Large Hospital, Athens, GA
St. Mary’s Hospital, located in Athens, Georgia, is a member of the Catholic Health East/Trinity Health System and consistently ranks among the top ten hospitals in the state.

Quality and Reliability in Efficient Electricity Usage
St. Mary’s Hospital – Athens, Georgia
As a leading healthcare provider in Northeast Georgia, the hospital was named Large Hospital of the Year in 2010 by the Georgia Alliance of Community Hospitals, and in 2011, it received the Circle of Life Award Citation of Honor from the American Hospital Association.
Challenge and Solution
In an effort to reduce operating expenses, St. Mary’s partnered with European Power Management Systems, LLC to optimize its electricity consumption. The customized energy efficiency project resulted in an average 15% reduction in total electric bills.
Beyond the cost savings, the hospital can now monitor energy usage in real time, identify unnecessary electrical loads, and implement a dynamic approach to energy conservation policies.
Technology and Innovation
The solution is powered by Terawatt’s next-generation Intelligent Demand Response (iDR) technology, which offers fully automated 24/7 demand optimization through a proprietary load management algorithm.
Terawatt’s Synapse platform manages the planning, implementation, monitoring, and optimization of the hospital’s private electrical network. It is designed to dynamically adjust energy usage patterns, reduce waste, and improve efficiency by interfacing with selected electrical equipment, fine-tuning performance based on actual operational needs.
The customized load profile is designed using an adapted simultaneity coefficient, helping shape the power demand curve and reducing total energy consumption, resulting in significant kWh savings.
Key Benefits
- Energy profile aligned with operational needs
- Lower electricity costs adapted to hospital requirements
- Year-round, permanent iDR optimization
- Remote access and real-time monitoring
- Live tracking of energy usage and carbon emissions
- Detailed reporting with measured and verified results
- Reliable and scalable energy conservation solution
Sustainability Impact
The energy savings achieved by the project are equivalent to:
Saving approximately 187,496 gallons of gasoline
Reducing 1,656 tons of CO₂ emissions
Planting 368 acres of trees
Removing over 304 cars from the road
