Floating solar power plants in reservoirs in the public domain


In the absence of approval by the Council of Ministers, the Government is taking a step forward to promote the installation of floating solar power plants in reservoirs in the public domain.

Full of National Water Council, Chaired by the Vice-President and Minister for Ecological Transition and the Demographic Challenge (MITECO), Teresa Ribera, endorsed the draft Royal Decree that will regulate the system for installing floating photovoltaic power plants in reservoirs located in the public domain (DPH) to hydrographic basins whose management corresponds to the General Administration of the State.

The rule, which must be approved by the Council of Ministers, will expand the catalog of renewable technologies available and will contribute to increasing the capacity of electricity generation from renewable sources.

The floating photovoltaic systems They have better energy performance than terrestrial systems thanks to the cooling effects of water and the reduction of the presence of dust, among other aspects. Another aspect appreciated by experts is the possibility of adding floating solar capacity to existing hydroelectric plants. “The solar capacity it can be used to increase the production of such installations and the optimization of existing evacuation infrastructures, and can also help to manage low water periods”they claim.

The potential field of application of the RA will be the reservoirs of public and private property located in the public hydraulic domain in the inter-municipal basins, dependent on the General Administration of the State. The floating solar photovoltaic production installation will be carried out under a concession regime for each project for a maximum duration of 25 years, extensions included, and will be limited to heavily modified or artificial water bodies.

The bases approved by the Water Council also provide that the granting of the concession will be conditional on compatibility with the Hydrological plan of the demarcation, the trophic state of the reservoir concerned, the pre-existing rights and uses, the impact on the safety and operation of the infrastructures, and the prior environmental assessment procedure. The maximum percentage of total usable area for the installation of floating panels will be between 5% and 20%, depending on the eutrophication level of the dam water body.
