Energy storage technologies have the potential to provide grid flexibility as the cost of these technologies has declined rapidly during the last decade. At the same time, grid flexibility is becoming increasingly important with the increasing renewable energy integration across the world.
Analyzing energy generation data, the study concluded that energy storage requirements for a wind and solar-only grid were high and would need to increase further to cover the total energy demand of a country without combustion fuels.
Grid-connected storage refers to storage that is connected to a centralized power system. This report is focused on grid-connected storage. For more information, check out the USAID Grid-Scale Energy Storage Technologies Primer. Higher penetrations of VRE (Variable Renewable Energy) can drive additional need for power system flexibility.
We find that energy storage mandates largely reduce the variability in electricity prices, especially for the first 20 TWh of mandates (Fig. 6a). In the 1.94 TWh baseline, 82% of the marginal prices are at 0 $/MWh since for large portions of the year the WECC generates more renewable energy than it needs.
Energy and power capacity of candidate storage plants are unconstrained and optimized by the model from the perspective of the grid, such that the model may build storage of any duration and size in each load zone.
Energy storage has the potential to play a crucial role in the future of the power sector. However, significant research and development efforts are needed to improve storage technologies, reduce costs, and increase efficiency.
