Duke Energy’s $30 Million Microgrid and Energy Storage Project Approved
Duke Energy’s microgrid project in Madison County, North Carolina has been approved by the North Carolina Utilities Commission (NCUC).
In the town of Hot Springs, the company will proceed with a solar and battery-powered microgrid system that will help improve electric reliability, provide services to the overall electric system and serve as a backup power supply to the town of more than 500 residents.
The Hot Springs microgrid will consist of a 2-megawatt (AC) solar facility and a 4-megawatt lithium-based battery storage facility. According to Duke Energy, the microgrid will not only provide a safe, cost-effective and reliable grid solution for serving the Hot Springs area, but the microgrid will also provide energy and additional bulk system benefits for all customers. This will include reliability services to the electric grid, such as frequency and voltage regulation and ramping support and capacity during system peaks.
The project is part of Duke Energy’s plan to meet power demand by balancing public input, environmental impacts and the need to provide customers with safe, reliable and affordable energy.
Another component of that plan is in the city of Asheville where Duke Energy will connect a 9-megawatt lithium-ion battery system at a Duke Energy substation site in the Rock Hill community. The battery will primarily be used to help the electric system operate more efficiently and reliably for customers.
Together, the two projects will cost around $30 million and should be operational in early 2020.
Also in the region, Duke Energy is closing a half-century-old, coal-fired plant in Arden by January 2020 – and replacing it with a new 560-megawatt cleaner-burning combined-cycle natural gas plant.
