August 2 (Renewables Now) - The smallest of the Canary Islands, El Hierro, supplied itself with 100% renewable energy for more than 18 consecutive days in July, the local government said Thursday.
Starting July 13, 1412 local time, and up to July 31, all of the island’s electricity came from renewables. El Hierro has thus beat its own record from 2018 when the island’s Gorona del Viento wind power-based pumped-hydro system successfully met local demand for 18 days in a row.
Gorona del Viento managed to cover 97% of demand in July, while for the first seven months of the year it produced 51% of the island’s electricity, the local government said. The facility consists of an 11.5-MW wind farm of five turbines which delivers electricity to the hydro storage system. A backup diesel engine is put into operation when neither water nor wind can produce enough to meet the demand.
The power plant is run by Gorona del Viento El Hierro SA, in which the island’s government body El Cabildo de El Hierro holds a 65.82% stake. Spanish power utility Endesa SA (BME:ELE) controls 23.21%, while the Technological Institute of the Canary Islands and the Canary Islands government hold 7.74% and 3.23%, respectively.
Since it started operations in 2015, Gorona del Viento has saved more than 20,000 tonnes of diesel fuel and avoided emissions of some 80,000 tonnes of carbon dioxide (CO2), according to the El Hierro government.
