Green Source Advantage Solar Farm

Green Source Advantage Program –
Solar Energy Project

Solar project to offset 25% of carbon emissions from city buildings, create nearly 500 new jobs, and save the City $2 million in energy expenses

The Charlotte City Council voted on Monday, Feb. 24, 2020, to participate in the Duke Energy Green Source Advantage (GSA) Program, which will enable the City of Charlotte to move forward with a 35-megawatt, utility-scale solar energy project – and makes Charlotte the nation's most populous city to acquire new renewable energy through a utility green tariff. The City will partner with Carolina Solar Energy, a North Carolina-based, solar energy company, and Ecoplexus, an international solar energy company with offices in Durham, NC, to build the solar farm, which is expected to be fully operational by 2023.

The solar energy project, which will help offset about 25% of carbon emissions from city-owned buildings over the next 20 years, helps advance the City's Strategic Energy Action Plan (SEAP). The SEAP was adopted unanimously by the City Council in December 2018 and provides the roadmap for Charlotte to become a low-carbon City by 2050, aligning with the Paris Climate Agreement. As part of its goals, the City aims to achieve 100% zero carbon municipal buildings and fleet by 2030.

The solar energy project is expected to save the City nearly $2 million in energy expenses over 20 years and will improve air quality in the region by reducing harmful pollution.  In addition, it is expected to create 428 jobs in the region, produce enough electricity that equates to powering 10,000 homes annually, and reduce carbon emissions equivalent to removing 12,000 passenger vehicles from the road.

The GSA program allows large customers to select and negotiate directly with a renewable energy company of their choice, thereby allowing the large customer to keep all renewable energy certificates (RECs) generated by that renewable facility. The City completed a competitive procurement process to select Carolina Solar Energy, in partnership with Ecoplexus, and the planned 35 MW solar energy project.

"Not only does this 35-megawatt solar energy project get us 25% of the way towards our goal in a very short time, but it contributes to building the green economy and improves our citizens' quality of life," said Heather Bolick, Energy & Sustainability Coordinator.

American Cities Climate Challenge:

Charlotte is one of 25 cities selected to participate in the American Cities Climate Challenge, an effort to resource cities to take strong action to reduce pollution that contributes to climate change and impacts public health. As part of the challenge, the city has pledged to take bold action to reduce emissions from its transportation and building sectors. This utility-scale, solar project is an important part of the City of Charlotte's response to the challenge. The Renewables Accelerator, led by World Resources Institute and Rocky Mountain Institute, provides tools, resources and technical assistance to help U.S. cities advance ambitious renewable energy goals. Our partnership supports local governments in the American Cities Climate Challenge, the Urban Sustainability Directors Network and more as they strive to decarbonize the electricity sector.


"Charlotte is taking its climate leadership to the next level by reducing fossil fuel dependence and leveraging the power of the sun. This is a big leap forward that will help the city meets its critical climate goals, improve air quality for North Carolinians and spur job creation. This is another prime example of the bold efforts that the American Cities Climate Challenge is helping spearhead from coast to coast." Christina Angelides, Director of the American Cities Climate Challenge.

"Charlotte has shown incredible leadership as one of the first applicants to the GSA program and the first municipal customer to bring its own solar project to Duke Energy. Charlotte has paved the path for other cities in North Carolina to grow demand for clean energy solutions in Duke's territory, all while making progress toward better air quality, new jobs and workforce training opportunities. This is exactly the sort of achievement the Renewables Accelerator aims to help cities accomplish." – Ali Rotatori, Senior Associate, Rocky Mountain Institute & Renewables Accelerator technical lead

"Taking advantage of Duke Energy's Green Source Advantage program is an important move for the City of Charlotte to lower its overall carbon footprint. We're pleased our headquarters location is the first city to take this step." – Christy Daniel, Managing Director, Renewable Customer Programs and Solutions at Duke Energy


The solar energy project will move the City approximately 25% closer to its Strategic Energy Action Plan (SEAP) goal of 100% zero-carbon energy buildings. This solar energy project is expected to save the City approximately $2M in energy spend over the course of 20 years. The creation of this solar energy project will improve air quality in the region, which will result in public health benefits. In addition, it is expected to create 428 jobs in the region over the 20-year term, and reduce the carbon emissions that is equivalent to removing 12,000 passenger vehicles from the road (Source: EPA Greenhouse Gas Equivalencies Calculator).


Due to Charlotte's participation in the Green Source Advantage, this solar energy project will be created and increase the amount of renewable energy on Duke Energy's regional grid, which the City of Charlotte pulls energy from to power its buildings, traffic lights, and more. Solar energy does not emit air pollution like coal and natural gas, and therefore improves air quality in the region, which results in public health benefits like decreased asthma. If a solar energy project is producing energy for the regional grid, then a fossil fuel power plant does not have to produce that energy, and therefore air pollution is reduced.

​To put it into context, a 35 MW solar energy facility will cover about 300 acres of land, and is projected to produce enough electricity to power approximately 10,000 homes annually.
