The new law will permit the state to issue up to $5 million in bonds to help such firms.
Gov. Kathleen Sebelius pushed the measure as a way to make Kansas a center of research and development for renewable energy technology.
Legislators passed a bill unanimously, and she signed it Monday. It takes effect April 16.
Companies will be eligible for the state's help if they expect to invest at least $30 million in Kansas and have at least 200 full-time workers within five years. Also, a company will have to pay an average salary of $32,500 to its Kansas employees.
