Summary: Annual filing by Avista Corporation to review and confirm power cost deferrals in the 2014 Energy Recovery Mechanism. In sum, power costs were lower than the 2014 baseline by approximately $9.5 million. This was primarily due to increased hydro generation and reduced thermal generation. This increased the deferral account in the rebate direction by $4.1 million, including $80,000 in interest, to a total of $14.1 million.
