Limits of off-grid power and backup generation

New analysis from Wood Mackenzie shows that 220 gigawatts of additional power demand from data centers is in the pipeline in the US, and 183 GW of that is already backed by firm commercial commitments. That is a huge amount to add in just a few years: it’s equal to about 22% of US peak demand in 2025. The big question is whether the US electricity industry going to be able to meet that additional demand. And if so, how?

On the second day of ACORE’s 2026 Policy Forum in Washington, host Ed Crooks talks to industry leaders and experts about the answers to those questions. First he talks to Wood Mackenzie’s Anna Shpitsberg, who is global head of power and renewables research. She breaks down the numbers on electricity demand from new data centers, and discusses some of the implications for the industry.

Next up is someone whose role is right at the heart of the data center boom. Arthur Haubenstock is senior counsel at Equinix, which is one of the world’s largest developers, owners and operators. He talks about what data centers actually need in terms of electricity supply, and gives his perspective on some of the controversies currently raging around the industry.

A key issue for him is how data center developers can benefit local communities by cutting their electricity bills and strengthening the stability of the grid. He talks about the reality behind popular ideas such as BYOP (bring your own power) and BYONCE (bring your own new clean energy). And he explains why data centers often cannot be flexible loads on the grid, the constraints on backup generation, and why power grids matter.

Ray Long, President and CEO of ACORE, then joins the show to talk about his key takeaways from the event. He says the AI-driven data center boom is creating great opportunities for all kinds of energy, including renewables and other low-carbon technologies. But progress is being slowed by three critical challenges: permitting delays, trade policy uncertainty, and regulatory bottlenecks.

With electricity demand surging, he says, tackling those policy barriers is essential. Governments and the power industry need to find ways to stop electricity bills soaring and the grid becoming unstable, while enabling the infrastructure buildout required for AI. 

Finally, Ed talks to three entrepreneurs who are leading startup companies that aim to build the energy industry of the future. Kimberly Johnston of NextGen Energy, Saxon Metzger of Polaris Ecosystems, and Ebony Seymour of Ellement Group, explain the problems in energy that they are taking on, and talk about what they need to accelerate their growth.

This episode is brought to you by ACORE, the nonpartisan nonprofit organization uniquely operating at the intersection of energy affordability, reliability, and clean energy deployment. ACORE is focused on strengthening the electric grid and driving clean energy investment that delivers for the American people.  

ACORE’s membership includes industry leaders across the clean energy economy. Nearly 80% of the booming utility-scale domestic clean energy growth was financed, developed, owned, equipped, or contracted by ACORE members.
