New MEKH regulation on sub-meters:

The MEKH regulation on sub-meters entered into force on 1 January 2021. It obliges economic operators to provide individual sub-meters for consumers with a certain power output. The obligation to install sub-metering is imposed by the EU to ensure that all metering installations are compliant with the new legislation. KRL is a partner in the implementation of the sub-metering system covered by the regulation to ensure our customers comply with the regulations, and our energy management system also assists energy specialists.

We have summarised the key points:

• (1) Sub-metering is required to be installed by the entity where electricity use cannot be determined based on installed capacity and operating time
  
  i) for stand-alone electrical installations with a rated output of more than 100 kW (in particular compressors, motors, pumps, other drives and process equipment),
  
  ii) heat generating and air-conditioning installations with a rated electrical output exceeding 140 kW.
  
  

• (2) The economic entity subject to the obligation to use an energy consultant shall install a sub-meter to monitor its electricity consumption where the maximum installed simultaneous power demand of the stand-alone electrical equipment, heating and air-conditioning systems, excluding the equipment for heating and air-conditioning, measured by the sub-meter referred to in paragraph 1, supplied via a single entry point and connected in a process sequence (in particular: machinery, production line, production hall or building) exceeds 200 kW.
  
  
• (3) Exempted from the sub-metering obligation provided for in paragraph (1) are equipment whose operating time does not exceed an average of 2000 operating hours per year over the three years preceding the year under consideration.
  
  

(2) Section 3 shall enter into force on 1 January 2021.

(3) Section 7 shall enter into force on 1 January 2022.
