Endesa has put forward proposals to decarbonise Spain’s island territories by 2040 – ten years ahead of the emission reduction targets set by the European Union and by Spain for 2050.

The Spanish utility has published a study, carried out in conjunction with Deloitte, indicating that decarbonization of the Canary Islands, the Balearic Islands and the Autonomous Cities of Ceuta and Melilla, could be achieved with an investment of € 30 000 million. The investment would add 16 GW of renewable energy capacity to the grid as well as 39 GWh of energy storage.

It would also reduce household energy expenditure by 72 per cent, and generate up to 90 000 jobs, Endesa said. According to the report, the Balearic Islands would need to install 1.7-1.8 GW of additional renewables capacity to the current 100 MW by 2030 and a further 2.8-3.2 GW in the following decade to help meet an expected three per cent/year increase in electricity demand to about 12 TWh in 2040. Total renewable capacity would reach 4.5-5.0 GW by the end of the plan.

By 2030, the new renewables capacity would be about 90 per cent solar PV and cover a targeted 70 per cent of power demand with the help of demand management and an initial 2 GWh of batteries. The roadmap for the Canary Islands includes ramping up renewables capacity to 10-11 GW in 2040 from about 600 MW currently, with a wind-to-solar ratio of 25:75. It also includes 20-25 GWh of batteries. Decarbonising Spain’s island territories would also bring experience in the deployment of new technologies, Endesa said.
