Projects

Work we're proud to put our name on.

Real jobs, real conditions — from utility-scale solar in Northern Michigan to heavy industrial power, downtown Detroit commercial build-outs, and school mechanical and HVAC controls.

Solar Farm Panel & Inverter Installation

Grassel Electric installed solar panel arrays and central inverters on a utility-scale solar farm in Northern Michigan — working through snow and sub-freezing temperatures to keep the project on schedule. Scope covered tracker row assembly, underground DC feeder trenching and terminations, and setting the inverter skids that tie the array to the grid.

Foundry Power & Controls Work

Industrial electrical work inside an abrasive steel making plant in Melvindale. Grassel Electric handled heavy switchgear and bus connections, control panel wiring, VFD installations, and power distribution for demanding melt-floor and production equipment — environments where downtime and failure aren't options.

Marriott Building Electrical Work

Electrical work at the Marriott building in downtown Detroit, right on the riverfront. Grassel Electric handled interior build-out wiring — running conduit and feeds through metal-stud framing, installing ceiling grid lighting and device boxes, and tying in building system controls including a variable frequency drive. High-rise, occupied-adjacent conditions where coordination and clean workmanship mattered as much as the code.

School Mechanical & HVAC Controls

Electrical work supporting mechanical-room upgrades at a school in Novi. Grassel Electric ran EMT conduit and junction boxes across cinder-block walls and HVAC ductwork, wired actuators and sensors on air-handling units, landed feeds into ABB breakers and VFD controls, and set a rooftop Eaton safety switch to power the new equipment. Coordinated work in an occupied-adjacent school environment, tied to the building's mechanical and building-automation systems.
