(k)           Procedure for Rate Adjustments Under G.S. 62-133.4.

(1)           Purpose. The purpose of this Section (k) of Rule R1-17 is to set forth the procedures by which local distribution companies can file to adjust their rates pursuant to G.S. 62-133.4. The intent of these rules is to permit LDCs to recover 100% of their prudently incurred gas costs applicable to North Carolina operations.

(2)           Definitions. As used in this Section (k) of Rule R1-17, the following definitions shall apply:

(a)           "LDC" shall mean local distribution company.

(b)           "Gas Costs" shall mean the total delivered cost of gas paid or to be paid to Suppliers, including, but not limited to, all commodity/gas charges, all direct, transaction-related costs arising from an LDC’s prudent efforts to stabilize or hedge commodity gas costs, demand charges, peaking charges, surcharges, emergency gas purchases, over-run charges, capacity charges, standby charges, reservation fees, gas inventory charges, minimum bill charges, minimum take charges, take-or-pay charges, storage charges, service fees and transportation charges, and other similar charges in connection with the purchase, storage or transportation of gas for the LDC's system supply.

(c)           "Suppliers" shall mean any person or entity, including affiliates of the LDC, who locates, produces, purchases, sells, stores and/or transports natural gas or its equivalent for or on behalf of an LDC, or who provides hedging tools, including, but not limited to financial tools, designed to stabilize the LDC’s commodity prices. Suppliers may include, but not be limited to, interstate pipeline transmission companies, producers, brokers, marketers, associations, intrastate pipeline transmission companies, joint ventures, providers of Liquified Natural Gas, Liquified Petroleum Gas, Synthetic Natural Gas and other hydrocarbons used as feed stock, other LDCs and end-users.

(d)           "Benchmark Commodity Gas Costs" shall mean an LDC's estimate of the City Gate Delivered Gas Costs for long-term gas supplies, excluding Demand Charges and Storage Charges as approved in the LDC's last general rate case or gas cost adjustment proceeding. The Benchmark Commodity Gas Costs may be amended from time to time as provided in Section (k)(3)(a).

(e)           "City Gate Delivered Gas Costs" shall mean the total delivered Gas Costs to an LDC at its city gate.

(f)            "Commodity and Other Charges" shall mean all Gas Costs other than Demand Charges and Storage Charges and any other gas costs determined by the Commission to be properly recoverable from sales customers.

(g)           "Demand Charges and Storage Charges" shall mean all Gas Costs which are not based on the volume of gas actually purchased or transported by an LDC and any other gas costs determined by the Commission to be properly recoverable from customers.

(3)           Rate Adjustments Under these Procedures.

(a)           Sales Rates. In the event an LDC anticipates a change in its City Gate Delivered Gas Costs, the LDC may apply and file revised tariffs in order to increase or decrease its rates to its customers as hereinafter provided. The Commission may issue an order allowing the rate change to become effective simultaneously with the effective date of the change or at any other time ordered by the Commission. If the Commission has not issued an order within 120 days after the application, the LDC may place the requested rate adjustment into effect. Any rate adjustment under this Section (k)(3)(a) is subject to review under Section (k)(6).

(i)            Demand Charges and Storage Charges. Whenever an LDC anticipates a change in the Demand Charges and Storage Charges, the LDC may (as hereinabove provided) change its rates to customers under all rate schedules by an amount computed as follows:

[(Total Anticipated Demand Charges and Storage Charges - Prior Demand Charges and Storage Charges) X NC Portion*]/ Sales & Transportation Volumes* = Increase (Decrease) Per Unit

*Established by the Commission in the last general rate case.

(ii)           Commodity and Other Charges. Whenever the LDC's estimate of its Benchmark Commodity Gas Costs changes, an LDC may (as hereinabove provided) change the rates to its customers purchasing gas under all of its sales rate schedules by an amount computed as follows:

{[Volumes of gas purchased* (excluding Company Use and Unaccounted For) X (New Benchmark Commodity Gas Costs - Old Benchmark Commodity Gas Costs)] X NC Portion*}/ {Volumes of gas purchased for System Supply* (excluding Company Use and Unaccounted For)* X NC Portion*} = Increase (Decrease) Per Unit

*Established by the Commission in the last general rate case

(b)           Transportation Rate.  Firm and/or interruptible transportation rates shall be computed on a per unit basis by subtracting the per unit Commodity and Other Charges included in the applicable firm or interruptible sales rate schedule from the applicable firm or interruptible rate schedule exclusive of any decrements or increments. Commodity deferred account increments or decrements shall not apply to transportation rates unless the Commission specifically directs otherwise.  Demand and storage increments or decrements shall apply to transportation rates.

(c)           Other Changes in Purchased Gas Costs.  The intent of these procedures is to permit an LDC to recover its actual prudently incurred Gas Costs. If any other Gas Costs are incurred, they will be handled as in Section (3)(a)(i) if they are similar to Demand Charges and Storage Charges, or as in Section (3)(a)(ii) if they are similar to Commodity and Other Charges.

