Energy Manager Obligation in Turkey: 2026 Guide

In short: In Turkey, every industrial enterprise whose three-year average annual total energy consumption is 1,000 TOE (tonnes of oil equivalent, "TEP" in Turkish) or more must appoint a certified energy manager; non-public enterprises at 50,000 TOE or more must also set up an energy management unit. Commercial/service buildings with at least 20,000 m² of construction area or 500 TOE, and public buildings with at least 10,000 m² or 250 TOE, are also covered, and obligated parties submit an energy consumption report by the end of March every year.

Legal basis: Law No. 5627 and the Efficiency Regulation

The energy manager obligation comes from Energy Efficiency Law No. 5627, published in the Official Gazette on 02.05.2007. The details are set by the Regulation on Increasing Efficiency in the Use of Energy Resources and Energy. This regulation was published in Official Gazette No. 28097 dated 27.10.2011; the text in force as of 2026 is the consolidated version last amended in Official Gazette No. 32669 dated 21.09.2024. There were also amendments in 2014, 2020, 2021 and on 06.07.2022; today's thresholds and reporting rules largely come from the 2020 and 2022 amendments.

The rules are administered by the Ministry of Energy and Natural Resources (Department of Energy Efficiency and Environment). The thresholds and deadlines below are taken from the consolidated regulation text; for a definitive assessment of your obligations, always check the current text on mevzuat.gov.tr.

Who must appoint an energy manager?

Article 9 of the regulation defines the obligated parties by consumption (TOE) and building size (m²). TOE is a unit that converts different energy types into a common measure; for the calculation steps, see our guide what TOE is and how to calculate it.

Important details:

• In industry the manager must be in-house: in industrial enterprises the energy manager is appointed from each enterprise's own employees and may not act as energy manager outside the enterprise where they actually work.
• Buildings may contract the service: if appointing an employee is not possible, a contract can be made with certified energy managers or authorised companies. Outside industry, one person may provide energy manager services to at most three sites.
• Campuses are aggregated: if a building group or campus contains several independent buildings, their construction areas are added together.
• A quality unit can be used: enterprises with a quality management unit in which the energy manager also works may designate that unit as the energy management unit.

How is the threshold determined? The three-year average rule

The regulation determines the obligation not from a single year but from the average of the annual total energy consumption over the last three years. Tracking whether you fall within scope is the responsibility of the facility management, not the Ministry. Consumption is converted to TOE using the calculation methodology published on the Ministry's website.

Example: Suppose a factory's total consumption over the last three years was 920, 1,040 and 1,090 TOE. The average is (920 + 1,040 + 1,090) / 3 = 1,016.7 TOE; since the threshold is exceeded, the enterprise must appoint an energy manager. If the same years were 880, 960 and 1,090 TOE, the average would be 976.7 TOE and no obligation would arise yet, even though the last year exceeded 1,000 TOE.

New facility exception: in newly established buildings and industrial enterprises, if first-year consumption exceeds twice the threshold (for example above 2,000 TOE in industry), the obligations apply immediately without waiting for a three-year average.

Who is an energy manager and how is the certificate obtained?

An energy manager is a person holding an energy manager certificate who is responsible, on behalf of management, for energy management activities. The rules in force as of 2026 are:

• Training is open to holders of a bachelor's degree in engineering or architecture, or in the mechanical, electrical, mechatronics or electrical-electronics departments of technical education faculties.
• Training is delivered by the Ministry, authorised institutions (universities, professional chambers) and authorised energy efficiency consultancy companies, with at least 80 hours of theoretical and practical lessons; attendance of at least eighty percent of each module is mandatory.
• The certificate requires passing the Ministry's central exam, held twice a year in April and October; a score of at least 70 out of 100 is a pass.

The energy manager's duties are listed in Article 8 of the regulation: setting an energy policy, monitoring consumption and costs and producing periodic reports, ensuring the supply, installation and calibration of the necessary meters and measuring devices, tracking specific energy consumption and energy intensity, running audits and efficiency projects, and organising staff training. The 2024 amendment added sustainability tasks such as determining carbon dioxide emissions, circular economy and water footprint; see our carbon tracking page for details.

Reporting calendar and the ENVER portal

Most obligations are fulfilled through the Ministry's ENVER (Energy Efficiency Portal), accessed via e-Devlet, Turkey's e-government gateway.

