Avista Receives Commission Decision in Oregon Natural Gas Rate Case

SPOKANE, Wash., Sept. 22, 2017 -- Avista’s (NYSE:AVA) natural gas rate case has concluded with an order from the Public Utility Commission of Oregon (PUC) that approves the all-party settlement filed in May 2017.

The Commission approved rates designed to increase annual billed revenues by 3.7 percent or $3.5 million. A rate adjustment of $2.6 million will be effective Oct. 1, 2017, and a second adjustment of $0.9 million will be effective Nov. 1, 2017 to cover specific capital projects identified in the settlement agreement, which are expected to be completed in October.

“The Commission’s decision represents positive outcomes for our customers, the company and our shareholders,” said Dennis Vermillion, Avista Corp. senior vice president and president of Avista Utilities. “It supports Avista’s efforts to continue to make key capital investments in our natural gas utility infrastructure as well as recover the operating costs of serving our customers.”

The Commission’s decision reflects a 9.4 percent return on equity (ROE), and a 50 percent equity layer. The rate of return is 7.35 percent.

Including both the Oct. 1 and Nov. 1 rate adjustments, a residential customer using an average of 47 therms per month would see a $1.57 per month increase, or 2.8 percent, for a revised monthly bill of $57.75, effective by Nov. 1, 2017. The bill change reflects an increase in the monthly basic charge from $9.00 to $10.00.

The actual percentage increase will vary by customer class and will depend on how much energy a customer uses.

Avista serves approximately 99,000 customers in Oregon.
