Green Mountain Power Receives Environmental Recognition.

WATERBURY, Vt. -- Green Mountain Power Corporation (NYSE: GMP) has been recognized by the Vermont Department of Environmental Conservation and the Vermont Small Business Development Center as an Environmental Partner in the Vermont Business Environmental Partnership for its excellent environmental management practices, "green" purchasing, and forward thinking environmental policies.

"Green Mountain Power is taking steps to address its environmental impacts. In doing this, the Company has implemented numerous practices that go beyond compliance," said Department of Environmental Conservation Commissioner Jeff Wennberg.

Green Mountain Power serves 90,000 customers within the State of Vermont and sells electricity and energy services to approximately 25% of Vermont's retail electricity customers, serving half of the state's 14 counties. While most of the power-producing facilities in the United States rely on burning coal to generate electricity, Green Mountain Power has among the "greenest" energy portfolios of all power companies in the nation. At present, Green Mountain Power generates electricity without any coal, and only four percent of its generation comes from fossil fuels. (Purchases on the New England wholesale market account for 19 percent of the power mix, but cannot be broken down into fuel source.) More than forty percent of Green Mountain Power's energy comes from renewable sources: hydro, wood and wind.

Examples of Green Mountain Power's "green" practices include eliminating two hazardous waste streams. To accomplish this Green Mountain Power replaced chlorinated solvent-based parts cleaning with non-hazardous citrus-based solvents and aqueous based cleaners. Additionally, Green Mountain Power substituted ethylene glycol antifreeze for less toxic propylene glycol in its vehicles when possible, and recycles the antifreeze on-site for reuse in its vehicles. Green Mountain Power's workspace is very efficient, as the smaller, open-office design uses fewer resources. In addition, the company has invested in energy efficient lighting and "green" building practices in its facilities (i.e. installing recycled tire flooring and carpeting), and diverts hundreds of pounds of solid waste from landfill disposal through its recycling programs.

Other noteworthy practices include not using herbicides on power line rights-of-way, the purchase and use of hybrid and low emission vehicles in its fleet, and subscribing to vehicle idling guidelines to minimize emissions. Green Mountain Power has also started to utilize a 20% biodiesel mixture in its larger vehicles.

According to Chris Dutton, Green Mountain Power's President and Chief Executive Officer, "Energy efficiency and other environmentally friendly practices make as much sense economically as they do for the health of the environment. We're honored to receive this recognition for the work that we do and for making our own office a healthy, positive place to work."
