ESPC (Energy Savings Performance Contract)
Funding Sources for ESPC
Typical Improvements
Examples – Waste Water
Selecting and ESCO Partner
ESPC – Process
Summary
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 &
Energy Saving Performance Contracting
Purpose
o
Obtain Long-Term Energy and Cost Savingso
Leverage Existing Operating dollars to Fund Capital Projects
Alternate Procurement Mechanism that Provides Guarantees
and Financing Options
Growing Momentum in Public Sector Utilities
Promotes Development of Alternate Sources of Energy
Used by the State of Michigan and the Federal Government
