Cogeneration plant to increase output by up to 22 megawatts
The California Energy Commission has approved modifications to the Procter and Gamble Cogeneration Project in south Sacramento that would increase the power plant's generation output by up to 22 megawatts.
By a vote of 4-0, the Commission allowed the 164-megawatt facility adjacent to the Procter and Gamble manufacturing plant on Fruitridge Road to upgrade three combustion turbines with new technology. The approval also would enable the plant to improve efficiency (heat rate), and reduce natural gas usage and greenhouse gas emissions on a per-megawatt-hour basis. The upgrades will also reduce the amount of smog-forming nitrogen oxides emissions.
The petition to modify, approved by the Commission today, was filed by the Sacramento Cogeneration Authority, a joint power authority affiliated with the Sacramento Municipal Utility District (SMUD).
The municipal utility will upgrade the turbines in three phases. The first installation, to be completed this summer will generate about eight additional MW. The second turbine will be installed in February 2009 and contribute the same output. The third turbine, expected to produce up to five additional megawatts will be installed by December 2009.
After the Commission's Compliance Monitoring Program received the petition in December of 2007, staff reviewed it for potential environmental effects in several technical areas. These included air quality, noise, water use, efficiency, and reliability.
Compliance and technical staff concluded that the modifications would have no significant impacts and the project would remain in conformity with all applicable laws, ordinances, regulations and standards.
The Sacramento Metropolitan Air Quality Management District evaluated the proposed changes in conformity with its rules and approved the installation of the plant's upgraded turbines on February 8, 2008. The modifications are part of a larger effort by SMUD to improve its carbon footprint.
The Energy Commission certified the Procter and Gamble Cogeneration Project in late 1994. The plant began commercial operation at the P&G site in 1996 to provide electricity to SMUD customers and steam created by the cogeneration process to the manufacturing facility.
The Commission's Compliance Monitoring Program monitors plants certified by the Commission during their construction, operation and up to their closure. The Program makes sure owners comply with all conditions of certification. The program's compliance activities also include analyzing amendments and changes to power plant facilities.
