Results from the Water Research Center at Georgia Power’s 3,160 MW Bowen coal-fired power plant shows higher water efficiency with help from General Electric’s (NYSE:GE) water conservation pilot at the plant.
In May 2010, Georgia Power picked GE for its water conservation pilot at the plant. With the chemical treatment program, Plant Bowen was able to withdraw less water per day from the Etowah River during the six-month pilot study. The company’s main objective was to reduce water requirements for cooling tower operations an maintain the current level of operational efficiency.
In addition, corrosion control of the treated systems improved, extending the life expectancy of the piping, heat exchangers and other cooling system components in the plant. There was no adverse impact on the condenser performance and there were no operational interruptions or issues. The overall water savings for all seasons and modes of operation must still be evaluated.
GenGard, the chemical technology used in the pilot, is designed to reuse water multiple times in the cooling system while avoiding corrosion and fouling problems.
Georgia Power is collaborating with the Electric Power Research Institute to add broader industry perspective and guidance to the project. Expected to be fully operational by August 2012, the research center will include seven separate research focus areas in water treatment, usage and monitoring.
