The proposal involves an increase of four per cent each year for the next three years. The original plan involved average increases of nine per cent in 2012, four per cent in 2013 and two per cent in 2014.
The trade-off is the company will delay payment of millions of dollars worth of coal and other fuel for three years.
"The plan takes into account that we will have the money to pay that in rates when we get to that point, not all at once, much as you might pay a high balance on credit card," said Rene Gallant, General Manager and Regulatory Counsel for the utility.
That means paying interest later on fuel burned to make electricity now.
The plan has been proposed to keep prices predictable, but Gallant warns that rates could jump if a large industrial customer shuts down or if big storms or hurricanes wrack up repair costs.
"A storm like a hurricane can be in the millions of dollars," he said, "both because of the restoration costs and then making sure people are back on line as soon as possible."
If approved by the Nova Scotia Utility and Review Board, new general electricity rates would take effect January 1, 2012.
