The $170 Billion Grid Fix: Unlocking America's Untapped Power

WASHINGTON, DC – March 19, 2026 – By Patrick Walker

A groundbreaking new analysis suggests that the solution to America's rising electricity bills and grid-related growing pains may not be building more power plants, but rather using the existing system more intelligently. According to a report released today by The Brattle Group, better utilization of the nation's existing power grid could save U.S. consumers between $110 billion and $170 billion over the next decade.

The report, titled The Untapped Grid, argues that a vast amount of the country's multi-trillion-dollar electricity infrastructure sits idle for most of the year. This is because the grid is built to handle short, infrequent periods of peak demand—like the hottest summer afternoons—leaving a massive reserve of untapped capacity. The study finds that the U.S. electric grid operates at only 53% of its total capacity on average. Improving that utilization by just 10% could slash electricity rates by an estimated 3.4%.

"Rising electricity rates and accompanying energy affordability concerns are a national challenge that utilities and energy regulators are under pressure to address," said Ryan Hledik, a Brattle Principal and coauthor of the report. "Making better use of the existing power system is a cost-effective solution to the problem, and our study quantifies the significant scale of the opportunity."

Silicon Valley's Power Play

The push for a more efficient grid isn't just coming from consultants. The report was commissioned by GridLab and the newly formed Utilize Coalition, an industry group whose founding members include tech and energy heavyweights like Google, Tesla, Carrier, SPAN, and Renew Home. Their involvement highlights a critical shift: the world's largest electricity consumers and technology providers are now driving the conversation on grid modernization.

For companies like Google, the need is existential. The explosion of artificial intelligence and the data centers required to power it are creating unprecedented electricity demand, with some estimates suggesting data centers already consume 2-3% of all U.S. electricity. This voracious appetite is reportedly running up against power constraints, making faster and cheaper grid connections a top corporate priority. A more efficiently managed grid could accelerate interconnection for new data centers and advanced manufacturing plants by several years.

Meanwhile, companies like Tesla and Carrier see a massive business opportunity. Tesla's energy storage division, which saw 125% year-over-year growth in 2025, produces the batteries and software essential for grid flexibility. Its concept of a Virtual Power Plant (VPP), which aggregates distributed resources like home Powerwall batteries to provide grid services, is a cornerstone of the utilization strategy. Similarly, Carrier is developing smart HVAC systems with built-in batteries that can shift energy use away from peak hours, turning a major source of demand into a grid-stabilizing asset.

"Increasing grid utilization is one of the most powerful levers America can pull to meaningfully reduce the increasing cost of electricity in the near-term," said Ian Magruder, Founder and Executive Director of the Utilize Coalition. This alignment of interests—between the tech giants who need the power and the companies who sell the tools to manage it—has created a powerful lobbying force for change.

The Toolkit for a Modern Grid

The Brattle report outlines a broad suite of existing technologies and policies that can unlock the grid's latent capacity. The core idea is to flatten the peaks and fill the valleys of electricity demand. Instead of exclusively building expensive new power plants and transmission lines to serve a few hours of peak use, utilities can use a more dynamic approach.

Key strategies include:

• Demand Flexibility: Using smart devices—like thermostats, EV chargers, and water heaters—and financial incentives to encourage consumers to shift their energy use to times when power is cheap and plentiful.
• Distributed Energy Resources (DERs): Leveraging customer-sited resources like rooftop solar panels and battery storage to both reduce demand and inject power back into the grid when needed.
• Grid-Enhancing Technologies (GETs): Deploying advanced sensors, software, and power-flow control devices that allow grid operators to see and manage congestion on the existing network in real-time, pushing more power through the same wires.
• Improved Rate Design: Moving away from flat-rate pricing toward time-of-use rates that better reflect the true cost of generating electricity at different times of day, giving consumers a clear financial signal to conserve during peak hours.

This approach represents a fundamental shift from the 20th-century model of building infrastructure to meet projected demand. In the new model, new loads like data centers and EV charging fleets are strategically managed to soak up excess capacity, paying for a portion of the existing system and thereby lowering the cost burden for all other customers.

Overcoming Decades of Inertia

Despite the clear financial benefits and technological readiness, the path to a fully utilized grid is fraught with regulatory and institutional hurdles. For decades, the utility business model has incentivized building new infrastructure, as capital investment is the primary way regulated monopolies grow their earnings. A model based on optimization and efficiency challenges this deep-seated paradigm.

Public Utility Commissions (PUCs), the state bodies that regulate utilities, often struggle to evaluate the benefits of non-wires alternatives and may be hesitant to approve new rate designs or programs that seem less certain than a new power plant. This conservatism is compounded by what some analysts call an "Iron Triangle" of special interests that benefit from the status quo of large capital projects.

Furthermore, implementing demand-side solutions at scale requires a level of consumer engagement and trust that can be difficult to achieve. Equity is also a major concern; grid modernization efforts must ensure that benefits and costs are distributed fairly, and that low-income communities are not left behind or disproportionately burdened by new rate structures.

The Utilize Coalition is already working to translate its report into action, backing a bill in Virginia that would require utilities to begin quantifying and disclosing their grid utilization rates—a first step toward managing what can be measured. The success of such policy initiatives will determine how quickly the grid's untapped potential can be converted into tangible savings for American households and businesses.
