DOUGLAS, Wyo. (AP) — Duke Energy says it's Top of the World wind farm in Converse County doesn't produce as much energy as the company's other Wyoming wind farms and its tax valuation should be cut nearly in half.

The Associated Press reports  that the energy company disputes the Wyoming Department of Revenue's $414.7 million valuation. The company says an independent estimate places the wind farm's valuation at $225 million.

If Duke prevails, its tax liability would drop to $1.57 million from $2.89 million.

Duke spokeswoman Tammi McGee says the amount of energy produce is a factor in the lower valuation. Top of the World is one of four of Duke Energy Wyoming wind farms. Top of the World is the only valuation under dispute.
