Regional Technical Forum Future Funding Discussion March 19, 2014 RTF PAC Presentation

Topics for Today Review funding projections spreadsheet Frequency of building stock assessments End-use load research update

Funding Projections Add 1 FTE for research design Update UES for appliance standards

Net Change ( )

Stock Assessment Frequency Assessments/Surveys needed sooner than 5 years – Lighting (due to Solid State Lighting influx) – Equipment within buildings (IT, Entertainment, wood heat, appliance density & size, DHP, …) – New Construction Residential – Behavioral aspects – New Construction Commercial – IT Sector Longer Update Cycles may be OK for: – Envelope, HVAC, Systems Integral to Buildings

RBSA Data Used Recently at RTF and in BPA/Utility Programs Roughly 80% of RTF Res. measures reference RBSA Lighting socket count, type, wattage, hours & storage Residential building characteristics & billing data for simulation model calibration Cycles per year data for Dishwashers, Washers, Dryers – (Some data used in federal standards too) Wood heat & supplemental fuel saturation Ductless Heat Pump Capacity value of EE Power Plan Development More to come from end-use metering analysis

End-Use study updates BPA offering to fund $250k of the expected $500k to keep RBSA metering project alive – Contingent upon region picking up remainder of cost RTF uses RBSA data extensively in analysis – End-use metering helpful in understanding Shape of load & savings TRC calculation Peak contribution

We Know That Residential Water Heating Load Profiles Have Changed System Winter Peak Hours

We Now Know That Using Old (ELCAP) Load Profiles Understate the Capacity Impact of Changes in Water Heater Efficiency – ELCAP Load Shape 2012 – RBSA Load Shape Annual Use (kWh) 4,700 3,000 Savings/Unit (kWh) 1,700 Water heater stock <55g 2,701,000 3,489,700 Water heater stock >55g 300, ,800 Water heater stock - Total 3,001,200 3,827,500 Annual Load (aMW) 1,610 1,311 PNW 2012 Savings (aMW) 300 Coincident Peak Load (MW) 2,940 2,370 2,035 Coincident Peak Savings (MW)
