Duke Energy’s future rooftop solar customers can expect savings while improving grid

Deal was crafted to meet South Carolina’s landmark Energy Freedom ActRooftop solar homes

COLUMBIA, SC – Solar advocates and Duke Energy have reached an agreement that could offer Duke Energy’s future rooftop solar customers significant up-front savings to go solar, while enhancing grid reliability and setting new solar pricing signals to reduce utility costs for all customers. The deal, which is intended to implement South Carolina’s popular and bipartisan Energy Freedom Act, would offer Duke Energy’s future rooftop solar customers up-front savings in exchange for their participation in a program to help Duke meet energy needs during costly peak hours.

The deal struck between solar advocates and Duke Energy achieves the goals of keeping solar installations financially attractive to homeowners and solar companies while also providing the utility the tools it needs to help the grid work at peak efficiency. The “Solar Choice Net Metering” proposal still needs approval from the Public Service Commission. Associated approvals are also necessary from North Carolina.

“This agreement is a step into the future of clean energy for South Carolina,” said Lauren Bowen, leader of SELC’s Solar Power Initiative. “It recognizes the importance of the partnerships needed between utilities, solar companies, and homeowners to expand the solar economy while keeping the grid strong, resilient, and affordable.”

“If the proposal is approved, the owner of a typical 5KW residential solar system, taking full advantage of the options under Solar Choice Net Metering, could expect to receive significant up-front savings when going solar, when paired with a newly proposed Duke Energy solar plus smart thermostat program. In the case of solar panels that are leased, the money could be used so that homeowners could install a system with low or no out-of-pocket costs,” said Bowen.

Frugal solar-powered homeowners could further save money by reducing energy use or supplying energy to the grid during the year-round peak times of 6 p.m. to 9 p.m., and in the winter hours of 6 a.m. to 9 a.m. In this way, the solar customers, as a group, will reduce the cost to Duke Energy of providing service during these more expensive hours.

“This landmark agreement uses innovative pricing to create value for all customers while creating new ways for households to embrace clean energy resources and save on their monthly bills,” stated Lon Huber, Head of Rate Design and Strategic Solutions for Duke Energy. A new pricing structure under this agreement will allow Duke Energy to charge solar customers more for electricity during those peak times, similar to surge pricing on toll roads and for rideshare services. That structure not only encourages conservation during high demand, but also helps Duke better manage resources.

The agreement with Duke Energy was brokered by a partnership of clean-energy companies and organizations including Sunrun, North Carolina Sustainable Energy Association, Vote Solar, and the Southern Environmental Law Center on behalf of the South Carolina Coastal Conservation League, Southern Alliance for Clean Energy, and Upstate Forever.

“We’re seeing extraordinary customer demand for rooftop solar, and the savings that come with it. Now, with Duke Energy’s collaboration on this innovative program, more South Carolinians will be able to reap the benefits of clean, affordable solar energy,” said Thad Culley, Senior Regional Director for Vote Solar.

“Solar Choice Net Metering is the next evolution of South Carolina’s successful solar programs,” said Peter Ledford, General Counsel and Director of Policy for NCSEA. “We’re confident this plan could work for not only South Carolina, but North Carolina too. Customers in the Tar Heel state would get expanded access to solar power under this program.”

Under the Energy Freedom Act, South Carolina utilities were required to lift the net energy metering cap on rooftop solar installations and revise net energy metering policies, but the act did not dictate how that should happen. “Net energy metering” allows solar customers to get bill credits for excess energy their panels put back onto the grid. The Solar Choice Net Metering program was created to meet the requirements of the Energy Freedom Act in a way that benefits all stakeholders.

“After years of stakeholder conversations, Sunrun is happy that all parties found a win-win approach to deliver energy choice to Duke customers,” said Sunrun’s Public Policy Director, Tyson Grinstead. Preserving net energy metering’s critical structure and allowing Duke to respond to demand requirements will help all ratepayers.”
