Modernization of 35–150 kV substations: how digitalization saves industrial assets
The condition of many Ukrainian substations 35/110/150 kV today remains difficult: a significant part of the equipment is physically and morally obsolete. In modern realities, this is no longer just a problem of “old iron”, but a real risk for the continuous operation of the enterprise, its financial stability and production safety.
One accident on a key element of the substation can lead to a stop of technological processes, expensive repairs, loss of time and significant indirect losses. That is why the modernization of the substation today is not only a technical update, but a management decision to protect the business.

What does the modern market require?
The energy and industrial market places three key requirements on substations:
Flexibility and manageability — remote monitoring and fast access to data in real time.
Energy efficiency — reducing technical losses and increasing the efficiency of electricity distribution.
Response speed — modern microprocessor protection capable of quickly localizing damage and minimizing the consequences of accidents.
5 signs that a substation already needs modernization
To objectively assess the condition of an energy facility, it is worth paying attention to several practical signs.
- The equipment is outdated and often fails
Constant breakdowns, a shortage of spare parts, complex or expensive repairs, lack of manufacturer support — all this indicates that the substation is operating at the limit of its resource.
- Protection and automation do not meet modern requirements
If outdated solutions are used and the search for the causes of outages takes a long time, this increases the risk of damage to expensive equipment and delaying emergency recovery.
- There is no complete control over the state of the substation
The lack of SCADA, remote monitoring, event logs and centralized dispatching means that personnel often react after a problem occurs, rather than preventing it.
- Any intervention is associated with the risk of downtime
When even a minor repair or replacement of a node threatens to stop production, this indicates low flexibility of the infrastructure and the absence of a phased upgrade strategy.
- The substation does not meet modern safety requirements
This concerns both technical and operational safety, as well as the protection of digital systems, access control and the readiness of personnel to work with new solutions.
ELAKS strategy: key stages of modernization
With over 30 years of experience, the ELAKS team understands the real state of the industry well and implements a comprehensive approach to the modernization of 35–150 kV substations for customers.
1. In-depth audit and design
We start with a comprehensive inspection of the facility to identify bottlenecks, technical risks and growth points. We develop solutions that allow you to integrate new equipment into the existing architecture with minimal downtime.
2. Modern relay protection and automation systems
We implement modern relay protection systems that provide high selectivity, fast damage detection and more accurate fault localization. Self-diagnostics, oscillography and event analysis functions give staff more transparency and control.
3. Digital transition (Smart Grid) and dispatching
We integrate SCADA, digital protection terminals and other solutions from leading manufacturers, including Siemens, ABB, Schneider Electric. This allows you to receive up-to-date information about the network status in real time and increase the manageability of the facility.
4. Cybersecurity and information security
A digital substation should not only be modern, but also secure. That is why we provide solutions that help reduce the risks of unauthorized access to critical infrastructure.
5. Staff training and service support
Our approach is not limited to supply and installation. We provide staff training, commissioning and subsequent technical support so that the modernization really works.
Conclusion
Modernization of 35–150 kV substations today is not a cost for the sake of updating, but an investment in the stability, safety and manageability of the power facility. The longer the modernization is postponed, the higher the risks of accidents, downtime and unforeseen costs.
For business, this means one thing: modernization is a way not only to solve current problems, but also to create a basis for further development of the enterprise.
