Energy mapping for large enterprises — who is covered and when
Who must carry out energy mapping in Norway, the energy threshold, the deadlines, and what the mapping must contain.
Norway's energy mapping regulation (energikartleggingsforskriften) entered into force on 1 October 2024 and obliges large energy users to map their energy use on a recurring basis. The exact wording and thresholds should always be confirmed against NVE's current guidance, but the practical questions we get are below.
Who must carry out energy mapping?
The duty targets large enterprises and organisations with substantial energy use across their buildings and operations. It is independent of sector — offices, retail, industry, logistics and public bodies are all in scope if they pass the energy-use threshold.
What is the energy threshold?
The requirement applies to enterprises with an average annual energy use above 2.5 GWh in Norway. Energy use is assessed across the organisation's buildings, installations and transport, not per individual building.
When did the requirement take effect and how often must it be repeated?
The regulation took effect on 1 October 2024. Mapping must be carried out and then repeated at regular intervals — every four years — so the data and the measure list stay current rather than becoming a one-off archive document.
What must the mapping contain?
A compliant mapping reviews energy use by building, process and energy carrier, identifies cost-effective measures with estimated savings and payback, and presents a prioritised measure list. It should be detailed enough to support investment decisions, not just satisfy a formal duty.
What happens if we do not comply?
The mapping is a legal obligation for covered enterprises, and authorities can follow up non-compliance. Beyond the formal risk, skipping it means leaving documented, profitable savings on the table — most mappings identify measures that pay for the work several times over.
How does SustEvo deliver it?
We structure the mapping so the data can be reused for energy management (ISO 50001), CSRD and EU Taxonomy reporting, and Enova applications. The output is a prioritised, costed measure list with a clear baseline — a basis for action, not a report that gets filed away.
