Since project startup in June 2015 GdV has supplied 46.5% of El Hierro\u2019s electricity and 10.7% of its energy. In 3Q 2018 GdV supplied 100% of El Hierro\u2019s electricity for a total of 45.6 days, with 18 days of continuous 100% generation during a sustained period of high winds from July 15 to August 1. Hydro continued to underperform, contributing only 6.1% of total 3Q generation. According to GdV the plant is now performing at its optimum level but is still not capable of supplying El Hierro with 100% renewable electricity \u2013 an admission of failure. Adding solar panels, enlarging the lower reservoir and EV storage are among the options now being considered.<\/p>\n<p><strong>Performance since project start-up:<\/strong><\/p>\n<p>Figure 1 shows daily mean percent renewables generation since full operations began on June 27, 2015.
