Energy Audit Framework
Voluntary, subsidised energy audit
For municipalities, joint municipalities, parishes, foundations, and companies with annual energy consumption under 2 700 MWh
A voluntary, subsidised energy audit is a comprehensive assessment of energy use and energy-saving potential, carried out and reported in accordance with established guidelines.
A subsidised energy audit carried out by a professional is an effective tool for reducing the site’s energy costs and greenhouse gas emissions. The energy-saving opportunities identified in completed energy audits reduce energy costs by nearly 20% on average.
Mandatory enterprise energy audits
The legal obligation is determined based on the company’s energy consumption
The legal obligation is determined based on the company’s energy consumption.
The amended Energy Efficiency Act, which entered into force at the end of 2025, obliges companies to carry out an enterprise energy audit every four years if their annual energy consumption is 2 700–23 600 MWh.
Mandatory enterprise energy audits are not eligible for energy aid.
Subsidised in-depth investigation
For municipalities, joint municipalities, parishes, foundations, and companies with annual energy consumption exceeding 2 700 MWh.
Through an in-depth investigation, a municipality, joint municipal authority, or company participating in the Energy Efficiency Agreement can, with financial support, assess how to improve its energy efficiency, increase the share of renewable energy, or otherwise make its energy use low-carbon.
