Summary of the 2025 Testing Season – thank you for your cooperation!

Summary of the 2025 Testing Season – NC RfG Tests

We have completed the 2025 testing season for generating units. Over the past year, we carried out NC RfG compliance tests and power quality measurements (PQM) for facilities with a total capacity of more than 50 MW. These included both photovoltaic farms and cogeneration units, and their successful execution was possible thanks to cooperation with numerous grid operators and EPC contractors.

We worked on installations across all regions of Poland, gaining experience in diverse technical and environmental conditions.

We would like to thank all clients and partners for their trust and smooth cooperation throughout the projects. Thanks to you, this season was exceptionally intensive and at the same time highly rewarding.

Cooperation in 2026

We are beginning to plan the next testing season and are now accepting bookings for 2026. Early contact allows us to plan resources properly and ensure timely execution of all required tests.

We offer comprehensive support for the commissioning of generating units, including:

• development of test schedules,

• execution of NC RfG tests,

• power quality measurements (PQM),

• preparation of complete documentation required by the operator,

• technical and formal support at every stage.

In 2026, we will carry out NC RfG tests for type B, C and D facilities, including photovoltaic farms and cogeneration units, for all grid operators in Poland.

The Importance of NC RfG Tests

NC RfG tests (pursuant to Commission Regulation (EU) 2016/631 of 14 April 2016) and power quality measurements (conducted in accordance with EN 50160:2023, the Regulation of the Minister of Climate and Environment of 22 March 2023 [required in Poland], and the relevant grid codes [IRiESD]) constitute one of the key stages in the commissioning process of generating units. Their proper execution confirms compliance with operator requirements and ensures stable operation of the facility under grid conditions.

During the previous season, we performed tests across multiple sites throughout Poland. As a result, we gained extensive experience with various equipment configurations, automation systems and control setups. Each facility requires an individual approach and thorough preparation. Therefore, we offer full support — from preliminary arrangements and development of procedures to field measurements and preparation of final reports.

Why Are PQM Tests So Important?

PQM tests verify the quality of energy fed into the grid. We analyse harmonics, voltage dips, fluctuations, unbalance and other parameters required by the applicable standards. The results provide a solid basis for operator approval and final commissioning. When conducted by an experienced team, they also prevent delays, repeated tests and unnecessary costs.

Bookings for the 2026 Season

The year 2026 is expected to be intensive. Early scheduling allows us to allocate resources in advance, prepare documentation and conduct the entire testing process efficiently. We perform measurements for PV farms and cogeneration units (type B and C), cooperating with all distribution system operators in Poland.
