City Council Agenda Statement Meeting Date: November 13,2023 To: City Council Through: Kat Sorensen,City Manager From: Rob Montgomery, General Manager Electric Utility Subject: Resolution 2023-120: Amending The 2024 Electric Rates Tariff To Incorporate Recommendations From The 2023 Rate Study To Set Electric Rates At A Level To Meet The Utility's Revenue Requirements Over The Next Three Years Background and justification: The successful operation of an electric utility requires the ability to resolve several interrelated,yet conflicting,goals. Central to these goals are rates. Set too high, and the utility risks losing load,or even entire customers,to self-generation. But setting rates too low reduces the financial health of the utility or runs the risk of not being able to keep up with maintenance and potential reliability issues. Low rates can also lead to insufficient revenues for retaining key personnel or filling all staff positions. Seward's electric utility is currently facing several financial challenges. The first is the payment of the $10 million revenue bond that was taken out in 2022 to pay for deferred maintenance related to infrastructure (Nash Road and substations).The utility begins paying the principal payment on the bond in 2024,which is almost$1 million annually. The utility also has unbudgeted infrastructure work to complete in the refurbishment of the Spring Creek Substation and several other capital projects on the books over the next three years,including the replacement of old and deteriorating underground cable serving residential areas such as Stoney Creek, Gateway/Dora Way, Old Mill,Nash Woods, and Questa Woods. These projects are critical to providing these communities with reliable service. Additionally,the utility must also meet forthcoming reliability and cybersecurity standards being set by the state of Alaska;manage expenses related to deferred and ongoing maintenance; cope with the rising costs of materials and supplies and inflation in general; ensure adequate cash flow related to debt service coverage ratios and add necessary resources to adequately operate the utility moving forward. Seward's rate study was conducted by Mike Hubbard of the Financial Engineering Company. Mr. Hubbard is an expert with 44 years of experience in ratemaking. The recommended adjustments in rates are based upon a"cost of service" allocation,meaning the "cost causer"is the"cost payer." City Council conducted a work session on the rate study on September 11, and input was received from the public during the session. Some adjustments to Mr.Hubbard's study (outlined below)were made, where practical,based on Council and public feedback.While these changes lowered the overall target margin,labor costs and the contribution to the Major Repair and Replacement Fund(MRRF),one expense was also added to the study that was not known until after the work session. This was an expense related to shared right-of-way maintenance with Chugach Electric for the line between Cooper Landing and Moose Pass. Below are the updates made to the study following the September 11 work session: 186 1. Decreased the rate study's target margin from $500,000 to $300,000, which aligns with the utility's target margin established in the 2021 rate study. 2. Decreased the rate study's MRRF contribution from $500,000 to $350,000. 3. Decreased the rate study's labor expenses on the proposed organizational chart from $835,000 to $675,000.This reduction was the result of eliminating the Apprentice Operator position and combining the Government/Railbelt Relations Coordinator and the Customer Relation-Communications Coordinator into one job. 4. Increased the rate study $700,000 total ($400,000 in 2024 and $300,000 in 2026) to maintain the transmission line right-of-way between Chugach Electric's Dave's Creek Substation near Cooper Landing to Seward Electric's Lawing Substation near Moose Pass. Seward owns the high-voltage transmission lines and poles within the right-of-way and CEA owns the lower voltage distribution lines attached to the same poles. The 2023 Rate Study recommends an increase in rates of $0.06 across all customer classes beginning January 1, 2024. This adjustment to Seward's rates will result in an overall increase of$36.00/month for residential customers using an average of 600kWh/month.

