Duke Energy helps expand solar in North Carolina

The City of Charlotte has become the first municipality to execute a renewable power agreement under Duke Energy’s Green Source Advantage (GSA) programme – further expanding solar energy in North Carolina, US.

The 35 MW solar facility will be constructed in Iredell County. Under a 20-year power purchase agreement, Duke Energy will secure zero carbon power to partially offset the city of Charlotte’s energy demand.

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, North Carolina, to build the solar farm, which is expected to be fully operational in 2022. The facility will be along Tomlin Mill Road near Statesville.

The GSA programme is an outgrowth of 2017’s landmark solar legislation in North Carolina. Programmes such as solar rebates for customers and solar leasing were also part of that legislation. In 2015, Duke Energy’s pilot programme for GSA – the Green Source Rider – had companies like Google and Cisco participate.

The GSA allows large customers to offset its power purchases by securing renewable energy from projects connected to the Duke Energy grid. The customer may keep the renewable energy certificates (RECs) from the projects and use the energy purchased to satisfy sustainability or carbon-free goals.

The move fits with Charlotte's goal to have its municipal fleet and facilities be fuelled by 100% zero-carbon energy sources by 2030.

Participation in Green Source Advantage means the City of Charlotte will offset a portion of the energy supplied to its municipal operations with renewable energy. The city and the solar developer agreed on the specific project and additional costs associated with energy from the facility. Other Duke Energy customers will not pay for any part of the project.

Overall, 600 MW of capacity is available under the GSA programme for large Duke Energy customers in North Carolina. Currently, Duke Energy maintains more than 3300 MW of solar power on its energy grid in North Carolina and operates 40 solar facilities. North Carolina currently ranks No. 2 in the US for overall solar power.
