Partnering on a utility boiler retrofit: Approach and results

In 1993, Pacific Gas and Electric (PG&E) began the process of evaluating contracting options and selecting a contracting approach for use on its NO, retrofit program, which had the goal of achieving significant reductions in emissions from its gas and oil fired units. PG&E determined that partnering was the preferred method, based on its greater potential for both improved quality, risk identification and management, and cost control. Ultimately, Babcock & Wilcox (B&W) was selected as one of two partners and was assigned the retrofit of PG&E's 750 MW Moss Landing Unit 7, a supercritical, opposed wall-fired boiler that is configured with burners in ''three per'' cells and with modest flue gas recirculation (FGR) capability.
