AI Power Demand Is Reshaping America’s Grid: Why Utility Investment and Grid Resilience Matter

The Quiet Era Has Ended: America's Steepest Load Growth Since Eisenhower

The Quadruple Engines: AI, Onshoring, Electric Vehicles, and Industrial Shift

For nearly two decades, U.S. electricity demand existed in a state of delicate, "quiet equilibrium." Although the population and economy continued to expand, significant gains in energy efficiency successfully offset the growth in absolute load. During this period, the national power grid aged quietly; while underlying risks simmered, the system managed to remain operational most of the time. However, that era of calm—sustained by using technological dividends to counterbalance rising demand—has come to a definitive end.

The United States is entering a period of load growth that is the steepest and most sustained seen since the administration of President Dwight D. Eisenhower. This historic shift is driven not by a single factor, but by four powerful, concurrent engines:

AI & Hyperscaler Data Centers: The explosive adoption of generative AI has caused computing power demands to skyrocket; clusters comprising tens of thousands of GPUs and gigawatt-scale data centers are consuming baseload power at an unprecedented rate.

Advanced Manufacturing Onshoring: Driven by national industrial policies and supply chain restructuring, the large-scale return of semiconductor, battery manufacturing, and heavy industrial facilities is generating massive demand for industrial electricity.

Transportation Electrification: The shift toward electric power for passenger vehicles, commercial fleets, and heavy-duty trucks is steadily transferring vast energy consumption—previously reliant on fossil fuels—to the electrical grid.

Economy-Wide Electrification: From the adoption of heat pumps for building heating to the electrification of industrial thermal processes, electricity is rapidly permeating every corner of modern economic life.

Faced with this surge in load—unseen in nearly 70 years—infrastructure development must keep pace with demand, a task that requires the continuous injection of large-scale, long-term capital.

Rising Energy Bills Meet Political Agenda: The Misguided Attack on ROE

However, this critical need for infrastructure development is colliding sharply with the current, complex political climate. Driven by macroeconomic inflation, rising energy costs have frequently dominated national headlines; they are not only a focal point of public concern but also a driving force behind the political agenda.

It is entirely reasonable for policymakers and regulators to focus on this issue—electricity affordability is a genuine challenge for the public, particularly for low- and moderate-income households facing a financial squeeze from housing, food, and energy costs. The government's desire to alleviate this burden is well-intentioned.

However, many current policy proposals are fundamentally misguided in their approach. In pursuit of "short-term political victories," some politicians target the Return on Equity (ROE) of utility companies, attempting to curb their capacity for infrastructure investment by forcibly capping or cutting ROE—claiming this will instantly lower consumers' monthly electricity bills.

This approach completely inverts the logic of cause and effect. Attempting to lower bills by slashing key rates of return fails to address the underlying hardship; instead, it undermines utilities' ability to raise low-cost, long-term capital, thereby inflicting lasting damage on the very business model that supports the construction of a modernized power grid. Ultimately, society will pay the price in the form of a more expensive and less resilient grid.

Unpacking the Regulated Utility Model: Why Slashing Returns Increases Long-Term Costs

The Dual Functions of the Regulated Model: Debt, Equity, and Prudential Oversight

To understand why political attacks on rates of return can backfire, one must first clarify the mechanics of the "Regulated Utility Model." As noted by Scott Aaronson—former Secretary of the Electric Subsector Coordinating Council (ESCC) and former Senior Vice President of the Edison Electric Institute (EEI)—the regulated utility model performs two unique and critical functions that cannot be replicated by any other market-based or decentralized institutional arrangement:

Long-Term Capital Formation: It enables utility companies to efficiently raise billions of dollars in long-term capital from capital markets—using an optimal mix of debt and equity—to build grid infrastructure designed to last for decades.

Rigorous Prudential Regulatory Oversight: It places every dollar invested by utility companies under the microscope of state regulators; through strict regulatory review, it ensures that every expenditure meets the highest standards of prudence, reliability, and cost-effectiveness.

This dual mechanism—where capital formation proceeds in tandem with rigorous oversight—serves as the cornerstone for balancing the scale of grid infrastructure development with the need to control costs for consumers.

ROE as the Cost of Capital: The Danger of Forcing Returns Below Fair Levels

In this business model, Return on Equity (ROE) is by no means a "windfall" profit obtained for free by utility companies; rather, it represents the cost of capital that must be paid to attract the equity portion of investment. Capital invariably flows to where returns align with risk. When regulators set the Return on Equity (ROE) at "fair and just" levels, utility companies can borrow and raise funds in capital markets at low cost—backed by a minimal risk premium—thereby building a grid capable of meeting future needs at the lowest overall cost of capital.

