Baltic Power Wind Farm Installs All 76 Vestas Turbines

Estimated reading time: 6 minutes · Last updated: 1 November 2026

Global Wind Service has finished installing all 76 turbines at Baltic Power, the roughly 1.2 GW offshore wind farm that ORLEN and Northland Power are developing together. Every unit is a Vestas V236-15 MW machine. The project has already fed its first electricity into Poland's national grid. Final commissioning is now underway, and it is the last step before full commercial operation. GWS describes Baltic Power as Poland's first offshore wind farm. Its crews handled pre-assembly, offshore installation, commissioning and high-voltage work across the campaign. No date for commercial operation has been given. The milestone shows that the heavy physical work is done. It also shows how much electrical work sat behind it.

This achievement reflects the strong cooperation between GWS, Vestas, Baltic Power and all project partners.

What GWS Has Finished, and What Is Still Pending

The contractor Global Wind Service (GWS) has confirmed that every one of the 76 turbines planned for Baltic Power now stands in position. The farm is a joint project between ORLEN, a Polish energy company, and Canada-based Northland Power. Its capacity is put at approximately 1.2 GW.

Installation is not the same thing as operation. Baltic Power has already exported first power to the national grid. That shows the electrical path from the turbines to shore is working. The farm is still in final commissioning. In this phase, turbines and the wider system are tested and signed off before the owners declare commercial operation.

GWS gave no date for commercial operation. Neither ORLEN nor Northland Power is quoted on timing. The contractor presents the project as close to the finish line. Until the developers name a date, though, the end of commissioning remains the open question.

Inside the High-Voltage Work Behind the Installation

Jakob Dehlbaek, Offshore Divisional Director at GWS, called the installation a significant milestone. "We are proud that our teams have contributed their expertise across pre-assembly, offshore installation, commissioning works and high-voltage works," he said. He added that the result reflected close work with Vestas, Baltic Power and the other partners on the project.

The electrical work is the easiest part of that list to overlook. GWS ran its high-voltage tasks through its own in-house department. That team handled HV terminations and HV commissioning, the connection and testing work that has to be done before high-voltage equipment can carry power.

The same department supplied HV Control Person functions. According to GWS, the job of whoever fills that role is to protect personnel working near high-voltage equipment. The company says keeping these skills in one team simplified coordination, because electrical safety had to run in parallel with mechanical and electrical installation.

Across every phase, GWS drew on mechanical, electrical and rope access specialists. Rope access is a way of reaching work positions on tall structures using ropes and harnesses instead of fixed platforms.

Why 15 MW Turbines Raise the Stakes for Installers

Each Baltic Power turbine is a Vestas V236-15 MW, rated at 15 megawatts per unit. Multiplied across 76 machines, that comes to about 1,140 MW of combined turbine rating. This is a little below the approximately 1.2 GW figure given for the project. The difference is not explained, and an exact capacity figure from the developers would settle it.

GWS said the turbine's size and technical requirements called for specialist knowledge, adaptability and close coordination between its teams. Crews were working at height on very large structures while also managing complex electrical systems. That combination strains both people and logistics.

The campaign also drew on a relationship GWS already had with Vestas. Crews who know how a manufacturer's equipment, tolerances and procedures behave tend to run into fewer problems when they install and commission it. That matters more as individual machines get bigger and more complex.

What Baltic Power Means for Poland and for GWS in Szczecin

GWS describes Baltic Power as Poland's first offshore wind farm. That makes the end of turbine installation a marker for an industry the country is only now building. Kelly Lippke, a staff writer at Energies Media, linked the project to Poland's broader effort to expand its renewable energy capacity.

The project also has a local side for the contractor. In Szczecin, a city on the northwest coast of Poland, GWS runs one of its major offices. A local workforce there supports the company's international operations, so part of the expertise behind the country's first offshore build came from a Polish base.

GWS has called Poland an important part of its wider business. Baltic Power gives the company a domestic offshore reference to go with its onshore work in the country. That could matter as further Polish offshore projects come forward, although GWS has not said what work it is pursuing next.

What could speed or slow the path to commercial operation

The bottom line

Baltic Power has crossed its most visible threshold. All 76 Vestas V236-15 MW turbines are standing, and first power has reached Poland's grid. What has not happened yet is commercial operation, and that depends on how final commissioning goes. Neither ORLEN nor Northland Power has said when that will finish. GWS frames the farm as nearly complete, which is fair for the construction work. The developers still have to confirm the timeline and clarify a capacity figure that sits above the combined turbine rating. For GWS, the job shows a contractor that kept high-voltage safety in-house on a demanding campaign, and it gives the Szczecin operation a home-market offshore credential.

What to watch

• Watch for ORLEN and Northland Power to declare full commercial operation at Baltic Power; no date has been set.
• Watch for the developers to confirm the farm's exact installed capacity, which would explain how the 76 turbines relate to the approximately 1.2 GW figure; no date has been given.
