Come meet the poster presenters to ask them questions and discuss their work
We would like to invite you to come and see the posters at our upcoming conference. The posters will showcase a diverse range of research topics, and will give delegates an opportunity to engage with the authors and learn more about their work. Whether you are a seasoned researcher or simply curious about the latest developments in your field, we believe that the posters will offer something of interest to everyone. So please join us at the conference and take advantage of this opportunity to learn and engage with your peers in industry and the academic community.
PO362: A Novel Approach to Curtailment Estimation Using Participations Factors and Constraint Programming
Natalia Lapuente, Project Manager, CIRCE Technology Center
Abstract
Curtailment in renewable energy refers to the intentional reduction of renewable energy production when these sources can generate electricity. This phenomenon is usually due to grid constraints, excess supply during periods of low demand, or limitations in energy storage and transmission infrastructure. While curtailment may be a necessary tool for maintaining grid stability, it also represents a significant inefficiency, as it wastes clean, low-cost energy that could otherwise replace fossil fuel generation, as well as presenting a problem for the bottom line of renewable energy. Curtailment is increasingly common worldwide as renewable energy grows. In the UK, nearly 20% of wind energy in the north is unused due to transmission limits. California’s grid (CAISO) curtailed 2.4 TWh of solar and wind in 2022, a 63% rise from 2021, mainly due to transmission constraints. In Latin America, the issue is also escalating Chile saw curtailment reach 9.72% of renewable generation in 2023 and 18.7% in early 2024. Brazil experienced curtailment rates of 10% for wind and 17% for solar in December 2024, with a rising trend [1], [2]. Understanding curtailment risk over a renewable plant’s lifetime is essential for accurate valuation. This requires detailed data on generation potential, grid limitations, and dispatch decisions. To forecast curtailment, advanced modelling and scenario simulations are also needed to estimate its impact effectively. Understanding curtailment is key to optimizing renewable energy investments and accelerating the shift to sustainable energy. It helps identify effective solutions like upgrading the grid, deploying energy storage, and improving forecasting to reduce energy waste and enhance system efficiency. This paper addresses the calculation of curtailment for the Spanish Iberian Peninsula using a method based on the participation [IC1] factors of the different generators in the system.
