THE EMPIRE DISTRICT ELECTRIC COMPANY

SIGNS WIND ENERGY CONTRACT

JOPLIN, MO – December 13, 2004 – The Empire District Electric Company (NYSE:EDE) announced today that it has signed a 20-year contract with PPM Energy, the U.S. competitive subsidiary of ScottishPower, to purchase the energy generated at the 150-megawatt Elk River Windfarm located in Butler County, Kansas, near Beaumont.  The Elk River project, developed by Greenlight Energy, of Charlottesville, Virginia, is in an area where the governor of Kansas has urged wind developers to move quickly to bring projects online.  Empire anticipates that it will purchase approximately 550,000 megawatt-hours of energy annually from the project, enough energy to meet the annual needs of about 42,000 homes.

In making the announcement, Brad Beecher, Vice President – Energy Supply, stated, “Today’s contract signing is a major step in ensuring that our customers benefit from a balanced mix of generation options.  With the improvements made in wind generation technology and the production tax credits that were recently enacted by Congress and signed into law by President Bush, wind energy provides price stability, is environmentally friendly, and is economical for our customers.”
