Asked why were the Tuem and Verna sub-stations scrapped, he said, the government does not need any wasteful expenditure as of now. “We have a high power sub-station in Cuncolim from 2010, which was taken up at a cost of Rs 86 cr, but till date only 30 per cent of the capacity is being used. We will shift a transformer from there to Tivim, which will give us additional power in North Goa,” he said.
