The power companies' requirements for power factor phase asymmetry and documentation

2026-06-16·6 min reading

From 1 January 2026 the Common Regulation 2026 applies setting binding requirements for power factor phase asymmetry documentation and energy storage when connecting to the power grid. Here are the main requirements and what they mean for installations.

Introduction

Common Regulations 2026 is the utility companies' common regulations for connection of installations and appliances to the power grid. It came into force on January 1, 2026 and replaces the previous common regulations. (Source: elnet.dk/faellesregulativet-2026)

Power factor

The requirement applies to all installations connected to the power grid. Installations with many inductive loads (motors, transformers) and installations with frequency converters may need reactive compensation to comply with the limit.

Phase asymmetry

The requirement for phase asymmetry is relevant in three-phase installations with unevenly distributed single-phase loads — e.g. many sockets or single-phase heat pumps distributed unevenly on the phases. Always distribute one-sided loads evenly across all three phases.
