There are lot competing technologies that are available to store the energy. However, it is important to choose a right solution for right application. Energy storage in this context is not just a back-up power source that is used only when grid is not available. Storage element is not going to be operated in floating applications as it is being used presently with the conventional storage technologies. However, Energy storage unit is subjected to a daily cycling when it is used in conjunction with renewable sources or Electric Vehicles. This brings a challenge of cyclic life for an energy storage unit. ESS shall have the capability to be used either as an Energy source for applications such as grid and also as power source for applications as in Electric Vehicle. In this context, we see Lithium ion battery clearly emerging as a favorable choice. Growing use of Lithium Battery in Electric vehicle is driving the demand worldwide and bringing its cost down. Benefits out of Electric Vehicle industry can be utilized for grid scale storage also. It is very important for the country to initiate few pilot projects, gain experience to deal with the grid scale storage systems. Though large scale storage systems are already installed and operational in countries like Germany, Japan we do not have any thing operational in India. While it is helpful to learn from what has been installed already elsewhere in the world, it is important to establish proof of concepts in India. This helps the industry to learn what challenges are there in Indian context and also frame regulations and policies around this segment. It has also been observed that distributed energy storage systems are already being considered for ancillary services, particularly as a Primary Control Reserve, in some countries like Germany. This gives an additional facility for individuals to participate in ancillary services. This needs a smart grid to be available, falling in line with the Government's vision of creating smart cities. While there are handful of applications and numerous advantages with Energy Storage solutions, it is important for the authorities and industry to clearly define the use cases, frame guidelines and standards so that the segment can grow as an organized segment. Realizing this impending need of Energy Storage, ACME has already installed Lithium Ion battery based Energy storage systems, and established working examples in various segments like Rural micro grids, Renewable integration at high altitude areas and building solutions. It is also giving that extra push towards localizing PCS, EMS and battery assembly in India under "Make in India" initiative.
