We made an infrastructure capable of connecting 55 MWp (of which we connected 49 MWp, see above) in the “design and build” formula, and additionally we have created a microgrid for 10 households powered by an intelligent MV grid system.
The Wind Park in Potęgowo consists of 81 turbines with a total capacity of 219 MW. It is the largest onshore wind farm project in Poland and one of the largest onshore wind farms in Europe. According to calculations, the construction of the Potęgowo Wind Farm will reduce carbon dioxide emissions by approx. 514 thousand tons per year. Thanks to the unique layout of the wind turbine system, it was possible to avoid the migration, grouping and foraging routes of bird nesting. Noise standards will not be exceeded in the towns located near the farm. The project is divided into stages – Potęgowo East (completed and launched) and Potęgowo Południe.
Solar farm with a capacity of 20 MW. The projected annual electricity production is 20 GWh, which will reduce emissions of 17 tons of CO2 annually and will supply 9,000 households. The development area is approximately 32 ha. The farm consists of 36,000 photovoltaic panels, 90 inverters and 10 transformer stations. For the purposes of power evacuation, we will build 11 km of medium voltage cable line.
The farm is being built in post-mining areas – it is a peculiar sign of the times and the energy transformation taking place.
The Dębsk Wind Farm consists of 55 turbines with a total capacity of 121 MW. The estimated annual production of the Dębsk WF will amount to approximately 366 GWh, which corresponds to the electricity demand of 183,000 households. The implementation of the project makes avoiding pollutant emissions of up to 318,000 tons of CO2, 318 tons of SO2, 318 tons of NOx, 106 tons of CO and 18 tons of suspended matter possible. The expected duration of the project is two years, and the first electricity is to flow to consumers as early as 2022.
For KGHM Polska Miedź S.A. (Copper Mine) we designed construction and detailed design, delivered the equipment and launched the 110kV, 10kV and 400V infrastructure along with the automation, control and management systems necessary to connect to the 110kV grid in the Surface Climate Station and the Generation Unit Station operating in a trigeneration system.
We have completed a comprehensive modernization of the existing HV/MV station. The works included the construction of a new transformer bay and replacement of two existing transformers with new ones, replacement of transformers and implementation of the auxiliary power supply system with batteries, telemechanic, measuring and telemechanical systems.
We have also prepared a visualization system based on Axis solutions, integrating, among others, chilled water preparation, water treatment stations, gas aggregate monitoring system, BMS, MV power system monitoring, reporting system.
During the works, the challenge was to ensure the uninterrupted operation of the cooling systems of mining shafts. It was required, among other things, to implement anti-freezing protection for the installation in case the mine did not receive the cold. The implemented solution is based on a proprietary algorithm that continuously calculates the temperature distribution along the entire pipeline (over 4.5 km long).
As a break in the supply of chilled water of more than 30 minutes results in the evacuation of the entire shaft, we also needed to ensure the reliability and continuity of production.
We have completed the turnkey implementation of photovoltaic farms with a total capacity of 33 MWp, and our work was carried out in the full EPC formula.
