EIM Governing Body adopts initiatives for summer reliability

WesternEIM

To help maintain grid reliability this summer, the Western Energy Imbalance Market (EIM) Governing Body unanimously approved market and operational enhancements for Western EIM entities participating in the California Independent System Operator’s (ISO) real-time energy market.

The Governing Body’s decision on March 10 is under its primary approval authority and will:

  • Improve the resource sufficiency evaluation to ensure each balancing authority area participates in the Western EIM with the necessary resources; and
  • Enhance real-time energy market models to provide better operational coordination among balancing authority areas in the Western EIM.

Additionally, the Western EIM Governing Body provided, in its advisory capacity, support for a market-pricing enhancement for contingency reserves that will strengthen incentives during tight supply conditions. This item requires the approval of the ISO Board of Governors, and is included on the March 24 agenda, along with other Market Enhancements for Summer 2021 Readiness initiatives.

The ISO continues to set renewable energy records

RenewableRecords

The electric grid managed by the ISO continued to top renewable energy records in 2020, and set several new records this year, according to the company’s February Key Statistics. This fact sheet provides easy access to key data and raises awareness about the electric grid during its transition to clean energy.

Some highlights of the fact sheet include:

  • A historical peak of 89% of renewables serving load on February 27, 2021.
  • A historical solar generation peak of 12,335 megawatts (MW) on March 1, 2021.
  • Historic wind generation peak of 5,318 MW on April 30, 2020.

To view the ISO’s energy peaks and historical data by month, view Key Statistics on the News webpage. Follow the ISO’s real-time supply and demand, along with other valuable energy data points, at the ISO’s Today’s Outlook.

First Native American Tribe to become a transmission owner

MorongoTO

The Morongo Band of the Mission Indians is on track to become the first Native American tribe to be a participating transmission owner in the ISO footprint, creating a critical connection to help meet the state’s green energy goals.

The ISO Board of Governors recently approved the Morongo Transmission, LLC application, which is majority-owned by the Morongo Band of the Mission Indians. It marks the first time a federally recognized tribe has received the designation within the ISO’s balancing authority.

The Board’s action supports the completion of the West Devers project, which connects solar, wind, and battery resources located in eastern Riverside County and Imperial Valley to the grid.

Conservation during a Flex Alert alleviates energy shortages

FlexAlert

Californians who sign up to receive Flex Alert notifications will be among the first to know of tight electric grid conditions this summer, which can help them prepare before the conservation period starts.

A Flex Alert is a call for consumers to voluntarily conserve electricity to maintain grid stability due to a shortage in power supply, and help avoid the need for rotating power outages.

When a Flex Alert is issued by the ISO, consumers are encouraged to pre-cool their homes in preparation for energy reduction actions needed later in the day. Between 3 p.m. and 9 p.m., consumers are asked to conserve electricity by setting the thermostat to 78 degrees; turning off unnecessary lights; and avoiding the use of washers, dryers, dishwashers, and ovens.

To sign up for Flex Alert notifications and learn how to help the grid during times of stress, visit www.FlexAlert.org. Consumers can also follow @FlexAlert on Twitter for real-time updates.
