About
This year’s Transformers Magazine Industry Navigator conference entitled ‘Sustainability – outlook for the transformer industry‘ was held on 20 – 21 October 2022, in hybrid participation (online – Transformers Academy, physical – Zagreb, Croatia; Hotel Antunović, Zagrebačka avenija 100a).
This is an industry-wide event, where all parties had a chance to present their views on the subject and discuss the matter with other stakeholders. The objective was to identify the best approaches for improving sustainability in the industry.
The aim of the Navigator 2024 conference is…
Motivation
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.
Content
In this conference we aimed to present, discuss, and clarify practical aspects of today’s practices, such as:
Options for improving sustainability (circular economy, low losses, CO2 footprint, etc.);
Measures for practical use (which data best reflect improvements?);
An overview throughout the value chain (e.g. do we need to apply the same requirements for the transformer as for its minor components?);
Impacts on transformer specifications;
Impacts on the supply chain, etc.
The research
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.

Marlies van Tilburg, Sustainability Manager
ABSTRACT
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.”

ABSTRACT
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.

Roberto Ignacio da Silva, Technical Services Manager for Dielectric Fluids
ABSTRACT:
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.

Marika Rangstedt, Manager Sustainable Development
ABSTRACT
In recent years alternative insulating liquids have been a topic of much discussion. Traditional naphthenic mineral insulating oils still offer many advantages but other options such as re-refined mineral oils and bio-based hydrocarbons can add additional value to the user. It is evident sustainability is becoming a key attribute when it comes to insulating liquid selection. In this presentation we will discuss two new alternative fluids and how these alternatives contribute to sustainability.

James Reid, Technical Manager
ABSTRACT:
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.
SPEAKER’S BIO:

Marcel Hilgers, Head of Customers, Markets & Technology
ABSTRACT
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.
SPEAKERS’S BIO:
Marcel believes in listening to his customers and creating solutions to serve their true needs. With over 20 year experience in global steel business, and thereof more than 10 years serving the transformer industry, he now works intensely on the green transformation of both, steel and transformers.
Marcel leads the sales, technical customer engineering and communications team at thyssenkrupp Electrical Steel – the European and Indian market leader in grain oriented electrical steel.
His key priority today is to inform the electricity industry about options to decarbonize the grid and to form alliances across raw material suppliers, transformer makers and electric utilities.
