Requirements for Charging Stations in Norway

Ina Marlen Andresen — Fri, 24 Apr 2026 11:48:00 +0000

In Norway, requirements are set for the energy meter in such installations, not for the charging station as a whole system. Detailed requirements for energy measurement are set out in the Regulation on requirements for electricity meters (the Electricity Meter Regulation). There is a requirement that such meters must have MID conformity assessment if they are sold after 01 January 2025. It is specified that electricity meters used to measure electricity supplied to electric vehicles in commercial contexts, but sold before 01 January 2025, may be used without conformity assessment. The requirement is not retroactive.

Requirements for measuring accuracy

The Electricity Meter Regulation sets accuracy requirements for energy measurement, regardless of whether a conformity assessment is in place or not. This means that all measurement of electricity supplied to electric vehicles in Norway must meet specific accuracy requirements laid down in the Electricity Meter Regulation.

Housing cooperatives, condominiums, charging for employees, and service providers

Justervesenet often receives questions about whether the requirement for conformity-assessed electricity meters applies to charging stations in housing cooperatives and condominiums. In such cases, the total amount of energy is measured by conformity-assessed electricity meters owned by a grid company.

The question concerns who is responsible for the internal distribution of energy within the housing cooperative or condominium. Justervesenet considers that if discrepancies between the total amount of energy delivered by the grid company and the actual energy used by residents are distributed through shared costs, there is no requirement for conformity-assessed sub‑meters.

However, it has been observed that there are various business models within such systems. Some operators offer invoicing of measured energy to consumers using the Open Charge Point Protocol (OCPP).

Justervesenet considers that certain business models involving lending, rental, or leasing combined with the sale of electricity may be regarded as commercial solutions. This applies in particular if the model involves direct invoicing per consumer, in the same way as commercial charging services elsewhere. Such models cannot therefore be regarded as simple cost allocation, and requirements for conformity‑assessed electricity meters may apply.

Changes in European regulations

At European level, changes to the Measuring Instruments Directive (MID) for energy measurement in charging stations are being planned. Some Member States believe that the entire charging station should be regulated as a measuring system, and detailed regulations have been proposed to cover this. Norway and other countries are working to limit the proposed changes so that they apply only to energy measurement.

In this context, Norway, together with Iceland and Liechtenstein, has contributed to an EEA EFTA comment as input to the decision‑making process in the EU. In the comment, we express concern that extending regulation to cover entire charging stations could lead to increased costs, hinder innovation, and delay the rollout of charging infrastructure. We also call for a systematic impact assessment before such extensive changes are introduced into the directive. The EFTA countries emphasize the importance of a balanced approach that ensures accurate measurements without creating unnecessary regulatory burdens. You can read more about the EEA EFTA comment here.

Any changes to the directive will in time be reflected in the Electricity Meter Regulation.

Transition period for new MID reqirements

As mentioned, the Regulation on requirements for electricity meters requires the installation of MID conformity‑assessed electricity meters in charging stations from 01 January 2025. In connection with possible changes to the MID as described above, a transitional period is expected for requirements related to energy measurement in charging stations. During this transitional period, all countries in the EU internal market are expected to accept national approvals.

Justervesenet will closely monitor developments and make the necessary adjustments to the Regulation on requirements for electricity meters. This may include allowing meters with national approvals from other EU/EEA countries to be used, provided they offer at least the same level of protection as the MID requirements. Until changes to the MID are clarified and the Electricity Meter Regulation is updated, we will therefore consider electricity meters with national approvals from EU and EEA countries to meet the requirements, as long as it can be documented that the quality of the measurements is at a level equivalent to the MID requirements.

Can You Trust That Fast Chargers Deliver the Correct Amount of Energy?

Ina Marlen Andresen — Mon, 20 Apr 2026 07:43:17 +0000

The number of electric vehicles on Norwegian roads is growing rapidly, and more and more drivers are charging at fast‑charging stations where payment is made per kilowatt‑hour. It is therefore crucial that the energy measured and billed actually corresponds to what the vehicle receives.

Lars Holhjem, Subject Matter Expert, Field Services

“Measurements are about trust. Manufacturers, suppliers, and owners of fast chargers need to be confident that the energy is measured correctly,” says Lars Holhjem, Subject Matter Expert at Justervesenet. “That way, consumers will also feel confident when charging their electric vehicles.”

From Time‑Consuming Tests to Answers in Minutes

Previously, testing fast‑charging stations was both time‑consuming and inflexible. Many tests were better suited to laboratory environments rather than real conditions at charging sites.

With the new solution, this has changed. Justervesenet now uses a mobile battery simulator that functions like an electric vehicle—except that the energy is converted into heat and the battery never becomes fully charged. Voltage, current, and energy can be controlled, unlike when testing with a real vehicle. Combined with a calibrated reference meter, this provides fast and precise answers as to whether the charging station measures correctly.

“This makes it possible to test charging stations the way they are actually used, not just under ideal conditions. That provides far more reliable results for both owners and users,” says Holhjem.

Testing can now be carried out efficiently in the field.

Benefits for the Entire EV Industry

The service is particularly relevant for manufacturers, owners, operators, and service providers of fast‑charging stations. They receive documented quality, better real‑world performance, and fewer complaints. The tests are also used as documentation for compliance with regulatory requirements. At the same time, EV drivers gain greater confidence that energy measurements are accurate.

Justervesenet acts as an independent and neutral third party, with strong professional expertise and long experience in metrology. The results are presented in reports that can be used internally as well as toward authorities and customers.

Facts About the Test Equipment

Justervesenet uses the reference meter EMOB 500 and the mobile battery simulator MBS 500 to test DC fast‑charging stations. The equipment is connected to the charging station like a regular electric vehicle via a CCS2 connector. The reference meter is calibrated by Justervesenet and measures the current, voltage, and energy delivered from the charging station to the battery simulator.

Preliminary specifications:

Up to 1000 volts and 500 amperes
A test at 800 volts and 400 amperes takes less than one minute
A full test with multiple measurement points can be completed in under ten minutes

Justervesenet offers testing services nationwide and also has the capacity to provide assistance across the Nordic region.

The use of the equipment and additional details about the testing will be demonstrated at the Nordic EV Summit.
