Grayslake Community HSD 127

Guaranteed Energy Savings Project with Solar PV


Total Contract

2.68 MW

Solar PV Size

$9.8 million

Solar Net Savings (25 yrs)

Project Description

Grayslake School District 127 is a public high school district with two schools: Grayslake Central HS and Grayslake North HS. The District hired Performance Services to complete a much needed guaranteed energy savings project. A significant part of the project was integrating multiple building automation systems to a single platform for optimal energy savings and control.

Looking for further ways to reduce energy costs, the District decided to implement a 2.68-megawatt solar power system on campus with two roof-mounted arrays and one ground-mounted array. Expected net savings from the solar arrays is $9.8 million over 25 years. The solar project was completed in September 2017.
