Role of Transformer Insulation Fluid to various Power Stations in New Zealand
New Zealand’s Renewable Energy Revolution: Powering a Sustainable Future
New Zealand is making incredible strides in transforming its energy landscape. With 82% of the country’s electricity sourced from renewable resources, Aotearoa stands as a global leader in clean energy production. This impressive shift away from fossil fuels includes energy from hydro, geothermal, wind, and solar power—each playing a vital role in our journey toward sustainability. The remaining portion of our energy comes from non-renewable sources such as oil, natural gas, and a small amount of coal.
Hydropower: Harnessing the Power of Water
At the heart of New Zealand’s renewable energy production lies hydropower, the largest contributor to our energy supply. With more than 100 hydroelectric generating plants, Aotearoa boasts some of the most powerful stations in the world. Four major hydroelectric power stations in the South Island—Manapouri, Benmore, Clyde, and Roxburgh—account for a significant portion of the energy supply, while Maraetai on the North Island also plays an important role. Over 55% of New Zealand’s hydroelectric power comes from run-of-the-river schemes, which rely on natural river flows to generate electricity.
However, New Zealand’s heavy dependence on hydropower presents a challenge when weather conditions are less than ideal—especially during dry winters. This means that energy security can be at risk, but it also highlights the need for a diverse mix of renewable energy sources.
Geothermal Energy: A Hotbed of Innovation
New Zealand is one of the pioneers in geothermal energy development. With 17% of the country’s electricity generated from geothermal sources, it’s no surprise that Aotearoa is a global leader in this renewable resource. The majority of New Zealand’s geothermal energy comes from the Taupo Volcanic Zone and Ngawha, where over 62 years of geothermal operations have paved the way for clean, low-cost electricity generation.
In 2022, New Zealand’s geothermal power plants generated an impressive 8.06 TWh of electricity from 20 power stations located across eight high-temperature fields. With a strong focus on reducing carbon emissions, geothermal energy remains a key pillar of New Zealand’s energy transition towards a cleaner, greener future.
Wind Energy: Riding the Winds of Change
Thanks to its unique location across the prevailing westerly winds, New Zealand is blessed with some of the best wind resources on the planet. With 21 commercially operating wind farms and an installed capacity of 1.3 GW, wind energy contributes over 7.5% of the country’s annual electricity generation. This reliable, renewable resource is vital in ensuring that Aotearoa stays on track with its ambitious climate goals.
These wind farms not only provide clean power but also contribute significantly to the grid’s total generation capacity, helping us reduce our reliance on non-renewable energy sources.
Coal: A Declining Source of Power
While New Zealand has made impressive progress in renewable energy, coal still plays a role in our energy mix. The country burns approximately 2.5 million tonnes of coal each year, primarily for industrial uses such as electricity generation and steelmaking. The dairy industry is a major contributor, using coal to generate the large volumes of process heat required to convert milk into milk powder for export.
However, coal is increasingly being phased out of electricity generation, with Huntly Power Station, New Zealand’s only coal-fired plant, serving primarily as a backup when renewable energy supplies are low. As wind and solar farms continue to come online, the gap left by coal will be filled by cleaner, renewable alternatives.
The Role of Transformer Oil in New Zealand’s Energy Systems
To ensure the smooth operation of power generation systems—from hydroelectric dams to wind farms and geothermal stations—all energy sectors rely on power transformers and transformer oil. Transformer oil serves a critical function in cooling, insulating, lubricating, and quenching electrical arcs within transformers, helping to maintain a reliable energy supply.
This is where TSMB plays a crucial role. We provide high-quality transformer oils that keep New Zealand’s energy systems running smoothly and efficiently. Our extensive range of mineral oil and ester-based insulating fluids ensures that power transformers, hydroelectric dams, wind farms, and geothermal power stations can operate at their best.
At TSMB, we are committed to helping asset owners optimise costs, reduce maintenance downtime, and improve equipment reliability. As we continue to support New Zealand’s energy transition, we take pride in our role in helping decarbonise the power industry.
