PROJECT ANNOUNCEMENT: Battery Energy Storage System (BESS)

The Medical Center Company of Cleveland (MCCo), under a general project management agreement with Ullman Electric & Technologies will introduce Northeast Ohio to the first Tesla Megapack installation of its kind in the area as part of the MCCo Campus.

MCCo and Ullman Electric broke ground together on this ambitious project on Thursday, July 31, 2025 at 10:00 AM. The final day of the month of American independence was specifically chosen for groundbreaking as a nod to MCCo’s commitment to using American Made (domestic) content in this MicroGrid Project. Representatives from the companies involved each donned a shovel to break ground near the MCCo facilities located at 11626 Mayfield Rd., Cleveland, OH 44106.

Megapacks, which are specifically designed for large-scale energy storage applications will be used to support the efforts of MCCo in bringing affordable energy to their clients in the University Circle area of the City of Cleveland, Ohio. The utility-scale battery provides trustworthy energy storage for grid resilience through frequency regulation and load shedding. The packs are considered sustainable, scalable, and environmentally responsible.
