Power demand is surging: Who will benefit from a new electricity supercycle?
The US is entering a new era of electricity demand growth – a power supercycle. This will mean a seismic shift in how capital is deployed across energy generation, grid infrastructure, and storage technologies, and significant investment opportunities for Robeco’s Smart Energy strategy.
まとめ
- AI, electrification and decarbonization are accelerating power demand
- Legacy grids and infrastructure underinvestment are limiting supply
- Demand-supply mismatch is driving a new investment supercycle
The US is at the epicenter of this acceleration, with power demand in the next decade expected to increase almost three times the pace of the last two.1 This will bring its total consumption from 4,100 TWh in 2024 to 5,300 TWh in 2035.2 Such an increase is equivalent to the combined annual consumption of France, Germany and Italy.3

US power demand in the next decade is expected to increase almost three times the pace of the last two
The primary demand drivers are clear:
Data centers / AI computing: Already big users of electricity, data center power consumption is expected to increase at an annual rate of 15% (CAGR) by 2035. Data centers already account for around 3% of the total demand and could well reach 10% by 2035.
Residential & commercial heating and cooling: According to the IEA, electricity will overtake natural gas for space and water heating through new construction or retrofits as office buildings, retail spaces, and institutional facilities transition to electric HVAC. We expect these segments to grow at a rate of 1.1% annually (CAGR) to 2035, well above the 0.7% rate of the past decade.
Industrial electrification: US manufacturing is expanding – driven by tariffs and reshoring trends – and integrating AI-driven automation and robotics. We expect industrial electrification to grow 1.9% CAGR to 2035, well above the 0.6% historical average.
Transport: While US EV sales have disappointed, there are around 5 million EVs on US roadways today representing around 2% of the total passenger fleet. Even if the mix of new vehicle sales would remain flat (~9%), the number of EVs would still rise by ~15% CAGR to 2035 to 22 million. In 2035, EVs could represent close to 10% of the total demand.
Figure 2 – Main drivers of increased US power demand

After more than two decades of flat demand, total US energy demand is expected to rise to 5,324 TWh by 2035 (up 2.4% CAGR from the actual demand of 4,112 TWh in 2024). Data centers are expected to account for 432 TWh or 36% of new demand, followed by the electrification of industry (19%), transport (18%), residential (15%), and commercial buildings (12%).

A supply-demand mismatch is raising costs
After decades of flat consumption, the US grid is not prepared for this scale of growth. Coal retirements and slow permitting for renewables have constrained electricity supply.4 Power regulators warn that half the US is facing power supply shortfalls in the next decade.5
Distribution complicates things further. Over 30% of transmission lines and nearly half of distribution infrastructure are approaching end-of-life. Capacity prices in PJM markets have risen tenfold in four years, while electricity prices have grown at 4% annually, underscoring the stress between reliability and affordability.6 Over the past five years, electric bills across the US have increased 24%. 7

Policy tailwinds and regulatory shifts
The US policy environment is evolving to meet this surge. The 2025 Energy Emergency Order introduced fast-track permits and deregulation, particularly for gas-fired power plants and transmission upgrades. Simultaneously, the legacy incentives of the Inflation Reduction Act and the One Big Beautiful Bill Act continue to channel capital into renewables and grid resilience. The bipartisan consensus on grid reliability ensures a supportive backdrop for US energy infrastructure investment.
Addressing the supply gap
We anticipate that the US will add between 500 GW and 600 GW of new capacity by 2035, with renewables accounting for approximately 60% to 70% of these additions. Natural gas will remain the backbone of reliability. Despite political scrutiny and the One Big Beautiful Bill, renewables are still expected to outpace new gas capacity. Supported by the current US administration, in the interim, coal plants may see extensions and utilities are already actively planning new gas generation projects. Nuclear power is also gaining popularity but high-cost and long-construction times mean it’s not a viable near-term solution.8
Despite political scrutiny and the One Big Beautiful Bill, renewables are still expected to outpace new gas capacity
According to the International Energy Agency (IEA), the US energy mix by 2040 could be made of 900 GW of solar, 600 GW of wind, 450 GW of natural gas, 250 GW of battery storage, 100 GW coal and nuclear.9 This mix highlights the need for ‘always-available’ dispatchable power to complement intermittent renewable energy sources.

Grid modernization: A public/private effort
As load growth accelerates, legacy power networks will come under increasing strain. The Department of Energy stressed that the US will need to build as much new transmission capacity in the next 10 years as it did over the past 60. By 2050, power networks will need to be at least two to three times larger to keep up with electrification trends, data center expansion and the clean energy transition.
The buildout means grid spending is expected to exceed USD 100 billion annually by the end of the decade, with grid infrastructure, smart grid components, as well as end-use equipment suppliers expected to benefit.
Grid infrastructure – transmission towers, high-voltage cables, step-down transformers, switchgear
Smart grid components – hard and software equipment including sensors, chips and analytics
End-use equipment – EV components, charging networks, building electrification gear
As the climate transition and the push to decarbonize accelerate, utilities are designing plans to integrate dispatchable and renewable assets. Companies active in wind and solar value chains, battery and storage players as well as other power ‘enablers’ will undoubtedly benefit from these moves to secure power generation.
Meanwhile, Big Tech hyperscalers such as Amazon, Google, and Microsoft are increasingly acting as power producers – investing in on-site gas turbines and modular nuclear pilots as well as negotiating exclusive power-purchasing agreements (PPAs) with local utilities. Combined with public sector expansion, private efforts will further boost investments in smart energy generation and transmission infrastructure.
Conclusion
The global economy is shifting from hydrocarbons to electrons. That’s a multi-decade evolution underpinned by AI, EVs and electrification, industrial policy, and an aging and ill-equipped grid. It is nothing short of a power demand supercycle. In this new era, access to power becomes the new competitive advantage, and strategies aligned with the buildout of generation, storage, and grid capacity stand at the forefront of a compelling investment cycle.
