In 2019 the United States energy storage system capacity up to 712 mw

Solar photovoltaic net news: according to IHS Markit survey research organization, the United States this year will become the world's largest grid energy storage market, thanks to the photovoltaic (pv) + energy storage projects increase capacity deployment and peak demand.

grid storage system deployed in the United States this year is expected to reach 712 mw of installed capacity, is almost twice the 376 mw in 2018. This will help us beyond the South Korea and South Korea this year storage capacity deployment could sharply dropped to below 600 mw.

in 2019, the U. S. energy storage market strong compared with 2018, there will be a complete transformation, when the energy storage deployment stagnate, South Korea's energy storage deployment of rapid development. In 2018 South Korea have set new records, grid energy storage market and global energy storage capacity almost doubled last year, this is mainly by the energy storage market rapid growth in the first half of 2018. Last year, however, the market is growing slower, energy storage deployment rose only 22%.

牛; The federal policy ( Such as the federal energy regulatory commission's 841th order) Is driving across the country, regional power grid operators include additional market mechanism, makes more energy storage resources to participate in the activities of wholesale market.

牛; At present can be used in solar investment tax credit ( ITC) Is driving the rapid growth of photovoltaic (pv) grid scale + energy storage project development, especially in the western United States.

牛; State energy storage tasks and incentives are promote the development of energy storage market, the market is also struggling to cope with a relatively high level of renewable energy penetration.

牛; Utility company is stepping up to the user side and grid side energy storage resources procurement efforts, with integration of higher levels of renewable energy, and provide additional power grid service, such as demand response.

IHS Markit estimates that from 2019 to 2023, the United States will have installed capacity of more than 2 gw solar energy storage system with the grid scale ( PV) Form a complete set of system deployment. Investment tax credit ( ITC) Combined with solar farms energy storage system to promote the development in the market over the past year, and will become the power grid scale solar energy and energy storage colocation deployment of the main driving force. Most of these systems is expected to be deployed in the western United States market, including Hawaii, California, Arizona, thus make solar power a further consolidation in the relatively saturated markets.

as for the installation of solar power capacity, is expected from 2019 to 2023, the installed capacity of 10 gw of power grid scale solar power generation facilities will be deployed, and energy storage system of the power grid scale solar power generation facilities during deployment of 16%.

according to the size of the energy storage system and the characteristics of dc coupling system and the exchange coupling system, compared with a significant cost advantages, the main advantage is to reduce the required power conversion equipment, and direct current (dc) can be acquired by other means. Although ac coupling system is more flexible to participate in a wider auxiliary service, but the two types of systems can use investment tax credit ( ITC) Policy and benefit from sharing installation and operating costs.

IHS Markit, estimates that 2019 to 100 mw ac single axis tracking solar system deployment of 25 mw / 100 MWH energy storage system, if there is no investment tax credit ( ITC) , which may increase the cost. Assuming that in 15 years to replace the battery energy storage system, can reduce energy consumption of 35% to 40%. Considering the dc coupling system installation and operation of synergy, and the investment tax credit ( ITC) Used in solar power generation and energy storage system is deployed, can realize the leveling of less than $40 / MWh energy costs ( LCOE) 。

IHS Markit predicts that by 2023, the United States of photovoltaic (pv) + energy storage projects will be can be fierce competition with natural gas plants resource to generate electricity.