INTRODUCTION BACKGROUND The successful operation of an electric utility (or any type of utility for that matter) requires the resolution of several interrelated, yet conflicting, goals. Central to these goals are rates. Set too high, and the utility risks losing load, or even entire customers, to self-generation. But setting rates too low reduces the financial health of the utility or runs the risk of not being able to keep up with maintenance and potential reliability issues. Low rates can also lead to insufficient revenues for retaining key personnel or filling all staff positions. Setting rates too low for short periods can also lead to long-term problems. Too often, "temporary" reductions in budgets that forego maintenance become the norm. By the time maintenance becomes critical, large rate increases are required to bring the utility back to safe and reliable operations. All of these issues, whether influenced by high rates or low rates, can lead to ratepayer discontent. If this discontent is strong enough, the sale of the utility becomes a strong possibility. Here in Alaska, Chugach Electric's acquisition of Anchorage Municipal Light 8s Power is the most recent example. Other examples exist, however, including Golden Valley Electric Association acquiring the electric utility of Fairbanks Municipal Utilities System, the City of Thorne Bay selling its utility to Alaska Power Company, and the Alaska Village Electric Cooperative acquiring Bethel Utilities and others. Clearly, rate setting is no easy task, and both long- and short-term factors must be taken into account. Thus when setting rates, budgets should be established that consider the various activities required over the next several years. In addition to on-going operations, the budget must consider: • Prudent Maintenance. While it is sometimes easy to forego right-of-way clearings and other similar activities that are not required immediately, foregoing these can lead to increased damage during storm events or playing "catch-up" later on. Sporadic maintenance may also lead to higher costs if the work must be contracted out due to existing staff being busy with other work. • Emerging Technologies. Sufficient working capital is required to implement capital improvements or programs that provide near- and long-term benefits to consumers. • Security. Both cyber security and security for the infrastructure are now of more importance and must be part of any budget. I. Introduction Page 1 196 • Staffing. Adequate staffing levels for safe and reliable operations must be included. With emerging technologies and security becoming more important, historic staffing levels may no longer be adequate. Staff positions that are included in the budget but remain unfilled are a strong indication that budgeted salary levels are inadequate to attract qualified personnel. • Debt Covenants. Lenders to municipal utilities such as Seward require minimum cash flows be maintained through specified debt service coverage ("DSC") ratios. Even if there is no debt, minimal cash flows might restrict access to future debt. • Impact on Ratepayers. All the above must be balanced with impacts on ratepayers. But simply setting the budget and then charging the same rate to all customers can be discriminatory to some. Even if rates differ among the various rate classes, modifying rates by the same amount can also be discriminatory. Consider for example, a utility that has numerous small customers and one large, industrial customer that operates for only a short period of time each year. Assume further that the industrial customer's load is large enough to require the utility to install large equipment to deliver power to that customer's facility. A single rate for all customer classes may result in other rate classes paying for the additional infrastructure since the industrial customer operates for only limited times. Accordingly, a cost-of-service analysis is an integral part of any rate study where revenue requirements are allocated to each rate class and rates then set that will recover the required revenues. This process, described later in this report, results in rates that fair and equitable such that the "cost causer" is the "cost payer." The last rate study performed by the Seward Electric System ("SES") was completed in 2021. Since then, costs have significantly increased for a number of items, deferred maintenance has been performed, and several large capital additions have been made. Staff now believe that rates are inadequate to fund on-going operations, and a rate review is now required. The Financial Engineering Company was retained to perform this review, and this report summarizes the analysis and findings. TERMS Certain terms are used in this report that may not be familiar to those not closely associated with the power industry. These terms are described below. I. Introduction Page 2 197 Enerqu The total amount of power consumed over a given period. For example, a 100-watt light bulb, if left on continuously, uses 2,400 watt-hours of energy during a 24-hour period. During the entire year (8,760 hours), 876,000 watt-hours of energy are consumed. Units: The unit of measurement is typically kilowatt-hours (kWh) or megawatt-hours (MWh). 1 MWh = 1,000 kWh = 1,000,000 watt-hours Demand, or Peak Demand The maximum rate of consumption of power. Usually, this is measured over a 15-minute period, but instantaneous demands are also used. If in the previous example a second light is turned on for 15 minutes, then the peak demand is 200 watts. Units: The unit of measurement is typically kilowatts (kW) or megawatts (MW). 1 MW = 1,000 kW = 1,000,000 watts System Peak The combined peak demand of all utility customers placed on the utility. Units: kW, MW Coincident Peak ("CP") The usage of power of a particular rate group at the time of system peak. Units: kW, MW Non-Coincident Peak ("NCP") The peak demand of a particular rate group. The non-coincident peak of a rate group does not necessarily happen at the time of the system peak. If the rate group's non-coincident peak occurs at the time of its coincident peak, then the two are equal, otherwise (as is usually the case) the non-coincident peak is greater than the coincident peak. Units: kW, MW I. Introduction Page 3 198 Coincident peak and non-coincident peak are illustrated in the following figure.

