Powerstar’s latest international voltage optimization case study highlights a significant electrical consumption saving for Mount St. Mary’s University, located in Emmitsburg, Maryland.

Established in 1808, Mount St. Mary’s achieved university status in 2004, boasting 1 million square feet under roof across a 1,400-acre campus. Over the years, the university has grown to facilitate over 2,400 students and more than 1,000 staff. This, combined with the large variety of onsite electrical equipment required to provide each student with an outstanding educational environment, means that electrical consumption for the university is high, and continues to grow as student and staff numbers increase.


As a not-for-profit institution, with a student-centric focus and academic excellence at the core of its values, Mount St. Mary’s was looking for ways to make the most of its funds to allow maximum investment into its core objectives of academic excellence, and providing a transformative learning environment. Similarly, as an active part of the local community, the university takes environmental sustainability very seriously.

To achieve this, the university looked for ways to make savings on energy costs whilst reducing carbon emissions, and, after seeking advice from a trusted energy consultant at the university, research identified voltage optimization as a suitable technology to achieve this. Due to Powerstar’s patented and award-winning technology, as well as its customer-centric, customized approach, Powerstar was chosen to assist Mount St. Mary’s achieve these goals.


After a thorough analysis of the campus’ voltage profile, which was stable, but higher than required for onsite electrical equipment, the installation of a Powerstar LITE system was recommended.

The fixed low voltage optimization solution reduces the incoming voltage by a set amount over a pre-defined tap range, which corrects the overvoltage supplied by the local network to reduce electrical consumption. This, provides annual savings on electricity costs and minimizes carbon emissions, alongside longevity to the university’s electrical equipment from operating at a level closer to the design characteristics.

Utilizing approved partners within the region, Powerstar provided Mount St. Mary’s with a tailored, concept to completion solution designed to meet the unique requirements of the university, resulting in significant savings to its electrical consumption and costs. The savings generated by the can be reinvesting into the university’s core activities to continuously deliver on its student centric, academic excellence.

Major savings

Following the success of the initial installation, Mount St. Mary’s installed two additional Powerstar LITE systems with similar savings being achieved, and is also exploring additional electronic-dynamic Powerstar MAX voltage optimization solutions for the site.
