the one chart to show you the future of grid energy storage - commercial energy storage systems
5 installed in the United States.
According to a report released by the GTM Research and Energy Storage Association on Thursday, the 8 MW energy storage system in the first quarter of this year, an increase of 16% over the same period a year ago.
These energy storage systems are mainly lithium.
Ion batteries, types that can be found in consumer electronics and electric vehicles.
Because they are already in mass production, they have become the technology of choice.
Even so, lithium
From an absolute point of view, ion batteries are still expensive compared to the current electricity bill for most people. A lithium-
An ion system for a home or business can run thousands or tens of thousands of dollars.
SolarCity sells 10 KW-
Tesla cars produce hourly Systems for $7,140, including all equipment and installations.
It also offers 9-
Provide customers who want energy storage and solar panels with an annual lease for the same system.
$5,000 in advance for battery system rental.
Energy storage current makes more sense for businesses because utilities typically charge a "demand fee" to help ensure they have enough power generation at hand to meet their needs.
Electricity demand for commercial and industrial operations may change more than for families.
In a few hours of high energy demand, demand costs can change, often much higher, and they can account for 50% of the company's monthly bills.
Then, it might make more sense for a business to install a battery system, when the rate is low, it stores electricity, and when the rate is high, it discharges energy for on-site use.
This economy is not so attractive for families, so energy storage is sold primarily as a backup power supply.
The energy storage market is still very young, and most of the equipment installed today is not at home or in the enterprise.
In fact, the installation of 72%, or 4.
Installation of 2 MW in the first quarter directly helps utilities or grid operators maintain proper voltage and supply and demand for the grid.
These items are often called "pre-meter" installations.
However, Ravi Manghani said that by 2018, more energy storage systems will land in homes and businesses rather than in front of electricity meters, including government buildings and universities, instead of those senior energy storage analysts and lead authors who specialize in the report.
Between these two segments, commercial projects could account for 60% of the installation by then, while residential systems account for the rest.
