Duke Energy CEO: Agree with Administration's push to make data centers pay their fair share

Duke Energy & Data Center Demand: An Interview with Harry Sedaris

Key Concepts:

• Data Center Load Growth: Rapid increase in electricity demand from data centers.
• Fair Share Contribution: Ensuring data centers cover the costs of infrastructure upgrades needed to support their energy consumption.
• All of the Above Strategy: Duke Energy’s approach to energy generation, utilizing natural gas, solar, batteries, and nuclear power.
• Capacity Factor: A measure of how much electricity a power plant actually produces over a period of time, compared to its maximum potential output.
• Small Modular Reactors (SMRs): A newer type of nuclear reactor that is smaller and potentially more cost-effective than traditional large-scale reactors.
• Revenue Requirement: The total amount of money a utility needs to collect from customers to cover its costs and provide a reasonable return on investment.

I. Data Center Demand & Ratepayer Protection

The interview centers on the escalating electricity demand from data centers and Duke Energy’s strategy to manage this growth without burdening residential customers. President Biden is planning a meeting with tech leaders to discuss a “ratepayer pledge” – a commitment to prevent data center expansion from driving up electricity costs for homes. Harry Sedaris, CEO of Duke Energy, asserts that both demand growth and stable prices are achievable.

Duke Energy has been proactively addressing this issue for the past year and a half, structuring contracts with large data center customers (including Microsoft, Amazon, and BMW) to ensure they “pay their fair share.” Specifically, new data center contracts are designed to reduce costs for other customers over the 15-year contract life by absorbing fixed system costs. Sedaris points to Loudoun County, Virginia, as a precedent where electricity costs have decreased despite significant data center growth.

The core mechanism for this cost allocation involves calculating the “revenue requirement” – the total investment needed to build the infrastructure to power the data centers. Data centers then pay a rate based on this calculation, preventing the costs from being spread across the broader customer base.

II. Customer Collaboration & Speed to Power

Sedaris emphasizes the collaborative nature of these agreements. Data center companies have been “great partners,” actively working with Duke Energy to establish terms that protect customers while meeting their own needs. A key driver for these companies is “speed to power” – the ability to quickly connect to the grid.

To facilitate faster connections, data centers are willing to accept “curtailment” – temporary reductions in power supply – for approximately 50 hours per year. This allows Duke Energy to bring them online sooner. The CEO highlights that these companies aren’t being “politically pressured” but are proactively agreeing to these terms.

III. Duke Energy’s Capital Spending & Generation Mix

Duke Energy has a $103 billion capital spending plan. The interview details a diversified approach to energy generation, described as “all of the above.” This includes:

• Natural Gas: 5 gigawatts (approximately 3.75 million homes equivalent) of planned build-out. Gas is positioned as a reliable and cost-effective baseload resource.
• Solar & Batteries: Approximately 5 gigawatts of planned build-out, providing cheap energy and peak-handling capabilities.
• Existing Asset Optimization: Upgrading existing nuclear plants by 300MW and increasing output from existing gas plants by 1000MW. This maximizes value from current infrastructure.

The company is strategically positioned in rapidly growing states – North Carolina, Florida, and Indiana – experiencing both population and industrial (data center) demand.

IV. Nuclear Power: Reliability, Cost & Future Plans

Duke Energy operates 11 nuclear reactors, which are described as low-cost, reliable, and beneficial to customers through tax credits. In the previous year, the company achieved a record-high capacity factor of over 96% for its nuclear plants, generating $600 million in tax credits to be returned to customers.

Looking ahead, Duke Energy is exploring Small Modular Reactors (SMRs). They filed a permit in December for an SMR at the Belews Creek facility and anticipate a response from the Nuclear Regulatory Commission (NRC) within 18 months. The focus is currently on “keeping options open” and evaluating the financial implications for both investors and customers. Sedaris acknowledges the historical challenges of large-scale nuclear projects like Vogtle (over budget and delayed) but emphasizes the potential benefits of SMR technology.

V. Geographic Considerations & Customer Growth

The interview highlights the significant population and industrial growth in Duke Energy’s service territories. Charlotte, North Carolina, is experiencing an influx of 157 people per day. This growth necessitates substantial investment in infrastructure and a diversified energy portfolio. The optimal mix of gas, solar, and nuclear is determined both geographically and based on specific customer needs.

Notable Quote:

“Every new data center that we’re signing up, every gigawatt of data center is actually going to reduce the cost to our customers over the life of that contract over the 15 years, as they absorb some of the fixed costs of the system.” – Harry Sedaris, CEO of Duke Energy.

Conclusion:

Duke Energy is proactively addressing the challenges and opportunities presented by the surge in data center demand. Their strategy centers on collaborative agreements with customers, a diversified generation mix, and a commitment to protecting ratepayers. The company is focused on maximizing the value of existing assets while exploring innovative technologies like SMRs to ensure a reliable and affordable energy future for its growing customer base. The key takeaway is that responsible growth in data center capacity can coexist with stable electricity prices through careful planning and strategic partnerships.
