Energy storage project in India

Energy Storage Project

In this post, energy storage project in India is given. According to department of energy (DOE), USA, till mid-2018, almost 177 GW energy storage systems are installed at grid level and 95% of it is pumped hydro storage plants. Grid scale energy storage installation in India mostly form of pumped hydro storage plant, at capacity of 4.8 GW. 

Large scale battery storage projects in India started in 2017 with power grid installed its first pilot projects for frequency regulation. The project has been designed for multiple grid service applications but in the initial operation period and they have been used for frequency regulation services. The large-scale energy storage projects are given in the table which are likely to be commissioned by 2019 and 2020.

Energy storage project in Andaman and Nicobar

The proposed energy storage projects in India 2018-19 are come up in the Andaman and Nicobar Islands to reduce diesel dependency. The SECI is evaluating energy storage project along with large scale solar and wind projects with a proposed 160 MW hybrid project in Andhra Pradesh.

Requirement of energy storage

As the installed capacity of renewable energy increases, the conventional generation will be reduced to provide base load. The renewable energy being intermittent adds its own challenge to the grid. Energy storage is being increasingly seen as flexible resource that can address this concern. The energy storage has large applications in the ancillary services, generation smoothening, load following, peak power saving, energy back up and energy time shifting etc.

As per Central Electricity Regulatory Commission (CERC) staff paper, transmission companies can be the owners of energy storage systems without being involved in trading of the stored energy. The national electricity plan highlights the role of energy storge in maintaining grid security with increasing penetration of renewable energy in addition to addressing the intermittency of RE to a large extent. Large scale batteries can be installed along with the solar and wind farms to provide suitable output to the grid.
