MacAllister Power Systems brought together power industry leaders, customers, and policy makers for meaningful conversations around the future of energy infrastructure last Tuesday at the University of Michigan. Discussions focused on load growth, grid capacity challenges, and the rapid deployment of data centers shaping today’s power landscape.

Along with great networking opportunities, attendees enjoyed an incredible venue, great food, and exclusive behind-the-scenes access to the Michigan Wolverines football locker rooms and time on the field at the legendary Michigan Stadium.

Thank you to everyone who attended and contributed to the conversations and partnerships that made this event a success. Planning for next year’s event is already underway, and we’re looking forward to building on this momentum.

If it isn't properly inspected and maintained, even a well-functioning generator may not perform when a power outage occurs. At MacAllister Power Systems, we offer two levels of ATS inspections designed to help identify potential issues early, reduce downtime, and extend the life of your power system.
