How much does energy storage cost?

Calculated by Guotai Junan Securities in October 2013. The target cost for the marketization of energy storage industry was about 200 dollars/kW h, equivalent to 1246 yuan/kW·h. However, at present, the cost of PbAB is about 1000 yuan/kW·h and the cost of NaS battery, LIB is about 4000 yuan/kW·h.

Why is energy storage industry in China a big problem?

Judging from the present condition, cost problem is the main barrier. And the high performance and high security of the relative technology still need to be improved. Until 2020, energy storage industry in China may not be spread massively and the key point during this period is the technology research .

What is the energy storage system?

The energy storage system includes 1×5 MW×2 h LiB, 1×2 MW×2 h VRFB. And the wind power of 99 MW had been put into operation in August 2012. The system is connected with the 35 kV bus. Through intelligent control, the system stores and releases power according to the coordinating with wind power.

How to improve energy storage technology?

First of all, quicken the pace of establishing basic standards and revising the existing standards. Technology standards, design specifications and other requirements are of the basic standards of energy storage technologies. At present, some relevant standards for corporations and industry have been established and published.

Is abandoning wind power more economical than energy storage?

In WSST Project, the average charge-discharge cost of LiB is about 1.5 yuan/kW·h each time which is higher than the peak power price. Therefore, abandoning wind power is more economical than equipping with energy storage system. In fact, energy storage is now still at the stage of demonstration, the earnings are little . 3.2.

How to improve the commercialization of energy storage industry in China?

The above problems have constrained the commercialization of energy storage industry in China. Therefore, we should take relevant measures, including reducing costs by all means, perfecting technical standards, establishing advanced benefits assessment system, and improving relevant incentive policies. 4.1. Reduce costs by all means
