Statistical Classification of Economic Activities in the European Community, Rev. 2.1 (NACE Rev. 2.1) - Section D

This section includes the generation, storage, control, distribution, trade and brokerage of electric power or of gaseous fuels for energy supply through a permanent network of lines, mains and pipes. Energy supply for industrial parks or residential buildings is included.

This section therefore includes the operation of electricity and gas utilities.

This group includes the generation of electric power, transmission from generating facilities to distribution centres and distribution to end users. Trade and storage of electric power are also included.

This class includes:
- operation of generation facilities that produce electricity from non-renewable sources (e.g. natural gas, coal and other fossil fuels), and from emission-free non-renewable sources (e.g. nuclear)

This class includes:
- operation of generation facilities that produce electricity from renewable sources (e.g. gaseous biofuels, hydropower, on-shore and off-shore wind power, photovoltaic solar energy, thermal solar energy, geothermal energy, and tide, wave and ocean energy)

This class includes:
- operation of high-voltage transmission systems that convey electricity from the generation facility to the distribution system

This class includes:
- operation of high-voltage, medium-voltage and low-voltage distribution systems (e.g. lines, poles, meters and wiring), which convey electric power received from the generation facility or the transmission system to the end user
- rental and leasing of electricity distribution networks
- distribution of electricity into electricity mains/networks

This class includes:
- sale of electricity on own account

This class includes:
- conversion of electrical energy into a form of energy which can be stored, the storing of such energy, and the subsequent reconversion of such energy into electrical energy (e.g. operation of pump storage facilities, compressed air storage facilities, or battery storage facilities)
- distribution of stored electricity into electricity mains/networks

This group includes the manufacture of gas, the storage and the distribution of natural or synthetic gas to the user through a system of mains.

This class includes:
- production of gaseous fuels for energy supply through a gas distribution network (e.g. by carbonation of coal, gasification of lignite, electrolysis or methanisation)
- production of gaseous fuels for energy supply with a specified calorific value, by purification, blending and other processes from gases of various types, including natural gas or hydrogen
- production of biogas for the purpose of gas supply (e.g. from sewage sludge, manure, waste)
- production of gaseous biofuels for energy supply through a gas distribution network

This class includes:
- transport, distribution and supply of gaseous fuels of all kinds through a system of mains
- rental and leasing of gas utility networks

This class includes:
- sale of gaseous fuels through mains on own account

This class includes:
- storage of gaseous fuels
- storage of hydrogen gas

This class includes:
- production, collection and distribution of steam and hot water for heating, power and other purposes
- production and distribution of cooled air (e.g. for air conditioning supply)
- production and distribution of chilled water for cooling purposes
- production of ice from natural water for cooling purposes

This class includes:
- activities of brokers or agents, who arrange the sale of electricity via power distribution systems operated by others
- activities of gas brokers or agents, who arrange the sale of gaseous fuels via gas distribution systems operated by others
- activities of brokers and agents for commodity and distribution capacity exchanges for gaseous fuels
- activities of brokers and agents for the operation of electricity distribution and transmission capacity exchanges for electric power
