  • September 16, 2002, the Commission in its Order Approving Settlement Agreement (reference MPSC Orders page, U-13365 order) authorized NSP-W to incorporate into its Commission approved gas rate book the gas transportation tariff attached. Prior to issuance of this Commission order NSP-W did not offer transportation service but did provide sales service to two customers, Bessemer Plywood and Grand View Hospital, through special contracts that were not part of the tariffed sales service. The transportation service is available on an interruptible basis to all commercial and industrial customers who agree to: 1) curtail use of gas whenever requested by the Company, 2) shall have fuel requirements of 25,000 therms per year, or more, 3) execute a service agreement with the Company detailing terms, nomination requirements, etc. Such customers are subject to the following charges and terms and conditions of service:
    • Customer Charge per month $40.00

    • Distribution Charge per therm $0.0330
    • Unauthorized Use Penalties: If customer fails to curtail his use of gas when requested by the Company any volume of gas used in excess of the authorized volume shall be charged at the highest price reported during the curtailment period for NNG receipt point at Ventura or Demarcation as reported by Gas Daily, plus $1.00 per therm. Such gas shall be considered a sale of gas.
    • Daily Balancing - Daily Nominations: There is no additional charge for this service for imbalances up to plus or minus 5% of customers' nominated volume.

Imbalances within plus or minus 5% of the nominated amount are bought or sold at the Market Cost of Gas. Positive Imbalances greater than 5% of the nominated volumes are purchased at 0.8 times the market cost of gas, and Negative Imbalances are sold at 1.2 times the market cost of gas.

 U-10960: Michigan Gas Utilities Rate Case.
  • October 31, 1995 MGU filed an application requesting authority to increase its rates and revise its transportation tariffs, among other things.
  • March 27, 1997 the Commission issued its Opinion and Order (reference MPSC Orders page, U-10960 order, U-10960 order denying rehearing, Press Releases page, and 3/27/97 Press Release) in the rate case approving revisions to MGU's transportation tariffs. MGU's request for a daily balancing provision was denied, but the transportation tariff was restructured, and included the following features:
    • All customers are eligible to participate in the transportation program.
    • Rate classes TR-1, TR-2, and TR-3 were established. Breakeven point between TR-1 and TR-2 was set at 50,000 Mcf per year. Breakeven point between TR-2 and TR-3 is set at 225,000 Mcf.
  • Transportation Charges: TR-1 TR-2 TR-3
    Monthly Customer Charge $250 $1,160 $2,170
    Administrative Fee $450 $450 $450
    Monthly Remote Meter Charge $120 $120 $120
    Peak (Nov -Mar) Charge per Dth $0.6611 $0.4428 $0.3890
    Off-peak (APR - Oct) Charge per Dth $0.5111 $0.2928 $0.2390
    • Monthly Load Balancing: Customers may store up to 5% of their ACQ without additional charge - Authorized Tolerance Level (ATL).
    • Monthly Cashout of Positive and Negative imbalances. Positive and negative imbalances up to 5% of the monthly nomination were cashed-out at the average MichCon City Gate Index for Large End-Users for that month. Positive imbalances above 5% of monthly nominations were cashed-out at the Low price for the MichCon City Gate Index, and negative imbalances were cashed out at the High price for the MichCon City Gate Index for Large End-Users. This feature eliminated the need for an unauthorized gas usage charge.
    • Imbalance Paper Pooling Option: Any customer or customer's agent with multiple deliveries at any receipt point could pool those deliveries at that same receipt point.
    • Gas In Kind of 0.68% would be withheld to compensate the Company for lost and unaccounted for gas and company use gas.
    • No provision to allow customers to purchase system supply gas, other than the monthly cashout provision.

  U-10755: Consumers Energy Company (Consumers Power Company) rate case:
  • December 29, 1994 Consumers requested rate relief and tariff revisions.
  • March 11, 1996, the Commission issued its final order (reference MPSC Orders page, U-10755 Order, U-10755 Order denying rehearing) which, among other things provided:
    • Transportation tariffs T-1 and T-2 were split to create Rates ST-1 and ST-2 for transportation customers using less than 100,000 Mcf per year, and Rates LT-1 and LT-2 for transportation customers using more than 100,000 Mcf per year.
    • ST and LT rates retained the same basic provision and rate structure as the predecessor tariffs including:
            ST LT
          Monthly Customer Charge $750 $1,350
    • Monthly Load Balancing (Storage): Customers are still entitled to store up to 8.5% of ACQ (Authorized Tolerance Level), but injections were restricted to 1.43% of ACQ during September and October and withdrawals were restricted to 3% of ACQ during November through March of each year. Gas in storage above the ATL ( 8.5% of ACQ) will be charged a storage rate of $0.25 per Mcf, or Consumers may require the customer to reduce its balance to ATL.
    • System Supply Entitlement Charge option was retained, although seldom used.
    • Use and Loss: Gas in Kind was set at 1.03% of gas delivered.
    • Aggregation of Accounts provision was adopted. Option A allowed contiguous facilities, under a common ownership, and operated as a unitary enterprise to be treated as a single account for billing purposes. This meant that only one customer charge would be applied. Option B allowed multiple facilities under a common ownership to aggregate the gas supplied to the facilities for billing purposes if; one of the facilities, designated as the master account, would be served under a transportation tariff, and the remaining facilities, designated as subsidiary accounts, were taking service under a sales tariff. The subsidiary accounts would be billed as sales accounts, excluding the GCR Factor. Remote metering was not required for any of the accounts.
    • Contract Storage Rate tariff was approved to allow customers to contract for additional storage service as they needed it. The rate was $300 per month plus a demand and commodity charge from $0.20 per Mcf up to $1.50 per Mcf as negotiated between the Consumers and the customer.

  U-10150: Michigan Consolidated Gas Company Rate Case:

  • September 1, 1992 MichCon requested rate relief and tariff revisions.
  • October 28, 1993 the Commission issued its final order (reference MPSC Orders page, U-10150 Order, U-10150 order denying rehearing) in the rate case, which included the following:
    • Transportation tariffs T-1 and T-2 were split to create Rates ST-1 and ST-2 for transportation customers using less than 100,000 Mcf per year, and Rates LT-1 and LT-2 for transportation customers using more than 100,000 Mcf per year.

    ST and LT rates retained the same basic provision and rate structure as the predecessor tariffs including:

          ST LT
        Monthly Customer Charge $1,300 $2,100
    • Monthly Load Balancing (Storage): Customers are still entitled to store up to 10% of ACQ, but injections were restricted to 1.43% of ACQ during September and October and withdrawals were restricted to 3% of ACQ during November through March of each year. Gas in storage above 10% of ACQ will be charged a storage rate of $0.25 per Mcf, or MichCon may require the customer to reduce its balance to 10% of ACQ.
    • System Supply Entitlement Charge option was eliminated.
    • Use and Loss: Gas in Kind was reduced from 1.78% to 0.9% of gas delivered.
    • Contract Storage Rate tariff was approved to allow customers to contract for additional storage service as they needed it. The rate was $300 per month plus a demand and commodity charge up to $1.50 per Mcf as negotiated between the MichCon and the customer. [FERC required that the ceiling on this rate be set at the cost of service since MichCon could offer this to interstate customers]
