NYSERDA

NYSERDA have traditionally funded demand reductions (kW) in preference to usage reductions (kWh), the theory being that reduction in use of transmission and distribution infrastructure, obviating T&D build-out, was more important to the participating utilities than reduction in generation.

NYSERDA have now reversed that bias.

Below is a letter we received last week from NYSERDA related specifically to LED retrofits, some of which involve exterior lighting, never a peak-demand reduction energy conserving measure. The bracketed words and designations are added for clarity.

“As per our conversation, this is our current stance on LEDs:

“LEDs are now eligible technology and they are being aggressively adopted by many of our lighting contractors.  This is exciting for everyone, but we want to make sure that applicants are installing reliable technology.  As a result, we are requiring the criteria listed below for performance projects including kWh savings from LED lighting.

“These criteria are based upon the standards addressed by the DOE’s Energy Star program for solid-state lighting.  (The applicant will probably need to request this info from the LED manufacturer(s))

  1. Independent IESNA LM-79 test data to verify Light Output, Luminaire Efficacy, CCT, and CRI
  2. Independent LM-80 test data from LED Manufacturers at 55 C, 85 C, and a 3rd temperature of the manufacturers choosing, usually higher temp.
  3. IES File in LM-63 format to verify photometrics.

“Note:  The DOE actually has a 4th criteria, but this is not required under our (NYSERDA) program.

  1. L(M)-70 Lifetime and written explanation of how it was determined, and a complete description of the thermal management of the luminaire, or something similar

“Here’s a link to the (DOE) Energy Star page for Commercial LED Lighting:

“As the Energy Star standards evolve, it is likely that our requirements will as well.  In general, please discuss any planned LED projects with us and expect that these applications may take more time to process than usual.

“Related to run hours, as we discussed, our programs are now entirely kWh based.  The run hours (do) not have to coincide with (facility) peak demand to receive incentives (cash rebates).”

This is a very encouraging development. The caveat related to “more time to process than usual” is the one hindrance to LED deployment with NYSERDA assistance.
