Industrialists are up in arms over a penalty imposed on them by the Uttarakhand power corporation limited(UPCL) after a gap of two years. The entrepreneurs are of the view that in case they were found violating the laid down norms or consuming power during restricted hours, the UPCL should have informed them then. Neither they were aware about the restricted power cut hours during peak hours, nor did the concerned department issue any guidelines in this regard. So there should not be any such penalty, they demanded.
