Energy Storage Control Capability Expansion: Achieving Better Technoeconomic Benefits at Portland General Electric's Salem Smart Power Center

The value proposition for energy storage systems (ESSs) is a key topic for creating and advancing its acceptance within the electric power sector, particularly for electric utilities. Although ESS as a technology is gaining popularity within the electric utility industry, its anticipated value streams are not fully understood, quantified, and demonstrated. The unavailability of suitable demonstration sites/projects, the lack of a deep understanding of available economic opportunities, and the deployment complexities associated with pursuing those opportunities are some of the reasons that complicate its value demonstration. The lessons learned from holistic demonstration projects covering key steps, e.g., economic value stream identification, evaluation, and its subsequent realization via suitable control strategies, could help electric utilities learn to manage ESS adoption challenges better.