Units: kWh, kW-months, customer-months Base Rates Rates that are set by the utility to recover the annual revenue requirements that are not associated with fuel or purchased power costs. Base rates include a customer charge, energy charge, and demand charge and are set through action by a governing body. Base rates are in effect for periods of one or more years; whereas fuel and purchased power costs are typically recovered through a separate charge that changes on a monthly or quarterly basis. I. Introduction Page 4 199 Cost of Power Adjustment ("COPA") A rate that recovers the cost of generating fuel and purchased power. SES purchases all of its power requirements from Chugach, who charges a base rate and its own COPA. SES passes these charges on to its customers at cost via the SES COPA. I. Introduction Page 5 200 II. COST-OF-SERVICE STUDIES THE PROCESS Before one can understand the process of how a cost-of-service study is performed, one must first understand the infrastructure of a utility and what are the influencing factors in developing this infrastructure. To procure and deliver power to a customer, the utility must: • Construct a generation system or procure power from some source. • Construct a transmission system to deliver the power from the generating site to the distribution system. • Construct a distribution system complete with poles, transformers, and meters to deliver the power to the end user. • Hire staff to operate and maintain the system and to perform administrative duties such as meter reading, preparing and sending out bills, and other activities. Thus, the utility's functions can be categorized as those being related to Generation/Production, Transmission, Distribution, Customer Accounts, and Administrative. But what factors influence each of these functions? The Generation system must be sized to meet total system peak (or, Coincident Peak) along with adequate reserves. The Transmission system must also be sized to meet the Coincident Peak as power is delivered from remote areas to the system. The Distribution system is, however, a bit more complex. Poles, wires, meters, and transformers are, to a large extent, a function of how many customers there are. But the size of wires and transformers are also a function of how large a customer is since a customer with a larger load requires larger equipment to carry the load. Thus, the Distribution system is sized to meet both the number of customers and size of load. Since the distribution system is not sized to meet the total system load but rather the load in the immediate area, the Non-Coincident Peak is used. Customer accounts, which includes meter reading, billing, and other related activities, are influenced by the number of customers regardless of the size of the customers' loads. Recognizing these influencing factors, the National Association of Regulatory Utility Commissioners ("NARUC") has developed and published a process for II. The Process Page 6 201 allocating utility costs to the utility's rate classes so that a utility's rates are not arbitrary or capricious toward any one or more rate classes. All Alaskan electric utilities that are rate regulated by the Regulatory Commission of Alaska ("RCA") must use the process set forth in the NARUC Manual when adjusting base rates. Although SES' rates are not regulated by the RCA, the methodologies set forth in the NARUC Manual are used herein. In very general terms, the analysis is performed in a multi-step process. These steps are: 1. Projecting the amount of customer months, energy sales, and demand sales. 2. Projecting the utility's revenue requirements. 3. Functionalizing the revenue requirements into those being related to generation, transmission, distribution, and other functions. 4. Classifying the functionalized revenue requirements into those being related to energy, demand (coincident and non-coincident), customer, or direct. 5. Allocating the classified revenue requirements to each rate class based on the contribution of each class to that classifier. 6. Designing rates that will recover each rate class' allocated cost of service. The first two steps are described later in this report, whereas the next three (Functionalization, Classification, and Allocation) are described in general terms below. FUNCTIONALIZATION A utility's production, transmission, distribution and consumer accounts expenses are functionalized through the Uniform System of Accounts. Administrative and General expenses, interest expenses, and other items are functionalized as either production, transmission, distribution, or consumer accounts using the labor components of expenses already functionalized, functionalized plant in service, and other factors. CLASSIFICATION Once the revenue requirements are functionalized, they are then classified as either demand-, energy-, or customer-related. At the risk of over-simplification, the NARUC Manual prescribes the functionalized revenue requirements to be classified as shown in Table 1. As one can see, the classification mirrors the influencing factors described on the preceding page for each function. Detailed classification methodologies for the various line-item expense codes are provided in the NARUC Manual with the goal of classifying in a fair and equitable manner. The II. The Process Page 7 202 NARUC Manual is published for the use of all utilities nationwide and acknowledges that certain deviations from the methods prescribed may be warranted due to local conditions. Table 1 SES COST OF SERVICE STUDY Classification of Revenue Requirements