Lighting Upgrade Project

Client: City of Perry
Location: Perry, Michigan
Project Overview:

The Energy Alliance Group of Michigan (EAG) was selected by the City of Perry, Michigan to assess and develop a solution for their exterior lighting concerns among their downtown streets, municipal buildings and parking areas.

The existing metal halide lighting systems had a number of drawbacks:

• Insufficient illumination including dark spots between poles, which were a security concern in the downtown area.
• High electricity costs due to poor energy efficiency performance.
• High maintenance expenses resulting from bulb replacement costs and the labor required for the change outs.

EAG selected induction lighting as the most economical and energy efficient solution to address Perry’s lighting concerns. Induction lighting is a proven technology whose benefits include:

• Better illumination with an “instant-on” brighter, whiter light that eliminated the dark spots.
• Reduced energy consumption – induction is one of the most energy efficient technologies.
• Significantly lower maintenance costs with a rated operating life of 100,000 hours.

After EAG completed the replacement of Perry’s existing metal halide lighting, the city saw an immediate improvement in lighting performance and monthly cash flow. These benefits included:

• Reducing exterior lighting energy consumption by 57%
• Achieving a payback of less than five years with a savings to cost ratio of 4.35
• Removal of “rope” lighting used between poles for dark spots
• Significantly reducing maintenance costs as a result of 100,000 hour operating life and 10-year warranty
• Receiving a $4,000 rebate from Consumers Energy, the city’s utility provider
