About Rensys Ltd.

Founded in Hamm to supply Eastern European utilities. Expanded from electrical components to transformers, switchgear, and substations—focused on shorter lead times and strong manufacturers.

A subsidiary in Poznań opened to grow the Eastern European MV/LV market. The local presence improved market access before the company was sold to a manufacturer in 2003.

Shift to EPC for MV/HV projects, delivering complete substation solutions from planning to commissioning—enabling reliable single-source delivery in a changing market.

A Poland-based service unit introduced 24/7 support for grid operators. Entry into EHV up to 420 kV and disconnector sales enabled first EHV projects in Eastern Europe.

Lecturer at SRH Hamm (Power Network Economics) involving the development of teaching materials, lectures, laboratory practicals, excursions, and a research program on the integration of pumped-storage power plants into hard coal mines. Founded Rensys Management Consulting in Germany and Rensys Sp. z.o.o. in Poland to advise international clients and develop grid connections for wind farms, specializing in renewable energy and branding under “Renewable Energy Systems”.

Participation in grid connection projects for German offshore wind farms such as Borkum Riffgrund and Gode Wind with more than 1 GW of capacity. Focus on technical solutions, stakeholder management, and cable routing in complex sea crossings.

Analysis of the use of offshore wind power for hydrogen production at sea, including costs, storage alternatives, and direct injection into the gas grid. Participation in grid connection projects for German wind farms (e.g., Borkum Riffgrund, Gode Wind, >1 GW) with a focus on technical solutions, stakeholder management, and cable routing in complex sea crossings.

Implementation of a 20 MW electrolysis project to produce green hydrogen from wind power for CO₂-neutral bus mobility, and development of a sales network in Poland for medium-voltage switchgear, with a focus on grid operators and EPCs to ensure reliable energy supply.

Market introduction of an innovative wind measurement technology in Poland, including market development, customer presentations, and trade fair appearances. Conducting technical due diligence for several Polish wind farms. Product management of SCADA, wind farm, and medium-voltage systems at a German wind turbine manufacturer, including responsibility for turbine options and power-boost functions.

Leading the implementation of a global control centre for wind turbines. Execution with an agile project setup, IoT integration, and selection of suitable software solutions.

Concept and further development of services at the interface between grid infrastructure, energy generation, and commercial services. Focus on product development and sales.

Planning of multi-MW charging stations for bus and passenger-car depots in Germany with grid integration to handle high power peaks. Training of engineers and teaching staff at a digital substation in Zambia, including both theoretical instruction and practical on-site exercises.

Overall responsibility for the power supply of a wastewater treatment plant, including budget management, team leadership, and construction site coordination under challenging project conditions.

Founding of Rensys GmbH in Hamm, Germany, including team building for growing customer projects. Establishment of Segrico Süd in Montenegro for service projects in Southern Europe to enable rapid scaling and quality assurance. Planning and negotiation for the replacement of 220/10 kV transformers with 380/10 kV transformers, including a concept for partial operation during the conversion.

Project management for the construction and modernization of the 110/20 kV grid infrastructure in Bavaria — from planning and implementation to commissioning.

Management of a 250 MW battery storage project including planning, coordination, and risk management for grid integration; technical leadership of electrolysis projects with several hundred MW of capacity from grid planning to commissioning; development and implementation of connection concepts for large generation parks such as Boldekow and Schadewohl.

Project management for the expansion of a 380 kV substation. Coordination of all construction phases, stakeholder management, and ensuring compliance with schedule and budget targets.
