Alliance Technical Group Acquired by Blackstone Energy

Blackstone Energy Transition Partners and other Blackstone funds have acquired Alliance Technical Group (ATG), a provider of environmental testing, monitoring, and compliance services. ATG was founded in 2000 and is headquartered in Alabama.

ATG has grown into one of the largest full-service environmental compliance providers in North America, with more than 2,200 employees across 60-plus offices and labs in the U.S. and Canada. Its services include source and lab testing, continuous emission monitoring systems (CEMS), and leak detection and repair.

Blackstone said the acquisition supports its strategy to back businesses positioned to benefit from growing electricity demand and the broader energy transition.
