Short power cuts as upgrades take over

Nelson central city homes and businesses can expect short power cuts as Nelson Electricity switches power over to its new substation at Haven Rd.

This will happen progressively from Monday and is a case of short term pain for long term gain as the project is designed to cater for future demand and offer improved security of supply.

The company, which distributes electricity to 9100 electricity consumers in the central Nelson city area, has been working over the past year on two infrastructure projects costing $11 million.

It is now completing replacement of its outdoor main zone substation at Haven Rd, built in 1959, with a modern zone substation, with all equipment housed indoors.

A new 33,000-volt underground feeder cable from Transpower's Stoke substation at Marsden Valley has also been laid to the new zone substation.

Mr Goodall said the new substation would increase capacity from 35MVA up to 48MVA and was designed to minimise electricity disruption in the event of equipment failure. The new underground cable increased the number of feeders from Transpower's Stoke substation to four.

It would provide diversified supply options to Nelson Electricity while increasing available capacity in the foreseeable future.

The changeover will see electricity cut to each of the homes and businesses the substation services - from the beginning of Atawhai to Boundary Rd in Bishopdale for one to two minutes as the power is transferred to the new substation.

This will occur over the next four weeks in a staged approach and start on Monday for the Port and Port Hills area. The outages will be at about 7am. Mr Goodall said there was no perfect time and it was a compromise as it was outside of business hours, and at the same time, would have minimal impact on residential consumers.
