The Role of Transformer Stations in Renewable Energy Installations

Every renewable energy installation—whether a photovoltaic farm, a wind power plant, or a hybrid system—requires a precisely designed connection to the power grid. A critical component of this infrastructure is the medium/low voltage (MV/LV) transformer station, responsible for converting the generated voltage to a medium voltage level compatible with the infrastructure of the Distribution System Operator (DSO).

A properly selected and engineered station directly affects the safety, reliability, and profitability of the investment. At ELQ S.A., we design and manufacture prefabricated concrete transformer stations specifically intended for use in renewable energy projects, delivering solutions compliant with DSO requirements, legal standards, and investor expectations.

ELQ Transformer Stations – Tailored to the Demands of Renewable Energy Projects

Since 1976, we have specialized in the production of MV/LV transformer stations, continually expanding our technological capabilities and production capacity. Our stations are characterized by:

• monolithic reinforced concrete enclosures (foundation + walls + roof), ensuring structural durability and consistent technical performance,

• certified compliance with stringent European standards for quality and safety,

• integrated oil containment basins, protecting the environment from potential transformer oil leakage,

• lightweight thin-wall concrete construction, facilitating transport and installation even in challenging terrain,

• gravity-based ventilation systems, eliminating the need for noisy and energy-consuming forced air solutions.

Main Types and Configurations of ELQ Transformer Stations

ELQ transformer stations are available in various configurations and capacities—ranging from 250 kVA to 13.6 MVA—and are tailored to three core market segments:

• Renewable Energy Stations – designed for PV farms and wind power applications, featuring MV, LV, and transformer compartments integrated within a single enclosure,

• Industrial/Commercial Stations – engineered for manufacturing plants, logistics centers, and public infrastructure,

• Distribution Stations – built according to the specifications of individual DSOs.

Our stations are installed either on cable basements or foundation supports, with flexible cable routing and multi-directional output options. Thanks to a wide variety of roof types, façade finishes, and enclosure designs, each station can be adapted to specific architectural and environmental requirements.

Proven Experience and High Standards

We manage each project end-to-end—from technical consultation and operator approvals, through detailed design and prefabrication, to on-site installation, testing, and commissioning.

Our transformer stations are successfully deployed in hundreds of renewable energy installations across Poland and Europe. With a high degree of standardization and factory-controlled prefabrication, we ensure lead times of just 6 to 9 weeks, while maintaining full flexibility and a customer-centric approach.
