Should the federal government prioritize hardening the domestic power grid against potential physical or cyber attacks?

At the 2026 Energy & Defense Summit, officials highlighted the military's current reliance on diesel generators to meet critical power mandates. The summit emphasized the necessity of transitioning to distributed energy solutions to address systemic vulnerabilities in domestic power infrastructure.

Why it matters

The military relies on the civilian grid and vulnerable petroleum depots, making energy modernization a national security priority. Shifting toward independent power systems aims to reduce exposure to physical and cyber threats against stationary fuel supply lines.

Solar battery systems can increase operating resupply capability by more than two times compared to standard diesel fuel logistics. Military units currently manage energy loads through localized distribution, though they must meet a mandated 14-day off-grid survival standard.

The players

Atlantic Council

A nonpartisan think tank focused on international affairs and security policy that hosted the 2026 Energy & Defense Summit.

Department of Defense

The executive branch department responsible for coordinating military operations and maintaining the resilience of national security infrastructure.

The details

Military resilience currently depends on diesel-burning generators, which require constant fuel resupply and leave storage depots exposed as high-value targets. By integrating solar battery arrays, facilities can generate and store power locally, shifting away from long-distance petroleum logistics. Commanders track energy loads to maintain critical distribution, a process currently tested through 50 annual blackstart exercises to ensure the grid can recover from total failure.

The Tech Race

The push to modernize energy systems follows a long-standing mandate to secure military operations against grid failure. This effort aligns with the Department of Defense's 14-day off-grid survival standard, which currently forces a transition away from vulnerable, centralized diesel dependence.

Military installations across the United States will prioritize shifting from diesel-only power to integrated solar battery systems to maintain operational continuity. This change focuses on hardening critical infrastructure against cyber and physical threats to domestic energy supply chains.

The takeaway

The move toward distributed energy aims to eliminate reliance on vulnerable, single-source fuel supply lines for base operations. Watch for updates to the annual schedule of 50 blackstart exercises, which serve as the primary metric for verifying that these new power systems meet resilience standards.
