The facility, on the Norwich Research Park, features a 1000sq ft laboratory and will be home to the company's engineering team, which is relocating from Diss.
Steve Applegate, Stadium Power's commercial director, said: "This is a very exciting move for Stadium Power. We are already an established provider of customised power solutions, working with our customers to design, develop and innovate. However the RDC reflects the next stage in the execution of our strategy boosting our technology roadmap providing the power technologies of today and tomorrow, whilst ensuring that our development focus is tightly aligned to our customer's needs."
