Over the next 10 years, the global power sector will undergo dramatic changes in its technical and business profiles. As generation resources evolve – both with and without carbon constraints – load profiles will grow and become increasingly more dynamic. These changes will necessitate an adaptive flexibility from system infrastructure, generation resources, and load. To manage these changes and prepare for future innovation, utilities, grid operators, and service providers are developing strategies that enhance grid flexibility, incorporate carbon-free generation resources, and accommodate growing electricity demand. What role advanced batteries will play in these strategies remains uncertain.
