AI Customer ServiceIn Chile, the curtailment of solar PV has increased significantly in recent years, affecting 1.4TWh of output in 2022 (or roughly 1.8% of annual electricity demand), and nearly 800GWh in the first five months of 2023 (Molina, 2023). In Cyprus, solar PV curtailment has grown from just over 3% in 2022 to over 13% in 2023 (Tsagas, 2024).
Global trends in the curtailment of solar PV In 2018, more than 1% of potential PV output was curtailed in several key markets. Curtailment is driven by PV location, transmission limits, and oversupply. Curtailment follows seasonal patterns and is influenced by policy and grid planning.
As a result, PV output is almost always prioritized over other fuel sources and delivered to the electric grid. However, PV curtailment is increasing as PV composes greater shares of grid capacity. In this paper, we present a novel synthesis of curtailment in four key countries: Chile, China, Germany, and the United States.
Each marginal unit of PV output pushes down the midday net load, making it more likely that PV output will exceed the grid’s ability to absorb that output during the solar peak. As a result, PV curtailment is projected to increase as PV composes greater shares of grid capacity ( Denholm et al., 2015 ).
More PV was curtailed on nodes with higher PV capacity: about 61% of PV curtailment occurred on 10 nodes with relatively high PV penetration. In terms of percentage of potential output, curtailment was relatively evenly distributed across the nodes: curtailment was between 0.1% and 5% of potential output on 66% of the nodes.
As a point of reference, in real power systems, annual average curtailment rates from 2013 to 2018 across the U.S. ISO market areas were approximately 6% for wind and 1.5% for solar.3 Table 2. Summary statistics for the Base scenarios, which are based on least-cost build-outs from the CEM
