2. Northwest Power and Conservation Council slide 2 Todays Discussion Approach Approach Measure List Measure List Results Results Specifications Specifications Recommendation Recommendation

3. Northwest Power and Conservation Council slide 3 Approach Fixture-for-fixture retrofit, similar light output Fixture-for-fixture retrofit, similar light output –Plus or minus 20% mean lumen system output One or two measures per base system One or two measures per base system –Based on BPA ESO list of recommended retrofits –With Additions & Deletions Fifth Plan Estimates Fifth Plan Estimates –Hours of operation by business type –Interaction estimates by business type & space heat fuel –Weighted average A/C penetration

4. Northwest Power and Conservation Council slide 4 Approach Costs include lamps, ballasts, labor, and fixture costs if applicable Costs include lamps, ballasts, labor, and fixture costs if applicable Cost & savings include on-going periodic replacement costs or savings Cost & savings include on-going periodic replacement costs or savings –Replacing lamps & ballasts –Cost can be positive or negative depending on pre- and post- equipment life, cost, labor, number of lamps Many applications have significant space heat interaction Many applications have significant space heat interaction

5. Northwest Power and Conservation Council slide 5 Measure List Started with BPA list of existing systems with suggested retrofit Started with BPA list of existing systems with suggested retrofit Culled 24 measures: Culled 24 measures: –Exit signs (they are in a different deemed list) –Retrofits with less than 80% mean light output –Measures where costs could not be obtained Added 24 measures: Added 24 measures: –Standard T8 to High Performance T8 options –High Output Options: »6-lamp HP T8, 6-lamp and 8-lamp T5 HO –20W ceramic metal halide Plan: Cull another 10 measures for post-2006 Plan: Cull another 10 measures for post-2006 –Eliminate standard T8 as a retrofit

7. Northwest Power and Conservation Council slide 7 Nomenclature: T12 4' Fluorescent, 3-F40T12ES 34W, 1-Mag EE Size and TypeLamp DetailsBallast Details Four Foot T12 Fluorescent System with 3 lamps. Lamps are F40T12 Energy Savers at 34 watts per lamp. One magnetic ballast drives the system. Ballast complies with EPACT 92 standards.

10. Northwest Power and Conservation Council slide 10 Results 6375 Deemed Savings Values 6375 Deemed Savings Values 93% of measures (9/125) have at least one cost- effective application, those that dont are close 93% of measures (9/125) have at least one cost- effective application, those that dont are close 76% of applications (4827/6375) are cost-effective 76% of applications (4827/6375) are cost-effective Measures frequently NOT cost-effective: Measures frequently NOT cost-effective: –Expensive measures like ceramic metal halide –Some Standard T8 to HPT8 retrofits w/o delamping –Some 8 foot T12 retrofits Applications frequently NOT cost-effective Applications frequently NOT cost-effective –School applications due to low hours –Electric space heat
