Energy efficiency and DR
The Intersection of DR and Controlled
Streetlighting

Winter peaking locales can see 30 to
60 minutes of early morning overlap

Distribution system based events can
have 100% overlap in evenings
Up to 40% of a city’s energy load can
be attributed to streetlights

Streetlights comprise 6% of NYC DOT
energy usage
