Nova Scotia Power burned through another $2.2 million from ratepayers late last year at its ill-fated refurbishment of the Tusket hydro dam near Yarmouth, N.S. The disclosure of contingency spending during the last three months of 2021 was ordered by the Nova Scotia Utility and Review Board after the company told the regulator on Jan. 31 it was halting work yet again due to water seepage. The company filed its contingency spending to meet a Feb. 23 deadline imposed by the regulator.
