  • Enables innovative multi-industry risk-sharing for new carbon-free energy generation
  • Supports Duke Energy’s and large customers’ commitment to clean energy

CHARLOTTE, N.C., June 7, 2024 /3BL/ - Duke Energy (NYSE: DUK), Amazon, Google, Microsoft and Nucor announced agreements to explore new and innovative approaches to support carbon-free energy generation and help utilities serve the future energy needs of large businesses in North Carolina and South Carolina. The announcement was made at the White House Summit on Domestic Nuclear Deployment.

In memorandums of understanding (MOUs) signed this month, the companies proposed developing new rate structures, known as “tariffs” in the utility industry, designed specifically to lower the long-term costs of investing in clean energy technologies like new nuclear and long-duration storage through early commitments.

The proposed Accelerating Clean Energy (ACE) tariffs would enable large customers like Amazon, Google, Microsoft and Nucor to directly support carbon-free energy generation investments through innovative financing structures and contributions that address project risk to lower costs of emerging technologies. ACE tariffs would facilitate beneficial on-site generation at customer facilities, participation in load flexibility programs and investments in clean energy assets – features attractive to customers with large-scale energy needs.

The ACE framework also would include a Clean Transition Tariff (CTT) – the key feature enabling Duke Energy to provide individualized portfolios of new carbon-free energy to commercial and industrial customers. The CTT would match clean-energy generation and customer load to accelerate overall grid decarbonization. This would be a voluntary program for larger customers seeking to advance their clean energy goals, and it would include protections for non-participating customers.

Next steps and additional information

Duke Energy looks forward to working with other new and existing customers with similar energy needs and sustainability goals.

The ACE tariffs would represent new, voluntary pricing structures for Duke Energy’s large commercial and industrial customers. Duke Energy’s five-year capital plan will continue as planned and these tariffs would be subject to regulatory approvals in North Carolina and South Carolina.


In this new era of large-scale energy demand, Duke Energy is committed to working with our regulators and customers to find innovative and responsible ways to satisfy the growing need for more and cleaner energy. With the help of companies like Amazon, Google, Microsoft and Nucor, we can accelerate our service of large customer needs and the transition to cleaner energy, while reducing financial risks and supporting economic development in our communities.
