Matzke 1 c '/t- SUBJECT: Recommendation to Increase 15,000 kWh Demand Rate Threshold On December 10, 1991 the Town Board approved an ordinance requiring existing Light and Power Department residential customers on the Residential Rate using electric heat and having annual consumptions exceeding 15,000 kWh to transfer to the Residential Demand Rate by 1/1/94. The same ordinance requires residential customers on the General Service Small rate using over 15,000 kWh annually to transfer to the Residential Demand Rate by 1/1/93. At the December 10th public hearing, the Light and Power Department committed to study to possibility of raising the 15,000 kWh threshold. The Light and Power Department recommends that we change the 15,000 kWh threshold to 20,000 kWh for the following reasons: 1. Number of Customers Impacted. As the rate is written, approximately 575 customers would be required to transfer to the demand rate. If the threshold were raised to 20,000 kWh, only 325 customers would be affected. Our original intention was to transfer approximately 350 customers. 2. Average consumption in Rate Class. In 1991, customers on the Residential Rate averaged 6193 kWh annual consumption and customers on the Residential Demand Rate averaged 20,500 kWh annual consumption. After these 350 electric heat customers transfer to the Residential Demand Rate, average annual consumption on the Residential Rate will drop to approximately 5200 kWh and consumption on the Residential Demand Rate will rise to approximately 21,400 kWh. 3. Economic Impact on Customers Transferred to Demand Rate. After performing some 75 rate comparisons, we have determined that 15,000 kWh annual consumption is the break-even point between the residential and residential demand rate for customers with demand controllers. The 1-1 1' 2 2 average savings for customers with annual consumptions of 20,000 kWh is $150. (See attached graph.) This would provide a payback period of slightly less than 5.5 years for a controller with an installed cost of $800. These proposed changes do not change the intent of 1991 rate study recommendations. The changes are based on more complete information which has been developed since the December 10, 1991 rate hearing. Raising the threshold to 20,000 kWh will make the Residential Demand Rate applicable to customers who will benefit the most as well as focus on those who have the greatest impact on our system peak. The Light and Power Department requests approval to proceed with implementing this change as outlined on the attached memorandum. REM 1-2 , TOU/N OF ESTES PARK March 24, 1992 OFFICE MEMORANDUM TO: Light and Power Committee FROM: Richard E. Matzke 72 2,7- SUBJECT: Proposed Schedule for Changing 15,000 kWH Electric Rate Threshold Following are proposed milestones and dates for increasing the 15,000 kWh threshold to 20,000 kWh in the Town's electric rates: 4/9/92 Present justification for changes at regular meeting of the Light and Power Committee. 4/14/92 Town Board set public hearing for consideration of electric rate changes (threshold only) at regular Town Board Meeting on May 26, 1992. 4/24/92 Publish notice of public hearing with proposed rate changes and mail notification of public hearing and rate changes to residential customers affected by these changes. 5/26/92 Public hearing to present proposed changes to electric rates. Consider ordinance to implement changing 15,000 kWh threshold to 20,000 kwh as described in the Residential and General Service Small Rate Schedules. 6/26/92 Changes to rate schedules take effect. I do not anticipate needing the services of a rate consultant, but we will need some legal help from the Town Attorney.

