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
