Boise, Idaho (KMVT-TV) – Intermountain Gas Company said that they would like to decrease the price they charge customers by 2.4%. The company filed its annual Purchased Gas Cost Adjustment with the IPUC . The request is for a decrease of approximately $6-million Dollars and if approved would be effective October 1, 2012. Residential customers using gas for space and water heating will save an average 3.1% or $1.51 per month, while customers using natural gas only for space heating will see an average decrease of $0.17 per month or 0.4%, based on average weather and usage. Commercial customers, on average, would see a savings of $6.46 per month or 3.1%. In addition to the price reduction, the company is also proposing to pass back to its sales customers credits that have accrued as a result of falling gas prices subsequent to the February 2012 price decrease. If approved as filed, those credits will be directly refunded to Intermountain’s residential, commercial and LV-1 customers through a one-time bill credit in December 2012. Each sales customer’s refund will equal $.03877 per therm times the customer’s billed usage from July 1, 2011 through June 30, 2012. The one-time credit combined with the proposed PGA price change described above equals an overall price decrease of 7.1%.
