The building that houses the Wisconsin Housing and Economic Development (WHEDA) is closed Wednesday due to a fire that broke out overnight according to a release from WHEDA. Madison Fire Department said they were called to the Tommy Thompson Commerce Center around 1:06 a.m. for an activated alarm.

Fire officials said when firefighters arrived the fire was out. They say a high-voltage power supply to the building shorted and caused sparks to shower down on some plastic materials underneath. A small fire ignited, and the automatic sprinkler system in the room caught the fire early.

A representative from WHEDA says there is no power in the building, and it’s completely closed at this time. Power is not expected to be restored until Thursday. Employees have been told not to report to work until they are notified.

Fire officials say there’s limited fire damage to the room and a small amount of smoke damage in the area where the fire took place.

Wisconsin Economic Development Corporation (WEDC), Department of Financial Institutions (DFI), the Educational Approval Board, the Department of Veterans Affairs and the Department of Tourism also have offices located in the Tommy Thompson Commerce Center.
