Program Overview :Program Overview Motor Efficiency


Rebate Requirements :Rebate Requirements New motors from 1-200 horsepower No rewound or repaired motors Must meet or exceed National Electrical Manufacturers Association (NEMA) Premium® motor efficiency standards ODP or TEFC motors


Motor Rebate Levels :Motor Rebate Levels Each horsepower has prescribed rebate amount Note: Motors & VFDs > 200 HP must be submitted through the Custom Efficiency program and receive preapproval prior to purchase and/or installation


Motor Rebate Levels :Motor Rebate Levels


Motor Rebate Levels :Motor Rebate Levels


Variable Frequency Drive (VFD) Rebate Requirements :Variable Frequency Drive (VFD) Rebate Requirements New VFDs only Prescriptive rebates for 1-200 horsepower At least 4,000 hrs. per year Two or more operating points < 55% loaded, 75% of the time Automated control system True PF ≥ .90 Flat rebate of $30/HP


VFD Rebates – Qualifying Equipment :VFD Rebates – Qualifying Equipment VFDs included HVAC fans Pumps Cooling towers Process equipment Industrial fans VFDs not included Chillers Refrigeration compressors Air compressors Non-included VFDs may qualify for Custom Efficiency rebates


Cooling Efficiency :Cooling Efficiency Rebates for purchasing and installing energy-efficient air conditioning equipment Available for small equipment up to very large equipment Two level incentive Base incentive Bonus incentive New or existing facilities


Qualifying Technologies :Qualifying Technologies PTACs Water Source Heat Pumps Condensing Units Rooftop Units Split Systems Variable Air Volume Boxes Oversized Cooling Towers Chillers


Prescriptive Program Application Process :Prescriptive Program Application Process PTACs Base: $50/ton, Bonus:$4/incremental 0.1 EER Water Source Heat Pumps Base: $50/ton, Bonus:$4/incremental 0.1 EER Rooftop Units Base: $50/ton, Bonus:$4/incremental 0.1 EER Condensing Units Base: $25/ton, Bonus:$4/incremental 0.1 EER Split Systems Base: $25/ton, Bonus:$3/incremental 0.1 SEER


Prescriptive Program Application Process :Prescriptive Program Application Process Chillers-Scroll or Rotary Screw Base: $10/ton, Bonus:$3/incremental 0.01 kW/ton Chillers-Centrifugal Base: $12/ton, Bonus:$3/incremental 0.01 kW/ton VAV Boxes $200/Box, must replace a CAV system Cooling Towers $3/nominal tower ton


Sample Rebate Calculations :Sample Rebate Calculations Rooftop AC example Assume 10 ton rooftop unit, 12 EER Minimum Efficiency is 11 EER Base rebate $50/ton $4/ton for each increment above base 10 ton x $50/ton = $500 (12 EER-11 EER)/0.1=10 10 ton x 10 x $4/ton = $400 Total: $500 + $400 = $900


Prescriptive Program Application Process :Prescriptive Program Application Process Determine if equipment qualifies Purchase and install equipment Complete rebate application Customer must sign application Submit application with invoice to Xcel Energy Date and place of purchase Nameplate nominal efficiency Manufacturer and model or part number Labor Costs to install Rebate check sent to customer in 6-8 weeks


Program Overview :Program Overview Custom Efficiency


Custom Efficiency :Custom Efficiency Incentives for customers to encourage them to implement energy-saving projects or process changes that are not covered by the prescriptive programs Xcel Energy pre-approval required prior to equipment purchase


Custom Efficiency Requirements :Custom Efficiency Requirements Pre-approval required prior to purchase Simple paybacks between 1-15 years Rebate amount offered valid for 1 year from pre-approval date Rebates cannot exceed 50% of the project cost Rebates apply to new equipment Leased equipment may qualify Used equipment does not qualify


Program Overview :Program Overview Energy Design Assistance


Energy Design Assistance Overview :Energy Design Assistance Overview We work with commercial building owners, architects and engineers Evaluate potential energy-efficiency improvements For new construction, major renovations or additions Start when designing plans


Requirements :Requirements >50,000 sq. ft. for commercial facilities >150,000 sq. ft. for housing Early enough to influence decision-making Schematic design or design development Stages


Features :Features Free energy modeling and verification Owner incentives for implementation Payment to architectural and engineering team


Recommissioning Program :Recommissioning Program Building Tune-up Program Offer incentives for energy study Study evaluated the HVAC and energy management system Offer incentives for implementing measures Buildings must be 50,000 sq. ft. or greater


Compressed Air Program :Compressed Air Program Dependant on compressor size - Xcel Energy funds study costs as follows: 50 - 99hp - Xcel Energy pays 100% of study cost up to $2,500 100+ hp - Xcel Energy pays 75% of study cost up to $15,000 Reimbursed within 6 weeks after study is completed, reviewed and 50% of air loss repaired Equipment rebate is through Custom Efficiency Program
