BPA Residential LED CommitteePurpose:

• Divide and conquer research tasks, contribute to collection of data for UES, collaborate on program design

Subcommittee Representation:• Program, planning and engineering staff representing:

Bonneville Power, Puget Sound Energy, Seattle City Light, Snohomish PUD, Tacoma Power, Energy Trust of Oregon, Fluid Market Strategies, Applied Proactive Technologies and PECI.

Biases or disclosed conflicts of interest - none

Residential LED Subcommittee meetings: • 4 meetings: Oct 12, 2012; Oct 30, 2012; Nov 6, 2012; Jan 7, 2013• Met with manufacturers and retailers at October 2012 Energy Star

Partner meeting to vet product availability

Addressing Committee IssuesFlicker: Tracking standards under development ENERGY STAR - Specification under development (2014) NEMA LSD 49-2010, ”Solid state lighting for incandescent replacement—

best practices for dimming” http://www.nema.org/stds/lsd49.cfm IEEE PAR1789 http://grouper.ieee.org/groups/1789/

Dimmability compatibility: program design options Product specifications – which elements predict quality (efficacy, CRI PF):

Subcommittee participating with West Coast Lighting Group. Will be comparing notes with CA utilities’ approach to quality.

BPA regional promotion will test in-store materials to assist consumer. BPA regional lighting promotion will request product return information from

participating retailer (number and reason).

Committee Recommendation for 2013 Present Energy Star LED bulbs to Regional

Technical Forum:• Expect most measures to pass TRC based on

preliminary analysis

• Energy Star spec and above allows programs to focus promotions on high quality products

• Provides opportunity to test return rate of this product class

Further Research Regular data collection to track from retail

• Products available at retail that meet spec

• Sales volumes

• Changes in stocking practices

• Current pricing

• Rate/reason for product returns

Proposed Sunset Date Return to the RTF in March 2014 with

product sales data:•Effective Date of Energy Star Integral LED Lamp Update−Currently on draft 3−Expected to go into effect early 2014

•Rapid changes to technology, costs, standards that effect measure savings by more than 10%

Next Steps

Run programs!Collect dataReturn to the RTF in March 2014 with

program data to help inform updated measures and possible other delivery channels

RTF Proposed Motion:

“I _________ move that the RTF approve the Integral LED Lamps UES measure and assign it to a “Proven” category with “Active” status and a sunset date of March 1, 2014.”
