The Senate expects to debate a bill Thursday to clear the way for the plants and restrict the power of the secretary of health and environment to set emissions standards.
The House passed its own version of the measure last week. Sebelius is expected to veto it.
Sunflower Electric Power Corp., based in Hays, wants to build the two plants outside Holcomb, in Finney County. But Sebelius' secretary of health and environment denied Sunflower an air-quality permit in October 2007.
As with the House version, the Senate version ties those provisions to other, ``green'' measures designed to encourage the development of renewable energy sources.
