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. Which means you pay what we pay for the cost of natural gas. No more, no less.
The Company makes these quarterly advice letter filings in February, May, August, and November. Copies of Nevada Advice Letters can be found

Southwest Gas’ most recent Nevada Quarterly Gas Cost Rate Adjustment filing was made on May 24, 2023 to account for the natural gas costs purchased by the Company between April 2022 and March 2023. The updated Gas Cost rate will be effective July 1, 2023.
Recent Nevada gas costs have been higher as a result of several factors – supply/demand imbalance, the residual effects of winter storm Uri, and colder than normal western US weather during November 2022 through March 2023.
Due to the higher cost of natural gas, the average natural gas bill for Nevada customers is expected to increase. The estimated bill for an average southern or northern Nevada residential customer is shown in the table below.
| Annual Average1 | Summer Average2 | Winter Average3 | |
| Southern Nevada | $103.52 | $49.10 | $157.94 |
| Northern Nevada | $150.22 | $59.38 | $238.93 |
The estimated bills shown in the table above are based on the following average residential customer monthly usage. Your actual bill may be higher or lower depending on your specific usage.
1 Southern Nevada: 46 therms and Northern Nevada: 66 therms (April 2022 through March 2023)
