PUC Gives Idaho Power, Solar Developer a Week to Fix Math

by

The Idaho Public Utilities Commission has ordered Idaho Power and a solar power developer to re-check their math, fast.

Idaho Power had struck a deal with Interconnect Solar Development in which the utility would pay $105.25 per megawatt-hour for power generated from a photovoltaic project near Murphy in Owyhee County. The cost of the power would be passed on to consumers. But following production requests from the PUC, Idaho Power identified errors that, if corrected, would result in a price of $94.59 per MWh.

Interconnect Solar is fighting the new findings, stating that the lower price would render the project no longer viable.

The PUC is giving the parties until Sept. 27 to propose a corrected price before making a final determination on the entire agreement.
