Power went off in the courthouse about 11:45 a.m., prompting an emergency generator to kick on that provided minimal lighting in the building. URBANA — Power was off in a section of downtown Urbana today, including the Champaign County Courthouse, and Ameren Illinois crews were looking to find the source of the outage. There were 51 customers county-wide still without power as of about 12:50 p.m., according to Ameren spokesman Tucker Kennedy.