Functionalized Classification Revenue Demand Requirement Coincident Non Energy Customer Coincident Production x x Transmission x Distribution x x ALLOCATION The final step in the cost-of-service analysis is to allocate the classified revenue requirements to each customer class (or rate group) based on each class' respective use of the allocation. For example, energy is typically allocated based on sales. If a particular class accounted for 30 percent of the sales, then 30 percent of the costs classified as energy-related would be allocated to that class. Energy- and customer-related expenses are fairly straightforward, but demand allocations become much more complex since there are a number of different methods that can be used. Some form of the coincident and non-coincident peaks are typically used, with such forms including the annual peak, average of the four peak months, average of the twelve months over the year, average of the three summer and three winter peak months, and so on. Further complicating the matter is that a great deal of load research must be conducted in order to estimate these class peaks with any precision. Such research can be expensive, and the benefits of obtaining the data can quickly be eroded by the associated costs. Load research of comparable utilities and an analysis of billing demands can be used in lieu of the expensive load research. After the revenue requirements have been allocated to each class, the existing rates are applied to the billing determinants (number of customers, energy sales, demand sales) to determine if the rates recover less than or more than the allocated cost of service. Rates are then adjusted accordingly. It is important to understand that there are inherent inaccuracies in the process, and it is not an exact science. The goal is to set rates such that they 11. The Process Page 8 203 are reasonably close to the allocated cost of service, thereby allowing other factors to be considered. Such factors might include foregoing large rate shocks to a particular class, economic development, and others.

SES SYSTEM POWER SUPPLY COSTS SES receives all of its power supply from Chugach, although back-up generation is maintained in the event of service disruptions. The monthly CEA bill for power consists of a small customer charge, an energy charge, a demand charge, and the fuel and purchased power adjustment ("FPPA"). The first three rates are modified through a general rate proceeding with the RCA, whereas the FPPA is adjusted quarterly based on CEA's fuel costs and generating efficiencies. CEA reduces the overall bill by a fixed amount each month in recognition of SES' share of the Bradley Lake Hydroelectric Project. Chugach rates are regulated by the Regulatory Commission of Alaska ("RCA"), and the utility has recently filed for a rate increase. Presentations by Chugach indicate that the base rates (non FPPA) charged to SES will increase by approximately 16.5 percent. When the FPPA is included and assuming it does not change, the cost of power from Chugach is projected to increase by approximately 6.5 percent. The overall process with the RCA takes approximately a full year from the time of filing. RATE STRUCTURE SES has five primary rate groups and two additional sets of rates for Yard Lights and Street Lights. Rates charged to each rate class are comprised of two major components - Base Rates and COPA. Base rates are, in turn, further subdivided into three sub-components, and each is described as follows. 1. Base Rates. Implemented to recover costs of the system that are not related to fuel or purchased power. Base Rates do not fluctuate during the year and are changed only through Council action. a. Customer Charge. A fixed dollar amount the customer must pay each month regardless of how much energy is used. These rates are implemented to recover some of the fixed, customer-related costs of the utility such as carrying charges and depreciation of transformers, meters, service connections, and part of the distribution system as well as expenses related to meter reading, billing, and customer service. b. Demand Charge. A charge based on peak usage (in kilowatts, or kW) during the month. These charges are used to collect part of the demand-related costs of the system such as those associated with production, transmission, and part of the distribution III. SES System Page 11 206 plant. The demand charge is applied only to Large General Service and Industrial customers. c. Energu Charge. Used to recover the remaining revenue requirements and charged based on energy usage by the customer. 2. Cost of Power Adjustment. The COPA is implemented to recover all purchased power costs. It is assessed on all energy used by a customer. Rates in effect are summarized in Table 2.

BILLING DETERMINANTS AND REVENUE REQUIREMENTS BILLING DETERMINANTS The number of customers and energy sales for the 2012 - 2022 time period are shown in Table 3, and energy sales are summarized in Figure 3. In 2021, SES established an Industrial rate class that included three customers, one being the Alaska SeaLife Center which was at the time being served under a Special Contract. Billing data is available for each of these customers from 2020 and is separated in the table. Prior to then, the three customers are combined with the Large General Service rate class. As can be seen, total energy sales have increased from the pandemic years but are still lower than ten years ago. Billing determinants incurred during 2022 are used for this study, and these are summarized in Table 4.

