NS Power to invest $45M to reduce Trenton generating station emissions

TRENTON, NS-Nova Scotia Power plans to invest $45 million to improve the operational and environmental performance of its coal-fired Trenton generating station. In a submission to the provincial Utility and Review Board (UARB), NS Power outlined two projects focusing on Unit 5 of the facility. The utility is allocating $15 million to replace the unit's electricity generator and $30 million to install a new baghouse to reduce flyash emissions. "Adding a baghouse will result in greater fuel flexibility that will keep costs down for our customers, while at the same time reduce flyash and other emissions into the local environment," said Rick Janega, general manager of power production. The details of both proposals will be provided to local residents and other customers when a formal application is filed with the UARB between now and the end of 2006. If approved by the UARB, engineering design work would take place in mid- to late 2007, construction would begin in 2008 with project completion expected by mid-2009. The 150-megawatt Trenton power plant was built in 1969. NS Power works closely with the Department of Environment and Labour on its air quality program, which tackles broader goals such as reductions in sulfur dioxide (SO2), nitrogen oxides (NOX), and mercury. The utility has committed to reducing SO2 emissions to 50% of pre-2005 levels by 2010 and has set a 20% reduction target for NOX from 2000 levels by 2009.
