Southwest Gas adjusts rates to reflect changes in the Gas Cost rate for Nevada customers on a quarterly basis. The rate is composed of the Base Tariff Energy Rate (BTER) and the Deferred Energy Account Adjustment (DEAA). This rate is updated to account for changes in the cost of natural gas the Company purchased on behalf of customers, with no profit to the Company, and uses a rolling 12-month average of natural gas costs.
The Company makes these quarterly advice letter filings in February, May, August, and November. Copies of Nevada Advice Letters can be found
