The electricity generation from Renewable Energy (RE) has huge fluctuations resulting in wastage of electricity & increased operational costs to the company. There is a need for a system that can store electricity and stabilize the electricity flow.
Vedanta is using RE majorly from solar sources. When there is an increase in the RE electricity generation from schedule, the electricity schedule from thermal power plant is let out and is wasted. Whereas when there is a drop in the RE electricity generation from schedule, Vedanta buys electricity from the Government grids to compensate for the gap. The electricity requirement is also highly dependent on the sudden changes in the demand schedules.
Hence Vedanta is looking to store the electricity when the generation is in excess and utilize the stored electricity when there is a drop in the generation and stabilize the power supply. For pilot implementation, a solution that can store 2MWH of electricity is preferred.
