97.6.1 5th Revision 97.6.1 4th Revision Factors History Chugach is requesting Commission approval of the methodology identified herein to establish unified (CPCN Nos. 121 and 8) fuel rates, purchased power rates, and the Fire Island Wind Renewable Energy Adjustment Factor for retail deliveries at primary and secondary voltage.1 As this request is for methodological approval only, Chugach is not proposing any rate adjustments with this filing and does not request approval of the tariff sheets submitted herewith for inclusion in its tariff. Rather, the information submitted herein is used as the basis to establish the underlying methodology for determining fuel and purchased power rates as a combined system under CPCN Nos. 8 and 121. In this filing, all the attached tariff sheet have been marked “For Approval of Methodology Only” for clarity. Based on Commission approval of the proposed methodology in this filing, Chugach will submit its fuel and purchased power filing reflecting the acquisition of ML&P by November 17, 2020 for rates effective January 1, 2020. This filing is not for a new service, will not result in the termination of an existing service, conflict with any other schedule or rate contained in Chugach’s operating tariff, or in any other way adversely impact customers or the public. The service areas under CPCN Nos. 121 and 8 are designated in this filing as the North District and South District respectively. Approximately 113,225 retail metered locations and wholesale customer Seward Electric System (Seward) are impacted by this filing, with 31,225 retail metered locations in CPCN 121 and approximately 82,000 retail and wholesale metered locations in CPCN 8. On a preliminary basis, Chugach is projecting annual revenues of approximately $325 to $350 million for calendar-year 2021.2 Order 39 required Chugach to include in its quarterly fuel and purchased power rate adjustment process the Restricted Rate Reduction (“RRR”) account rebate and the Beluga River Unit (“BRU”) Contributed Capital surcharge and rebate, which were submitted to the Commission on August 26, 2020 under Tariff Advice Nos. 492-8 and 493-8, respectively. These two tariff filings request Commission approval of the methodology for these factors; however, once the methodology is approved, the tariff sheets and supporting exhibits for the calculation of the surcharge and rebates will be updated and submitted to the Commission as part of Chugach’s quarterly fuel and purchased power rate adjustment process. Chugach has included a new tariff sheet in this filing, attached as Tariff Sheet No. 94.1.2, that summarizes the quarterly RRR rebate surcharge, the BRU

1 Fuel and purchased power costs assigned to the City of Seward are recovered on an actual cost basis rather than on a rate basis. Chugach is not proposing any changes to this cost recovery approach. 2 The projections are preliminary and subject to change as Chugach is developing 2021 forecasts. When including the Restricted Rate Reduction rebate, the Beluga River Unit Contributed Capital surcharge and rebate, the combined BRU GTP and the combined fuel and purchased power rates, the estimated impact to a monthly residential customer bill based on 600 kWh is a reduction of approximately 6 to 9 percent. These estimated impacts will be updated in Chugach’s mid-November 2020 filing to the Commission.

