TIP 308: Demonstration of a
Demand Response Solution for
RTUs and Lighting Retrofits
NREL Lead Investigator, Michael Deru
Catalyst + Demand Response
• CATALYST as a DR asset and permanent load
reduction solution
• Catalyst’s eIQ BMS platform used to also
control lighting, water heating and plug loads
for DR
Goal
• At the end of the two-year demonstration,
NREL and TWT’s goal is to ensure that BPA
understands the feasibility, scalability, DR
potential, and programmatic requirements to
incentivize a BMS that can deliver DR and EE
through multiple commercial building assets
packaged in a single investment.
Proof-of-Concept-Pilots
• 6 sites in the PNW
– 2 drug stores
– 2 restaurants
– 1 big box retailer
– 1 casino
– 1 furniture store

Criteria for Success
• Minimally achieves an average 0.9 W/ft2 for
10-minute DR and 1.7 W/ft2 day-ahead DR
across five demonstration sites; and
• Meets a simple payback of six years from a
solely EE perspective without utility
incentives.”
