slide-3
SLIDE 3

A Design/Build partnership between an owner and an Energy Services Company (ESCO) to:

  • Identify Cost Saving Steams to Fund Capital Projects
  • Implement Comprehensive/Complex Efficiency Projects
  • Provide Guarantees on Savings, Costs & Performance

(Transfers Risk from Owner to ESCO)

  • Includes Engineering, Installation, Project Management, Training,

Service & Support (Turnkey)

  • Flexible Funding Options

“A mechanism for procuring and implementing capital improvement projects today, through the guaranteed energy &

  • perational savings that they create in the future.”

SLIDE 5

Utility Bill

Before

Before Performance Contract

  • Owner’s utility budget can be reduced

by replacing old inefficient equipment

Energy Saving Performance Contracting

Your Current Operating Costs

slide-6
SLIDE 6

Utility Bill Payment for Efficiency Upgrades Customer Savings

Before During Immediately begin to enjoy the savings

During Performance Contract

  • Energy Services Company develops

and installs energy efficient equipment

  • Savings monitored & verified
  • Owner pays back investment with

portion of utility savings

Energy Saving Performance Contracting

Your Operating Costs During Payback Period

Utility Bill Payment for Efficiency Upgrades Customer Savings

Before During After Enjoy the full savings

After Performance Contract

  • Owner keeps all the savings

after initial investment is paid