Contributed Capital surcharge and rebate, and the combined system fuel and purchase power rates calculated herein. The surcharge, rebates and fuel and purchased power rates summarized on this sheet will not be implemented but instead are shown to illustrate how the information will be provided to the Commission in the future. For billing purposes, the RRR rebate, the BRU Contributed Capital surcharge and rebate, and the fuel and purchased power rates will be separate line items on each customer bill. Chugach has structured this filing in two sections. Section I presents the detailed methodology for establishing unified rates for the recovery of all fuel and purchased power costs. This section also includes a description of the changes within each exhibit and tariff sheet used to develop the rates. Section II summarizes how Chugach expects to transition from the recovery of fuel and purchased power costs as separate entities to the recovery of costs as a unified system, and how its initial combined fuel and purchased power rate recovery filing will be structured. Section I: Methodology for Establishing Unified Fuel and Purchased Power Rates As a combined system under CPCN Nos. 8 and 121, Chugach is proposing to continue the use of its established methodology for the recovery of fuel and purchased power costs. Chugach’s recovery of these costs is completed on an average cost basis, with rates reflecting deliveries at primary and secondary service. Three rate components are used for the recovery of these costs: the fuel rate, the purchased power rate, and the Fire Island Wind Renewable Energy Adjustment Factor. Chugach is proposing to adopt this rate and recovery structure for all retail customers on the combined system such that all customers served at primary voltages pay the same rate and all customers served at secondary voltages pay the same rate, regardless of location. The fuel rate includes the cost of natural gas, gas transportation and gas storage. The purchased power rate includes the cost of Bradley Lake purchases, purchases from other Railbelt utilities, and purchases from qualified facilities. The Fire Island Wind Renewable Energy Adjustment Factor provides recovery of the incremental cost of purchases from the Fire Island Wind project. In contrast, ML&P recovers its fuel and purchased power costs through a single Cost of Power Adjustment (“COPA”) factor, adjusted to reflect delivery at primary and secondary voltage. Explanation of Exhibits: Fuel and Purchased Power Cost Recovery Chugach has updated the exhibits used in the determination of its quarterly fuel and purchased power rates to reflect Chugach’s acquisition of ML&P and the resultant combined operations and recovery of fuel and purchased power costs on a unified basis. The cost and sales information used to develop unified rates are based on actual first quarter 2020 results and projections through third quarter 2020, with adjustments as noted.3 Below is an explanation of the changes made to each of Chugach’s exhibits used in its quarterly fuel and purchased power rate adjustment process, and the creation of a new exhibit that has information previously shown on an existing Chugach tariff sheet. • Exhibit 1 – Projections: Exhibit 1, pages 1 through 3, presents projections for system fuel

and purchased power expenses, and generation and purchased power requirements (MWh)

needed to meet the combined system load requirements. The projections in this exhibit are used in the rate determinations on Tariff Sheet Nos. 94 through 94.05.

As indicated above, under a system average cost methodology, Chugach has combined all fuel and purchased power costs and generation requirements to meet the combined system load of Chugach and ML&P.4 Chugach has modified this exhibit by incorporating the generation and purchased power requirements previously met by ML&P under CPCN 121. Specifically, Plant 1, 2 and 2A have been added to each fuel supply source; fuel storage and transportation costs have been combined, as have the costs and production levels associated with the BRU.5 Overall, combined expenses include natural gas purchases from Hilcorp, Furie, and other gas producers, gas transportation costs, gas storage costs, and purchases from Bradley Lake, and purchases from qualified facilities and other Railbelt utilities. Wheeling and economy energy sales transactions between Chugach and ML&P have been removed as these transactions will no longer exist, post-acquisition.

Development of the allocation factors shown on page 4 of Exhibit 1 have been expanded to include customers currently served under CPCN 121.

• Exhibit 2 – MWh Sales: Exhibit 2 presents MWh sales by retail and wholesale rate class for

the 12-months ended March 2020. Chugach has added the residential, small commercial, large commercial and lighting classes previously served under CPCN 121 to this exhibit. Also included are sales to Golden Valley Electric Association, Inc. (“GVEA”), Homer Electric Association, Inc. (“HEA”) and Matanuska Electric Association, Inc. (“MEA”). Economy energy sales transactions between Chugach and ML&P have been removed from this exhibit. This exhibit also calculates system losses using the prior 12-month period, based on MWh sales and generation / purchased power levels.

• Exhibit 3 – Generation: Exhibit 3 presents generation and purchased power levels for the

12-months ended March 2020. Chugach has added Plant 1, Plant 2 and Plant 2A, ML&P’s 30 percent interest in the Southcentral Power Project, and ML&P’s purchases from Bradley Lake, qualified facilities and the Eklutna Hydro Project to this exhibit. Transactions between Chugach and ML&P are excluded.

• Exhibit 4 – Natural Gas Usage (Mcf): Exhibit 4 presents the natural gas usage by unit for

each power plant. Chugach has added Plant 1, Plant 2 and Plant 2A to this exhibit, and has included both Chugach and ML&P gas in the reported figures for the Southcentral Power Project.

• Exhibit 5 – Wheeling, Economy Sales and Other Revenue: Exhibit 5 summarizes economy

sales transactions and other revenues that are applied as offsets to fuel and purchased power costs to be recovered by customers. For the acquisition, this exhibit has been modified to reflect ML&P economy transactions and water sales to Anchorage Water and Wastewater

4 ML&P currently has an interruptible gas contract with Hilcorp Alaska. Post-acquisition, Chugach’s purchases of gas from Hilcorp will be made under its existing contract approved by the Commission in Tariff Advice No. 481-8. 5 The methodology for determination of the BRU gas transfer price under Chugach’s ownership was filed with the Commission in Tariff Advice No. 494-8 on August 26, 2020.

