A photovoltaic installation gives you the opportunity to produce electricity from a renewable source and reduce some of your electricity costs, while protecting yourself from market price fluctuations. In addition to self-consumption, there are other subsidy mechanisms that can represent an interesting economic model, such as the guaranteed injection tariff or the market premium obtained through a call for tenders. The plant may be financed by equity capital or by a third-party investor, who may also be responsible for planning and building the plant.
In order to further stimulate the development of solar energy in Luxembourg, the ministry responsible for energy periodically, though not systematically, launches calls for tenders focused on the implementation and operation of large-scale photovoltaic plants.
Between 2018 and 2023, five calls for tenders with operating subsidies were launched, resulting in a total installed capacity of 127.65 MWp. Additionally, two calls for projects with investment subsidies were organized, adding a capacity of 79.65 MWp.
According to the Ministry of the Economy's indicative multi-annual timetable, an additional total photovoltaic capacity of around 300 MW is planned between 2025 and 2028 for large-scale installations. The schedule can be viewed on guichet.lu.
