With increased emphasis on reducing emissions from the power sector, grid-level energy storage can enable larger penetration of renewable energy into the grid. Grid-level energy storage is likely to dominate the conversation in the power industry in the coming years, just like renewable energy dominated the conversation in the past 2 decades.

Issues with grid integration of wind energy has led to curtailment of wind power, delay in interconnection for commissioned wind projects and/or denial of generation permit. This report describes the impact of wind power on the grid, methods to analyze the impact and approaches to mitigate the impact.
