Project Objectives
City Wide EECBG and Guaranteed Energy Savings Performance Contracts
Reduce Utility Consumption & Expense Across City
Support Achievement City’s Sustainability Plan Goals
Fund Needed Work to Alleviate Strained Capital Budgets
Implement Leading Technologies Such As LED Street Lighting
What is Performance Contracting?
Energy Efficiency and Capital Improvement Projects that are Funded Entirely Through Resulting Energy and Operational Savings Which is Guaranteed by the Energy Services Contractor
Enabled by F.S. 489.145
Bundled Package of Energy Conservation Measures (ECMs) that Provides an Overall Self-Funding Program
Savings Must be Guaranteed by the ESCO
Total Project Must Fully Fund in a Term of 20 Years or Less
Project Cash Flow Must be Positive Each Year of the Term
100% Self Funded Projects
Guaranteed savings allows for funds that
would have been spent on utilities to pay for
project costs and other operational needs
Performance Guarantee &Measurement & Verification
Annual Savings Verification Report Each Year of Term
M&V Procedures Follow the International Performance Measurement & Verification Protocol (IPMVP)
Exact Methodology Determined by Project Scope, Acceptable Accuracy, and Cost Effectiveness
WPB Project Relies on Retrofit Isolation Measures Where Pre & Post Measurements Will Be Taken For Each Individual ECM