REM 2-2 TOWN OF ESTES PARK April 7, 1992 OFFICE MEMORANDUM TO: Light and Power Committee FROM: Richard E. Matzke SUBJECT: Voluntary Residential Rate , Demand Control Rebate As a result of the changes to our residential electric rates effective January 1, 1992, electric heat customers on the residential demand rate with annual consumption under 15,000 kWh will have the opportunity to transfer to the residential rate. Some of these customers have demand controllers in their homes. Some of our existing residential rate customers also have demand controllers. These customers will no longer have an incentive to control their demand since their electric bills will be based on consumption only. The Light and Power Department is proposing to Offer a voluntary rebate program to these customers who are willing to control their demands during the winter months. The rebates are determined by calculating monthly bills on the residential rate for several ranges of kWh consumption and comparing these bills with estimated monthly bills on the Residential Demand Rate for the same ranges of consumption, assuming the customers control their demand. The rebate never exceeds the difference between these bills. The attached table indicates these calculations. The last column shows estimated savings to the Department on our wholesale purchased power cost. Customers who wish to participate in this program would need to apply in our office. A demand meter would be installed in the home, which would be read by our meter readers during the winter months. The rebate program would be in effect for the months of December, January, and February. Participating customers would continue to be billed on the Residential Rate and the rebate would appear as a credit on the bill. If the customer's demand does not exceed the demand shown on the following table for the appropriate level of monthly consumption, the customer would qualify for the rebate for that month. If the demand is exceeded, no rebate would apply. 2-1 M OAN-CO $ D! 4- 0 C) C) CD (D W f 06 00 co M m ui e 4- 1.0 (DI~ AC) 10100,-M O (NI LO Lf) CO N 4 r. ...LO N M 91- O 00 OLOT-MNN r- CD N LO OCD cio Cocic, 00 •- M LO CO O O C) 00 (D N 1~ (9 Z tooK©6060 LU 0 b to o to O 10 0 M 4- 4- 1.0 10 0 UJ 00010010 r-Ne*(DI~ LU !1:1 D 2 00 0 00 1~ 50 5 4 6 6 M5iOOLOOLf)9 LU C)-h O -NN R 61£61<1<06062 W (991»LO OLOLO LU Z ocioui >0 c) m c) 8 32troo0000 •-(NIN 0 5•-5>000000 >LOOLOOLOLO g :,i- -0 0 2 - N N m (9 4- f O MN ACDOO oN 0 466 10 Lo O tO N AMN N CO Ia- 000000 23 28@82@ 0 - N (N m (9 4- O $ 6 2-3 NTHLY ASSUMED ASSUMED RESIDENT TARGET TARGET REVISED DIFFERENCE DIFFERENCE FACTOR (NO CONTROL) COST COST W/CONTROL W/CONTROL COST REV DEMAND WHOLESALE 3/Lit LOAD DEMAND RESIDENTIAL DEMAND RESIDENT& 20 100.52 119.92 11.42 22.5 133.02 148.24 RESIDENTIAL RATE DEMAND REBATE 165.53 173. 9 RTREBATE.XLS MEMORANDUM TO: Light & Power Committee FROM: Monte L.

Estes Park is a typical example of this problem. The attachment to this memo shows a history of Light & Power revenue, expenses, transfers, and other information from 1979 to 1992. As the attachment indicates, total revenue increased from $2,516,188 in 1979 to $5,697,115 in 1991, an increase of 226%. General Fund transfers during this same period increased from $155,518 to $483,155, an increase of 311%. The transfer has increased 10% a year since 1984. As a percent of gross revenue, the transfer was 5.4% in 1983, 8.5% in 1991, and projected to be 9% in 1992. The increasing size of this transfer has concerned staff and elected officials of the Town for several years. As a result of this concern, staff was directed to research general fund practices among other utilities, analyze the effects of a transfer policy on our own utility, and recommend some type of transfer policy for utilization. This memo is the first step in the process. It is generally accepted in the public electric industry that it is appropriate to transfer a portion of utility revenues to the municipal general fund. one reason is that the general fund transfer is viewed as comparable to the franchise fee that would be imposed on a private utility for the right to serve citizens within the city limits. Others argue that the general fund transfer provides an in-lieu-of-tax payment as a substitute for property and 4b-1 + 11 1 , , - ,,! ··'· i "1') c )illl.R h,ivii ul I'·.1~", 1,.tiL 1,·lf.'. 1,·~11,1 '' f,11)1;1(1(1 5,1)~iii Light & Power Committee - April 3, 1992 - Page 2 other taxes that would have been collected from the private entity. Most agree that owners of a utility are entitled to a fair and reasonable return on their investment. Since the owners of the municipal utility are the citizens of the Town, the transfer is seen as a dividend to the municipal owners, as a result of taking the risk to purchase the utility in the first place, and to manage it efficiently over the years. Obviously, however, there must be a limit to what can be transferred to the general fund without damaging the economic vitality of the utility. Is there a "magic formula" that can be used to automatically set the correct amount to be transferred each year? Studies indicate there is no single formula or amount of transfer applicable to all utilities. A recent study of 41 Texas cities exhibited transfers ranging from 3% to 33% of revenues, with the average being about 