Global 10 energy storage policy case analysis

Energy storage development goals is by far the most common policy mechanism, California and other parts of the United States, South Korea and other regions have implemented a similar policy. It focuses on regional energy storage market development direction, and not cover specific purchasing target ( Purchasing target usually will be confirmed in the subsequent policy) 。

more complex policy is an attempt to help energy storage to participate in the electricity market operation. These policies in FM ancillary services as the goal, such as the United States the PJM market service and the advanced frequency modulation (FM EFR） Service. Scope of this kind of policy is currently expanding: the federal energy regulatory commission decree no. 841 ( FERC841） Asked the United States of the wholesale electricity market to store the technical characteristic is taken into account in market operation, and ensure that energy storage technology can be involved in all services.

increasingly stringent power system flexibility demand is the main driving factor of energy storage policy. As the renewable energy power generation proportion is more and more big, the traditional flexible forms of power generation, such as coal and natural gas plants are gradually withdraw from parts of the market. Energy storage system is increasingly becoming an important source of electric power system flexibility, and will contribute to the permeability of the global wind energy and solar energy project from the current 7% to 50% in 2050.

to promote the development of local related manufacturing is one of the main driving factors. Represented by South Korea, the country's policy will support the samsung and LG chemical enterprise become a global leader in the field of energy storage battery. The Japanese government, the federal government and U. S. states government provides capital for the development of domestic energy storage company.

at present, the energy storage application for the impact of electric power market is very limited. But as the energy storage capacity is increasing, its influence on power market will also increase. Energy storage technology will be used to meet the demand of the peak load, change the way the use of fossil fuel power plants, and balance the wholesale electricity market price, at the same time improve the profitability of renewable energy projects. Large-scale deployment of energy storage project will pose a threat to the future of fossil fuel power plants income. But for now, the impact of energy storage applications are limited in the relatively small auxiliary service market.

in general, the application of energy storage technology to underestimate the policy choice and the complexity of the market reaction. Market participants for each policy and every market reaction there are significant differences, but the reaction depends on the specific interests and profit opportunities.

transmission operators Terna conducted 48 mw / 253 MWH of battery energy storage demonstration project is up and running, in order to test its ability to provide FM and load tracking service. Although have had mixed results, demonstration projects for power system operator and battery supplier provided valuable experience, drive to start deploying energy storage projects elsewhere in Europe.

since 2011, the Korean government began to implement a 500 mw FM storage purchase plan. Driven by the regulation, South Korea has built a total capacity of 324 mw of energy storage projects. Photovoltaic (pv) - in addition, South Korea The wind - Energy storage hybrid power generation project certificate issued by a large number of renewable energy is also promote the construction of the three. 2GW/7. 6 GWH storage project.

since 2012 by the tariff policy led to Hokkaido ( Hokkaido） And Okinawa ( Okinawa） The rapid development of photovoltaic power generation. To this end, the local utility company requirements photovoltaic power station installation of storage systems provide renewable energy power generation system of climbing ability. Although the policy launch triggered energy storage has realized the scale of the application, but also to renewable energy project developers have come at a high cost.

in order to promote energy storage participation, operator, Britain's electricity system The British national grid ( 国家电网) The reform of the frequency modulation and the capacity of the market. Although the regulatory reform for the future development of energy storage create uncertainty, but the bidding mechanism of the past brought British FM and capacity of 900 mw of energy storage requirements.

the federal energy regulatory commission ( FERC） Released the 841 act, requires all electricity wholesale market in the United States must make adjustments to their rules, in order to increase the application of energy storage in electric power market, and paying attention to the physical and technical features of the storage into the rules of market operation thoughts. This is by far the most widely range, support for energy storage applications of electricity market rules, making energy storage with the existing power generation mode in the same market competition.

California: in 2013, against the state of California investors held by utility companies ( IOU） Set 1. 3 gw of energy storage project procurement objectives. In 2016, after a goal on the basis of an increase of 500 mw. The final purchase size will be more than 1. 9GW。 The IOU is expected before the prescribed period in 2024 to meet the target, and ultimately purchase scale will exceed the previous targets.

in other parts of the United States: New York, Massachusetts, New Jersey and Oregon and Arizona, has been published or are working on the corresponding energy storage development goals. According to the published target, total will be completed at least five states before 2030 gw + 1 GWH energy storage projects. In addition, California and Massachusetts are formulated by the related standards of clean energy to meet peak loads ( 清洁标准峰值) 。 This standard will be further drive the energy storage in the two states policy mechanism of large-scale application.
