Why is the reason why Germany's large energy storage facilities deployed?

As of the end of 2019, Germany has installed about 2.1GWH batteries in family, business and industrial facilities and large-scale grid-connected applications. According to the results of Accure collected and analyzed by RWTHAACHENUNIVERSITY Juli Research Group and Battery Expert Group, although the family energy storage market and the industrial sector grow up last year, it is expected to continue to grow, but the large energy storage market slows down, 2019 During the year, the country only deployed 9 projects.

The economy is a challenge for large projects in 2018. There are 22 large projects (> 1MW rated or> 1MWH capacity). The slowdown in the size of the grid is mainly due to battery owners and investors from providing frequency control reserves (FCR) to decline.

The research team pointed out that FCR is almost the only financing source of large-scale energy storage in Germany, which means that the saturation of the market makes the economy more challenging. In other words, it can be said that the battery is a victim of its own success, because the battery can quickly and efficiently provide a crucial grid balance service, and subsequent FCR auction is lowered. The market has risen quickly, as of the end of 2019, the accumulated installation of 68 projects, accumulated power generation 400 MW, power generation 620 MW.

New 9 projects in 2019 Total 54MW / 62MWH. Research thesis "The Development of German Fixed Battery Storage System - The Status of 2020" said that the price from 1500 Euro / Tree (1212 USD) last year, this makes the market "for new participation More and more attractive. However, some hopeful development is about to appear in the short term.

Earlier this year, German grid regulatory Bundesnetzagentur approved the proposal for the establishment of a so-called "virtual transmission line" proposed by the grid company, which is a large project called GridBooster. This article is pointed out that this should include two 100mW / 100mWh items and a 250mW / 250mWh project to provide redundancy and spare capacity for large power transmission lines. These projects are expected to operate in 2022, which will save large capital and longer development cycles for transmission network operators, rather than building traditional transmission system infrastructure.

They will also provide some improvements to the market prospects of large industries, and increase the accumulated power generation to 450 megawatts / 450 megawatts. In France, a small set of pilot projects is planning along a similar concept line. The "renewenergyfacilities" recently launched "RenewenergyFacilities will also promote the development of large systems, and leave some capacity for solar or wind energy projects and energy storage projects.

Recently, these tenders have been described as less active aspects of the German government reforming renewable energy law plan. With the decline in the price of residential and industrial sectors, economic growth is still in the total installation amount of 2.1 kWh mainly by small residential system.

In 2019, about 60,000 domestic battery storage systems were sold and installed, with a total of 250MW / 490MWH. At present, there are about 185,000 such systems in Germany, and the researchers said that there is approximately 750MW / 1420MWH. In every field in the German market, lithium-ion batteries are the most popular battery chemistry options.

According to the report, due to the low battery power of the medium system to 700 euros per kilowatt, the average price is about 1100 euros per kilowatt, including the power electronics of the system of 5 kWh to 10 kWh, so small and medium storage pricing has Very good transparency. Many homeowners who choose battery energy are also selecting hot pumps and other related products. The motivation of purchasing home storage systems is mainly focused on "pairing price" or personal hopes to play their own roles in the process of cleaning and renewable energy.

According to the registered database created by the German Federal Network Bureau, from the end of 2019 to early May this year, approximately 20,000 new system registrations. Finally, commercial and industrial (C & I) has grown up last year, with a fairly small starting point, although it is difficult to obtain confirmed public data on installation so far, the register of the Federal Network Bureau shows that since the opening of the register since 2019 Added 700 industrial storage systems (greater than 30 kWh to 1 MW). This is equivalent to cumulative installation of approximately 27MW / 57MWH.

Researchers and analysts pointed out that the energy storage market is expected to grow. In Germany, industrial storage has a range of available cases, through these cases, energy storage system users can save money or make money. These measures include peak, renewable energy self-consumption and buffer electric vehicle (EV) charging solutions to avoid pressure on the grid.
