About this file
The document is a comprehensive Technical Data spreadsheet for a Battery Energy Storage System (BESS) prepared for Pasadena Water and Power (PWP), a department of the City of Pasadena, California. The solicitation seeks a private entity to design, engineer, permit, finance, procure, operate, and maintain a 25 MW lithium-ion battery storage system with a minimum 4-hour storage capability at PWP's Glenarm Power Plant. The proposed project involves a minimum 15-year Energy Storage Agreement (ESA) with options for the City to purchase the BESS at the Commercial Operation Date, Year Two, and Year Five after COD. The technical specification covers extensive requirements across eleven sections including mandatory minimum requirements, performance standards, safety protocols, communications and controls, balance of system, installation details, mechanical and environmental specifications, operations and maintenance, and interconnection requirements.
The contract opportunity includes multiple technical and compliance specifications, with key requirements such as UL 9540 and UL 9540A safety certifications, compliance with California Rule 21 and IEEE 1547-2018 standards, and detailed operational parameters including a 100 MWh storage capacity, 60 Hz frequency, and 34.5 kV connection point. The proposal must demonstrate the BESS's ability to meet specific performance metrics like roundtrip efficiency, cycle life, calendar life degradation, and thermal management. Financial considerations include a 15-year warranty period, expected system availability metrics, and provisions for maintenance and potential system upgrades. The technical data spreadsheet serves as a comprehensive evaluation tool for potential bidders to demonstrate their system's capabilities and alignment with PWP's detailed technical and operational requirements.
