The challenges facing municipal utilities and local authorities are growing: the expansion of renewable energies, increasing loads due to electromobility and heat pumps, and bottlenecks in the procurement of new transformers pose new challenges for grid operators every day. Anyone who wants to guarantee security of supply must operate existing plants longer and more reliably – and do so sustainably. A decisive factor here is the right insulating oil for the transformers. For municipal utilities in particular, EOS® Premium insulating oil, a recycled oil from Electrical Oil Services (EOS®), offers a sustainable and technically safe solution for operating plants reliably for longer.
Rising energy demand, ageing infrastructure and long lead times for new transformers are currently posing major challenges for municipal and regional utilities. The safe operation of existing plants is becoming a key factor for a stable energy supply – and requires sustainable, reliable solutions.

Challenges faced by municipal, regional and community utilities in transformer management
|
Beyond the technical and economic challenges, municipal utilities must not lose sight of their customers’ expectations. According to an analysis by PwC Germany, the future strategic direction of utilities is closely linked to the needs of their end customers – whether they are sustainability-focused, digitally oriented or regionally engaged. The decisive factor is to combine technical reliability with a clear value proposition and tangible customer benefits.
So how can municipal utilities continue to operate their existing transformers safely, efficiently and sustainably – even under these demanding conditions?
Supply security is not achieved solely through new facilities, but above all through the forward-looking use of existing resources. Regularly monitoring and maintaining transformers, knowing the quality of the insulating oils and relying on high-quality transformer oils are all important steps towards preventing failures and significantly extending the service life of your equipment.
This turns maintenance into a strategic measure – and operational reliability into a real competitive advantage:

Electrical Oil Services recommends EOS® Premium to turn short-term procurement into a strategic investment in supply security and cost-effectiveness. It is a recycled product that is precisely tailored to the above requirements.
EOS® Premium combines high technical performance with proven sustainability – and can thus become a crucial component in ensuring the supply security of municipal utilities.
1. Technically equivalent to new transformer oil – compliant with IEC 60296:2020
EOS® Premium meets the current requirements of IEC 60296:2020 for recycled mineral insulating oils and can be used in transformers without restriction as a substitute for new oil. The transformer oil is carefully analysed, processed and approved according to clearly defined quality parameters. Municipal utilities benefit from a product that is ready for immediate use and meets all relevant safety and operating standards.
2. EOS® Premium supports runtime extension in times of transformer shortages
In times when new transformers are scarce and expensive, it is crucial to keep existing equipment safe and reliable in operation. Electrical Oil Services supports municipal utilities with recycled EOS® Premium and maintenance work that extends the service life of existing transformers and increases their performance. This enables municipal utilities to fulfil their supply obligations even if new transformers are delayed in delivery.
3. Sustainable within a closed loop – the EOS® Closed Loop model
Electrical Oil Services' recycling concept is based on the closed loop principle: used insulating oils from transformers are first analysed for quality, then cleaned and processed into EOS® Premium insulating oil that is as good as new. This saves valuable resources and reduces CO₂ emissions by more than half compared to new oil.
4. EOS® Premium ensures cost efficiency across the transformer life cycle
Recycled transformer oil such as EOS® Premium not only reduces resource consumption, but also lowers the total cost of ownership of a transformer. The use of high-quality reprocessed insulating oil delays the need for expensive transformer replacements, while maintaining a high level of operational safety and electrical properties.
