Tesla installed in Osaka, Japan, Asia's largest energy storage system

At the end of March 2019, tesla energy storage in Japan, for the kinki Japanese railway ( Nearly iron) Install 7000 KWH in Osaka storage capacity of the emergency standby equipment of power system. The system should be completed by April 1, 2019, is Asia's largest energy storage systems, installation only took 2 days.

if the past grid and electricity distribution lines hurt by disasters or accidents, for example, often can only let passengers get off in the middle of the railway train, the railway company staff under the guidance of walk all the way along the railway to the station, very dangerous. With redundant device, can safe driving to the next stop to let passengers get off.

the system consists of 42 tesla Powerpack industrial grade of battery energy storage device, the total storage capacity of 7000 degrees, sufficient iron train for nearly 30 minutes.

except as a redundant power in peacetime, the energy storage system can also be used as a function of transfer peak electricity, electricity peak in Osaka, the time of the power supply tight, almost from the battery energy storage system electric iron, reduce the load of power grid.

it is lithium battery energy storage system is not suitable for long time storage, made as a redundant power application is quite limited, on the development of hospital to establish a redundant power, for example, consider if it is a typhoon disasters such as earthquakes, interruption of power grid could last for several days, and hospital equipment requires constant power supply and demand for such a long time, the current mainstream is given priority to with diesel generators.

however, rail system condition is different, as long as the beginning of the power, can continue to operate, can let the train safety driving to the next stop, after the evacuation of passengers, so the railway energy storage requirements within 1 hour, lithium battery energy storage system can easily do.

in addition to Japan, Italy's national electric power company (previously Enel) Also try to launch a special lithium battery energy storage device into traffic areas, used to assist the Russian railway company ( 俄罗斯铁路) Capacity of ascension.

tesla for nearly iron of this system, completed to become Asia's largest energy storage system at present, at present, the world's largest energy storage system is build tesla, namely in Australia to set up the storage capacity of 100000 KWH system.

tesla in July 2018 to obtain other California Pacific mw electric power company ( PG& E) The contract to build unit capacity of 182. 5 million watts, storage capacity of 730000 kilowatt-hours of energy storage system, to replace the peak gas power plant, if completed will surpass the size of the Australian system become a new system of the world's largest.

in 2018 tesla installation of energy storage system a total storage capacity of 104 million degrees, is three times as many as 2018, a multiple growth is quite remarkable.

but tesla said, this is the result of the limited battery supply in 2018. Remove the battery supply bottlenecks, optimistic size can easily reach 200 million degrees, 2019 and it also can improve profitability, musk himself said: obviously large-scale energy storage system for tesla has a huge market opportunity.

lithium battery prices continue to fall is a major economic power to promote the business opportunities, musk, said if the cost of storage capacity, in 2018 tesla battery core itself, the cost is below $100 per kilowatt-hour of integer, musk has overpromised, said in 2019, together with the battery modules can cost less than $100 per kilowatt-hour.

bloomberg new energy finance according to the analysis of the global more than 7000 project instance, found that the homogenization of lithium-ion batteries cost ( Note) Since 2018, plunged 35% in the first half of the year. Bloomberg calculations, homogenization of energy storage cost to 0 per kilowatt-hour. $187, which is lower than the peak electricity prices in many areas. This means that the energy storage to peak power supply has begun to have economic benefits.

great energy ( Xcel能源) In August 2018 to eliminate the Pueblo, Colorado county, become a total generating capacity of 660 million megawatts coal-fired power plants, renewable energy with energy storage to replace, including 1. 131 gigawatts of wind, 707 million megawatts of solar energy, tie-in 275 million watts of battery energy storage, $2. 5 billion total budget, remarkable energy estimate such replacement, Colorado, will be able to save 2 taxpayers. $1. 3 billion to 3. 7. 4 billion dollars.

but remarkable energy itself still have profit space, because great energy for power suppliers bid in 2018, the Colorado clean energy projects, under the wind power price 0 per kilowatt-hour. 011-0. 018 dollars, pure solar price 0 per kilowatt-hour. 023-0. 027 dollars, and solar hybrid energy storage was priced at 0 per kilowatt-hour. 03 ~ 0. Between the 032 dollars.

show remarkable energy standard case, used to think that energy storage with renewable energy will make cost exploded views have been out of date, the renewable energy itself, and a decline in lithium battery costs double contrast, the renewable energy composite energy storage has been available in the economy, and so is tie-in, to the power grid scheduling ability and the ability of resistance to natural disasters and accidents are much better, this is perhaps tesla confident reason for energy storage market.
