Four days after the President of NB Power claimed the Point Lepreau nuclear reactor did not miss a deadline to be back in service on Oct. 1, the utility filed evidence with the Energy and Utilities Board saying it was supposed to be working by that date.

In August, 2012, the EUB ordered NB Power to provide detailed calculations on the expected lifespan of a refurbished Point Lepreau Nuclear Generating Station and on Friday the utility complied, submitting a chart showing the plant was to be "available" to produce power to the province from Oct. 1, 2012, all the way to May 22, 2040.

Last Monday, Gaetan Thomas, the president and chief executive officer of NB Power, denied Oct. 1 was a scheduled restart date for the nuclear reactor, the fifth it would have missed since overshooting its original completion date three years ago.

NB Power's lawyer had told the EUB in March that Oct. 1 was the target date for a restart but Thomas said it had been selected by accountants for planning purposes and had never been a real target.

"They had to pick a date," Thomas said on Monday.

"They picked a date of Oct. 1 for financial purposes only."

But on Friday, the utility detailed plans showing Point Lepreau was scheduled to produce 4,063 hours of "effective full power" by the end of the current fiscal year on March 31, 2013. According to the filing, that involved it starting Oct. 1 and operating at 93 per cent capacity for six straight months.

NB Power spokesperson Kathleen Duguay says although the new evidence does list Point Lepreau's starting date as Oct. 1, it was done only to match dates used in earlier evidence submitted to the EUB.

"We want to remain consistent with the evidence previously filed," she said.
