Renewable Energy Curtailment 101: The Problem That''s Actually

Renewable energy curtailment in the CAISO has steadily increased over the past few years as California adds more wind and solar to the grid. However, only 2% of total solar energy in the CAISO was curtailed in 2018, and the CAISO expects only 3-4% of total solar energy to be curtailed in 2019. (The vast majority of curtailed energy is from solar, not wind.)

Curtailment of renewable generation: Economic optimality and incentives

The main argument is that it is a loss of green energy and an economic loss to curtail generation with near zero marginal costs. However, this view could lead to overinvestment in grid infrastructure and underinvestment in renewable energy sources. This article argues that some curtailment of fluctuating (variable) generation is optimal.
