G-PST/ESIG Webinar Series: Operational Experience with Battery Energy Storage in ERCOT

Описание: Featured Speaker: Nitika Mago, Manager, Balancing Operations Planning, ERCOT

About the Webinar: As of February 28, 2023, ERCOT has integrated about 3,014 MW of battery energy storage resource (includes standalone and co-located, transmission connected, and distribution connected) capacity on its grid. ERCOT is projecting to add an additional 4,028 MW by end of 2023. These battery energy storage resources are actively participating both in ERCOT’s Ancillary Service and energy markets. Since late 2019, ERCOT has developed several Market rules and implemented system changes to support integration of duration limited battery energy storage resources within its footprint and continue reliable grid operations. During the same time ERCOT has also brought about changes to the design of its Ancillary Services (aka “operational reserves”) program including creating a new Fast Frequency Response (FFR) product that can help improve frequency response and widen ERCOT’s operating range for inertia. This webinar will provide an overview of ERCOT’s experience (including challenges) with battery energy storage operations, share strategies including tools, procedures, and approaches that have been incorporated or are in the process of being implemented to improve ERCOT’s monitoring and modeling of battery energy storage capability (“state of charge”).
