Why Goldman Sachs’ Warning Is a Call to Action for Grid Modernization
Earlier this month, Bloomberg News, through reporting by Naureen S. Malik, published a striking assessment: nearly all US power grids could lose critical reserve margins by 2030 as electricity demand surges, driven largely by artificial intelligence, data centers, and electrification.
That conclusion, informed by analysis from Goldman Sachs Group Inc., should not surprise anyone working closely with the electric grid. But seeing it articulated so plainly – and so publicly – matters.
Goldman Sachs’ Samantha Dart and Carly Davenport deserve real credit for naming the problem without hedging: the US is simply not adding usable grid capacity fast enough. And unless that changes, reliability risks, higher costs, and constrained economic growth will follow.
This Is Not Just About Generation – It’s About Getting Power Where It’s Needed
Reserve margin targets, typically around 15%, were developed for a very different grid era – one defined by steady demand growth, ample transmission headroom, and generation located close to load.
Today, demand growth looks nothing like that world.
AI-driven data centers are appearing in concentrated clusters, often requiring hundreds of megawatts of firm, high-quality power delivered continuously. Electrification of transportation, industry, and heating is accelerating in parallel. And all of it must be served by a transmission grid largely built decades ago.
In many regions, generation capacity technically exists. What’s missing is the ability to deliver that power reliably. Aging conductors, thermal bottlenecks, congestion, and long permitting timelines have transformed nominal capacity into stranded capacity. On paper, margins may look acceptable. In practice, operators are increasingly stretched during heat waves, cold snaps, wildfire events, and extreme weather.
Two Decades of Delay Have Made the System Brittle
For much of the past 20 years, the US grid evolved under the assumption of slow, incremental change. Transmission expansion lagged. Reconductoring projects were deferred. Substations aged. Investment focused on short-term efficiency rather than long-term resilience.
At the same time, climate stress intensified. Higher ambient temperatures reduce conductor ampacity. Wildfire risk forces operating constraints and shutdowns. Severe storms drive higher outage and restoration costs. The result is a grid with less usable capacity at precisely the wrong time.
Unlike more centrally coordinated systems such as China, the US grid is fragmented across thousands of utilities and multiple regulatory frameworks. Large, greenfield transmission projects face permitting timelines measured in decades – timelines that simply do not match the pace of demand growth.
The Fastest Grid Capacity Gains Are Already Within Reach
What often gets lost in national discussions is that meaningful grid expansion does not always require new corridors or new towers.
One of the fastest, most effective ways to increase capacity is by fully utilizing existing transmission infrastructure.
Advanced Conductors and Grid-Enhancing Technologies are already proving what’s possible:
- Advanced Conductors can double the capacity of existing lines
- They operate at higher temperatures with dramatically lower sag
- They reduce losses, improve efficiency, and strengthen reliability margins
- They can be installed on existing structures, avoiding years of permitting delays and environmental impact
For utilities under pressure to deliver capacity quickly, these solutions unlock large blocks of transmission headroom in years – sometimes months – rather than decades.
Grid-enhancing technologies, including dynamic line ratings and advanced monitoring, further expand usable capacity by allowing operators to rely on real-world conditions rather than conservative static assumptions rooted in another era.
Together, these tools directly address the bottlenecks highlighted by Goldman Sachs: localized, physical constraints that no amount of generation alone can solve.
Rising Bills Are a Consequence of Delay
Goldman’s observation that rising utility bills will become a political issue in dozens of states reflects what customers already feel. Bills are increasing due to:
- Congestion and inefficiency costs
- Emergency hardening investments
- Deferred maintenance coming due
- Tighter capacity margins under stress
What customers are not yet seeing at scale are the savings that come from proactive, high-impact grid upgrades. Delaying modernization does not avoid cost – it compounds it, while increasing outage risk and limiting economic growth.
The AI Race Is Also a Transmission Race
Goldman’s warning that grid constraints could undermine US competitiveness in artificial intelligence may sound dramatic, but the logic is straightforward: compute follows power.
Data center developers increasingly prioritize regions where large amounts of electricity can be delivered reliably and quickly. Where transmission capacity cannot be unlocked, investment simply goes elsewhere. This is not a future scenario – it is happening now.
A Clear Path Forward
Bloomberg and Goldman Sachs have elevated a critical issue into sharper focus. The next step is execution.
Advanced Conductors, reconductoring strategies, and grid-enhancing technologies are not experimental. They are deployed, proven, and already delivering results across voltage levels and regions.
The choice facing utilities, regulators, and policymakers is not whether demand will grow – it will. The real decision is whether the grid is modernized with tools equal to today’s challenges, or constrained by assumptions and technologies from another era.
If we act decisively, the grid can once again become an enabler of reliability, affordability, and economic competitiveness. If we do not, it risks becoming the limiting factor.
The warning has been issued. The solutions are available. Now is the time to deploy them at scale.