Utility (“AWWU”). AWWU purchases water from Eklutna Lake under ML&P Rate Schedule 25 and Chugach will continue the existing credit methodology.

ML&P wheeling to GVEA is included in this exhibit, but in future filings, this category will become Chugach wheeling to GVEA. Economy sales transactions are shown on pages 2 through 5, and such transactions between Chugach and ML&P were removed from the exhibit.

• Exhibit 6 – Fuel and Purchased Power Expenses: Exhibit 6 presents a summary of monthly

fuel and purchased power costs for combined operations in the quarter. As explained below, the exhibit includes a fuel expense section and a purchased power expense section.

The fuel expense section identifies fuel purchased from each gas supplier and the generation facility where the fuel was used. For the acquisition, Chugach has added ML&P’s share of Cook Inlet Natural Gas Storage Alaska (“CINGSA”) (FSS and ISS), and fuel and transportation costs for Plant 1, Plant 2, and Plant 2A.

In the purchased power section, costs for energy transactions between Chugach and ML&P have been removed and the Bradley Lake and Intertie expenses were combined. Because Chugach treats the gas that it sends to other utilities for purchased generation as a purchased power expense, the gas sent to ML&P for power purchased has been added to plant 2A for each fuel source.

• Exhibit 7 – Balancing Account: Exhibit 7 provides the balancing account balances for fuel

and purchased power as of March 31, 2020, and projected balancing account balances through June 30, 2020. The actual and projected balancing account balances have been expanded to include the residential, small commercial, large commercial and lighting rate classes under CPCN 121.

• Exhibits 8 through 10 – Cost Assignment: Exhibits 8 through 10 allocate the fuel and

purchased power costs to the rate classes based on the allocators developed on page 1 of Exhibits 8, 9 and 10. Chugach has added the residential, small commercial, large commercial and lighting rate classes previously served under CPCN 121 to each exhibit. These exhibits also reflect the revenue offsets (economy margins, wheeling revenue, exchange revenues, etc.) of the combined system as presented on Exhibit 5. Chugach will update the loss factors to reflect the combined system with its annual update to the G&T and Distribution loss factors that will be submitted to the Commission as a tariff advice filing by March 15, 2021.

• Exhibit 11 – Gas in Storage: Exhibit 11 provides detailed information, over an 18-month

period, of the gas in storage at CINGSA. The calculations on this exhibit provide the cumulative totals for the volumes and value of gas in storage and the calculated weighted average cost of gas (“WACOG”) in storage.

Chugach does not have historical information regarding ML&P’s gas in storage. After the utilities have integrated, the fuel stored in CINGSA by both Chugach and ML&P will be combined and the new WACOG will be calculated. A new page has been added to this exhibit to provide volumes and average cost of gas in storage for ML&P on March 31, 2020.

Commissioners August 26, 2020 Tariff Advice No. 495-8 Page 6 of 9

• Exhibit 12 – Gas Volumes and rates by Power Plant (Projected and Actual): This is a new exhibit. This exhibit provides the detail for natural gas used at each power plant by fuel contract for both projected and actual usage that was formerly presented on Tariff Sheet Nos. 94, 95, and 95.5. Included in this exhibit is the detail of natural gas volumes and price by contract used to generate electricity, and projected to be used, for each power plant on the combined Chugach system (Plant 1, Plant 2 and Plant 2A have been added to this exhibit). This exhibit also includes fuel used, and projected to be used, at MEA’s Eklutna Generation Station (“EGS”) power plant under the Amended and Restated Operations Agreement for Power Pooling and Joint Dispatch.

• Reserved for November 2020 Filing - Exhibits 13 and 14: Exhibits 13 and 14 will be added

to Chugach’s fuel and purchased power rate adjustment filings beginning with the initial post-acquisition filing following close. The content of Exhibits 1 and 2 submitted to the Commission on August 26, 2020 under Tariff Advice No. 492-8 present the calculation of the rebate and balancing account activity for the North District Restricted Rate Reduction Account. These will be Exhibits 13 and 14 in future fuel purchased power rate adjustment filings, post-acquisition.

