirements. Having a built-in reserve capacity of electric supply provides for a "cushion" for situations that might require more electricity such as during power plant outages (planned or unplanned), unavailability of intermittent power resources (wind and solar electric generation) and transmission . The assessments highlight potential issues in the upcoming seasons to helpsystem operators and stakeholders prepare for potential strained system conditions anddevelop preventative actions. In recent years, this framework has been recommended by an IEEE task force [1], the North American Electric Reliability 0000009649 00000 n Sample 1 Based on 4 documents 0000002691 00000 n Base Capacity Resource means a Capacity Resource as described in Tariff, Attachment DD, section 5.5A(b).

For end users, "reliability" is a combination of three distinct components: Distribution system reliability Transmission system reliability Resource adequacy(bulk power supply vs. load) Auction cycle will move from annual to seasonal auction (clearing all four seasons still once yearly). 0000003108 00000 n THE CURRENT RA PARADIGM IS AT BEST "BARELY WORKING" - AND AT WORST "ISN'T DOING ITS PRIMARY JOB." WHY? IMM 2018-5 This issue was identified in 2018 as a Phase 2 issue of Resource Availability and Need (IR025) and was redefined ahead of the 2021 Integrated Roadmap Work Plan prioritization in an effort to further break out RAN projects. 0000003427 00000 n The report will not include commitments of RMR Generation capacity, Resource Adequacy Capacity or designated CPM Capacity. Electricity is generated and consumed simultaneously in real time, so electric utilities and organizations responsible for coordinating the dispatching and transmission of electricity on the electric grid must ensure there is always an adequate supply of electricity to meet periods of peak electric demand. (1) show the resource to reduce the central procurement entity's (CPE) overall local procurement obligation and retain the resource to meet its own system and flexible RA needs, (2) bid the resource into the CPE's solicitation, or (3) elect not to show or bid the resource to the CPE and only use the resource these resources can make toward planning reserve. The location-specific approach of the PRA encourages resources to be available when needed in the right locations in an economic and efficient manner. Qualifying Capacity (QC) values for any part proven to be undeliverable to the aggregate of load. Sierra and North Coast/North Bay areas."The market for capacity needed to meet local resource-adequacy requirements continues to be structurally uncompetitive in almost all . In addition to utilities having to meet their respective resource adequacy requirement, they also are required to have a percentage of extra electric capacity beyond what is needed to meet peak demand. These third-party DR resources have taken on resource adequacy commitments at capacity prices far below the cost of new generation and the "capacity value" assumed in California's DR cost-effectiveness tests. To incentivize the siting and construction of new resources needed for future grid reliability. The California ISO has posted the updated preliminary 2023 Resource Adequacy Net Qualifying Capacity (NQC) data on its website on the Reliability Requirements webpage, under the Net qualifying capacity (NQC) heading. Tacoma Power can access pooled capacity Energy efficiency means measures that reduce the amount. Monitoring Services shall have the meaning set forth in Section 2(b) of this Agreement. Resource Capacity Contributions to Resource Adequacy. The SPPs reserve capacity requirement is currently 12 percent for electric load-serving members, including the Municipal Energy Agency of Nebraska (MEAN). Resource Adequacy vs. In the simplest terms, RA is just a regulatory construct developed to ensure that there will be sufficient resources available to serve electric demand under all but the most extreme conditions. Resource Adequacy Capacity is that capacity in MW that has been approved by each Participant, acting as a local regulatory authority, as capacity available to ensure that adequate resources are available to meet peak demand and planning reserves for the purposes of local area and system reliability. The 2014 DGD study found far more deliverability available than in 2013. The growth of customer-owned resources is forcing system operators and aggregators to see their value as reliability tools and rethink the concept of resource adequacy. Resource Adequacy Benefits means the rights and privileges attached to the Facility that satisfy any entitys resource adequacy obligations, as those obligations are set forth in any Resource Adequacy Rulings and shall include any local, zonal or otherwise locational attributes associated with the Facility.
