South Cary Solar Array

The South Cary Water Reclamation Solar Array was placed in service in December 2012 and has the capacity to generate 2,150 MWh annually of electricity. This system consists of nearly 6,000 solar panels that generate enough energy to offset roughly 1,500 tons of greenhouse gas emissions annually. Power generated is returned to the distribution grid as a renewable source of energy. 

During the initial phase, Cary leased approximately eight acres to FLS Energy with no upfront costs or maintenance costs during the life of the lease. Cary purchased the system in 2022, further advancing renewal energy initiatives.

Background

Beginning in 2007, the North Carolina General Assembly implemented the Renewable Energy and Energy Efficiency Portfolio Standard (REPS), which mandates that electric utilities meet 12.5 percent of their electric needs through renewable sources. This act has furthered the development of private infrastructure for the purposes of generating renewable energy for sale to the Utilities.

Following this legislative action, Cary investigated the possibility of installing renewable energy generation equipment, specifically a photovoltaic system. The South Cary Water Reclamation Facility (SCWRF) was selected based on available space, suitability for the efficient collection of solar energy with no impact on operations, and future expansion plans.

FLS Energy was selected as its solar energy partner. FLS Energy had considerable local experience developing solar projects in North Carolina, including installations at SAS and a number of rooftop projects in the Triangle area. In 2016, FLS Energy was purchased by Cypress Creek Renewables, who subsequently took over the operation of the solar installation at the South Cary Water Reclamation Facility. Cypress Creek Renewables is one of the nation's leading developers of solar projects.

In 2022, Cary became the proud owner of the 2.15-megawatt solar facility at SCWRF through an asset purchase agreement with Cypress Creek Renewables. The acquisition aligns with Cary's commitment to advancing renewable energy and reducing carbon emissions.
