PO370: Hybrid repowering strategies for grid-constrained wind farms: Combining over-installation with BESS to reduce curtailment
Chaime Malo, Wind consultant, SÓLIDA, a Bureau Veritas company
Abstract
Much of Europe’s wind fleet is approaching or exceeding 20 years of operation, making repowering essential to sustain renewable energy growth while minimizing new land use and grid infrastructure. This work examines strategies for repowering onshore wind farms in grid-constrained areas by exploring the potential of installing generation capacity beyond existing connection limits. A case study of a wind farm in Galicia, Spain, was developed to assess the techno-economic implications of different repowering scenarios, with a focus on maximizing energy yield and minimizing curtailment. Building on this analysis, the study evaluates the integration of battery energy storage systems (BESS) to increase the value of repowered sites by absorbing curtailed energy, improving market participation, and optimizing revenue streams. Given the variability of wind production, which poses challenges for battery utilization compared to solar PV, advanced operational strategies are considered, including energy arbitrage and grid charging during low-price periods. Simulations were conducted using StoreBrid, an advanced modelling platform that resolves hourly plant operations, accounts for BESS non-linear degradation and evaluates energy balances considering energy markets and different dispatch strategies. The approach combines wind farm repowering simulations, storage sizing analysis, and dispatch optimization to identify the most effective configurations. This integrated methodology provides insights into how battery storage can complement repowered wind farms. Our findings highlight the potential of combining moderate over-installation with a strategically sized BESS to significantly improve asset performance, reduce curtailment, and enhance flexibility. By optimizing both generation and storage investments, this approach addresses the growing need to integrate higher shares of renewable energy without large-scale transmission expansion. The results provide actionable guidance for project developers, policymakers, and investors, contributing to the conversation on how to accelerate Europe’s energy transition by repowering aging wind assets and leveraging hybrid renewable-storage solutions.
