Project Highlights & Value
Technical Services for a Large-Scale Offshore Substation System
PowerMore provides technical services for 4 offshore substations, each with a capacity of 375 MW, as part of one of Poland’s major offshore wind power developments.
The project requires technical execution in a demanding offshore power infrastructure environment, with a strong focus on equipment quality, testing accuracy and readiness for commissioning.
Comprehensive Testing and Commissioning Support for Major Electrical Equipment
PowerMore’s scope covers critical stages from pre-installation testing through on-site acceptance testing, vacuum treatment and insulating oil processing.
These activities are carried out to help ensure that transformers and shunt reactors meet the required technical conditions before energization, commissioning and commercial operation.
Supporting High-Capacity Power Equipment
The technical scope covers major high-capacity electrical equipment, including:
- 8 × 225 MVA power transformers
- 4 × 140 MVAr shunt reactors
The scale and capacity of the equipment require controlled testing procedures, specialized technical expertise and strict compliance with project acceptance requirements.
Contributing to Installation Quality and Equipment Readiness
PowerMore’s technical services support the verification of equipment condition and installation quality before the main electrical equipment is placed into service.
Through electrical testing, vacuum treatment and insulating oil filtration, PowerMore contributes to ensuring that the transformers and shunt reactors are properly prepared for energization and reliable operation within the Baltica 2 offshore substation system.
