BLACK START POWER OUTAGE EXPECTED THIS WEEK AT FORT STEWART AND HUNTER ARMY AIRFIELD

The power will go out at Fort Stewart and Hunter Army Airfield at some point this week. However, while the exact hour is a surprise, this is a heavily communicated event.

These installations have entered the execution window for a full-scale Black Start exercise, with installation messaging confirming it will take place at some time during this week in April.

According to a February 2026 Community Information Exchange briefing at Fort Stewart, the exercise is designed to simulate a loss of commercial power while maintaining mission-critical operations. Since then, garrison leadership and Balfour Beatty Communities held a specific Housing Town Hall on March 5 to discuss mitigations for families in the Exceptional Family Member Program.

Residents have been told to prepare for disruption tied to a planned loss of power. When it happens, it will not come with a final alert, making preparation essential to minimize disruptions during the outage.

Fort Stewart Briefing Sets the April Black Start Window

The plan has been in place for months.

Installation leadership identified April as the execution window and confirmed that on-post housing falls within the affected area.

The exercise centers on operating without reliance on the civilian power grid while sustaining essential functions internally.

Hunter Army Airfield Signals Large-Scale Power Impact

A recent communication from Hunter Army Airfield describes a “large-scale” exercise expected to temporarily affect power across the installation.

Residents there are advised to prepare for disruptions that reach into daily life, like refrigeration, internet, and utility connectivity, as well as routines that are dependent on stable electricity.

A Year of Energy Resilience Exercises Has Led to This Week

This week follows a long-term buildup. Fort Stewart and Hunter Army Airfield have conducted energy resilience exercises over the past year, including controlled outages and coordinated response drills testing infrastructure under stress.

For example, Hunter Army Airfield conducted a specific two-hour blackout drill back in March 2025, and the installations have been running monthly Energy Resilience Drills specifically to train up for this massive April 2026 execution window.

The Army describes these exercises as part of a congressionally mandated requirement to ensure installations can operate during potential threats to power disruption or blackout scenarios. From here, the scale expands.

On-Post Housing Falls Within the Impact Area

The exercise includes residential areas. Installation briefings have advised residents to prepare for power loss that may affect food storage, medical needs, and work or school routines dependent on electricity. There is no indication these impacts will be isolated from the broader installation footprint.

While there will be no final countdown or confirmed start time on the day of execution, residents should remember this is a highly coordinated event. The command has strict protocols in place for medical and operational emergencies.

Black Start Exercises Expand Across Army Installations

Black Start exercises are part of a broader Army effort to strengthen installation resilience during potential power loss events.

Army guidance states these exercises test whether installations can sustain emergency response, security, and command functions without relying on external power sources.

Fort Stewart is among the largest installations to execute the Black Start exercise at this scale.

Critical Systems Continue While Daily Life Disrupts

When the power drops, not everything goes dark. Critical infrastructure transitions to backup systems, emergency operations continue, and command functions remain active. Everything outside of that—routine, convenience, and predictability—will be disrupted quickly. Power will be restored after the exercise concludes.

What matters is everything that happens before that moment, and it begins with individual and family preparation and readiness for whenever the exercise commences.

Sometime this week, in a controlled and planned test, Fort Stewart and Hunter Army Airfield will run that exercise in real time, under real conditions, with guaranteed lessons learned and after-action reports to follow.
