Bomb Threat Note Found in Porta-Potty Shuts Down Plant Yates, Highway 16

A handwritten note claiming an explosive device was hidden inside a portable toilet at Plant Yates sent hundreds of construction workers streaming out of the sprawling Georgia Power site in Coweta County on Monday, prompting a full evacuation and a temporary shutdown of a major nearby highway. The threat was reported at the plant's address on Dyer Road, setting off an immediate response from local emergency crews and law enforcement.

Georgia Power confirmed the handwritten note alleged a bomb was planted inside a portable toilet at the active construction site, according to a statement reported by FOX 5 Atlanta. The discovery triggered a site-wide evacuation as crews raced to clear the area. Atlanta News First reported that plant employees were being evacuated, per the Coweta County Emergency Management Agency, as authorities began investigating the threat and asked the public to avoid the area.

In response, the Coweta County Sheriff's Office and Emergency Management Agency temporarily shut down State Route/Highway 16 near the plant while responders swept the area, per the same FOX 5 Atlanta report. The closure affected a major traffic corridor running alongside the roughly 2,400-acre facility, which sits along the Chattahoochee River about eight miles northwest of Newnan.

Why So Many Workers Were on Site

The scale of the evacuation reflects just how much activity is currently underway at the aging plant. Plant Yates, which first opened in 1950 as one of Georgia Power's oldest facilities, historically ran seven coal-fired steam units before five were retired in 2015, with the remaining two converted to natural gas generating 700 megawatts, according to the utility's own environmental filings.

Today the site looks more like a construction zone than a legacy power plant. Georgia Power is in the midst of building three new simple-cycle natural gas combustion turbines, Units 8, 9 and 10, expected to add roughly 1,300 to 1,400 megawatts of capacity by 2027, a project approved under the Georgia Public Service Commission's 2023 Integrated Resource Plan Update. That buildout has added about 600 temporary construction workers to a site that otherwise employs around 75 permanent operational staff, explaining the large crowd that had to be moved out when the threat surfaced.

Potential Felony Exposure for Whoever Wrote the Note

Georgia law treats threats against critical infrastructure with particular severity. Transmitting a false bomb threat targeting facilities like a power plant is a felony under Official Code of Georgia Annotated § 16-10-28, carrying a punishment of five to ten years in prison, fines up to $100,000, and mandatory restitution to cover emergency response costs. State lawmakers further toughened penalties for false emergency reports through Senate Bill 421 in 2024, underscoring how seriously prosecutors are likely to pursue whoever is responsible for the note once identified.

A Site Already Under Scrutiny

Monday's threat lands amid heightened attention on energy infrastructure across Coweta County. Just four months earlier, deputies arrested four people following a break-in and equipment theft at a local Georgia Power facility, a case Hoodline covered in its report on the Coweta break-in arrests. Investigators at the time noted the stolen equipment's specialized nature raised questions about who might want it and why.

The plant also sits at the center of the region's data center boom. In April, county commissioners approved rezoning 829 acres directly adjacent to Plant Yates for Project Sail, a multi-building data center campus designed to tap directly into the plant's transmission lines, as detailed in Hoodline's coverage of the Project Sail rezoning. That approval came as Coweta and Fayette county residents have separately pushed back against transmission line expansion tied to another proposed data center near Walt Sanders Road.

The broader pressure driving all of this construction traces back to state regulators. In December 2025, the Georgia Public Service Commission approved a $16.3 billion utility plan authorizing Georgia Power to build or procure nearly 10,000 megawatts of new capacity statewide, driven largely by commercial data center demand, according to the Atlanta Journal-Constitution. Regulators rejected petitions from environmental groups seeking to reconsider that buildout earlier this year. Federal officials, meanwhile, have separately urged utility operators and local law enforcement nationwide to maintain heightened physical security given rising trespass, theft and threat incidents against power grid infrastructure.

No further details on the investigation's progress, the identity of any suspect, or when the plant and highway fully reopened were available at the time of this report.
