Hybrid power generation systems integrate renewable electricity generation with energy storage as a grid asset. However, the path to an optimal technology balance can be complex and very project-specific. Developers of these projects must navigate through a wide variety of locational criteria and technology options to achieve a best-fit design and operational strategy. This session will review the current market and development trends in wind, solar and energy storage technology; then discuss the advantages, technical considerations and future implications for the addition of battery energy storage to solar and wind-based renewable power generation projects.
