WHY THIS MATTER IS BEFORE THE BOARD This workshop item is before the Board to provide a year-end review of the FY11 Conservation Department programs and to present a projected plan for the FY12 Conservation Department programs. 2. HISTORY The District has been investing in new conservation programs and capacity while continuing to deliver our robust stable of energy and water saving programs. The current conservation energy and water programs can be found on our website at vwvw.tdpud.org. As verified and reported through our Evaluation, Measurement, & Verification (EM&V) efforts, the District has a successful track record of very cost- effective programs. The District has expanded beyond traditional rebate programs and now also offers give-a-way and direct-install programs. The primary goal of the District's conservation programs remain to maximize return on equity for our customers and to ensure that all of our customer segments have the opportunity to participate in our programs. Staff has been working to deliver, and optimize, existing programs and to develop and bring to our customers new water and energy savings programs. 3. NEW INFORMATION FY11 performance of the Conservation Department programs was on budget and met expectations. The independent, outside EM&V work is largely completed and the results for the 2011 energy conservation programs are very impressive: Net annual savings of 3,400,293 kWh, Net lifecycle savings of 30,824,481 kWh, and a TRC of 2.81 (see Attachment 1). These results will again put the District in the top of California utilities for both energy savings and cost-effectiveness. To put these numbers in perspective, the District's 2011 energy conservation programs resulted in a first-year energy savings of over 2.2% of gross electric sales at a fully loaded cost of around $0.031/kWh. The benefits include cost savings to the District and money in our customer's pockets. The 2011 results are slightly down from previous year's reflecting the 'diminishing returns nature of energy and water conservation. The impact of the program in 2011 (over 2.2% first year savings, around $0.031/kwh loaded cost) remain very strong, but were impacted by the following factors: change in the E3 model's avoided cost assumption (this lowered TRC for all utilities); the inclusion of water programs in this year's EM&V (helped electrical savings but hurt overall electrical cost-effectiveness); and the continued decline in the number of CFL 12-packs that we hand out as we continue to saturate this measure (13W CFL's have dominated both our energy savings and cost-effectiveness in the past). Charts showing first-year kWh savings and cost-effectiveness (TRC)for the last four years are attached (see Attachment 2). In terms of specific 2011 energy conservation program results (2010 #'s for comparison,): • Commercial Rebates: 26 (38); • Residential Rebates: 676 (768}; • Energy Savings Program Customers Served: 85 • Residential Energy Survey Customers Served: 279 (48); • Holiday Light Exchange Customers Served: 700 (684}; • Residential Green Partners Customers Served: 689 • Business Green Partners Customers Served: 80 (59); • Keep Your Cool Customers Served: 10 (36); and • Screw-in CFL's Distributed: --51,000 (--60,000) In terms of new program development for energy conservation in 2011, the Green Schools Program/Trashion Show effort remains extremely popular with the District distributing 1,800 conservation kits to every elementary and middle school student in our territory. The educational component and the visibility within the community of this new program were even more impressive. The next round of Neighborhood Resource Mobilization 'block parties' was also very successful with solid events in the Prosser Lakeview and greater Sierra Meadows neighborhoods. The Residential Energy Savings (RES) Program expanded dramatically and customer response remains very positive. Staff continues to hand out free compact fluorescent light bulbs (CFL's) and, as we have started to saturate the 12-pack spiral market, staff is moving towards other types of CFL's. New LED lighting programs are beginning to take shape but the technology is still developing across all applications. In terms of specific 2011 water conservation program results (2010 #'s for comparison): • Toilet Rebate Customers: 149 customers, over 370 toilets (165 customers, over 270 toilets); • Toilet Exchange Customers: 236 customers, over 420 toilets (12 customers, over 15 toilets); • Customer Leak Repair Rebates: 90 (42); • Combined ESPIRES Customers Served: 364 • Low-Flow Showerhead Distributed: --2,250 (--3,350); • Low-Flow Sink Aerators Distributed: ~2,800 (--4,000); and • Low-Flow Hose Spray Nozzels Distributed: --4,200 (0) In terms of new program development for water conservation in 2011, the District introduced TDPUD Water Day which included an on-site toilet exchange, conservation garden tours, and other water savings measures and information. Staff continued to promote the conservation garden, including the interpretive signage and web-based resource, with the Lake of the Sky Garden Tour and other events. The Customer Water Leak Repair Rebate program is on-going and customer response has picked up. Staff expanded dramatically the new Water Efficient Toilet Rebate Program and . . + v the new toilet exchange program towards with strong customer participation. The commercial Smart Water Controller Program, that was started in FY09, is on-going and staff is reviewing the water-savings data to determine if the program should be continued. Over 1,800 low-flow hose spray nozzles were distributed to school kids through the 'Trashion Shows'. The proposed FY12 Conservation programs along with a break-out of funding and projected activity levels is included as Attachment 3. The District currently has a very comprehensive stable of programs and Staff will continue to implement and optimize the existing programs. Potential changes to existing energy programs include responding to the work at the Federal level to ban the sale of incandescent screw-in light bulbs (starting with 100W incandescents in 2012) and the ban in July of 2010 on the manufacture of T12 fluorescent tubes and magnetic ballasts for wired-in lighting. Staff is proposing phasing out commercial lighting rebates for T12's by June 30, 2012 with a 'last- chance' blitz to try and incent customers to upgrade to more efficiency lighting. New energy program development is proposed to focus on improving our appliance rebate program by lowering the Energy Star rebate to $50-75 and increasing the rebate for more efficient models (CEE Tiers 1-3 to $1004150) and introducing a residential rebate for screw-in LED light bulbs ($5/bulb). The District will continue to track the efficiency work on plug-in electronics (TV's, computers, games, etc.) along with optimizing our efforts on ESP and RES. Based on solid results, it is anticipated that the neighborhood block party concept will continue. New water conservation program development is proposed to include an incremental incentive to purchase 1.28 gpf or dual-flush high-efficiency toilets ($25 additional over standard $100 rebate/exchange) and an incremental incentive to purchase high- efficiency clothes washers ($25-$50 water rebate for CEE Tiers 2-3 over applicable energy rebate). The District will continue to develop and promote the Patricia S. Sutton Conservation Garden and web-based resource along with the Customer Leak Repair Rebate voaram. 4. FISCAL IMPACT The FY12 budget includes funding for the District's energy and water conservation programs. There is no direct fiscal impact associated with this workshop item. 5.
