Solutions tailored to the DSO’s requirements, the scale of the project, and the client’s existing infrastructure.
Timely and reliable project delivery with solutions tailored to your project’s needs
Specialists in renewable energy grid connections
NEZE Sp. z o.o. delivers electrical power engineering projects throughout Poland. We design and build grid connection infrastructure for power generation facilities (PV, Wind, Biogas, CHP) and Battery Energy Storage Systems (BESS) – from concept and design to commissioning. We specialize in grid connections for renewable energy sources, with a particular focus on photovoltaic farms. We also design and construct substations and electrical networks for renewable energy projects, as well as grid connections for renewable installations at industrial facilities.
MV/LV Substations and Power Infrastructure
NEZE Sp. z o.o. delivers comprehensive projects for connecting generation sources and industrial facilities to the power grid. We design and build MV/LV substations and power infrastructure, including both new grid connections and the modernization of existing electrical networks.
From consulting to delivery – comprehensive support for investors
We deliver comprehensive projects while providing full technical and administrative support, representing investors in all interactions with Distribution System Operators (DSOs) across Poland. By combining engineering expertise with practical implementation experience, we ensure efficient, timely, and reliable project delivery.
Precise and Compliant
We specialize in the design of grid connections and power infrastructure for photovoltaic farms, biogas plants, wind farms, and cogeneration facilities (natural gas, biomass, landfill gas, and wastewater treatment plants). We deliver projects from the initial concept through detailed design documentation, in compliance with DSO requirements and applicable standards.
Reliable and proven in practice
We provide comprehensive construction services for grid connections for generation sources, MV/LV transformer substations, MV and LV power lines, electrical installations for industrial facilities, and telecontrol cabinets (R_GEN – generation switchboards), as well as network upgrades and utility conflict relocation. We also provide design supervision, technical acceptance support, and turnkey assistance throughout the commissioning and handover process. For General Contractors, we offer flexible cooperation tailored to the required scope of work for generation source and BESS grid connections.
Efficient from concept to commissioning
We manage the entire DSO grid connection process, from the initial concept to the commissioning of the installation. We coordinate every stage of the project – from obtaining Grid Connection Conditions (GCC), preparing and securing approval of the design documentation, commissioning activities (including telecontrol, protection systems, and testing), assisting with DSO agreements, reviewing electricity supplier contracts, through to the final documentation and energization. Acting under a Power of Attorney, we represent the investor throughout the entire grid connection procedure. We ensure technically optimized solutions, full compliance with DSO requirements, and the efficient delivery of projects through to successful commissioning and final acceptance.
Safe and compliant with standards
We prepare transformer substations for safe and reliable operation by performing testing and measurements, verifying compliance with the design documentation, and providing support during the DSO acceptance process.
This is a critical stage that ensures the reliability, safety, and long-term performance of the installation. In addition, we offer remote monitoring, remote control, diagnostics, and maintenance services through our MyEn platform. We also provide regular inspections and servicing of transformer substations, and in the event of a failure, our rapid-response service team helps minimize downtime in power generation or industrial operations.
Reliable and tailored to your project
We provide expert consulting on grid connections, power supply upgrades, and the optimization of technical solutions. By combining engineering expertise with practical implementation experience, we deliver solutions that are reliable, safe, and economically viable.
We work with General Contractors, investors, companies, and public institutions across Poland, providing comprehensive support at every stage of the investment process.
