phase of the energy storage and distributed energy resources (ESDER) initiative, which was recently implemented, included development of market power mitigation for storage
This initiative will enhance the optimization, dispatch, and settlement of energy storage and other similarly-situated resources, through developing bid enhancements to help
The California ISO manages the flow of electricity across high-voltage, long-distance power lines, operates a competitive wholesale energy market, and oversees transmission
1 Introduction. Storage developers are rapidly deploying new utility-scale resources onto the California grid to provide replacement capacity for retiring resources and to meet
This report provides a description of the state of battery storage resources in the California ISO and Western Energy Imbalance M arket. We evaluate the performance of batteries using several k ey metrics, and assess the recent market enhancements for battery resources. 1 California ISO, 20 -Year Transmission Outlook,
updates the default energy bid for storage resources in the day-ahead market. This policy aligns the day-ahead and real-time default energy bids by including opportunity costs in
Storage initiative will improve reliability. By Gabe Murtaugh, Storage Sector Manager | 12/21/2022. After nearly two years of work by many people at the California ISO and constructive input from stakeholders, the energy storage enhancements final proposal was approved by our Board of Governors and the Western Energy Imbalance Market
Energy Storage Enhancements State of Charge Implementation Update. Oct 9, 2023. Housekeeping Reminders: • This call is engages stakeholders in review of market performance issues and in high level dialogue on release planning, implementation and new market enhancements. This is intended to foster open dialogue and sharing of
Scenario 2 (Unstructured): Verify hourly do not charge from the grid bidding functionality for standalone or sub-ACC constraints. Title. Action. Market participants should: Submit hourly bid attribute type in SIBR to not charge from the grid in the real-time market. Submit economic bids for all resources behind the ACC; for storage resources
The California ISO will offer a refresher training for the Energy Storage Enhancements - Track 1 initiative in a training webinar on June 22, 2023. The target audience for this session are entities with portfolios that currently include or plan to include storage resources. This webinar will cover changes to affected business processes and
CAISO Positions Against Explicit Grid-Charging Controls HRI Revised Straw Proposal (p.11): The CAISO notes the ITC as a business driver for hybrid and colocated resources - because it reduces the costs associated with developing new resources that contain solar and storage combinations. The CAISO believes that this
The Department of Market Monitoring (DMM) appreciates the opportunity to comment on the Energy Storage Enhancements – Final Proposal.1. DMM supports the proposed enhancements aimed at improving the availability of ancillary services awarded to energy storage resources, and the proposal to allow the CAISO to issue exceptional dispatches
CAISO energy storage enhancements. • CAISO''s revised straw proposal improves some areas, such as on compensation for exceptional dispatch. • CAISO
of the energy storage resource model. The ISO may consider not pursuing proposed changes related to a new storage model As proposed, scheduling coordinators, can model storage resources either with the energy storage resource model or the non-generator resource model. Scheduling coordinators may freely revert to one model or the other.
Scenario 2 (Unstructured): Verify hourly do not charge from the grid bidding functionality for standalone or sub-ACC constraints. Title. Action. Market participants should: Submit hourly bid attribute type in SIBR to not charge from the grid in the real-time market. Submit economic bids for all resources behind the ACC; for storage resources
These enhancements further improve the ability of energy storage and distributed energy resources to participate in the ISO market. Outcome (3A): Effective Nov. 13, 2019, the first phase of this initiative''s Phase 3 provided new dispatchable bidding options for DR resources and removed the single Load Serving Entity requirement for DR

• Compensating storage only if there are net revenue losses over narrower (e.g., 8 hour) windows rather than a full day will work only for resources following the simplest day-ahead energy-only schedules, for the same reason that looking at net revenue losses over an entire 24-hour period fails to make storage whole now.
FERC Requested Adjustments. In November 2019, FERC responded to CAISO''s compliance filing for FERC Order 841. FERC generally accepted the filing but took exception to certain proposed provisions. In response to FERC''s directives, the CAISO replied with a further compliance filing to address three (3) issues as noted below.
The Committee has held public meetings addressing this initiative on May 21, Aug. 27, and Oct. 1, 2021; and Feb. 11, Sept. 19, and Sept. 26, 2022. We also previously addressed the market power mitigation issues that are addressed in this initiative in our Opinion on the Energy Storage and Distributed Energy Resources Initiative Phase 4 (ESDER 4
The energy storage enhancements policy on state of charge was developed to address two concerns Page 4 1. Better alignment between day-ahead state of charge and actual state of charge in real-time –When storage resources provide regulating service it does impact state of charge –Regulation down increases state of charge
Measures targeting storage in the resource adequacy enhancements (RAE) initiative include counting rules and bidding obligations for storage resources and
CAISO - PUBLIC Energy storage enhancements includes changes to ensure reliable storage operation and modeling Page 2 Enhancements for reliability: 1. Improved accounting for state of charge while providing regulation 2. Enhanced bidding requirements for resources providing ancillary services 3. Exceptional dispatch tools for storage
– If a storage resource elects this operating mode, solar is not curtailed, and solar is less than forecast, then a storage resource may deviate down from dispatch instructions equal to the difference between the solar forecast and actual output – Storage resources that deviate will not receive unique settlement
energy storage enhancements stakeholder process. The purpose of the straw proposal is to include detailed solutions for resolving issues related to the integration, modeling, and participation of energy storage in the ISO market. The ISO will publish a number of straw proposals, and solicit stakeholder feedback after each iteration.
The Energy Storage Enhancements proposal was adopted by CAISO''s governing entities last week (16 December) and will be implemented by summer 2023, when extreme heat threatens the stability
