Energy Efficiency

Legal Requirements, Process and Documentation Guide

Energy efficiency is no longer a choice, but a legal requirement in Türkiye. Under Law No. 5627 on Energy Efficiency, industrial facilities with a total annual energy consumption of 1,000 TEP (tons of equivalent petroleum) or more are obliged to appoint an authorized energy manager and undergo periodic audits. Businesses that fail to fulfill this obligation may face administrative fines; more importantly, they will lose their competitive edge due to unnecessary energy costs.


Energy efficiency refers to reducing energy consumption without compromising production quality or living comfort. In industrial facilities, this concept encompasses optimizing machinery, heating and cooling systems, and lighting. Within the legal framework, it involves periodic audits and reporting processes conducted through Energy Efficiency Consulting (EEC) companies.

What is energy efficiency?

Legal Obligations and Sanctions

The Energy Efficiency Law clearly defines energy management obligations. Industrial establishments with annual energy consumption exceeding 1,000 tonnes of fuel oil (TEP) must employ an energy manager, conduct an energy audit every four years, and register with the Energy Efficiency Information System (EVBIS). Failure to fulfill these obligations may result in administrative sanctions imposed by the Ministry of Energy and Natural Resources. Furthermore, compliance with the legislation is a prerequisite for benefiting from public support and grant programs.

ISO 50001 Energy Management System Certification

ISO 50001 energy management system certification is a standard that internationally documents an organization's commitment to continuously improving its energy performance. Beyond legal compliance, ISO 50001 certification provides a strong competitive advantage in export markets, public tenders, and ESG (Environmental, Social, Governance) reporting. An ISO 50001 audit, conducted by an accredited certification body, comprehensively evaluates the company's energy consumption data, targets, and action plans.

Energy Efficiency Analysis: Scope and Process

Energy efficiency analysis, Energy consumption analysis is a systematic review that reveals the energy consumption profile of a facility. The process typically consists of the following stages:

  • Data collection: Invoices, meter readings, production data.
  • Field study: On-site inspection of equipment, heat losses, motor efficiency measurement.
  • Savings potential analysis: Cost-benefit calculation per measure.
  • Reporting: Technical report and proposal plan to be submitted to EVBIS.

Made for industrial facilities energy saving potential analysis, Because it includes investment payback periods, it is a critical tool for both regulatory compliance and financial planning.

How to Obtain an Energy Efficiency Certificate?

How to obtain an energy efficiency certificate? This is a question frequently asked by businesses. The basic steps can be summarized as follows:

For the process to be managed effectively, it is crucial that the chosen organization has TÜRKAK accreditation, both for the validity of the certificate and to prevent potential problems during the process.

1. A contract is made with an authorized EVD company or an accredited certification body.

3. Reports are prepared and submitted to the relevant institution.

2. The facility's energy audit and analysis study is completed.

4. In addition, a system setup and certification audit is conducted for ISO 50001.

Frequently Asked Questions

It is legally mandatory for industrial establishments with a total annual energy consumption of 1,000 tonnes of oil and steel (TEB) or more.

The process, including site survey and reporting, typically takes between 4 and 8 weeks to complete; this varies depending on the size of the facility.

It is not a legal requirement; however, it is becoming an increasingly sought-after criterion in public tenders and international supply chains.

It identifies energy losses and improvement opportunities in the facility in order of priority; and bases investment decisions on concrete data.

Working with TÜRKAK-accredited organizations is mandatory for regulatory compliance and document validity.

For facilities covered by legal regulations, energy audits must be renewed every four years.
