Jack Fusco, President and Chief Executive Officer of Calpine Corporation (NYSE:CPN), is scheduled to attend the National Association of Regulatory Utility Commissioners (NARUC) Annual Meeting in Atlanta, Georgia, today, where he will deliver a brief company presentation as part of a panel discussion titled ?Say Hello to an Old Friend: The Future Role of Natural Gas in the Electrical Sector.?

Mr. Fusco will address the vital role natural gas-fired power plants could play in immediately reducing our nation's greenhouse gas (GHG) and other air emissions like mercury and acid gases compared to older coal plants. For example, simply substituting unutilized existing gas-fired capacity for dirtier generation sources could immediately reduce power sector CO2 GHG emissions by up to 20%. He will also discuss how abundant shale gas supplies in the United States will make it a cost-effective fuel source for electric generation.

The panel discussion will take place at 10:30 a.m. EST/9:30 a.m. CST, during a joint session of NARUC's Committee on Electricity and Committee on Gas.
