What Mitsubishi Electric Power Products, Inc. does

Mitsubishi Electric Power Products, Inc. (MEPPI) is a wholly-owned U.S. subsidiary of Mitsubishi Electric Corporation, incorporated in 1985 as a 50/50 joint venture with Westinghouse Electric and rebranded under its current name in 1990. The company designs, manufactures, and services electrical power systems, rail transportation equipment, and large-scale LED video displays for the North American market from its Warrendale, Pennsylvania headquarters and ISO 9001:2015-certified North American manufacturing facilities.

MEPPI's core technology portfolio spans high-voltage and medium-voltage power infrastructure (Gas Insulated Switchgear from 72.5 kV to 800 kV, Air Insulated Switchgear, HV and MV circuit breakers, power transformers), power electronics (HVDC-Diamond voltage source converters, SVC-Diamond STATCOM, FACTS, PV inverters), battery energy storage systems, and the MELTAC nuclear instrumentation and control platform. Its Digital Solutions Division, anchored by the Smarter Grid Solutions subsidiary, distributes the Strata Grid DERMS software with patented approaches to DER optimization and forecasting. Rail transportation offerings include Communication-Based Train Control (CBTC), Train Control and Monitoring Systems, propulsion, HVAC, Solid State Interlocking, and wayside monitoring. The Diamond Vision division supplies large-scale LED video displays and Diamond Dot architectural lighting for sports venues, broadcasting, command-and-control centers, OOH advertising, retail, and spectaculars.

Revenue is generated through hardware sales (the largest stream), software licensing and implementation services for DERMS, professional services (engineering consulting and breaker maintenance), and turnkey substation engineering, procurement, and construction. The go-to-market model is consultative enterprise field sales with dedicated teams in Pittsburgh and New York, supplemented by participation in industry events such as IEEE T&D. Pricing is project-based and not publicly disclosed. Customer concentration spans electric utilities (Avangrid, Con Edison, UK Power Networks), transit authorities, marquee sports venues (AT&T Stadium, Yankee Stadium, Lumen Field, PNC Park), and OOH media operators (Marriott Marquis Times Square, Dundas Square Toronto).
