Grid-scale energy storage is instrumental in the manner utilities produce and deliver electricity. At present power plants encounter great difficulties in handling load leveling and grid integration of renewable energy sources.
Power plants meet peak demands in an expensive, inefficient, and non-sustainable manner. A robust energy storage technology can shave peak loads and eliminate congestion with excess energy produced by baseload generation during off-peak hours and by tapping onto the renewables during peak generation.
Large cost savings and long-term societal benefits can be achieved as:
