Intermountain Gas seeks approval to sell surplus LNG

State regulators are taking public comment on an Intermountain Gas Company proposal to sell
its surplus liquefied natural gas to non-utility customers. The proposal would not increase
customer rates and could potentially decrease rates through the company’s annual Purchased
Gas Cost Adjustment (PGA) process.i

The natural gas distribution company expects to have excess capacity at its Nampa LNG facility
for the next few years. It proposes to sell that excess and share 50 percent of the sales revenue
with customers until system growth requires it to use all its LNG to meet peak-day needs for its
customers. The Idaho Public Utilities Commission is taking comments through March 18 on the
proposal.

The company says it will use all stored LNG to first satisfy utility customer demand, even if some
of the stored LNG was initially designated for non-utility sales. It will also provide a 2.5-cent
credit for each gallon sold to meet any operations and maintenance costs resulting from non-
utility sales and another 2.5 cents per gallon to meet any capital expenditures or increased
maintenance costs to the Nampa facility.

Under Intermountain’s proposal, all non-utility customers would be required to sign a contract
protecting its utility customers from financial risk as well as risks to the company after the LNG is
transferred to a non-utility customer. Intermountain Gas said it will accept all financial risk and
will insulate utility customers from any costs associated with non-utility sales by separately
accounting for and tracking all related costs independent of utility costs.

i The yearly Purchased Gas Cost Adjustment tracks gas supply and transportation costs that vary
from year to year. If those costs are higher than what is already included in rates, customers get
a one-year surcharge. If those costs are lower, customers get a credit. The PGA is usually
adjusted Oct. 1 of each year, but if gas prices materially change more than one adjustment can
be made during a year.