Typical rate studies are based on the projection of a single year. However revenue requirements are expected to significantly increase in the next several years due to two primary factors. First, staff believes the utility is understaffed for reliable operations, and existing salaries are inadequate to attract and retain quality personnel. Therefore, current labor expenses are believed to be unrealistic and need to be adjusted upward. Second, several large capital expenditures are being planned, and such additions will increase depreciation expenses. Part of the additions is planned to be funded with debt, and interest expenses will also increase. Accordingly, the 2022/2023 budget is used as the basis for this study but with projections through and including 2026. Most budget line items are increased at the assumed inflation rate of 2.5 percent per year, but many are adjusted using specific assumptions. These assumptions are described as follows, and the projections are summarized in Table 6 at the end of this section and provided in their entirety in Appendix B-1. IV. Billing Determinants / Revenue Requirements Page 15 210 1. Labor. Preliminary estimates by staff for the combined effect of increased staffing and salaries was $835,000 per year. That estimate has since been reduced to $675,000 per year, or 61.6 percent above that budgeted for 2023. All budgeted labor and benefit amounts are increased by this percentage in 2024 and increased with inflation thereafter. 2. Contracted Services - Transmission. The 2022 and 2023 budgeted amounts are $800,000 and $500,000, respectively. This relatively high amount reflects the clearing of right-of-ways and is expected to be completed by the end of this year. The amount assumed for 2024 and thereafter is $200,000 per year plus inflation. 3. Transmission Clearing - Chugach recently informed SES that SES would now be responsible to pay for its share of clearing the transmission right-of-way between the Daves Creek and Lawing substations. Chugach's estimate of the SES share is $400,000 in 2024, and this amount is included in the revenue requirements. Clearing is expected to occur every 2 - 3 years, and an additional $300,000 plus inflation is included in 2026. 4. Wholesale Power Costs. This line item represents wholesale power purchases from Chugach. Since these costs are recovered through SES' COPA, they are eliminated from the revenues requirements. 5. Contractual Services - General Operations. The 2022 budgeted amount is $925,287 but decreases to $325,000 for 2023. On-going amounts are assumed to be $350,000 in 2024 with inflation thereafter. 6. Operating Supplies. The 2022 budget is $262,286 and decreases to $50,000 for the 2023 budget. Projections are based on the lower amount budgeted for 2023. 7. Operating Materials. The 2023 budget is $300,000 with no prior amounts (budgeted or historical). The amount is increased to $450,000 in 2024 with inflation thereafter. 8. General Fund Administrative Fee. The budgeted amount of $1,035,780 for 2023 is held constant thereafter. Conversations with City personnel did not reveal the basis for this number, and it is recommended that the City review how this is charged to its various departments. 9. Payment in Lieu of Taxes ("PILT"). This item was not included in the budget but is still assessed to the utility. Historical amounts have been in the range of $1 million, and this amount is included for 2023 and increased with inflation thereafter. Staff indicates that the assessed amount is to be levied at the rate of 8 percent of all revenues. It is noted that fuel costs are part of the Chugach bill, and the assessment could vary with Chugach's fuel costs. IV. Billing Determinants/ Revenue Requirements Page 16 211 10.Major Repair and Replacement Fund - Historically, SES (and other City departments) have made annual contributions to this fund. However, no contributions have been made over the past several years, but such contributions should be made to lessen the reliance on future debt. Preliminary analyses were based on a $500,000 annual contribution, but due to the impact on rates, the contribution has been reduced to $350,000 per year plus inflation. The amount is added to the revenue requirements for 2024 and thereafter. 11.Depreciation. Depreciation expenses are based on depreciation schedules of existing assets and assumptions regarding future capital additions (explained later). 12.Motor Pool Rent. Assumed to decrease to $100,000 per year and escalated at inflation. 13.Debt Service. Interest payments are based on actual schedules and assumptions regarding future debt. Principal payments on debt are excluded as an expense since the inclusion of depreciation on the assets funded with debt would be a double counting of expense. 14.Capital Expenditures. The assumed future capital expenditures are summarized in the following table. New debt is assumed to be a 20- year note, amortized at 5 percent. Potential capital expenditures for expanding office space required for additional staff are not included at this time.

