Tesla widening battery booming to gain a foothold in the energy storage market

Hornsdale in south Australia corrientes widening battery to continue rising in the Australian energy market, in the fourth quarter and in the use of frequency and supporting services for $4 million.

Australia dynamic energy market operators in the latest quarter report released the data, the report also shows that the energy storage, especially the transfer time and energy focus on increasing of arbitrage.

in the fourth quarter of data is very remarkable, because from the quarterly data can be seen on the main grid cell number, south Australia increased Dalrymple North cell number, Victoria increased Gannawarra and Ballarat large number of battery.

since 2008, the data also showed in the fourth quarter of pumped storage usage of new records, it shows that as the wind and solar energy shares continue to rise, batteries and pumping system rise in the Numbers, and other forms of storage such as hydrogen and solar heat into the system.

14 months ago since its opening, widening the battery's performance and business model has always been the industry's charm. Tesla, founder and CEO elon & middot; Musk ( Elon Musk） Recently confirmed that $95 million worth of factory may be in a few years to recover the cost.

the actual battery by Neoen Australia owns and operates, every year to pay the $4 million to the south Australia state grid service fee - Due to recent in northern new south wales state after lightning activity continues to alarm status, and therefore the cost increased significantly. This makes all other states to lightening and generator tripping.

tesla also from the FCAS ( Frequency control ancillary services) A profit in the market, at the same time reduce the cost. It effectively destroyed a & other; Cartel & throughout; , it's like pushing prices into the stratosphere of games, and allow Aemo eliminate restrictions brought by the gas generator.

Aemo latest data is particularly interesting. This suggests that the tester is widening battery FCAS income continues to grow rapidly, and from emergency and regulated market for $4. 5 million (FCAS Net) （ Income of $4. 9 million minus the cost of $400000) 。 （ A few could be due to other cells) 。

through professional aggregators EnerNoc demand response has also had the two market share holdings of $3. 5 million. In between the two, the battery accounted for 27% of the market and demand response.

but considering the FCAS market opportunities are limited, it also shows that the energy storage and move the opportunity more and more, may become the most key indicators of the battery.

Aemo pointed out that the peak value of the wholesale market price and the spreads between peak price significantly higher now, and difference of Queensland and new south wales last year almost doubled, to $47 / mw.

but & other; Round trip efficiency & throughout; Means & other; Park spreads throughout the &; , namely the profits of various storage facilities for energy arbitrage is still very low. This is the problem.

in fact, for pumped storage & other; Park spread throughout the &; Is zero, which means that in the process of pumping losses, it is not profitable. Cell ( Mainly hoens dyer, but in a few weeks after this quarter's and other facilities) Created a $20 / mw & other Park spreads throughout the &; , but this is mainly because they are involved in the FCAS market.

it is interesting to note that the battery storage & other; Park spreads throughout the &; In previous quarters significantly improve ( About $36 / mw) , but Aemo said, due to the arrival of the new facilities, it weakened somewhat in the fourth quarter, it is not much competition in the FCAS.

however, the results showed that the battery seems to be more like Hornsdale obtained from the energy arbitrage, this may be due to their response speed and is not affected by the pumping station. Of course, most of their money from the emergency FCAS and regulation.

it is stressed that the introduction of new rules into effect and officially, able to identify several potential value and unlock the battery storage channel before, may be it is difficult to the facility to find the right business model.

advocates and builders for new battery, it will be very attract their attention, for example, in south Australia by Sanjeev Gupta is put forward by the Whyalla Lake Bonney and Lincoln Gap wind farm, and Queensland AGL, and many other potential projects.

due to structure, vector tracking technology to avoid wind damage, reefer procedure, must be considered in the design of reefer motion to control the angular velocity of relative is too big, in the start, especially stop instantly have a far greater than the acceleration of the wind load resistance moment of momentum, and the situation in the sensor under the control of the frequent, make its force under the action of driving mechanism of short-term internal damage, reduce the reliability of the device. This also is in 2006 the Ministry of Science and Technology in the related technical project tracking device can only be levels throughout the life as the operating life of 5000 hours, the elevation Angle tracking mechanism for 2000 hours, and the index with the Carrisa Plains, plant the actual operation situation of no remarkable progress, is the technical index of the low level, no actual value.
