NB Power extends deadline for public input on Mactaquac future
Public sessions scheduled for Fredericton, Woodstock and Mactaquac in May
NB Power has scheduled public information sessions for May on the future of the Mactaquac dam and generating station.
The Crown utility has also extended the deadline for public input until the end of May and released a new discussion paper on its website.
The Mactaquac hydro dam, operating on the St. John river west of Fredericton since 1968, provides 12 per cent of the province's electricity, according to the document.

But due to an unanticipated chemical reaction in its concrete structures, the generating station's life expectancy is expected to end in 2030.
According to the utility, any of the options will cost a minimum of $2 billion, an expense that will be picked up by rate payers and replacing the power station could raise the cost to as much as $5 billion.
If the power station is not replaced, another source of renewable energy would have to be found to help meet a legislated requirement that 40 per cent of the province's electricity sales come from renewables by 2020.
While not described as an option, the discussion paper notes NB Power continues to look for ways to repair the existing power station to extend its life beyond 2030.
A "partial insitu rebuild was determined to be worthy of evaluation," said the document. "Under this approach only some of the concrete around key mechanical components would be replaced. The remainder would be left in place."
There is no mention of a cost estimate or timeline for that scenario.
The three new public sessions were announced Thursday.
- May 17, Fredericton
- May 18, Mactaquac
- May 19, Woodstock
Times and exact locations for the sessions have not yet been announced.