Billing Determinants / Revenue Requirements Page 17 212 15.Target Margin. There are certain inherent inaccuracies in the projection of both revenues and revenue requirements. Actual expenses may be higher or lower than projected as might be actual billing determinants (energy sales, billing demands, etc.). It is, therefore, prudent to increase the revenue requirements by some amount to take into account these inaccuracies. This additional amount serves two other purposes as well. First, it provides the capital to fund future additions, thereby reducing debt. Second, it allows rates to remain in effect for a longer period of time as inflation increases operating expenses. Since revenue requirements include contributions for the Major Repair and Replacement Fund, the target margin has been reduced from $500,000 included in earlier drafts to $300,000. This represents approximately 2 percent of operating costs when wholesale power purchases are included. It is important to note that the revenue requirements are relatively fixed in nature. Certain costs may be influenced by the number of customers; but even then, these costs are fixed once the infrastructure is built. It is only billing-related costs that are directly influenced by the number of customers at any one time, and these costs represent a very small amount of the total revenue requirements. Thus, the revenue requirements will not be influenced by the level of energy sales or the number of customers. IV.

REVENUE ADEQUACY AND COST ALLOCATION ADEQUACY OF EXISTING RATES By applying the existing rates to the billing determinants previously shown in Table 4, revenues can be projected over the study period. These revenues, shown below in Table 7, are then compared to the projected revenue requirements. As seen in Table 7, rates should be increased immediately by $0.060/kilowatt-hour by the end of this year followed by $0.003 two years hence.

Cost Allocation and Results 20 215 To gain an insight into how these rate increases might be lessened, every $500,000 of revenue requirements equates to slightly under $0.01/kilowatt- hour. Steps that the City or SES might implement to lessen the required rate increases are discussed in the next section. COST OF SERVICE While the overall rates must be adjusted, the question then becomes how should the rates within the various rate classes be adjusted? Should they all be adjusted by the same amount, the same percentage, or a different amount for each rate class? The allocated cost of service analysis provides insight into this. But, it must be stressed that cost-of-service studies are not an exact science. Although the NARUC Manual was established to set forth guidelines in classifying the various revenue requirements, the process requires estimates of certain allocators to be made. Furthermore, customers in one rate class are "generally" in different locations than others, but geographical boundaries are typically blurred. Finally, the process is based on a snapshot in time, and usage patterns and relative usage change over time. All in all, the results should not be taken as exact numbers but rather guidance on whether rates are set too high or too low. ALLOCATION FACTORS As described in Section II of this report, demand-related expenses are allocated based on estimates of each class'contribution to the coincident peak and the non-coincident peak. For a large utility, these estimates are developed through detailed load research where the hourly usage of customer sample groups are monitored over at least a year. From this, estimates can then be made for rate classes as a whole. This load research, however, is relatively expensive, and the benefits of gaining the data are quickly eroded for small utilities such as SES. Therefore, other methods are used, such as reviewing billing demand records for large customers and using load research data from nearby utilities. For this analysis, the load research data developed by Anchorage Municipal Light& Power ("AML&,P") prior to its merger with Chugach is used as guidance and modified where deemed appropriate. It must be remembered that load research is used to estimate load patters, not actual loads. Although AML&P is much larger than the SES system, its compactness is believed to make it a better indicator of SES load patterns than other utilities such as Chugach or Homer Electric. The derivation of coincident and non-coincident peaks is V. Cost Allocation and Results 21 216 summarized in Appendix D, and the sum of the calculated monthly coincident peaks is within 1 percent of the actual amount. SCENARIO DESCRIPTIONS The cost allocation analysis was conducted using a single year of revenue requirements. A multiple year analysis would result in over-collection in some years and under-collection in others. In anticipation of selling the utility again being put before the voters, two scenarios were investigated. Scenario 1: Retention of the utility and bringing it up to date. Revenue requirements are based on those projected for 2024, the initial year of the increased labor expenses. Table 7 showed that a small increase would be required the following year. Scenario 2: Sale of the utility with no staff additions or major capital improvements. Revenue requirements are based on those projected for 2023. Since the approval process for the sale of the utility would take at least a year, inclusion of the target margin in the revenue requirements is critical to maintain adequate revenues as inflation cuts into margins during the approval process. RESULTS The results are summarized in the following tables, and details of the results are provided in the Appendix. Specific rate options are discussed in the following section. Scenario 1 - Utility Retention (Table 8): Rates must be increased by an average of $0.060/kilowatt-hour to meet revenue requirements. All rate classes must be increased with those of the Residential and Industrial being the largest increase. The $0.060 increase should be implemented in 2023. A further rate increase of approximately $0.003/kilowatt-hour would be required at the beginning of 2026 absent cost cutting measures that might be implemented (discussed in the next section). Scenario 2 - Utility Sale (Table 9): Rates must be increased by an average of$0.021/kilowatt-hour to meet revenue requirements. Again, the largest increases are found with the Residential and Industrial rate classes. Since revenue requirements are based on the 2023 budget, the increase should be implemented in 2023 even if the utility is to be sold. Since the approval process for the sale will take at least a year, a rate increase is required to maintain adequate revenues during this process. V.

