Chemical Water Treatment Services for Glenarm Power Plant

The City of Pasadena Water & Power Department is seeking proposals for chemical water treatment services at its Glenarm Power Plant, which operates five natural gas-fired combustion turbines. The plant includes two older Curtiss-Wright simple cycle turbines from 1974 and three modern GE LM6000 units, with GT5 being a combined cycle unit outfitted with a steam turbine and once-through steam generator. Together, these units have a generating capacity of approximately 197 megawatts. The plant utilizes several cooling towers associated with different units and relies on city water as make-up water for cooling, as well as a reverse osmosis water conditioning system that supplies treated water for critical functions including steam cycle make-up, evaporator cooling, and NOx reduction. This solicitation, identified as 2025-RFP-0311, was posted on December 19, 2025, with a response deadline of January 15, 2026. The contract is managed by the Pasadena Water & Power Department’s Power Supply office and aims to secure a contractor for ongoing chemical treatment to ensure efficient and reliable plant operation. Key contacts include the Power Plant Manager and Project Manager, with services to be performed within California. The comprehensive treatment services are essential for maintaining the operational integrity of the plant’s water systems, supporting both environmental compliance and equipment longevity.
