Spyros Foteinis highlights the acknowledged problem that an insufficient capacity to store energy can result in generated renewable energy being wasted (Nature 632, 29; 2024). But the risks for power-system security of the converse problem — excessive energy storage — have been mostly overlooked.
But the risks for power-system security of the converse problem — excessive energy storage — have been mostly overlooked. China plans to install up to 180 million kilowatts of pumped-storage hydropower capacity by 2030. This is around 3.5 times the current capacity, and equivalent to 8 power plants the size of China’s Three Gorges Dam.
The expansion is driven mainly by local governments and lacks coordination with new energy stations and the power grid. In some regions, a considerable storage oversupply could lead to conflicts in power-dispatch strategies across timescales and jurisdictions, increasing the risk of system instability and large-scale blackouts.
If the grid has a very high load for eight hours and the storage only has a 6-hour duration, the storage system cannot be at full capacity for eight hours. So, its ELCC and its contribution will only be a fraction of its rated power capacity. An energy storage system capable of serving long durations could be used for short durations, too.
One of the advantages of oversizing an energy storage project upfront is that it won’t have to be shut down for weeks or months, either wholly or partly, for construction later. Doing it at the onset of the project eliminates the need for site mobilization, permits, labor and commissioning of the new section of the plant.
The situation is further complicated by electrochemical-energy storage stations that operate at different voltage levels, hindering the suppression of fluctuations caused by inherently variable energy sources, such as wind and sunlight. Expansion of the capacity to generate energy must align with the capacity to store it.
