6 FAQs about [Insufficient energy storage system capacity]

Is excessive energy storage a problem?

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.

What happens if the energy storage system is less than zero?

If is less than zero, first consider charging the energy storage system, then consider selling the remaining electricity to the external power grid. If is less than zero, the energy storage system is first considered to be charged, and the remaining electricity is considered to be sold to the external power grid.

Is storage ESS economically viable?

Economics of storage ESS are gaining significance within the contemporary energy domain, encompassing various utilities such as grid stabilization and the integration of renewable energy sources. The economic viability of these systems, however, remains a key concern for their widespread adoption.

Is excessive energy storage a threat to China's power system?

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.

Can energy storage capacity be allocated based on electricity prices?

Conclusions This article studies the allocation of energy storage capacity considering electricity prices and on-site consumption of new energy in wind and solar energy storage systems. A nested two-layer optimization model is constructed, and the following conclusions are drawn:

Why is energy storage oversupply a problem?

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.
