El Hierro fourth quarter 2018 performance update<\/a><\/h3>\n
\n

\"\"In 4Q 2018 Gorona del Viento (GdV) supplied only 27.7 % of El Hierro\u2019s electricity and 6.4% of its total energy consumption, down by a factor of almost three from the 74.2% and 17.1% recorded in 3Q 2018. Since project startup in June 2015 GdV has supplied 45.2.% of El Hierro\u2019s electricity and 10.4% of its energy. During 2018 it supplied 56.6% of El Hierro\u2019s electricity and 13.0% of its energy, up from 46.3% and 10.6% in 2017. Whether this is a result of improved practices or stronger winds in 2018 is unclear at this time. There is an ongoing labor dispute at the Llanos Blancos diesel plant, where workers are demanding more money because their work load has quadrupled since GdV came on line.<\/p>\n

During 4Q 2018 the 11.5 MW wind farm generated a total of 4,053 MWh, representing a capacity factor of 16.0%. But because of inadequate storage coupled with the tendency of the wind to blow in gusts only 64% (2,597 MWh) of this generation was delivered to the grid. The remainder was consumed in uphill pumping. Figure 3 shows total wind generation (wind to grid plus wind to pumping) during the quarter. There is no evidence for any significant curtailment of turbine output. The bimodal distribution of wind generation (either \u201con\u201d or \u201coff\u201d) discussed in the previous report is again evident.<\/p>\n
