A better storage dispatch approach could reduce production costs by 4 %–14 %.

Expansion of the capacity to generate energy must align with the capacity to store it. Plans for both must also integrate power-grid improvements, and power-dispatch authorities should have a bigger part in developing the overall strategy. Nature 633, 286 (2024)
The main drawback to this approach is that the MT production cost, storage dispatch or stochastic models may not accurately represent power system details (transmission constraints, operating reserves, ramp constraints, etc.) which could impact the deployment and operation of energy storage technologies.
