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:

• Infrastructure optimization by reduced cost in new infrastructure deployment and maximizing the existing grid assets
• Energy arbitrage by minimization the use of or complete replacement of high-emitters gas-fired peak generation.
• Reduce CO₂ emissions by facilitating a wide penetration of renewables
• Alleviate the strain on congested locations and mitigating costs on transmission and distribution systems.
