The clean energy trade organisation ACP commissioned a study from Aurora Energy Research, showing a substantial opportunity to enhance grid reliability and reduce energy system costs by deploying large-scale energy storage across MISO.
MISO is the biggest regional transmission organisation (RTO) in the US, covering Arkansas, Illinois, Indiana, Iowa, Kentucky, Louisiana, Michigan, Minnesota, Mississippi, Missouri, Montana, North Dakota, South Dakota, Texas, Wisconsin, and the Canadian province of Manitoba.
According to the report, the RTO is facing a growing load demand that its ageing energy generation resources are not equipped to handle.
Because the large area covered by MISO also has limited transmission infrastructure, there is typically a significant variation in the price of electricity.
The report notes that this summer, MISO saw its capacity prices jump over 2,000%. Without adding energy storage, modelling shows peak electricity prices for consumers will continue to rise and become less reliable over time.
“Without battery storage, modelling shows that peak electricity prices during high-demand hours would be up to US$159 per MWh or higher by 2035. The analysis also estimates that greater reliance on one type of legacy energy infrastructure could add US$493 million in electricity costs. In a future without energy storage, the daily electricity price could spike almost three times higher than if the region builds out energy storage capacity.”
