Program Background - continued
ƒ Projected Budget: $24 million (Projected Cost:$18 million)
ƒ Funding:
ƒ Utility funding | Customer billed
ƒ $1 million ARRA EECBG Grant in 2010
ƒ Goals:
ƒ Reduce energy use by 40% - Actual 48%+!
ƒ Lower maintenance costs (only lens cleaning during
fixture life, no relamping, longer life photoelectric cell)
ƒ Improve Customer Service (increased reliability of the
fixture, fewer outages)
