Here is an explanation of the terms used on your monthly Minnesota Energy Resources bill:
				
    
    
        
            - Affordability surcharge
- A charge required by state law to fund the gas affordability program,
            which provides assistance to low-income customers.
- CCF (100 cubic feet)
- The volume of gas measured by your gas meter.
- Cooling degree days
- A measure of the need for air conditioning (cooling) based on temperature. Cooling
        degree days are calculated by subtracting 65 degrees Fahrenheit from the average daily
        temperature.
- Customer charge
- Helps cover the costs of supplying equipment used to serve 
        customers, issuing bills and providing customer service programs.
- Energy cost adjustment
- The increase or decrease in the cost of fuel from the amount 
        included in the current rates.
- Estimate
- An estimated reading is based on actual past use, seasonal 
        trends and weather. Any difference between the estimated reading 
        and the actual one will be made up the next time the meter 
        is read.
- Gas adjustment rate (PGAC)
- Can be a credit or a charge. Adjusts the base rate for any changes in the cost of
        natural gas.
- Gas base rate
- Estimate of the annual cost of gas on a per therm basis.
        It includes the cost to contract for adequate pipeline and storage capacity. Annual
        estimated costs are spread out evenly over 12 months.
- Gas cost recovery (GCR)
- Natural gas rates are adjusted periodically because of increases and decreases 
        in the prices charged by the companies that supply the gas we deliver to you. These changes 
        are reflected on your bill as Gas Cost Recovery (GCR). We do not mark up the prices we pay 
        these suppliers for the gas.
- Gas supply acquisition charge
- The purchase and management of gas supplies for our customers, as well as the
        carrying costs of purchasing gas supplies in the summer and storing these gas supplies
        until winter.
- Gas supply service
- The purchase, transportation and storage of gas, as well as the acquisition and
        management of gas supplies for our customers; includes "gas supply acquisition service"
        and "natural gas costs."
- Heating degree days
- A measure of the need for heating based on temperature. Heating degree days are
        calculated by subtracting the average daily temperature from 65 degrees Fahrenheit.
- Late payment charge (LPC)
- Commission authorized charge of 1% per month on unpaid service balances not paid
        in full within 20 days following the issuance of the bill.
- Local distribution service
- The safe, reliable transportation of gas across
        the Minnesota Energy Resources gas distribution system to customers, including metering, billing and
        customer service; includes both "Fixed" and "Volumetric" charges to more accurately match
        the actual costs of providing these services. Fixed charges do not vary with your usage;
        Volumetric charges will vary with your usage.
- Therm
- A measurement of the amount of heat energy in natural gas, equal to 100,000 BTUs. A
        BTU, or British Thermal Unit, is the quantity of heat required to raise the temperature
        of one pound of water by one degree Fahrenheit.
