Note that the Stationary Energy Storage Failure Incidents table tracks both utility-scale and C&I system failures. It is instructive to compare the number of failure incidents over time against the deployment of BESS. The graph to the right looks at the failure rate per cumulative deployed capacity, up to 12/31/2024.
Stationary Energy Storage Failure Incidents – this table tracks utility-scale and commercial and industrial (C&I) failures. Other Storage Failure Incidents – this table tracks incidents that do not fit the criteria for the first table. This could include failures involving the manufacturing, transportation, storage, and recycling of energy storage.
How energy is produced in power plants—using coal, natural gas, or nuclear power—also affects energy loss. Not all generated energy is converted into usable electricity due to inefficient processes. For instance, fossil fuels convert only about 30% to 45% of their energy into electricity, wasting the rest and increasing greenhouse gas emissions.
Energy loss puts pressure on resources, forcing utilities to produce more power to meet demand. This can overload the electricity grid, compromising reliability. Increasing demand strains the infrastructure, raising operational costs and risking service disruptions.
