The Port of Tarragona will install 708 photovoltaic modules on the roofs of sheds one, two, three, and four of the Moll de Costa to increase its energy self-consumption. The new plant will provide 300 kWp of power and will be added to the 750 kWp that the Port Authority of Tarragona currently generates.
The expansion comes as the facility already produces its own electricity, but is still preparing new phases to approach 2 MW of photovoltaic generation. The immediate leap will focus on a very specific area of the port, the roofs closest to the sea, chosen for their better orientation and for accumulating more hours of sunshine.
The installation will have a cost of 770,000 euros and the works will last for four months from their start. The project has financing from the European Regional Development Fund, which will assume 40% of the investment.
The energy produced will be primarily for the self-consumption of the Port Authority of Tarragona. When there are surpluses, the facility will inject them into the public distribution grid.
In the execution of the project, the panels will be placed on the decks of the Moll de Costa with a mechanical chemical adhesion system applied directly to the surface. This solution avoids the assembly of previous structures and also eliminates perforations, thereby reducing waterproofing problems.
The Port of Tarragona will use ultralight photovoltaic modules weighing 7.2 kilograms. The difference is relevant in port buildings where the load on the roof conditions the installation, as conventional panels weigh between 18 and 20 kilograms.
With that change, each module reduces the usual load on the structure by 62%. The objective is to guarantee the stability of the buildings and facilitate the placement of the panels on sheds one, two, three, and four.
In addition to the Moll de Costa project, the Port Authority of Tarragona is already reinforcing the roofs of warehouses A, B, and C of Moll de Castella. There it plans to install a 600 kWp photovoltaic plant, the largest in the entire port authority.
In parallel, the port is studying another installation in the vehicle parking lot located next to the administrative building, with a capacity of 200 kWh. If this action and the one at Moll de Castella are added to the new 300 kWp plant and the 750 kWp already operational, the photovoltaic generation of the Port Authority of Tarragona will be close to 2 MW.
