Modesto Irrigation District Electrical System Improvement (ESI) Program 2026-2033

The Modesto Irrigation District Electrical System Improvement (ESI) Program 2026-2033 is a multi-county electrical expansion project designed to meet existing and anticipated electrical demands within the district's service area. The program covers approximately 568 square miles across Stanislaus, San Joaquin, and Tuolumne counties, including a traditional service area of 160 square miles in Stanislaus County and an eight-square-mile area in the City of Mountain House. The project is currently focused on CEQA environmental review for activities planned between 2025 and 2032, utilizing a Program Environmental Impact Report to analyze potential effects on biological resources, greenhouse gases, wildfire risks, and cultural resources. The program is managed by the Modesto Irrigation District, with administrative oversight provided by Esteban Martinez and Subbaiah Pasupulati. Key regulatory requirements include conducting biological surveys by qualified professionals to identify special-status species and reporting findings to the CNDDB. The project has undergone a public review process from November to December 2025, with a Notice of Determination filed in January 2026 to certify compliance with the Public Resources Code. Performance for the ESI Program is scheduled for the 2026 through 2033 period, focusing on improving system reliability and expanding infrastructure in Modesto and surrounding regions.
