The new economics of energy storage | McKinsey
Our research shows considerable near-term potential for stationary energy storage. One reason for this is that costs are falling and could be $200 per kilowatt-hour in 2020, half today''s price, and $160 per kilowatt
Why Is Energy Storage So Important? Green Energy
One of the key reasons energy storage is important is that it enables the integration of renewable energy sources such as solar and wind power into the electricity grid. Renewable energy sources are intermittent and

Electrical energy storage (EES) cannot possibly address all of these matters. However, energy storage does offer a well-established approach for improving grid reliability and utilization. With so many potential financial
6 FAQs about [Reasons for electrical energy storage]
Why is energy storage important?
As the report details, energy storage is a key component in making renewable energy sources, like wind and solar, financially and logistically viable at the scales needed to decarbonize our power grid and combat climate change.
What is energy storage?
Energy storage is a technology that holds energy at one time so it can be used at another time. Building more energy storage allows renewable energy sources like wind and solar to power more of our electric grid.
How will storage technology affect electricity systems?
Because storage technologies will have the ability to substitute for or complement essentially all other elements of a power system, including generation, transmission, and demand response, these tools will be critical to electricity system designers, operators, and regulators in the future.
Does energy storage provide backup power?
Energy storage can provide backup power during disruptions. The same concept that applies to backup power for an individual device (e.g., a smoke alarm that plugs into a home but also has battery backup), can be scaled up to an entire building or even the grid at large.
Does storage reduce electricity cost?
Storage can reduce the cost of electricity for developing country economies while providing local and global environmental benefits. Lower storage costs increase both electricity cost savings and environmental benefits.
How does energy storage work?
Pumped hydroelectricity, the most common form of large-scale energy storage, uses excess energy to pump water uphill, then releases the water later to turn a turbine and make electricity. Compressed air energy storage works similarly, but by pressurizing air instead of water.