Conversely, if the ROE is forcibly suppressed below reasonable levels in pursuit of short-term political gains, the necessary grid investments will not simply vanish; instead, this leads to a sharp rise in the cost of capital, triggering an irreversible, vicious financial cycle:

Forced suppression of ROE → Investors demand a higher risk premium → Credit rating downgrade / rising borrowing costs → Customers pay interest for decades.

When returns are artificially reduced, Wall Street and institutional investors immediately perceive increased regulatory risk in the jurisdiction, demanding higher risk premiums. Utility companies face downward pressure on credit ratings, forcing up interest costs on debt financing. Since grid infrastructure repayments can take 30 to 50 years, these increased borrowing costs due to regulatory uncertainty will ultimately be paid as interest by end customers for decades.

As Aronson warned, "Capital is not free, and pretending it is only delays and inflates the bill."

Refuting Over-Building Claims: The True Role of Public Utility Commissions

Critics often raise a seemingly reasonable argument that the capital return mechanism of utilities creates "self-incentives," inducing companies to blindly engage in "over-building/gold-plating" to earn more returns.

This argument completely ignores the core function of the regulatory system. Preventing unwise or unnecessary spending is precisely the very reason for the existence of Public Utility Commissions (PUCs). Every proposed project must undergo extremely rigorous legal procedures by the PUC to ensure its necessity and rationality before being included in the rate base.

A deeper contradiction lies in the fact that critics' accusations of "over-construction" are severely out of touch with the current objective reality. Today, there is a broad consensus across both parties and across industries in the United States: the fundamental crisis facing the US power grid is not "over-investment," but rather severe under-investment. From withstanding extreme weather events like hurricanes and wildfires to defending against advanced cyberattacks; from building interstate transmission lines to eliminate bottlenecks to addressing the massive amounts of clean energy and new load projects waiting for years in the interconnection queue—society as a whole is demanding that the power grid take on more functions. Reducing the financing capacity of utility companies at this critical juncture not only fails to curb so-called "over-construction," but also artificially stifles the pace of modernizing the power grid.

Resilience is Designed, Not Retrofitted: Beyond Data Centers

Facing Climate Disasters and Cyber ​​Threats: A Grid for Every Community

Current discussions regarding utility capital investment often fall into the trap of assuming that grid upgrades exist solely to meet the data center demands of Big Tech companies. However, the profound value of grid resilience extends far beyond data centers alone.

Drawing on the extensive practical experience of Scott Aaronson—former Secretary of the Electricity Subsector Coordinating Council (ESCC)—in leading national infrastructure security efforts and addressing cross-state security threats, it becomes clear that a well-funded, robust grid system is directly linked to the survival and safety of countless households in the face of increasingly severe natural disasters and man-made threats.

For ordinary households and communities, investment in a modernized grid means:

Hardening Against Extreme Weather: As hurricane seasons intensify and wildfire risks spread, hardening transmission and distribution infrastructure can directly reduce the incidence of widespread power outages.

Mitigating Cyber ​​and Physical Threats: With the increasing digitalization of power systems, defending against sophisticated cyberattacks and physical sabotage targeting critical nodes requires continuous, system-wide security upgrades.

Preventing Regional Isolation: Ensuring that isolated regions lacking support from neighboring power markets do not become paralyzed during sudden incidents, and enabling cross-regional mutual aid through enhanced transmission redundancy.

Resilience cannot simply be retrofitted after a storm passes or a disaster strikes; it must be designed into the power system from the very beginning—a process that relies on sustained, large-scale capital investment and the support of regulated business models.

The VPP & DER Paradox: Half-Assets Without a Funded Mainframe Network

In recent years, with the rising popularity of concepts like Distributed Energy Resources (DERs) and Virtual Power Plants (VPPs), some advocates have argued that decentralized local resources could gradually replace the need for infrastructure investment in the traditional, large-scale grid. While well-intentioned, this perspective overlooks the systemic logic of the power grid.

Undeniably, resources such as distributed photovoltaics, residential energy storage, and smart load control are invaluable for providing localized flexibility, and we should welcome the integration of as many such assets as possible. However, we must clearly recognize that the true value of these distributed resources depends entirely on the health of the underlying "mainframe grid" to which they are connected.

A distributed resource that is not part of a well-funded, well-operated backbone network is merely a "half-asset"—and a highly vulnerable one at that.

Should the backbone network fail or transmission and distribution lines age and break, local DERs and VPPs are simply incapable of independently sustaining regional power dispatch and frequency stability. Consequently, diverting capital away from backbone grid infrastructure to place excessive bets on decentralized assets creates an "illusion of resilience" that mistakes the cart for the horse. Only by building a robust, well-capitalized, and structurally sound large-scale grid can distributed energy resources truly fulfill their intended role as a complement to the system.

Protecting Low-Income Consumers Through Disciplined Cost Allocation

Shielding Cleveland and Charlotte: Separating Hyperscaler Demand from Residential Rates

As the power grid undergoes a wave of expansion driven by artificial intelligence, high-performance computing data centers, and advanced manufacturing, the public and policymakers raise a most forceful and justified question: "Why should ordinary residential consumers have to share the cost of the ballooning electricity demands of tech giants?"

