La Gomera is the third smallest island of the Canary Archipelago (Spain). It has 64 dispersed populational nuclei, a 21 MW thermal power station (diesel) and a 20 kV distribution network. Instead of proposing a centralised (renewable) electricity generation model for the decarbonisation of the island, like it has been done on El Hierro with its successful Wind – Pumped Hydro Storage Power Station, the roadmap for La Gomera´s transition to 100% renewable energy is based on a distributed generation approach.
Besides ongoing private sector initiatives, the current plan (“100% sustainable La Gomera”) promoted by the public authorities and the technological partner ITC consists in a combination of intelligent selfconsumption, innovative hybrid systems and microgrids (that are to be integrated as “energy communities”), which are being located at emblematic sites for further replication.
The challenge of integrating distributed renewable energies, especially in island systems, must be overcome by trying to generate new business models, encouraging the participation of citizens and, on the other hand, providing the distributed generation systems of capacities that allow support in the operation of the electrical networks to which they are connected.
6 pilot projects are being carried out by ITC. Two of them are almost completed:
