<h1>Panattoni BTS has completed construction of the ZREW Transformatory factory in Łódź. The PLN 115 million investment, delivered under the build-to-suit model, has been adapted for the production and testing of large-format power transformers. The facility was officially opened on November 3 this year. ZREW plans to employ around 200 people there, including engineers, technicians, and other specialists.</h1><blockquote>"The completion of the new factory marks an important stage in the development of ZREW Transformatory. The investment will allow us to double our production capacity and expand the parameters of the equipment we manufacture. The new plant is among the most advanced facilities of its kind in Europe, responds to the growing needs of the energy market, and creates conditions for further developing our technological competencies. Staying in Łódź holds particular significance for us. This is a city with which ZREW has been associated for nearly 70 years, offering experienced staff, technical infrastructure, and the potential to train future specialists," says Grzegorz Sołtysiak, President of the Management Board of ZREW Transformatory S.A.</blockquote><h2>A factory designed around the production process</h2>The project was developed in close cooperation between Panattoni BTS and ZREW, taking into account the specifics of production and the company's development plans. Delivering the facility required adapting the building's structure and technological infrastructure to the particular requirements of transformer manufacturing. Solutions enabling the safe movement of equipment weighing over 200 tons, as well as the execution of advanced assembly and testing processes, were of key importance.<blockquote>"Delivering the factory for ZREW Transformatory shows how essential it is to combine development expertise with a deep understanding of the client's industrial processes. In this project, standard construction solutions were not enough – the facility had to be designed around transformer production technology, the dimensions and weight of the units, and the requirements related to transport and testing. Together, we created infrastructure that meets ZREW's current needs and gives the company room to further scale its operations. Projects like this strengthen the potential of modern industry and demonstrate Panattoni BTS's role in developing advanced production investments," says Marek Foryński, Managing Director at Panattoni BTS.</blockquote><h2>Specialized equipment and technical solutions</h2>The facility is equipped with 16 overhead cranes with a combined lifting capacity of 360 tons, including units with a lifting capacity of 100 tons. External transport of the heaviest elements is supported by a dedicated gantry crane, capable of moving transformers weighing more than 200 tons. Inside the factory, an air-cushion transport system has also been implemented, facilitating the precise movement of heavy equipment and components.Among the specialized technological solutions are high-voltage testing chambers equipped with electromagnetic shielding systems, as well as a custom-built drying facility for transformer components. The building's structure accommodates high load-bearing requirements of up to 1,600 tons: the floor was designed to withstand loads of up to 210 tons, and the building has varying heights, reaching up to 20 meters. The investment includes a production hall as well as an office and social facilities section.JLL advisors supported ZREW Transformatory throughout the process, from market analysis to negotiations, helping align the investment's parameters with the company's long-term needs.<blockquote>"Transformers weighing 200 tons and high-voltage testing chambers leave no room for compromise. ZREW's new production facility shows that the BTS market in Central Poland has matured enough to support truly advanced industrial manufacturing. From an advisory perspective, this also represents a completely different scale of work: we started with the analysis of a standard warehouse and ended up with a project in which every stage – the carefully considered and precise choice of location, commercial negotiations, and ultimately a precise work schedule – had to be tailored to the client's highly specific technological requirements," adds Wiktor Lesiak, Senior Consultant in the Industrial department at JLL.</blockquote>The facility was built in accordance with sustainable development principles and will undergo BREEAM certification at the Excellent level. The investment is covered by public support within the Łódź Special Economic Zone.<h2>Central Poland attracts tenants</h2>Łódź, whose development was driven for decades by the textile industry, has undergone a significant economic transformation, becoming a hub for modern manufacturing, including electrical equipment, household appliances, and pharmaceuticals. The new ZREW factory fits into this industrial tradition of the city while also forming part of broader economic activity in Central Poland – according to JLL data, demand for industrial space reached 545,000 sqm, the third-highest result in the country. With a vacancy rate of 4.8%, below the national average, new supply is developing primarily in response to specific tenant needs. Of the 163,000 sqm of space currently under construction, only around 10% is being built speculatively, highlighting the predominance of investments secured by lease agreements, including build-to-suit projects tailored to individual company requirements, such as the ZREW facility.
