Shared consumption

Energy islands, self-sufficient and with surplus

In 2020, various pilot tests of shared consumption energy communities were launched between various concessionaire facilities. The goal is to make the most of photovoltaic generation, ensuring that the surplus produced in one facility can be used by neighbouring ones.

An energy island is a model that is committed to self-sufficiency, both in the generation of energy, and in its consumption and storage. It reduces dependence on the distribution network and requires less energy transport and, therefore, reduces losses. All energy consumed locally is energy efficient.

The project includes La Llotja, the ice factory and other facilities, such as parking lots and restaurants. First, the distribution of energy consumption over time is identified and monitored. The Port of Barcelona is located in an open-plan, well-oriented area that receives sunlight practically 365 days a year, so photovoltaic energy is the most appropriate. 

Panels have been installed on the roofs of the buildings and on the pergolas. Once consumers and generators of this energy have been identified, a simulation and matching exercise is carried out that results in some conclusions that show what the self-consumption percentage is and what the equivalent price is of kilowatt/hour generated by the different actors. From here, the investment and exploitation of the energy community is dimensioned.

This is achieved with energy storage in batteries and sensorising the electrical network so that it is intelligent and can decide at all times the best destination of the electricity produced.
