Duke Energy Launches New Demand Response Program to Support South Carolina's Growing Grid

The PowerShare Storage program allows participating customers to enroll their energy storage systems and earn bill credits while assisting in maintaining a reliable grid during times of high demand. This initiative is particularly crucial as the Carolinas continue to experience growth, leading to increased energy demands.

Tim Pearson, South Carolina president for Duke Energy, emphasized the importance of this program: "It's a priority for us to save every dollar we can for our customers, who are essential partners in our work to modernize and maximize the grid and keep it operating reliably for everyone." He added that the program is a key innovation in alignment with the South Carolina Energy Security Act of 2025.

Energy storage systems function as backup power sources, capturing surplus energy when it's available and delivering it when demand peaks. This capability is essential for enhancing grid reliability and accommodating renewable energy generation. By participating in the program, nonresidential customers can manage their energy costs while contributing to the overall stability of the electric grid.

Currently, nearly 500,000 customers within the Carolinas engage in Duke Energy’s demand response programs, which help lower system costs and strengthen grid reliability for all customers, not just those enrolled in the programs.

Duke Energy’s PowerShare Storage program provides nonresidential customers with multiple incentive opportunities, making participation financially beneficial:

These combined incentives provide participating customers with predictable financial returns for making stored energy available during critical periods of demand.

By enrolling in the PowerShare Storage program, customers allow Duke Energy to temporarily draw from their storage systems between 30 and 36 times a year, with each event lasting no longer than four hours. Importantly, customers retain flexibility within the program, with the option to opt out of up to four events each year—two of which can occur during winter months—while still remaining eligible for bill credits.

The program is set to commence operations in South Carolina in August 2026, and Duke Energy encourages interested nonresidential customers to reach out to their utility account representatives for more information.

Duke Energy's PowerShare Storage program represents a significant step forward in energy management for nonresidential customers in South Carolina, aligning economic incentives with the urgent need for grid reliability. As the company continues to execute its energy modernization strategy, customers can expect innovative solutions that not only support their financial well-being but also contribute to a more sustainable and resilient energy future.