12.3%. These differences reflect the fact that each city or utility is a component part of unique economic, political, and market conditions. There is general agreement; however, the worst policy of all is to have no policy. A utility needs to know what the transfer will be each year to accomplish adequate financial planning. No policY for general fund transfers leaves the utility exposed each year to the uncertainties of the public budgeting process. In many cases, utilities without general fund transfer policies have found their bond ratings downgraded as a reflection of the financial market's concern about this issue. The literature makes clear that an established transfer policy benefits a utility in the long run, since it allows better budgeting and capital planning by producing predictable conditions. The policy should be fixed, but not rigid. If the fixed policy is not set unreasonably high and is not so rigid as to be damaging to the utility, the dollar amount of the transfer can be relatively unimportant. As an example, one very large public utility has a policy allowing a transfer of 14% of gross revenue. In 1990, this amounted to 38% of the general fund revenue; however, the utility remains financially strong and supports a 'AA' bond rating. Transfer practices often reflect the philosophy behind the city's ownership of the utility. Cities which consider profit an important reason for owning a utility will typically base their transfer on a percentage of revenues or net income. Cities which operate their utility similar to a private business will often require the utility to pay some form of tax equivalent, based on assets or property value. Whatever the formula, it must meet the needs and desires of both the giver and receiver of the transfers without leaving either party unduly exposed, or in an inflexible position. 4b-2 I f)Wit 1)1 141('h l';111: 1 *1(,9 1';111:, C oloii,clo 80.417 Light & Power Committee - April 3, 1992 - Page 3 Staff is presently analyzing data from other Colorado utilities to compare transfer practices. A future memo will examine this data in detail. Staff is also gathering revenue and expense data for the last five years and preparing a 5-year Capital Improvements Plan. A Financial Plan for the Light & Power Department covering the next five years will then be prepared. This plan will project cash flow requirements based on projected revenue and expenses. A computer spreadsheet will be used to allow different financial scenarios to be tried. Staff's goal is to present this financial plan to the Light and Power Committee for possible adoption of a transfer policy prior to the beginning of 1993 budget preparation. / dh Attachment 4b-3 ; 32 32 32 39 22 32 tOiCOM 00 Clt.OrO 00 4 0 4 4 do 32 39 32 0 32 32 32 32 32 32 0 0 32 32 00 - 00 10 M CO h h (9 00 0 01 00 CO 9- 0 4 If) 4 1- C) Lr) CO 0 (9 C) 4 C) d N h Lo US US Lr; cd <C~ CO h h 06 06 LO CO N ¢9 - 1- r- CO O 00 (01 0 0 tO 00 (9 N m C) rl- (9 CO tO C) (9 ~ -OO O 1.0 1.0 * O 1.0 0) t-- 1 ~ I *........ 00 d 4 1<- 0 - co oi co in co r- 00 N NO-ON Ll (9 -0-)00 60 LOU) C)CD•-1.01~COLOC)(90)040(9 ..........

INTRODUCTION ... This overview document presents the methodologies and assumptions used in analyzing the various the demand-side management (DSM) programs selected by the Cities. DSManager is the economic analysis tool being used tocalculate the cost-effectiveness of the DSM programs on Platte River and the four Cities. DSManager produces quantitative estimates of the costs and benefits for various perspectives using the methodology defined in the Standard Practice Manual for Economic Analysis of Demand-Side Management Programs (published by the California Public Utilities Commission and the California Energy Commission in 1987). DSManager has four major categories of inputs: system data, rates data, end-use/technology data, and program data. The methodologies and assumptions are presented for each of these modules. The inputs developed from the methodologies and assumptions for each category are tailored to each individual City and their programs as necessary. The DSM· programs selected by the Cities'are listed below for reference. CITIES' PROGRAMS ESTES PARK 1. Commercial/Industrial Lighting 2. Residential Lighting 3. Residential Water Heating Cycling 4.

Matzke->ry-11«- SUBJECT: Platte River Rate Increase Purchase Power Rider Calculation Platte River Power Authority raised its wholesale power rates to member cities 5.94% effective April 1, 1992. This increase was originally to have taken effect January 1, 1992, but was delayed at the December 6, 1991 Platte River Board Meeting. The Purchase Power Rider formula adopted by the Town Board in December 1991, allows the Town to pass through this increase by calculating our purchase power costs at the new wholesale rate for the most recent twelve months, subtracting our actual purchase power costs for the most recent twelve months, and dividing by our total kWh sales for the most recent twelve months. This calculation results in a Purchase Power Rider of $0.00234 per kWh which will be added to the energy charge for all electric rates. This is an average increase of 3.56% for all rates and a 3.3% increase for the average residential customer. The Purchase Power Rider will be applied to electric bills beginning with the first billing cycle in May. REM 4e-1
