Chile | SIC+SING Interconection
It’s been exactly two years since Chile got its two main electrical systems (SIC and SING) interconnected! Among other benefits, this first interconnection milestone (which was then completed by the Cardones – Polpaico 500 kV completion, in several phases) allowed to drastically reduce #curtailment levels for #wind and #solar power plants. This occurred gradually, as the lines were increasing their operational capacity: in October 2017, the overall (wind + solar) curtailment rate reached its maximum with 22%, and then decreased to 5% in October 2018 and 1% in October 2019. #renewable #transmission #energymarket
