Top Energy is looking forward to a successful future!

Top Energy is owned by the Top Energy Consumer Trust, on behalf of 31,000 power consumers connected to our network. Our assets are worth in excess of $300 million and we employ over three hundred people. We’re involved in electricity generation, lines distribution, electrical contracting and customer contact centres and we have operations in the Far North, Auckland and Fiji.

Ngawha Geothermal Power Station

Our Geothermal Power Station was commissioned in 1998 and currently produces around 70% of all electricity used in the Far North. The Ngawha Geothermal Field is the only high temperature geothermal resource in New Zealand outside the Taupo Volcanic Zone. The reservoir is about 600 metres below ground and is thought to be between 20 and 40 square kilometers in area, with temperatures reaching temperatures up to 230 degrees Celcius. Using leading edge technology, geothermal fluids are brought to the surface and passed through a heat exchanger where energy (heat) is transferred to a working fluid (pentane). The pentane then boils creating a high-pressure vapour which drives the turbines, turning the generator. Ngawha has tripled its staff numbers in the last 3 years.

Top Energy Network

Our lines network comprises about 4,500 kilometres of powerlines and cables. We cover about 6,822 square kilometers of the northern most area of New Zealand encompassing some fairly rugged, sparsely populated terrain. Our lines, especially those in remote areas, are constantly under threat by fast growing vegetation which blows onto lines causing power outages. As a result we are investing 9 million dollars in a vegetation control program over the next three years. We currently employ 20 people in this area and intend to grow team numbers to 28. We’re also investing 4.4 million in equipment that isolates faults and a further 2 million to reduce the effects of lightening strikes. As a result our network division is experiencing massive growth and we are recruiting for a large number of roles.

Contracting Services

Contracting operates from purpose built depots in Kaitaia and Puketona, in the Bay of Islands. We employ over 110 staff including qualified technicians, line engineers and electricians who provide the expertise to operate and maintain the network infrastructure. Contracting also provides a wide range of electrical reticulation services to external clients such as local authorities, infrastructure owners and developers subdividing their property

Our Vision
Our strategy is to increase electricity capacity to meet future growth on the network, improve reliability of supply for all Far North Power Consumers and provide an acceptable level of return on Top Energyï¿½s network assets.
