Champions of sustainability
This year’s conference follows the Transformers Magazine’s Industry Navigator research, conducted last year, which also covered some aspects of sustainability. The research results have revealed that across the value chain and among different applications, there are significant differences in views on sustainability and related priorities.
This is indeed what we can see in the current practice – data related to sustainability are more frequently required in tenders and purchasing documentation, where different companies require different data and use different formats. This, unfortunately, significantly increases the workload and amount of documentation, undermining the very purpose of the initiative.
Therefore, there is a strong need to consider and discuss different views and priorities as well as to coordinate all activities with the objective of harmonizing the requirements and documentation to the greatest possible extent.
Many companies are considering projects related to sustainability; many will do this soon, therefore, now is the time to get together and unite efforts in making some order in this area to get better results.
In this conference we aimed to present, discuss, and clarify practical aspects of today’s practices, such as:
Following the conference, research focused on key questions related to sustainability was conducted, which provided us with actionable results. You can download the report with all data here.

SGB SMIT Group
The energy sector has a major role in the energy transition towards cleaner energy. With the increase of 6 % in 2021, which stands for 36.3 billion tonnes of global CO2 emissions related to energy, our sector needs to take responsibility (https://www.iea.org/news/global-co2-emissions-rebounded-to-their-highest-level-in-history-in-2021). Our transformers are an important asset within this ecosystem, they need to fit in future demands. Within our value chain, we need to define how to make the transition towards green transformers, and understand what green transformers are, how to measure circularity and make it more concrete, what is required. We have calculated our impact and we have insight into supplier capabilities and can already offer more sustainable products or take back assets. What is important to understand is what investments everybody is prepared to make in order to make this journey happen. “Transforming together the future of energy.”

Transformers are highly material-intensive and energy efficient devices with a long operational life-time. Taking a life-cycle perspective on their environmental impact is crucial to optimize the design of new transformers that contribute to advancing a more sustainable energy value chain and a sustainable energy future for all.
In this session, we are sharing insights from our life-cycle impact assessment tool by discussing the impact of different transformer design options on their environmental and economic (TCO) performance. We discuss the implications of these results on future design choices and emphasize the need for factoring the value of future carbon costs associated with operational losses for choosing an environmentally as well as economically optimized design.

The presentation will show the global increase in electricity demand estimated for 2030 and 2050 due to a massive electrification of end-users and rapidly growth of electric vehicles. By 2050, solar PV and wind will be the main supply in the global electricity matrix. Important to review planned actions to reduce CO2 emissions in the electricity sector like accelerate decarbonization in the electricity generation as well as to prioritize improvements in the energy efficient. Transformers plays a vital role in the electricity sector and its industry can contribute with sustainable strategies adopting methods of energy efficiency (reducing losses) and selecting environmentally friendly materials, more specifically for the insulating liquid. In the last two decades, the use of natural ester insulating liquids has increased globally due to the properties like environmentally friendly (biodegradable and non-toxic) and safer (with a higher fire point). And now, when sustainability is pushing new actions in the electrical sector, another property of natural ester is in highlight: carbon neutral. A proposal case to mitigate CO2 emissions using FR3 natural ester in the power transformers int the electrical power transmission sector in Brazil will be analyzed.

Increasing urbanisation, efficient land use, effective asset management, capability for renewable generation & battery storage integration, changing load profiles, regulatory changes, sustainability, financial prudence, and, critically, reducing human and environmental risk, are all factors that influence utilities companies and substation designer’s decisions. These factors are now converging in many cases, especially in more populated locations, to make the use of mineral oil in substations expensive in terms of mitigation or even untenable given that alternatives are available. Ester liquids have become an established alternative that enable cost and carbon savings in substation designs due to being less flammable and readily biodegradable, while also delivering operational flexibility and potential to extend asset life. This presentation will set out a case for the adoption of esters as the standard dielectric liquid for substations.

Our customers (transformer makers) and their customers (utilities, etc.) have ambitious decarbonization targets – and sustainability is a key priority. Now it is time to walk the talk for all of us. How can we as an essential raw material supplier support this? How can we ourselves decarbonize our product and, by this, support the targets of our customers? tkES is truly committed to decarbonizing itself and, with this, supporting our customers and the electricity industry. We believe that CO2-reduced steel and grid assets are a must in a carbon-sensitive industry. With our product, we represent a base material for the energy transition and we continue to work on improving the quality (magnetic losses, noise, reliability). Energy transition and decarbonization go hand in hand, and CO2-reduced steel is the most efficient lever to decarbonize transformers. With this background, we aim to inform our customers and their customers about solutions for decarbonization, and initiate a discussion on these activities. Ultimately, we can only change (the electricity world to green) if we do it together and involve all stakeholders and regulations.

Constant increase in the greenhouse gas emissions leads to a greater interest of the customers, employees and shareholders in the environmental impact of their activities, products and services.
Carbon Footprint of a Product (CFP) is term closely related to the greenhouse gas emissions which is described within the standard ISO 14067:2018 Carbon footprint of products. The CFP is considered as a total of the greenhouse emissions generated during the life cycle of a product – from raw material acquisition or generation from natural resources to dispatch from the factory or final disposal, depending on the system boundaries.
In Končar D&ST, used functional unit was the product – oil immersed transformer, in different product variations. The Life Cycle Assessment scope used in CFP study was “cradle to grave” – it covers the CFP from the acquisition of the raw materials (“cradle”) up to end of life of the product (“grave”). The objectives of product life cycle calculations in Končar D&ST were to reduce the use of natural resources and emissions to the environment, as well as to improve social performance at different stages of the product life cycle.
According to the company’s sustainability strategy CFP has been recognized as an opportunity for transparent communication to interested parties about its carbon management.
In this way company could achieve greener products and processes, competitive advantage in the market and improved platform that will meet the needs of the changing business climate.

One of the generally accepted solutions extending the transformer’s life and avoiding inutile environment pollution by insulating oils is to provide adequate oil treatments. Today’s oil treatment market is overcrowded with numerous technologies, companies, and service providers. Due to increased sensitivity of new designs and materials in recent decades, selecting experienced, knowledgeable, and veteran companies is vital. The presentation will showcase some best available technologies by veteran and hi-tech companies dealing in advanced oil treatment systems . These technologies also make it possible to treat all insulating liquids available today on the market. Online monitors may provide the best-tailored recipe, both by saving time and energy, for becoming sustainable. It is probably the best practical methodology for preserving significant quantities of valuable mineral and vegetable resources, along with prolonging the transformer’s operational life.

Increasing prices for raw materials and for energy due to the political and environmental circumstances put this topic in the center of attention more than ever before. Accordingly, transformer manufacturers as well as system grid operators are keen on implementing their goals for being sustainable as fast and as significantly as possible.
While the transformer manufacturers are continuously developing new compact design, increase the efficiency and ensure a reliable operational safety and the grid operators expect less noise and losses, an extended lifetime and optimized thermal design with a green CO2 footprint.
Intelligent solutions for digitalization and automation could enhance the opportunities within the energy sector to achieve the required results. A CPU combined with an exclusive algorithm could help to operate the grid in a smarter way and support transformer manufacturers to optimize individual transformer design. Improving possibilities of the operator’s maintenance strategy might extend the lifetime of power transformers.
It is not only the transformer manufacturer or the system grid operator who have an influence to the green footprint, there are much more players in this game.
