This action, promoted by the public company of the Generalitat de Catalunya, allows sharing green energy generated on a public roof with other nearby facilities in the Alt Urgell. The core of the system is located on the roof of Institut La Valira, where 227 solar panels have been installed, capable of generating about 162,500 kWh annually.
Thanks to the collective self-consumption modality, surplus energy that the producing building does not consume is distributed to other public buildings located within a 2-kilometer radius, without having to pay tolls or charges. This system is now fully operational as of this week.
Currently, the building that receives the most energy from this distribution is the Jutjats de la Seu (Courts) (43%), followed by the Mossos d'Esquadra police station (41%). The remaining 16% corresponds to the necessary consumption of Institut La Valira, which acts as the generation base.
“"It allows saving costs and losses, coordinating surplus buildings, which produce more energy than they need to operate, such as institutes, towards deficit buildings, such as police stations."
This installation is part of the progressive deployment of collective self-consumption systems that L'Energètica is carrying out throughout Catalunya. The company assumes the investment and execution of the photovoltaic work, sizing the plant to take advantage of the entire useful surface of the roof.
Using an algorithm, optimal distribution coefficients are calculated and assigned to distribute the generated energy between the producing building and the associated consumers. The ultimate goal is to maximize the efficiency of Generalitat resources, leveraging the potential of the 1,400 public roofs suitable for installation to advance towards the decarbonization of the Catalan public administration.
