Re­dun­dancy saved the day

Re­plac­ing burned Sun­ny­side trans­former will take more than a year

which is typ­i­cally bolted down to main tank, opened up. Once the fire started it al­most looked like open­ing a can with a can opener type thing.”

He as­sured his of­fice is work­ing with the NL Hy­dro en­gi­neer­ing depart­ment to pre­pare spec­i­fi­ca­tions for a new trans­former at Sun­ny­side. The power grid isn’t cur­rently af­fected by the loss of burned trans­former.

Mr. Moore said NL Hy­dro’s Plan B in the event of the sec­ond trans­former fail­ing would be to dis­con­nect one from a sta­tion in Buchans and in­stall it at Sun­ny­side – a process he said would take at least a week.

It took a less than a day to make the switch be­tween the two Sun­ny­side transforme­rs.

Mr. Moore said “Right now we don’t have any re­dun­dancy, be­cause it’s only one trans­former in ser­vice. So cus­tomers are in ser­vice and have se­cure sup­ply, but cer­tainly don’t have the backup sup­ply that they once had un­til we get the trans­former re­placed.”

The ten­der­ing process for a new trans­former typ­i­cally takes more than a year.

“We’ll do what­ever we can do to ex­pe­dite it and get that re­dun­dant sup­ply back to the cus­tomers.”

The en­vi­ron­men­tal clean up of the oil and residue from the smoke is still on­go­ing at Sun­ny­side, with in­ter­na­tional con­sult­ing com­pany Stan­tec con­tracted to over­see the work.

Mr. Moore said the work may go into the spring when the snow melts.

“That has to be cleaned up and treated as an oil spill, al­though our feel­ing is the ma­jor­ity of the oil went up in smoke ba­si­cally. Any soot or oil stains on the ground we’re clean­ing up as per reg­u­la­tions and Stan­tec is ba­si­cally en­gaged to make sure that hap­pens for us in con­sul­ta­tion with our en­vi­ron­men­tal depart­ment.”
