Panno Substation Bank 1 Transformer Replacement

The Imperial Irrigation District is undertaking the Panno Substation Bank 1 Transformer Replacement project located at 1039 Panno Street in Brawley, California. The primary objective is to replace the aging Bank 1 power transformer and associated equipment, which has been in operation for approximately 61 years and has exceeded its useful service life. This project is designed to enhance system safety and reliability, reduce the risk of equipment failure, and ensure the maintenance of reliable electrical service. All activities, including engineering, procurement, and installation, will be conducted strictly within the existing IID-owned substation footprint. The scope of work encompasses comprehensive engineering and design services, the procurement of the replacement transformer, and detailed evaluations of the existing transformer foundation and associated substation equipment to determine if further in-footprint replacements are necessary. This project is classified under NAICS code 238210 and is determined to be categorically exempt under the California Environmental Quality Act (CEQA) Class 2, Section 15302 for Replacement or Reconstruction. The project was forecasted for September 2026, with environmental compliance managed by the Imperial Irrigation District.
