Quick Facts:
- Gas Cost Adjustments (GCAs) are used to recover actual wholesale gas costs.
- Utilities may not profit from GCAs.
- GCAs are thoroughly reviewed by the State before being implemented in bills.
- Regulated natural gas utilities have used the GCA process since the 1980s.
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).
Background
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. However, some Indiana natural gas utilities specifically identify the “Gas Cost Adjustment” in a line item on each bill.
The GCA Process
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.
- Utilities may not profit from these adjustments, but merely recover the price they have paid for gas.
- Prices on the competitive wholesale market for natural gas are volatile. They can sharply increase or decrease in a short period of time.
- Before natural gas utilities can pass wholesale costs to consumers through GCAs, they must prove that they have made every effort to procure gas at the lowest cost reasonably possible.
2. A GCA has two basic components.
- An estimate of the market price of the natural gas itself, along with transportation charges to deliver it to the utility over the upcoming GCA period; and
- A “true-up” to correct overestimates and/or underestimates from previous GCA periods. The “true-up” amount is usually recovered or reimbursed over a 12-month period.
3. Every GCA filing receives a thorough review by the Indiana Office of Utility Consumer Counselor (OUCC) and the Indiana Utility Regulatory Commission (IURC).
- The OUCC reviews GCA filings on behalf of consumers.
- By law, the IURC’s review and decision must balance utility and consumer interests.
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.
- Natural gas utilities currently submit GCA filings every three months. However, smaller utilities (with fewer than 35,000 customers) may receive approval to file every six months.
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.