• Reserved for November 2020 Filing - Exhibits 15, 16 and 17: Exhibits 15 through 17 will

be added to Chugach’s fuel and purchased power rate adjustment filings beginning with the initial post-acquisition filing following close. The content of Exhibits 1 through 3 submitted to the Commission on August 26, 2020 under Tariff Advice No. 493-8 present the calculation of the surcharge and rebate and balancing account activity associated with the BRU Contributed Capital adjustment. These will be Exhibits 15 through 17 in future fuel purchased power rate adjustment filings, post-acquisition.

Explanation of Tariff Sheet Changes: Fuel and Purchased Power Cost Recovery Chugach has modified its tariff sheets to include actual and projected costs and revenues for combined operations. Each tariff sheet also includes text identifying the results as “Post-Acquisition,” and other necessary changes as described below. Chugach is not requesting Commission approval of any of the rates contained on these tariff sheets. Tariffs that contain rates for implementation will be submitted to the Commission by November 17, 2020 for rates effective January 1, 2021. The format of tariff sheets in this filing have been updated according to 3 AAC 48.330.

• Tariff Sheet No. 94: The projected costs and sales figures on this tariff sheet have been updated to reflect combined operations. Due to space limitations on this tariff sheet, the detail for projected natural gas for each power plant on the combined system has been moved to an exhibit and replaced with summarized projected gas expense by contract and class. The detail by power plant, which includes the addition of Plant 1, Plant 2, and Plant 2A, is now presented on Exhibit 12. Additional revisions to this tariff sheet include clarifying text changes. The sheet title now includes the words “Post Acquisition.” The line “Emergency Generator Fuel” has been revised to read, “Emergency Generator and Other Diesel Fuel,” and the line “CINGSA – FSS, ISS and Gas Withdrawn,” is now presented in two separate lines, “CINGSA – FSS/ISS Capacity and Withdrawal Fees” and “CINGSA – Gas Withdrawn.”

Incremental Fire Island Wind Adjustment Factor: Predicted costs for the quarter beginning July 1, 2020,” has been broken into two lines. The first line now reads, “e.3. Incremental Fire Island Wind Adjustment Factor:” and the second line is, “Predicted costs for the quarter beginning July 1, 2020.” Additionally, the line that formerly read, “e.4. Summary of fuel and purchased power cost adjustment factors at G&T for rates effective July 1, 2020,” has been broken into two lines that read, “e.4. Summary of fuel and purchased power cost adjustment factors at G&T,” and “for rates effective July 1, 2020.”

• Tariff Sheet Nos. 94.1 and 94.1.1: The rates presented on these tariff sheets reflect

combined operations. Other changes to this tariff sheet include text changes. The sheet title now includes the words “Post Acquisition,” and “(b / c)” has been removed from the end of lines A. (d), B. (d) and C. (d) in section 5.

• Tariff Sheet No. 94.1.2: This new tariff sheet has been added to present the summary fuel, purchased power, Fire Island Wind Renewable Energy Adjustment Factor, Restricted Rate Reduction rebate, and BRU Contributed Capital rebate and surcharge rates for the North and South districts at primary and secondary delivery.

• Tariff Sheet No. 95: The costs and sales figures on this tariff sheet have been updated to reflect combined operations. Due to space limitations on this tariff sheet, the detail for actual natural gas for each power plant on the combined system has been moved to an exhibit and replaced with summarized actual gas expense by contract and class. The detail by power plant, which includes the addition of Plant 1, Plant 2, and Plant 2A, is now presented on Exhibit 12. Additionally, “Post Acquisition” has been added to the title of this sheet.

