<\/figure>Self-consumption should not be confused with self-sufficiency, which involves covering 100% of your electricity needs with your own production. Achieving self-sufficiency requires designing and sizing an installation capable of meeting all your electricity demands at all times. However, since most consumers remain connected to the electricity grid, pursuing self-sufficiency can be very costly and is often not a practical or necessary approach.<\/p>\n<\/div><\/div>\n\n\n\n
<\/span>Definition of the requirements<\/h3>\n\n\n\nIf a company produces energy, it can also consume it. There are various ways of consuming or sharing your company’s production.<\/p>\n\n\n\n
Analysing the potential for self-cosumption and electricity sharing<\/h4>\n\n\n\n\n- What is the potential for harnessing solar energy?<\/a><\/li>\n\n\n\n
- What is my company’s energy consumption profile and is there any potential for self-consumption? – Tool for comparing load curves and simulating sharing groups?<\/a><\/li>\n\n\n\n
- Are there potential consumers outside the company who could participate in sharing the electricity (other company units, neighbours, etc.)?<\/li>\n<\/ul>\n\n\n\n
The different types of self-consumption<\/h4>\n\n\nIndividual self-consumption<\/strong><\/span><\/summary>\n\nThe electricity generated by a building is used directly by its occupants, making the energy producer and consumer the same entity. To maximize the self-consumption rate, it’s important to align energy use as closely as possible with production. If there is surplus electricity, it can either be fed into the grid or stored for later use\u2014either in a solar battery or by powering equipment like a heat pump that charges a buffer tank. Any electricity fed into the grid is compensated at the wholesale market price for that month. During times when production is low or absent, you can draw on stored energy or rely on the electricity grid.<\/p>\n\n<\/div><\/details><\/div>\n\n
Collective self-consumption<\/strong><\/span><\/summary>\n\nCollective self-consumption means sharing the produced energy:<\/p>\n\n\n\n
\n- within a condominium (several network users in the same building, behind a single connection point) ;<\/li>\n\n\n\n
- between neighbours (maximum of three network users), where the distance between the two furthest injection or withdrawal points does not exceed 100 metres;<\/li>\n\n\n\n
- or in the specific case of a network user with several supply points (e.g. an agricultural, craft or industrial establishment).<\/li>\n<\/ul>\n\n\n\n
Collective self-consumption is only possible with a single low-voltage electricity grid operator. The first two cases are exempt from the grid usage tax for shared electricity, and the third case is only exempt if the maximum distance of 100 metres is respected.<\/p>\n\n\n\n
The energy is shared based on an allocation scheme to be defined between the members of the sharing group. Agreements must be drawn up with the grid operator and between the members of the sharing group to set up this distribution.<\/p>\n\n<\/div><\/details><\/div>\n\n
Energy community<\/strong><\/span><\/summary>\n\nAn energy community is possible in two scenarios<\/p>\n\n\n\n
\n- the local energy community (sharing of renewable energy when the distance between the two furthest points of injection or withdrawal does not exceed 300 metres, and exemption from network use tax, a single electricity network operator and low voltage)<\/li>\n\n\n\n
- the national energy community (without geographical restrictions, but without exemption from the grid usage tax).<\/li>\n<\/ul>\n\n\n\n
By law, an energy community must be set up as a legal entity. With the exception of large companies, any private or legal entity, including public organisations, is eligible. All types of business are permitted. The production plants ( possibly at national level) can be joint or individual.<\/p>\n\n<\/div><\/details><\/div>\n\n\n![\"\"](\"https:\/\/dev.klimapaktfirbetriber.lu\/wp-content\/uploads\/2024\/08\/Graph_Autoconso_Entreprise-1024x502.png\")

Electricity allocation scheme<\/h4>\n\n\n\n
When you opt for a collective self-consumption system or an energy community, by default the electricity will be shared in proportion to the consumption of the various supply points. However, it is important to know that it is also possible to allocate electricity according to different preferences. The members of the community can also devise a more complex allocation scheme, by giving priority to certain consumers or by defining the allocation percentages themselves.<\/p>\n\n\n\n
Practical information on sharing electricity<\/h4>\n\n\n\n\n- An energy report (quarter-hourly detail) is drawn up by the network operator, according to the chosen allocation scheme. This report is sent monthly to the self-consumers\/sharing group representative.<\/li>\n\n\n\n
- Participation in collective self-consumption or in an energy community is voluntary.<\/li>\n\n\n\n
- Each member of an energy community can sign individual electricity supply contracts with suppliers of their choice.<\/li>\n<\/ul>\n\n\n\n
<\/span>Subsidy application<\/h3>\n\n\n\nCall for tenders for investment subsidies for large-scale photovoltaic power plants<\/h4>\n\n\n\n
In principle, investment subsidy encourages companies to produce all or part of their own energy through the granting of a subsidy paid at the time the photovoltaic plant is commissioned.<\/p>\n\n\n\n
This 4th call for tenders comprises 3 lots. For each lot, sublots dedicated to photovoltaic installations with battery storage are now included. The maximum subsidy amounts range from \u20ac395\/kWp to \u20ac1,100\/kWp for installations without electricity storage, and from \u20ac515\/kWp to \u20ac1,280\/kWp for installations with storage. The total budget for this call for tenders is \u20ac17 million.<\/p>\n\n\n\n
The subsidy is awarded through a project call. This is a competitive process: projects requesting the lowest subsidy relative to installed capacity are selected, within the available budget.<\/p>\n\n\n\n
