(Richmond, IN)--What was described by local officials as a transformer and substation explosion knocked out power to much of Richmond Wednesday morning.  It happened at just after midnight.  Residents on Richmond’s south side reported hearing – and in some cases, feeling – the explosion, which left most of Richmond’s south side in the dark.  RP&L Wednesday morning was still assessing what happened, but they were able to get power restored to most homes in less than two hours.
