While Gerard is fixing his knee, Laurent invites Chris Seiple, Vice Chairman of WoodMac Power & Renewables group, to try to make sense of the scale of the coming power demand surge and the strain it is placing on today’s US market structures.
AI-driven datacenter growth is pushing the US power system into uncharted territory. Roughly 180 GW of U.S. electricity commitments tied to datacenters represent about 30% incremental demand. Hyperscaler CAPEX is exploding. Demand is accelerating far faster than new supply can come online, setting up a near-term imbalance. In response, the U.S. utility sector is preparing for a potential $1.4 trillion investment supercycle over the next five years.
In regulated markets, utilities are under pressure to modernize cost-of-service models and deliver massive capital programs while keeping electricity affordable. Companies such as Duke Energy, Southern Company, Entergy, and CenterPoint Energy are planning investments that run into the hundreds of billions.
In deregulated markets, players like Constellation Energy, Vistra Corp., and NRG Energy face a structural mismatch: datacenters can be built faster than power plants, while price signals may not rise quickly enough to incentivize new generation. Some customers are exploring off-grid solutions, but these bring technical and economic challenges.
The conclusion is clear: load growth is staggering. Parts of the system may move toward re-regulation, but that alone will not be enough. Rapid innovation—decentralized solutions, grid-enhancing technologies, faster interconnections, and deeper digitization—will be essential as utilities relearn how to build at scale and speed.

Last year, the nuclear industry experienced something close to a gold rush. SMRs — Small Modular Reactors — became the hottest story in energy. Private capital poured in, valuations exploded, and the industry produced an impressive collection of truly bombastic promises. The backdrop is undeniably powerful: electrification is accelerating, geopolitics are reshaping energy markets, and the world needs reliable, 24/7 clean power. Nuclear has rarely enjoyed such formidable tailwinds.
The current datacenter buildout is the biggest GDP bet in America since the railroads 150 years ago. We have never seen a frenzy quite like this. The system is running on overdrive—and the cracks are starting to show.
The global market for Virtual Power Plants is assessed around 100GW (+/- 20GW). It is a 7bnUSD expected to grow at a CAGR above 20% in the next 5 years to reach 40bnUSD within a decade. VPP are a digitally coordinated flexible network of distributed resources: cheaper than central stations. They manage behind the meter assets like Solar, batteries, HVAC, EV…
Joseph J. Romm (1960–2026) was an MIT-trained physicist who became one of the most prominent voices in the U.S. climate movement after serving as Acting Assistant Secretary for Energy Efficiency and Renewable Energy at the U.S. Department of Energy in the 1990s.