• Tariff Sheet and 95.04: The costs and sales figures on this tariff sheet have been updated to reflect combined operations. “Post Acquisition” has been added to the title of this sheet, and the line that formerly read “Wheeling Revenue,” has been revised to “Wheeling and Other Revenue.”

projected costs on a total and unit cost basis. Additionally, the detail for predicted and actual natural gas used, by power plant, has been relocated to Exhibit 12 and replaced with the summary totals of predicted and actual natural gas to be used by contract. The price per Mcf for BRU gas is a blended rate which is calculated based on the volumes and price for each district. Deleted lines include: the line “Gas Exchange Contributions (Tesoro and Furie)” and CINGSA – ISS Capacity and Withdrawal Fees.” A new line was added, “Emergency Generator and Diesel Fuel,” and the Text that previously read “CINGSA – FSS Capacity and Withdrawal Fess,” has been modified to read, “CINGSA – FSS and ISS Fees. Additionally, the sheet title has been revised to include the words, “Post Acquisition.”

• Tariff Sheet No. 97: Chugach has proposed the continued use of its established methodology to calculate avoided cost rates for purchases at primary and secondary voltages for customers in both the North District and South District. Chugach notes that the rates under CPCN 8 are available for non-utility generation containing a nameplate capacity of 200 kW or less, whereas the rates under CPCN 121 are available for non-utility generation of 100 kW or less. Post-acquisition, Chugach is proposing that the rate for purchases from qualified facilities be available for non-utility generation containing a nameplate capacity of 200 kW or less. The text change on this tariff sheet is the addition of the words, “Post Acquisition,” to the sheet title.

• Tariff Sheet Nos. 97.1.4, 97.5.2 and 97.6.1: The rates summarized on this sheet beginning January 1, 2021 include the combined operations for fuel, purchased power, and the Fire Island Wind Renewable Energy Adjustment Factor. New lines have been added to denote the transition point from separate entities to post acquisition results.

Section II: Transition to Unified Fuel and Purchased Power Rates Pursuant to Order 39, Chugach will submit its initial fuel and purchased power filing by November 17, 2020, for implementation of rates for actual billing on January 1, 2021. This first combined fuel and purchased power filing will serve primarily as a transitional filing and will include the tariff sheets and supporting exhibits for the RRR account rebate to North District customers, the BRU Contributed Capital surcharge to South District customers, the BRU Contributed Capital rebate to North District customers, and unified fuel and purchased power rates for the recovery of system fuel and purchased power costs. In mid-November 2020, Chugach will also submit its updated BRU gas transfer price. In recognition of the October 30, 2020 closing date, fuel and purchased power rates effective January 1, 2021 will be based on projected combined costs from October 30, 2020 through March 31, 2021 and estimated fuel and purchased power balancing account balances from Chugach and ML&P as of October 30, 2020. The balancing account balances will be reconciled with actual account balances once the costs and revenues through October 30, 2020 have been finalized. At a minimum, Chugach will include actual costs and revenues through September 30, 2020 under CPCN 8. Chugach has requested that ML&P provide actual costs and revenues through September 30, 2020. October 2020 balances for each utility will be estimated. Differences between estimated and actual costs and revenues will be factored into the balancing account in subsequent quarterly filing. The Chugach and ML&P balancing accounts will be combined and balances will be factored into the determination of unified system rates.

1 Chugach losses between primary and secondary delivery are 0.7504 percent as measured from secondary (Docket U-06-134). Chugach used its line loss factors for ML&P's sales data in this filing

.

Chugach will update the combined system loss factors with its Generation and Transmission Loss Factor update to be filed in June 2020.2 ML&P sales by rate class projections were derived by taking the total projected sales from their COPA filing and allocating this amount across the rate classes based on the percentage of actual sales

reported by rate class. Going forward, these projections will be based on Chugach’s forecast for sales from the North and South Districts.

Losses: Total Percent

Retail 79,156 14.5%

Transmission 377 2.5%

System 79,533 14.2%

Water Sales Revenue $44,791 $40,423 $46,849 $132,0641 Rate at primary delivery is the rate that was in effect first quarter 2020. Alaska Water and Waste Utility (AWWU) purchases water from Eklutna Lake through ML&P under Schedule 25 of ML&P's Tariff.

The calculation of the revenues from the sale of water to AWWU, presented on page 1 of Exhibit 5, is based on water sales converted to kWh’s multiplied by the primary fuel rate in effect. The calculation

methodology is the same methodology used in ML&P’s COPA filing on Attachment No. 4.1 on lines 24 through 26
