Power prices in Nelson

As at May 2026, electricity in Nelson averaged 38.78c per kWh including GST. For a household using 8,000 kWh a year on a low-user plan, paying on time and taking any prompt-payment discount, with controlled hot water, that works out to roughly $3,102 a year. That is 7.8% below the national average of 42.04c, making Nelson the 39th most expensive of the 42 towns MBIE surveys.

Lines charges are the part of a power bill that changes most from town to town, because every area is served by a different network. In Nelson the lines component is 11.46c per kWh — 30% of the total, against 40% nationally. The remaining 27.32c covers energy, metering and retailer costs, which vary far less by location.

Nelson Electricity. Nelson sits in the Nelson (Nelson Electricity) network reporting region, and Nelson Electricity owns and maintains the poles and wires — so they are who you call in a power cut, not your power company. Their faults line is 0800 508 100. Your retailer is who you choose and who bills you; the lines company is fixed by where you live.

Yes. In February 2004 the Nelson average was 16.61c per kWh; by May 2026 it was 38.78c — a rise of 133% over 22 years. Over the last twelve months alone it rose 7.2%.

Possibly. The MBIE figure is an average of publicly advertised tariffs across Nelson, not a quote — what you pay depends on your usage, your meter and which company you are with. Switching retailer does not change the 11.46c lines component, but it does change the 27.32c that sits on top of it. Comparing the companies we work with is free and takes a couple of minutes.