• Annual energy consumption report: those obliged to appoint an energy manager or set up an energy management unit submit their consumption data in the Ministry's format by the end of March every year (Articles 9/A and 32). This deadline is often confused; it is the end of March, not April.
• Energy manager notification: the appointed manager's identity, CV and contact details are notified to the Ministry. For new commercial/service buildings (over 20,000 m²) and public buildings (over 10,000 m²) this is done within one year after the occupancy permit; for those that become obligated later, within 60 calendar days.
• Change of manager: the departure of the current manager is notified within 15 working days; a new manager is appointed and notified within 60 calendar days.

Audit obligation: 4- and 7-year cycles

Article 10 of the regulation requires obligated facilities to carry out periodic energy audits:

• Industry (1,000 TOE or more): the audit is commissioned from authorised companies, or the enterprise performs it itself if it has staff with an industrial audit-project certificate who have been full-time insured employees for at least three months. The audit is renewed every four years.
• Buildings (commercial and service buildings over 20,000 m² / 500 TOE; public buildings of 10,000 m² / 250 TOE or more): the audit is renewed every seven years.
• Final audit reports are submitted to the Ministry by the end of March of the year following the audit. New buildings carry out their first audit in the seventh year after the occupancy permit, and new industrial enterprises in the fourth year after registration with the chamber of industry or commerce.

The audit requires measurements, calibrated instruments and a report in the Ministry's mandatory audit format. The audit is the foundation of energy efficiency projects; this is where measures with short payback periods are identified.

Is ISO 50001 mandatory?

Yes, for obligated parties it now is. Under paragraph 2 of Article 8 of the regulation, public buildings, commercial buildings, service buildings, power generation plants and industrial enterprises obliged to appoint an energy manager, as well as OSBs and enterprises obliged to set up an energy management unit, must establish and certify a TS EN ISO 50001 Energy Management System. The 21.09.2024 amendment states explicitly that certification is done through bodies accredited by TURKAK, the Turkish Accreditation Agency. Provisional Article 14 set the deadline for this obligation at the end of 2023, so as of 2026 the transition period has ended.

ISO 50001 is not an exemption that replaces the energy manager or the audit; it is a management system added on top of those obligations. For the structure of the standard see our article on the ISO 50001 energy management system, and for the implementation approach our ISO 50001 energy management page.

Sanctions

Article 33 of the regulation states that, following the Ministry's findings and inspections, the administrative sanctions in Article 10 of Law No. 5627 apply. The Law provides for administrative fines in cases such as failing to appoint an energy manager, failing to provide or incompletely providing requested information and documents, and not complying with reporting obligations. Fine amounts are updated every year by the revaluation rate and announced by the Ministry in a communiqué, so we do not quote amounts here. Check the announcement on the Ministry's energy efficiency portal for the current 2026 amounts. Providing any information and documents requested by the Ministry during an inspection is also mandatory under the regulation.

Checklist for facility managers

1. Collect the last three years of electricity, natural gas and other fuel consumption, convert them to TOE with the Ministry's methodology and calculate the average.
2. For buildings, determine the total construction area (including all independent buildings on the campus).
3. If you exceed the threshold, appoint a certified energy manager (in industry, your own employee) and notify via ENVER.
4. Put the 15-working-day / 60-calendar-day deadlines for a change of manager in your calendar.
5. Submit the annual energy consumption report by the end of March every year.
6. Track your audit dates: a 4-year cycle in industry, 7 years for buildings; the report is due by the end of March of the following year.
7. Make sure your TS EN ISO 50001 certificate is current and issued by an accredited body.
8. Check your metering infrastructure: if main incomers and large consumers are not metered, both the annual report and the ISO 50001 performance indicators remain weak.

How does Argus EMS help the energy manager?

Most of an energy manager's work is done with data: monitoring consumption, catching deviations and preparing the annual report with correct figures. Argus EMS automates this data side:

• On-site meters and energy analysers are read by the on-site Field Agent over Modbus TCP/RTU and M-Bus; data is sent to the server over TLS-encrypted MQTT.
• When the connection drops, data is buffered locally and sent once the connection returns, so annual totals are not distorted by missing data.
• Electricity, water, natural gas, UPS and generators are monitored on one platform, with hourly, daily and monthly consumption dashboards.
• Day/peak/night (T1/T2/T3) consumption breakdown, reactive ratio tracking with e-mail alarms, and e-mail alerts when thresholds are exceeded.
• Month-end consumption/cost projection and budget tracking, multi-site monitoring on one screen and data export make it easy to pull the raw data needed for reporting and audit preparation.
