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
