Proposed Deemed Savings Values for Residential Refrigerator Recycling Programs June 7, 2005
Program Summary • Program Energy Goal – Early retirement of existing inefficient refrigerators • Secondary “Non-Energy” goals • Removal of “second” refrigerators from stock • Recycling of refrigerants, metals and other materials (PCBs)
There’s Lot’s of PotentialSales Weighted Average Residential Refrigerator Energy Use
Energy Savings Issues • Removal of units that were already going to be “decommissioned” • Removal of non-functioning units • Removal of units that were only used “part-time” • Replacement of “decommissioned” units with other “used” units • Interaction with space conditioning
Prior Program Experience:Net Savings and Remaining Life • Net savings after adjustments for “free-ridership,” replacements, partial use, etc => • California • 2002 Evaluation- 53% - 57% • 2003 Evaluation- 35% • Colorado • 61% • Snoh PUD Pilot • 62% of gross savings • Remaining Equipment Life – 6 to 8 yrs
Prior Program Experience – Gross Savings • California • 1996 = 2130 kWh/yr • 2002 = 1915 kWh/yr • 2003 = 2128 kWh/yr • Snoh PUD – 1324 kWh/yr
Proposed Inputs to Deemed Savings Analysis • Average Unit Age = 24 yrs (base year = 2001) • Average Unit Consumption = 1453 kWh/yr • Remaining Unit Life = 6 years • Average Cost for Recycling = $140
Net-to-Gross Adjustment • Net-to-Gross Adjustments • Unit would have been kept but not used - 6% • Unit would have been retired w/o program – 7% • Unit was only used Part-Time – 10% • Unit will be replaced w/another used unit – 11% • Space Conditioning Interaction • Inside conditioned space – 14% • Outside conditioned space – 0% • Overall Adjustment • Units not replace – 70% (40% of units) • Units replaced New Energy Star – 68% (60% of units)
Proposed Deemed Value Input Assumptions • Gross Savings – 1453 kWh/yr • Net-to-Gross – 69% • Net Site Savings (All units) – 829 kWh/yr • Remaining Measure Life – 6 years • Average Unit Cost (Including utility administrative cost) - $140/unit • Units Replaced – 60% • Units not Replaced – 40%
Proposed Deemed Values • Net Site Savings (All units) – 829 kWh/yr • Levelized Cost – 3.1 cents/kWh • B/C ratio (TRC) – 1.3 • C&RD credit - $110.81* *80% of bulk system value, PV to Utility System is $278 of which $140 is local distribution system value