Cost Allocation and Results 24 219 VI. CONSIDERATIONS AND OPTIONS Even though the path forward regarding SES rates will depend on whether the utility is sold, some form of rate increase must be implemented this year. Sale of the utility requires an average increase of $0.02 1/kilowatt-hour, whereas a $0.060/kilowatt-hour average increase is required if the utility is retained. Two overall questions must be considered by the City regarding these adjustments: 1. Should the revenue requirements be adjusted from that used in the analysis? 2. Should the rate increase be applied on an equal basis to each rate class or should the rates be moved closer to their respective allocated cost of service? REVENUE REQUIREMENTS There are a number of actions that can be implemented that would result in reduced revenue requirements. Several of these, however, are policy decisions that would impact rates of other City services. Therefore, these actions are focused more toward Scenario 1 - Utility Retention. Every $1 million reduction (or addition) in revenue requirements represents a $0.018/kilowatt-hour change in the required adjustment. PILT: The analysis is based on a PILT assessment of$1,000,000. The rate of assessment (8 percent of revenues) could be lowered. Administrative Fee: The analysis uses the budgeted amount of $1,035,780 for each year of the study period. How this was developed could not be determined, and the total amount assessed to each department and how it is assessed should be reviewed by the City. Target Margin: Originally, a $500,000 target margin was investigated; but in an attempt to lessen the impact on ratepayers, a margin of $300,000 was used for each year. Further reductions are not recommended, especially for Scenario 2 - Utility Sale. Revenue requirements for that scenario are based on the 2023 budget, and inflation will increase costs during 2024 when the sale is progressing through the approval process. Increased Costs for Utility Retention. This analysis is based on preliminary estimates of the increased expenses required for long-term safe and reliable operations. A working group was recently formed to investigate this in more detail, and revenue requirements may be more or less than that used. VI. Considerations and Options 25 220 RATES AND COST OF SERVICE The analysis showed that all rates must be increased, with Residential and Industrial being the farthest from the allocated cost of service. Should the rate adjustment be applied on an across-the-board basis (same $/kWh increase to all or same percentage to all), or should the rate adjustment to each class differ in an attempt to move them closer to cost-of-service? As noted before, cost-of-service studies are not an exact science, and striving for a zero deviation between class revenues and allocated cost of service is not warranted. Scenario 1 - Utility Retention showed both Residential and Industrial being furthest from cost of service. However, the required adjustments of 50 percent and 53 percent are quite high, and having other rate classes sharing part of it may be in order. For Scenario 2 - Utility Sale, it is recommended that the average rate adjustment of $0.02 1/kilowatt-hour be applied to all rate classes. SES will eventually be blended in with the purchasing utility's own rate classes and cost of service, and an across-the-board increase might lessen rate instability. RATE OPTIONS Scenario 1 - Utilitu Retention Several options are presented in Table 10 with the monthly increase for the average customer in each rate class shown. The average for the Boat Harbor is based on 28 meters, whereas there are numerous end-use customers for each meter. Other options certainly exist and can be explored as requested. Option 1. Increase each rate by $0.055/kilowatt-hour. This results in revenues meeting all revenue requirements but with a very small margin. This option is not recommended unless the revenue requirements can be lowered through policy changes described earlier. Option 2. An across-the-board increase of$0.059/kilowatt-hour. This increases the margin to approximately $269,000, a bit less than the target margin of $300,000. If no other cost-saving measures are implemented, this option would most likely allow rates to be held constant until 2026. Option 3. An across-the-board increase for the full $0.060/kilowatt- hour. The Residential rate class is within 92 percent of its allocated cost of service with the other rate classes making up the difference. Option 4. Implementing rates that move each class closer to cost of service while attempting to lessen the large increase required for Residential. All are within 5 percent of the allocated cost-of-service, which is considered reasonable. VI. Considerations and Options 26 221 Scenario 2- Utility Sale As previously stated, it is recommended that the full $0.02 1/kilowatt-hour increase be implemented on an across-the-board basis.

