Mandolin Storage SLF (queue ID ERCOT-26INR0528) is a proposed battery energy storage development project in Starr County, Texas, within the Electric Reliability Council of Texas (ERCOT) region. The project is being developed by Mandolin Energy Center I, LLC. It is classified as a hybrid project, with technology components listed as battery energy storage and an additional component categorized as "Other." Total capacity and individual component capacities are not specified in the available queue data.
The project entered the ERCOT interconnection queue on July 22, 2024, and its queue status is active. Its proposed commercial operation date is June 15, 2029. The planned point of interconnection is a tap on the 345 kV transmission line between the Del Sol (bus 80355) and Rapido (bus 80227) substations. The status of an interconnection agreement for the project is not indicated in the available data.
