Storage Grid News: According to the observation of energy storage and power market, the total compensation cost of AGC FM auxiliary service in Shandong Province rose rapidly after entering the power spot market, and has been maintained at a high level.
In January this year, Shandong FM compensation exceeded 100 million yuan for the first time, reaching 102 million yuan. The continuous operation data in 2022 shows that the skyrocketing trend of AGC FM auxiliary service compensation in Shandong is not a flash in the pan. From January to August, more than 5 months 'compensation exceeded 100 million yuan, and in July 2022, it once reached 200 million yuan.
From January to August 2022, the average monthly compensation of AGC FM in Shandong Province was 11.01 million yuan, which increased by 274.9% compared with 31.37 million yuan in 2021. The spot market for electricity has brought about a significant increase in FM ancillary service compensation.

At present, there are not many energy storage projects applied in the field of AGC FM in Shandong Province, and only two combined fire storage FM projects are put into operation:
Huadian International Laicheng Power Plant fire storage joint FM project
Datang Linqing thermoelectric fire storage joint frequency modulation project
The 2022 earnings for these two projects are very impressive.
From January to August 2022, Huadian International Laicheng Power Plant received an average monthly compensation of 9.05 million yuan for AGC FM auxiliary service, and the average monthly compensation for Unit 3 and Unit 4 was 2.96 million yuan and 3.02 million yuan respectively (energy storage is operated jointly with these two units).
Datang Linqing Thermal Power Plant received an average monthly compensation of 4.09 million yuan for AGC FM auxiliary service from April to August 2022. The monthly compensation for Unit 1 and Unit 2 was 1.89 million yuan and 2.2 million yuan respectively.
Given that the installed energy storage capacity of these two plants is not large, the benefits are considerable at the current FM compensation level.

At present, the market rules in Shandong Province are not conducive to AGC FM auxiliary service projects for independent energy storage power plants. According to regulations, when independent energy storage devices independently participate in the FM auxiliary consumer market, the FM growth rate is 0.1, and the independent energy storage devices providing FM auxiliary services do not participate in the electricity energy market clearance, and do not participate in the price arbitrage of power engineering spot market.
It is obvious that independent energy storage power plants' enthusiasm to participate in FM auxiliary service projects will be affected in the case that the profits obtained after enjoying FM auxiliary service projects are reduced by 10% and the opportunity to participate in spot market is lost.
Energy storage is applied in Shandong AGC FM auxiliary consumer market. In a short time, it will be dominated by the form of fire storage collaborative FM. However, as a flexible and variable output power switching power supply, energy storage is very suitable for FM industry. It calls on the current policy and system makers to quickly adjust network resources for energy storage and formulate more scientific evaluation methods. Under the premise of ensuring that all kinds of switching power supply participate in the sales market fairly and reasonably, the greater use value of energy storage system can be given full play to achieve the profit of energy storage and other aspects.
