National Electricity System (SEN) will add at the end of 2020 the sixth consecutive year with more than 98% of renewable generation, according to data from the Energy Control Center (CENCE). The data comes in a period marked by the pandemic, in which the country’s electricity consumption fell by about 3%.
In preliminary data as of December 15, the SEN’s production with the five clean sources reaches 99.78%. Energy from fuels has been the lowest since 1986; this year it was only 23.73 gigawatt hours. 118 gigawatt hours imported are added to this thermal quota to complete national demand, which has been served by 98.6% with national resources.
In 2020, water – used in plants on edge and with reservoir – continues as the main source within the Costa Rican electricity matrix, with a 71.95% share. The second is geothermal, with 14.90%, followed by wind with 12.39%. On the other hand, biomass and the sun contribute 0.54%.
Facing the beginning of the dry season, the five regulating reservoirs of the Costa Rican Electricity Institute (ICE) show optimal levels. Arenal –the main one that feeds the Arenal, Dengo and Sandillal plants in a cascade– had a year to recover its historical level and now exceeds 541 meters above sea level.
“Faced with the emergency due to the pandemic and the drop in demand, the Costa Rican system has been able to deliver almost all of the energy with clean resources. Despite facing a difficult year, we are making firm progress on the goals of decarbonization and electrification of transportation, ”said Irene Cañas, ICE Executive President
