Wichita ? After a slow start to 2014, several wind energy projects in Kansas are under construction and more are planned once utilities have signed contracts to purchase the power they generate.

The Wichita Eagle reports the state has nearly 3,000 megawatts of wind energy capacity in 25 wind farms, and four wind farms under construction bring an additional 475 megawatts. Six other wind farms under development and approved for construction have a combined capacity for 1,800 more megawatts.

Federal wind energy tax credits expired at the end of last year, but by law developers can still qualify for the credits if their wind farms were started in 2013 and are finished by 2016.

Developers say some of the projects are on hold until utilities agreed to purchase power from them.
