Energy storage market or will double over the next two years

Solar photovoltaic (pv) net news: due to the deployment utility scale energy storage in the fourth quarter of 2018 strong growth, energy storage industry achieved record growth in 2018.

but compared to the future, the growth will be overshadowed: research expects the energy storage capacity will be doubled in 2019, 2020 will be increased by 2 times. Such growth would promote energy storage projects from pilot scale to all parts of the country's power grid planning.

according to Wood Mackenzie, the company's latest energy storage energy research institutions deploy monitoring report, in 2018 the United States to deploy the battery energy storage system of the total capacity of 311 mw / 777 MWH.

in residential energy storage system and commercial energy storage system, the overall deployment capacity more than in the past four quarters commend utility scale energy storage. In the fourth quarter but also for the development of the record. Grid size hit a record quarterly deployment of energy storage capacity of the energy storage system.

advanced energy storage, an analyst at Wood Mackenzie, the company, the study's author Daniel Finn - Foley, said this was recorded in the process of normal business, this indicates that the industry is diverse, and more mature.

芬恩- Foley said, & other; This is not a surprise quarterly growth, this is we have been focusing on market development direction of natural evolution, finally beginning to now. ”

although California and PJM market still dominate the energy storage deployment of the total capacity, but the quarter energy storage deployment of regional scope of its activities in growing. Finn- Foley, points out that in Hawaii, California, Texas and Minnesota, Colorado, the deployment of business model of large energy storage projects have been launched at the end, the vigorous development of residential energy storage market sent some mixed signals.

residential energy storage projects in the first quarter and the second quarter of the energy storage capacity of more than the size of the business or utility scale energy storage projects. Overall in 2018 than in 2017 increased by 350%, deployed nearly 15000 home energy storage system.

but the deployment of growth in the residential energy storage system for six consecutive quarter of record in the third quarter of 2018 is terminated, the fourth quarter than in the third quarter fell. The expert points out, energy storage product availability is probably one of the key limiting factor. Even families with one of the most popular tesla battery system, can't timely delivery, only a few company won a large market share.

business sector development mixed energy storage project quarter, however, deployment is very popular in the fourth quarter, a record 30. 5MW/78. 2MWh。 The results make the business sector to achieve 53% growth in 2017.

the biggest milestone is still the federal energy policy level adjustment committee ( FERC） Order no. 841, the orders of regional wholesale market operators according to its unique properties ( Such as charge and discharge) Energy storage system how to participate in the market.

芬恩- Foley says, independent system operator and regional transmission operators at the end of last year submitted their plans, final implementation should come before the end of 2019. There are some important problems need to be solved, such as how to manage energy storage systems to participate in the retail and wholesale market.

he warns that the arrival of the order no. 841 May not create any new, one-time business opportunities. On the contrary, it is for developers have tried in the early market provides a better definition of a series of cases.

in February this year, utilities plan calls for Puerto Rico in the first four years, to increase the energy storage project of installed capacity to 440 MW and 900 MW. Arizona public service, by 2025, the deployment of 850 mw of energy storage devices, it is the early use of energy storage technology a great progress.

in January this year, the Hawaiian electric company asked regulators approve a series of power purchase agreement, this will allow Hawaii increase installed capacity of 1048 mw of power grid.

芬恩- Foley said, & other; All this is to confirm the value, utility companies are now in identifying the forefront of energy storage system value, and they will choose the energy storage system. ”

, he points out, these factors make Wood Mackenzie company, five years of accumulated energy storage forecast an increase of 9% last quarter.

photovoltaic according to a recent policy discussion as a result, photovoltaic construction scale is not less than 2018; this year And, in & other; Policy to return to the market & throughout; The backdrop, in addition to the household, poverty alleviation, photovoltaic (pv) from the fixed feed-in tariff to the comprehensive competitive era. The local government & other; From the past independent distribution index became a coach and manager, in the province to lead the development of the province enterprises to carry out the national grand meeting. ” So, to support the development of the photovoltaic (pv), will launch
