Beyond the 2026 EU Energy Audit Deadline: Why Circuit-Level Metering Matters

IVY EM719028 brings Class 0.5 three-phase CT metering and RS485 Modbus connectivity to industrial and commercial energy monitoring

Europe’s 2026 energy audit milestone has put measured energy data back in focus. Under Article 11 of the revised EU Energy Efficiency Directive, enterprises consuming more than 10 TJ of energy annually on average over the previous three years, without an energy management system, were required to complete their first energy audit by 11 October 2026, subject to national implementation rules. Audits are expected to use up-to-date, measured and traceable consumption data, including electricity load profiles.

For factories, warehouses and commercial facilities, a main utility meter shows total consumption—but rarely explains which production line, HVAC system or distribution circuit is responsible. After the audit, operators need more granular data to assess improvement opportunities and track the results of energy-saving measures.

This is where CT-operated sub-metering becomes useful. By working with external current transformers, a compact panel-mounted meter can monitor selected three-phase circuits without carrying the primary load current through the meter itself.

IVY METERING’s new EM719028 is a three-phase, four-wire DIN-rail CT energy meter designed for industrial and commercial distribution systems. It supports Class 0.5 energy measurement, bidirectional import/export metering, RS485 communication with Modbus RTU and DL/T645, configurable multi-tariff functions and S0 pulse output.

When integrated with suitable current transformers, data gateways and energy management software, the EM719028 can provide circuit-level consumption records for dashboards, load comparisons and ongoing energy-performance reviews. Its RS485 interface also makes it practical for integration into existing building and industrial monitoring networks.

An energy meter does not replace a qualified energy audit or automatically satisfy regulatory obligations. It can, however, supply one of the essentials of effective energy management: reliable measurement at the points where electricity is actually used. As European businesses move from audit findings to measurable improvements, IVY EM719028 offers a practical foundation for more transparent and connected power monitoring.