From that study, an Industrial rate class was established and the Alaska SeaLife Center was moved from its special contract to the Industrial rate.' Residential rates were also increased, but both the Residential and Industrial rates were less than their allocated cost of service. Since the time of that study, deferred maintenance items have been completed and debt has been taken on to complete several capital additions. Perhaps more important, staffing levels have been identified to be insufficient to maintain on-going reliable operations. That, coupled with the need for higher salaries to attract qualified personnel, could add nearly $1 million in increased operating costs. All of this, combined with the high general inflation that has occurred over the past two years, has created a potential shortfall in utility revenues. Accordingly, a cost-of-service study was conducted to investigate the adequacy of existing rates and how close each rate class was to its allocated cost of service. Two separate scenarios were investigated: 1. Retaining the utility and implementing measures to ensure long-term reliability. This assumed staff would be expanded, salaries increased, and capital improvements continued to be made. 2. Not implementing these measures in anticipation of selling the utility in the very near future. SCENARIO I -UTILITY RETENTION The analysis found that retaining the utility with the increased costs resulted in a revenue shortfall of $0.060/kilowatt-hour for 2024 and an additional $0.003/kilowatt-hour in 2026 (Table 7). Rates for all rate classes were less than cost-of-service, but Residential and Industrial rates required the largest increase (Table 8). Included in the revenue requirements for this scenario were a target margin of$300,000 per year and transfer to the City's General Fund of approximately $1 million each for Payment in Lieu of Taxes ("PILT") and the City ' The SeaLife Center is transitioning to the full Industrial rate over a period of time with the full rate being implemented January 2025. VII. Summary and Recommendations 28 223 Administrative Fee. The $300,000 target margin represents a reduction from that presented to the City Council on September 11, and further reductions are not recommended. The cost of increased labor costs are based on preliminary estimates and do not include capital improvements that might be necessary to accommodate the increased staffing. PILT and the Administrative Fee can also be lowered, but presumably any reduction from SES transfers would have to be made up from other sources. As point of reference, a reduction of $1 million in revenue requirements equates to approximately $0.018/kilowatt-hour. SCENARIO 2 -UTILITY SALE Although the increased labor costs and capital spending were not included in this scenario, a revenue shortfall equal to $0.021/kilowatt-hour still exists (Table 9). This increase is due to the debt and depreciation associated with the recent capital improvements and general inflation over the past two years. As with Scenario 1, all rates for all classes are currently less than cost of service with Residential and Industrial requiring the largest adjustment. Options to reduce the revenue requirements are limited for this scenario. There would be insufficient time to investigate the effect of reducing the PILT or Administrative Fee. Furthermore, a reduction in the target margin is not recommended since on-going operations and maintenance costs will increase with inflation during the approval process if the utility is sold. RECOMMENDATIONS The City's course of action regarding SES rates will depend on the decision to sell the utility. The following recommendations are made for the City's consideration. SCENARIO 1 -UTILITY RETENTION 1. Implement a rate increase averaging at least $0.059/kilowatt-hour (Options 1.2 in Table 10). This would be sufficient until 2026 when a smaller increase of $0.003/kilowatt-hour is projected to be required, dependent on any cost-saving measures that might be implemented. 2. Investigate the methodologies used in developing the PILT and Administrative Fee and how any reduction to SES would be made up. SCENARIO 2 -UTILITY SALE 1. Implement a rate increase of $0.021/kilowatt-hour on an across-the- board basis. 2. Reductions of the target margin in an attempt to lower the rate increase is not recommended for reasons stated herein. WI. Summary and Recommendations 29 224 3. Investigate how proceeds from the sale could offset the loss of SES payments of PILT and the Administrative Fee and perhaps memorialize the use of such proceeds. WT Summary and Recommendations 30 225
