This fact sheet is intended to provide a general summary only. For specific legal authority concerning gas cost adjustment proceedings, please refer to the Indiana Code (IC 8-1-2-42(g)) and the Indiana Administrative Code (IAC 170). Both are available on the Internet at
www.IN.gov/legislative/ic_iac and at local libraries.
The Gas Cost Adjustment (GCA) is a periodic rate adjustment that allows natural gas utilities to account for changes in the price of natural gas they purchase on the competitive wholesale market. This process, which applies to all regulated * natural gas utilities in Indiana, was created by and is administered under state law.
Natural gas utilities have been using the GCA process for a number of years (in most cases, since the early 1980s). The GCA process came into existence after two major events: 1) The energy crisis of the 1970s and 2) The federal government’s approval of the Natural Gas Act of 1978, which removed federal price controls on wholesale natural gas markets.
The GCA process has traditionally been “invisible” on monthly consumer bills. Recently, however, some Indiana natural gas utilities have started to specifically identify the “Gas Cost Adjustment” in a line item on each bill.
The Indiana Office of Utility Consumer Counselor (OUCC) encourages consumers to be aware of several facts about GCAs and the GCA process:
1. Regulated natural gas utilities are allowed by law to make these adjustments to recover actual wholesale costs.
2. A GCA has two basic components.
3. Every GCA filing receives a thorough review by the Indiana Office of Utility Consumer Counselor (OUCC) and the Indiana Utility Regulatory Commission (IURC).
4. Natural gas utilities submit GCA filings to the Indiana Utility Regulatory Commission (IURC) on a regular basis, and must receive IURC approval before factoring the adjustments into consumer bills.
5. Once a GCA is approved, the utility adds it to, or subtracts it from, the base rates. In order to change base natural gas rates, a full rate proceeding before the IURC is required.

* Under Indiana law (IC 8-1.5-3), municipal natural gas utilities may withdraw from IURC jurisdiction of their rates, charges and finances. For more information, please see the OUCC Fact Sheet on Utility Withdrawal from IURC Jurisdiction.
** Northern Indiana Public Service Company (NIPSCO) uses a monthly GCA as a result of its natural gas Choice program. NIPSCO’s alternative regulatory plan also includes a Gas Cost Incentive Mechanism (GCIM) that allows consumers to share in the savings if the company’s purchase prices are lower than market indexes.
Citizens Gas & Coke Utility and Vectren Energy Delivery make limited monthly adjustments.
Valley Rural Utility Company (VRUC) operates under an alternative regulatory plan in providing natural gas service to customers in Dearborn County. VRUC is a very small, not-for-profit utility.
The Indiana Office of Utility Consumer Counselor (OUCC) is the state agency that represents the interests of all utility consumers and the general public in matters related to the provision of utility services. The agency is active in proceedings before regulatory and legal bodies, and committed to giving consumers a voice in the creation of utility service policy.
