City of Port Angeles Joint Council /Utility Advisory Committee 2013 Electric Utility Strategic Planning Session Friday, June 21, 2013 City Council Chambers 9:00 AM -3:00 PM 2013 Electric Utility Strategic Planning Session For City Council and Utility Advisory Committee Members June 21, 2013, 9AM -3PM, Council Chambers, Lunch Provided The Bonneville Power Administration (BPA) began using the "Tiered Rate Methodology" on October 1, 2011. For all parties, this was more than a change in the cost of the City's wholesale power supply; it was a fundamental change in how the BPA accounts for revenue risk with its utility customers. In 2009 and 2011, the City began a strategic process to avoid using more expensive "Tier 2" wholesale power by encouraging greater levels of energy conservation. The City is meeting its objective, and any requirements for Tier 2 wholesale power will not likely happen until after 2019. The purpose of this 2013 workshop is to consider the key issues facing the City's Electric Utility over the next two years by completing a SWOT analysis. SWOT analysis is a structured planning method used to evaluate the Strengths, Weaknesses, Opportunities, and Threats involved in a project or in a business venture. It will involve specifying the Electric Utility's near -term key objectives and identify the internal and external factors that are favorable and unfavorable to achieving those objectives. This analysis must be made to continue to ensure a reliable and low -cost wholesale power supply.

Kelly Tarp, Kevin Smit SUBJECT: Understanding DR Benefits Draft Results The objective of this project is to help clarify both to the City and its customers the potential benefits of the demand response projects currently underway (or under study) in the City, and to understand the possible impacts of city -wide installation of heat pump water heaters and ductless heat pumps. The primary goals involved in assisting the City are to: Quantify the City's hourly loads and power supply expenses Illustrate the time and dollar value of potential peak savings to the City Develop an assessment of the impact of city -wide installation of heat pump water heaters and ductless heat pumps Develop a method to quantify the potential peak savings for selected individual customers and illustrate their contribution to the City's peak Conservation Potential Update for Specific Residential Programs A high level assessment of the impact of installing ductless heat pumps and heat pump water heaters in all applicable homes city -wide was conducted. EES used some of the assumptions from the City's conservation potential assessment performed in 2009 to quantify this impact. Current savings estimates from the RTF were used for the equipment savings. Tables 1 -4 summarize the assumptions and results of this estimate. 570 Kirkland Way, Suite 100 Kirkland, Washington 98033 Telephone: 425 889 -2700 Facsimile. 425 889 -2725 A registered professional engineering corporation with offices in Kirkland, WA and Portland, OR Page 2 of 9 Table 1:General Data °wand Assumptions Residential Customers (2013) Residential Building Growth Rate Population Residential Customers (2032) 8,900 1 3% 18,500 10,723 Tablet Residential Characteristics Type Single Family Multi Family: 4 units or less Multi Family. more than 4 units Mobile Homes Single Family Basement Type Crawlspace 1/2 Basement Full Basement Vintage Pre -1980 1980 1990 Post 1992 74% 0% 23% 3% 55% 15% 25% 74% 15% 11% Heat Fuel Type Natural Gas Homes Electric Homes Other Fuel Homes Electric Heat System Type Forced Air Furnace Heat Pump Zonal (Baseboard) Other Water Heating Electric Natural Gas Clothes Dryers Electric Natural Gas Table 3V-Measure Data Savings (kWh /yr) Heat Pump Water Heater Ductless Heat Purr'. 1,62717 3,816.00 1,234 56 3,407 11 0% 88% 12% 30% 11% 56% 3% 100% 0% 100% 0% Baseboard Heated Forced -Air Electric Electric Water- Heated Total Table 4 Savings Estimates for Full HPWH and DHmplementati Numberof Annual Savings Hom!° ss t Per Home ,s- 4,366 2,339 8,900 3,816 3,816 1,627 Savings (kWh Savings per year) (aMW) 16, 660, 595 8,925,319 14,481,818 40,067,732 1 90 1 02 1 65 4 57 nit Peak Savings (kW)' 2.78 2 78 0.65 This high -level analysis shows that an overall 4.57 aMW of energy efficiency savings can be achieved through this city -wide adoption of heat pump water heaters and ductless heat pumps. In addition, this application has more significant impact in the heating dominated months, as shown in Figure 1.

This is enough to power over 2600 new homes (assuming 15,000 kWh per home). Another estimate of conservation potential that assumes in the near term 4,000 DHP's and 2,000 HPHW's can be installed, in addition to some commercial and residential lighting. The distribution CHWM is 33.423 aMW, which is the balance after taking Industrial Transmission customer's CHWM from the total amount allocated to the City.

In addition the monthly customer system peak (CSP) and the sum of the City's average heavy load hour energy (aHLH) and contract demand quantity (CDQ) are shown. As noted in February, the difference between the CSP and the sum of the aHLH and CDQ is the demand billing determinant on the BPA power bill. The resulting demand charge is shown. Based on this chart, in the month of February there were just two occasions that the City's demand exceeded the sum of the aHLH and CDQ. If the City was able to target those periods, a reduction of nearly $55,000 could be achieved in the single month. Figure 4 shows February in more detail. In 2012, the City's demand exceeded the sum of the aHLH and CDQ a total of 25 hours or 0.28 percent of the year.
