The island of La Graciosa is a unique natural site and a biosphere reserve, and is therefore a priority site to become 100% energy-sustainable. It also offers perfect test conditions for incorporating renewable energy into the electricity grid.
The eighth island of the Canaries archipelago doesn't have a single square metre of tarmac, and its energy supply depends on a cable joining the island to Lanzarote. With just over 600 inhabitants, all of whom live from fishing and sustainable tourism, and a total area of 27 square kilometres, La Graciosa is currently undertaking a major electricity innovation, i.e., moving towards a system of self-sufficiency in which it will be possible to generate, store and distribute its own electricity. In addition, it will be a clean, renewable energy. This is the aim of the project set up by a consortium led by Endesa and including the Canaries Technology Institute (ITC), belonging to the Canary Government's Ministry of Employment, Industry and Trade.
The consortium promoting the project is setting up a micronetwork on the island that integrates the distributed generation obtained using photovoltaic panels with batteries and ultracondensors that will help to manage this fluctuating energy. What's more, a wide range of technology (communications, PLC, low and medium voltage automatisms, real time monitoring and control systems, applications for energy efficiency and active demand management) can help integrate the solar energy efficiently into conventional networks.
