CHEYENNE, Wyo. (AP) — Several proposals that would raise taxes on wind energy in Wyoming have died in the state Legislature.

The bills included one to raise the $1 per megawatt hour tax to $4 per megawatt hour and another to add $4 to the existing tax for a total of $5 per megawatt hour.

A third proposal that would have imposed a five-year escalating tax also died.

The wind tax may still come up again in a different forum. Republican Sen. Cale Case, of Lander, has been a proponent of raising the tax for years and has encouraged an initiative attempt to put the wind tax on the ballot in 2020.
