Watts up, 2030?

Demand for electricity around the world is soaring. In developed countries, demand is projected to more than triple between 2000 and 2030. This surge brings with it demand for extending the life of transformers, explains Johan Grövik, Marketing Manager for Nynas transformer oils.

The increase in global demand – a result of an estimated 8 billion people on the planet – will require an enormous investment in infrastructure. How energy is produced will also shift dramatically. Of the $7.7 trillion to be invested in global electricity generation over the next 15 years, 60 percent will go to renewable technologies like wind, solar and hydroelectric power.

As the world's electricity needs grow, there will be an increased focus on prolonging the life of transformers as well as on providing cost-efficient, sustainable solutions. At Nynas we have worked with our customers for over 50 years to optimise the performance of their transformers, and we continue to invest in new research and solutions.

One area we have researched and worked on has been the heat transfer properties of transformer oils. Our experts found that naphthenic oils offer advantages because of their viscosity properties.

With a growing focus on sustainability, we are also happy to see that the industry is beginning to see mineral oil as an environmentally friendly option. Our oils will keep transformers running for 40 to 50 years – well beyond 2030 – before they have to be re-refined and used again.
