The Next Megawatt May Already Exist

Why America's power challenge requires a capacity strategy—not simply more generation

Northern Virginia has become one of the clearest illustrations of America's emerging power dilemma.

An NBC4 Washington report this week highlighted concerns that the extraordinary concentration of data centers across Northern Virginia is placing increasing strain on the region's electrical infrastructure, raising questions that now extend beyond electricity prices and economic development into grid resilience and national security.

The concern deserves attention. But the more consequential question is what we do about it.

For much of the past several decades, electricity demand in the United States grew slowly enough that utilities could plan generation and infrastructure on relatively predictable timelines. Artificial intelligence, hyperscale data centers, advanced manufacturing and broader electrification are changing that equation. Gigawatt-scale concentrations of new demand are emerging on timelines dramatically shorter than those required to permit, finance and construct major generation and transmission infrastructure.

The conventional answer is straightforward: America needs more power.

It does. But that answer is incomplete.

From an energy shortage to a capacity problem

What many of America's fastest-growing regions increasingly face is not simply an absence of electricity. It is an inability to deliver sufficient power, at a particular location and time, through the existing electrical infrastructure without compromising affordability or reliability.

That distinction creates another potential source of capacity: the demand side of the system.

Consider a large data center, hospital, commercial building or industrial facility. Its electrical requirement is not necessarily immutable. Electrical inefficiencies can be reduced. Cooling loads can be optimized and shifted. Energy can be stored during periods of available capacity and discharged when the grid is constrained.

Individually, these improvements are usually characterized as energy-efficiency projects.

Aggregated across dozens or hundreds of large facilities, they begin to look like infrastructure.

Capacity as Infrastructure

This leads to a different way of approaching America's power challenge.

Before assuming every incremental megawatt of economic growth requires an incremental megawatt of new grid infrastructure, we should determine how much usable capacity can be recovered from the infrastructure already operating.

This is the premise behind Capacity as Infrastructure.

A megawatt of reduced demand is not identical to a megawatt of generation. Nor should every efficiency improvement automatically be treated as grid capacity. Location, timing, persistence, reliability and dispatchability all matter.

But when demand reduction occurs reliably at the location and time the electrical system is constrained, its infrastructure value can become substantial.

The Department of Energy is increasingly pointing in the same direction. Its work around rapidly growing data-center demand includes not only additional generation and transmission, but energy efficiency, demand flexibility and onsite storage—recognizing that large electricity consumers can become participants in grid reliability rather than simply sources of additional load.

Reduce. Shift. Dispatch.

We believe a comprehensive capacity strategy requires several complementary layers.

First, reduce the underlying electrical requirement. Power-conditioning and optimization technologies can improve electrical performance and reduce unnecessary demand across large facilities.

Second, shift flexible loads. Commercial buildings and other large facilities contain significant thermal mass. Intelligent controls can move portions of cooling demand away from the periods when the electrical system is most constrained without compromising the building's mission.

Third, store and dispatch energy. Advanced storage creates another layer of flexibility, allowing facilities to reduce their dependence on the grid during critical periods.

The combination is more consequential than any individual technology.

Reduce the baseline. Shift the flexible load. Dispatch stored capacity when it is needed.

Then aggregate the results.

A single optimized building represents an efficiency project. A portfolio producing 50, 100 or 500 MW of verified demand reduction and flexibility begins to represent an infrastructure resource.

Northern Virginia could be the proving ground

Few places provide a better laboratory than Northern Virginia.

The region's data-center economy is strategically important to Virginia and to the United States. The objective should therefore not be to constrain the industry's growth. It should be to determine how to accommodate that growth while protecting reliability, affordability and the communities surrounding it.

That means pursuing new generation and transmission aggressively where necessary.

It should also mean making the existing data-center footprint dramatically more electrically productive.

Imagine treating Northern Virginia's largest data centers not simply as individual electricity consumers, but as a coordinated capacity portfolio. Electrical optimization reduces baseline requirements. Thermal optimization provides flexibility. Storage supports facilities during constrained periods.

The resulting capacity is measured, verified and aggregated.

The question then changes from:

"Where will we find enough power for the next generation of data centers?"

to:

"How much new power do we actually need after optimizing the infrastructure we already have?"

That question should be asked well beyond Northern Virginia.

Washington. New York. Philadelphia. Pittsburgh. Phoenix. Dallas. Atlanta. Silicon Valley. Any market where economic growth is colliding with constrained electrical infrastructure is a candidate for a Capacity Strategy.

Build what we need. Recover what we can.

America will need substantial investment in generation, transmission, distribution and grid modernization. Capacity as Infrastructure is not an argument against those investments.

It is an argument for making them smarter.

The fastest and least expensive megawatt available in a constrained market may sometimes be the one that does not have to be generated, transmitted and delivered in the first place.

The infrastructure industry has spent decades learning how to finance and value the production of electricity. The next opportunity may be learning how to identify, aggregate and value capacity hidden inside the infrastructure we already have.

Build what we need. Recover what we can. Manage both intelligently.

That is the Capacity Strategy.