This concern is entirely understandable. Without intervention, blindly spreading the massive costs of system expansion across all end-user rates would impose an unbearable burden on low- and middle-income households. However, many overlook the core essence of the regulated utility model: it is by no means a tool for tech giants to extract public subsidies. On the contrary, rigorous "cost-of-service ratemaking" principles and cost allocation rules serve as the single most powerful institutional shield protecting residential rates from such shocks.

Under the regulated model, Public Utility Commissions (PUCs) adhere strictly to the "cost causation principle": the entity driving the cost increase must bear the corresponding financial responsibility. This means:

Direct Cost Assignment: Costs associated with new dedicated substations, high-voltage transmission lines, and grid interconnection upgrades—built to meet the loads of hyperscalers (which can range from hundreds of megawatts to gigawatts)—are directly assigned to and isolated within the rate bills of these specific large customers.

Rate Base Isolation: By establishing distinct commercial and industrial rate classes, regulators can ensure with precision that ordinary households in cities like Cleveland, Ohio, or Charlotte, North Carolina, never end up subsidizing the grid expansion required to power massive data centers through their monthly bills. This disciplined approach to cost allocation represents a unique strength of the traditional regulatory system—one that cannot be achieved through a political race to blindly slash utility Return on Equity (ROE).

Federal Guidance vs. State Execution: FERC’s "Show Cause" Orders

Clearly defining the boundaries of authority and responsibility between federal and state regulators is crucial when addressing cost allocation and consumer protection. The Federal Energy Regulatory Commission’s (FERC) latest policy direction—including its issuance of "Show Cause" orders—clearly delineates this governance framework.

FERC’s policy aims to drive Regional Transmission Organizations (RTOs/ISOs) and interstate transmission networks to establish transparent standards for cost attribution:

Federal Policy Direction: FERC uses regulatory mechanisms to guide the principles of interstate transmission cost allocation—particularly for large-scale transmission projects of national strategic importance—ensuring that costs are shared among those who derive broad regional economic and reliability benefits.

State-Level Execution: FERC’s directives clarify that the ultimate allocation of approved transmission and supply costs down to end-use retail customers falls within the exclusive jurisdiction of State Public Utility Commissions (PUCs).

State regulators possess the direct statutory authority and local insight needed to fine-tune local utilities' ROE and rate structures, thereby striking a dynamic balance between maintaining capital attractiveness and ensuring rate affordability. Shifting the focus from "arbitrary ROE cuts" to "rigorous cost attribution and PUC oversight" is the correct path toward genuinely protecting low- and moderate-income groups and achieving sustainable infrastructure development.

Building a Grid for Our Grandchildren: A Call for Rational Dialogue

The Historical Parallel: Replicating the Original Electrification Wave

Looking back at the history of the U.S. power grid, the difficult choices we face today are not unprecedented. In the early 20th century, the United States utilized the "Regulated Utility Model" to raise the immense long-term capital needed to build the world's largest and most reliable infrastructure system at the time, ultimately achieving nationwide, cross-regional electrification (the "Original Electrification Wave").

Today, as we stand at the historic intersection of an explosion in AI computing power, the reshaping of the manufacturing sector, and the deep electrification of society, we find ourselves at a strikingly similar critical juncture. The key tools required to build a next-generation, modernized grid are already within our grasp: a time-tested business model, rigorous regulatory oversight, and fair returns on capital. This mature framework not only enables utilities to drive large-scale construction at the lowest cost of capital but also effectively safeguards the vital interests of low- and middle-income residential customers through institutional protections.

A Call for Rational Dialogue: Long-Term Vision Over Short-Term Victories

We must clearly recognize that arbitrarily suppressing a utility's Return on Equity (ROE) to force down earnings will not lower customers' electricity bills next month.

Utility infrastructure investments have exceptionally long lifecycles. The capital assets raised and deployed today will be paid off gradually over their 30- to 50-year operational lives, ultimately serving our grandchildren. Decisions that curtail a utility's financial capacity in pursuit of short-term political victories do not simply vanish; they manifest as higher long-term borrowing costs and a more vulnerable grid system—with negative consequences that will far outlast the tenures of the officials who made those decisions.

The core issue today is whether we can build a modernized grid capable of supporting our nation's economy and competitiveness for the next fifty years—and the heavy price we will pay if we fail to do so. The only rational path forward is for regulators (PUCs) to collaborate with utility companies and all stakeholders to set the Return on Equity (ROE) in a scientifically grounded and impartial manner at both state and federal levels. We must not undermine the utility model precisely when its strength is most needed; instead, by relying on rigorous regulation and reasonable business returns, we should work together to build a resilient, safe, and long-lasting power infrastructure.
