Goldbeck Solar finishes 90 MWp Postomino plant, ties into Polish grid

The German solar developer has completed the 90-megawatt-peak Postomino photovoltaic park in north-western Poland, integrating it with an existing wind farm’s high-voltage line in a cable-pooling arrangement set to supply electricity to about 32,000 homes.

Goldbeck Solar GmbH has finalised construction of the Postomino solar park in Nosalin, West Pomeranian Voivodeship. The installation delivers a nominal capacity of ninety megawatt-peak across approximately 110 hectares. Annual output is expected at 96 gigawatt-hours. According to the company, this volume could meet the yearly electricity demand of around 32,000 Polish households. The project entered planning in 2022 after winning a government auction for renewable capacity.

Infrastructure and capacity

The array is mounted on south-facing structures designed to maximise irradiation throughout the year. Civil works included a medium- to high-voltage substation rated at 30/110 kilovolts. Contractors also laid an eight-kilometre underground cable to connect the plant to the regional transmission network. Goldbeck Solar Polska managed engineering, procurement and construction for the entire scheme.

Postomino forms part of what the developer calls a cable-pooling project, linking solar output with a neighbouring onshore wind facility through shared infrastructure. The approach allows both technologies to feed the grid via a single connection point, reducing curtailment risk. Grid studies conducted during permitting indicated sufficient capacity headroom at the node. Polish regulators authorised the configuration under existing renewable integration rules.

Grid integration and commissioning

Electrical and protection tests are under way before the operator requests energisation. Commissioning is scheduled once measurements, relay settings and supervisory control systems receive approval from the distribution system operator. Goldbeck Solar expects commercial operations to begin later this quarter. Project financing details were not disclosed. No feed-in tariff applies; the plant will market its power through long-term contracts and spot trades.

“The combination of photovoltaics and wind power demonstrates how existing assets can accelerate Poland’s renewable build-out,” Chief Operating Officer Tobias Schüssler said in a statement dated on June 16. He added that the milestone was reached by a team of seventy engineers and technicians. Environmental documentation submitted during licensing estimates avoided carbon dioxide at 61,223 tonnes per year. Schüssler concluded, “The Postomino project shows that coordinated grid use is already feasible at utility scale.”
