New energy + energy storage "roll up"! Series energy storage of upper energy group has obvious advantages

Energy storage is one of the hottest tracks at present. New energy policies of many provinces and cities have clearly proposed that new energy projects should be combined with the construction of energy storage system facilities and be connected to the grid at the same time. However, under the pressure of rising material costs and industrial competition, how to help energy storage improve earnings has become a difficult problem.

With the ability to provide excellent products and solutions, Shangneng Electric has been gaining a stronger presence in the energy storage system market recently, especially winning orders from many central state-owned enterprises.

In the past two years, Shangneng Electric has won the new energy distribution energy storage projects or energy storage collection projects of central state-owned enterprises such as China National Nuclear Power Corporation, Huaneng Power Corporation and Pinggao, Xu Ji, Shandong Electric Power Corporation and Baoguang Stock Co., LTD., and has been the energy storage supplier of China National Nuclear Power Corporation for two consecutive years.

Recently, the results of China National Nuclear Group's 2022-2023 new energy distribution storage system were announced. In the face of fierce bidding competition, Shanghai Neng Electric, with its advantages in technology and price, won the first place among 29 bidders and was shortlisted for the contract procurement of 2.7GWh air-cooled energy storage system.

After winning the bid of 300MW/600MWh collective mining at the end of 2021, this is the second time in nearly a year that Shanghai Neng Electric has been shortlisted for large-scale new energy distribution storage collective mining by China National Nuclear Corporation.

Under the strong demand for new energy distribution storage, the energy storage demand of major power generation groups on the new energy side is rapidly rising. Energy storage products of Shangneng Electric have been certified by major central enterprises in price and technology through multi-level evaluation by virtue of their features of small land area, high efficiency, centralized management and easy installation and maintenance, and have highlighted their advantages in energy storage demonstration projects around the country. For example, the 70MW/140MWh energy storage project of Ulanqabu "Source grid Charge and storage" demonstration power station in Inner Mongolia and the 100MW/200MWh Energy storage power station in Qingyun, Shandong Province of Three Gorges Energy have become industry models

As a new energy veteran, Shangneng Electric previously focused on the field of photovoltaic inverters, and its distributed inverters have supplied Huadian, Three Gorges, Jingneng, China Energy Conservation and other photovoltaic power station projects. In 2015, Suneng Electric obtained the first batch of certification of PV leader issued by CQC, and became a benchmark enterprise in the inverter industry.

In accordance with the policy and industry trend, relying on the advantages of inverter products and technology, Shangneng Electric expands its business into the field of energy storage. Different from the photovoltaic business, the energy storage business of Suneng Electric is not only energy storage converters, but further expands it to provide energy storage system integration and overall solutions for the next level of application needs.

Currently, the main product of Shangneng Electric is AC energy storage converter, which covers the full power range of 140kW~3.45MW. It can be applied to photovoltaic + energy storage, independent energy storage, industrial and commercial energy storage and other scenarios.

In addition, the unique series of energy storage converters of Shangneng Electric have attracted more attention from the market. On the one hand, they can effectively improve the power station's revenue, and on the other hand, they can save the initial cost. By realizing the one-to-one accurate management of PCS and battery cluster, the serial-type energy storage converter can ensure that the failure of single cluster battery or single PCS does not affect the normal operation of other devices, and maximize the available capacity of the energy storage system, with the system availability rate reaching more than 99.99%, effectively improving the income of the power station. At the same time, the mode also supports the mix of old and new batteries and recharge by stages, which can reduce the DC side oversupply capacity by 7.0% and greatly reduce the initial investment cost.

Take the world's first 100MW distributed controlled energy storage power station located in Huangtai Power Plant as an example. The installed capacity of this power station is 118MW/212MWh, and it adopts 1500V series energy storage converter and voltage booster integrated machine. Nearly one year after it was put into operation at the end of December 2021, the average charging capacity of the whole station can still reach 208.6MWh. The discharge capacity is 181.9MWh. The latest grid-connected test results show that the efficiency of the power station is up to 87.8%, which once again verifies the technical advantages of the cluster energy storage solution, such as better investment and higher returns.

With the continuous rapid development of the new energy power generation industry and the acceleration of power system reform, the energy storage market breaks out at the same time, and the industry competition becomes increasingly fierce. By constantly improving the research and development and technology of energy storage system, and making continuous efforts in the field of energy storage system integration, Shangneng Electric has repeatedly won large orders and won the favor of the market, achieving a double breakthrough in revenue and reputation.

According to the Energy Storage Industry Research White Paper 2022, Shangneng Electric has won the first place in the ranking of newly installed energy storage converters in 2021. As one of the most high-profile providers of energy storage systems, it remains to be seen what kind of "report card" Shangneng Electric will deliver in 2022.
