Electrical storage is done on a large scale in this country by generating companies. They use these storage sites to deal with the fact that energy demand is higher at peak times (Weekday mornings during factory startup, etc..). Energy storage ranges from potential to chemical energy storage. Energy storage involves lots of loss.
One popular solution is the 'reverse hydroelectric' reservoir. Water is pumped up a hill with the electricity, and when demand peaks, it flows back down through a generating turbine. Compressed air storage in large caverns is also used, but mostly experimentally. Large scale batteries (Sodium cells) are under research.