(4)           True-up of Gas Costs.

(a)           Demand Charges and Storage Charges. On a monthly basis, each LDC shall determine the difference between (a) Demand Charges and Storage Charges billed to its customers in accordance with the Commission-approved allocation of such costs to the LDC's various rate schedules and (b) the LDC's actual Demand Charges and Storage Charges. This difference shall be recorded in the LDC's deferred account for demand and storage charges. Increments and decrements for  this deferred account, including the portion of the Commodity and Other Charges true-up calculated under Section (4)(b) and apportioned to this deferred account, flow to all sales and transportation rate schedules. Where applicable, the percentage allocation to North Carolina shall be the percentage established in the last general rate case. 

(b)           Commodity and Other Charges. On a monthly basis, each LDC shall determine with respect to gas sold (including company use and unaccounted for) during the month the difference between (a) the actual Commodity and Other Charges incurred and (b) the actual Commodity and Other Charges billed to customers.  This difference shall be apportioned each month to the LDC's deferred account for commodity and other charges based on the ratio of volumes sold to the volumes purchased for that month.  The residual portion of the difference not apportioned to the LDC’s deferred account for commodity and other charges shall be apportioned each month to the LDC’s deferred account for Demand Charges and Storage Charges.  Increments and decrements for Commodity and Other Charges flow to all sales rate schedules.

(c)           Repealed.

(d)           Supplier Refunds and Direct Bills.  In the event an LDC receives supplier refunds or direct bills with respect to gas previously purchased, the amount of such supplier refunds or direct bills will be recorded in the appropriate deferred account, unless directed otherwise by the Commission.

(5)           Other.

(a)           Gas Costs changes not tracked concurrently shall be recorded in each LDC's appropriate deferred account.

(b)           The Commodity and Other Charges portion of gas inventories shall be recorded at actual cost and the difference in that cost and the cost last approved under Section (k)(3)(a)(ii) shall be recorded in the deferred account when the gas is withdrawn from inventory.

(c)           Each LDC shall file with the Commission (with a copy to the Public Staff) a complete monthly accounting of the computations under these procedures, including all supporting workpapers, journal entries, etc., within 45 days after the end of each monthly reporting period. All such computations shall be deemed to be in compliance with these procedures unless within 60 days of such filing the Commission or the Public Staff notifies the LDC that the computations may not be in compliance; provided, however, that if the Commission or the Public Staff requests additional information reasonably required to evaluate such filing, the running of the 60 day period will be suspended for the number of days taken by the LDC to provide the additional information.

(d)           Periodically, an LDC may file to adjust its rates to refund or collect balances in these deferred accounts through decrements or increments to current rates. In filing for an increment or decrement, the LDC shall state the amount in the deferred account, the time period during which the increment or decrement is expected to be in effect, the rate classes to which the increment or decrement is to apply, and the level of volumes estimated to be delivered to those classes. Any such increments or decrements shall be made on a flat per dekatherm basis for all affected rate classes, unless otherwise ordered by the Commission.

(e)           Notwithstanding the provisions of this Rule, an LDC may offset negotiated losses in any manner authorized by the Commission.

(6)           Annual Review.

(a)           Annual Test Periods and Filing Dates.  Each LDC shall file and submit to the Commission the information required in Section (k)(6)(c) for an historical 12-month test period. This information shall be filed by Toccoa Natural Gas on or before September 1 of each year based on a test period ended June 30. This information shall be filed by Frontier Natural Gas, LLC, on or before December 1 of each year based on a test period ended September 30.

(b)           Public Hearings.  The Commission shall schedule an annual public hearing pursuant to G.S. 62-133.4(c) in order to compare each LDC’s prudently incurred Gas Costs with Gas Costs recovered from all its customers that it served during the test period.  The public hearing for Toccoa Natural Gas shall be on the first Wednesday of November.  The public hearing for Frontier Natural Gas, LLC, shall be on the first Tuesday of March.  The public hearing for Piedmont Natural Gas Company, Inc., shall be on the first Tuesday of October.  The public hearing for Public Service Company of North Carolina, Inc., shall be on the second Tuesday of August.  The Commission, on its own motion or the motion of any interested party, may change the date for the public hearing and/or consolidate the hearing required by this section with any other docket(s) pending before the Commission with respect to the affected LDC.

(c)           Information Required in Annual Filings. Each LDC shall file information and data showing the LDC's actual gas costs, volumes of purchased gas, weather-normalized sales volumes, sales volumes, negotiated sales volumes and transportation volumes and such other information as may be directed by the Commission. All such information and data shall be accompanied by workpapers and direct testimony and exhibits of witnesses supporting the information.

(d)           Notice of Hearings. Each LDC shall publish a notice for two (2) successive weeks in a newspaper or newspapers having general circulation in its service area, normally beginning at least 30 days prior to the hearing, notifying the public of the hearing before the Commission pursuant to G.S. 62-133.4 and setting forth the time and place of the hearing.
