Solar+Battery storage: Assessing the Viability in India
At COP 21, the Paris Climate Conference 2015, India made a commitment that by the year 2030, India would increase the share of electricity generated from non-fossil fuels to about 40% of its total generation. To meet the commitment a major transformation is underway to replace thermal based generation with Renewable Energy (RE) complimented with energy storage technology. This shift would to be driven by the falling cost of solar panels and battery storage systems.
The rise of intermittent power sources such as solar and wind brings along the challenges in planning and operation of these power systems. The problem of intermittent power generation due to the variation in wind speed and the solar irradiation intensity throughout the day leads to
inconsistent power generation throughout the day. Another constraint is the inability to ‘control’
the generation to match the demand, as can be done in a dispatchable fossil fuel power plant.
Thus, limiting the dependency on renewable energy power in certain scenarios
The report analyzes the current cost dynamics of battery storage systems in India. Detailed analysis of technical and financial parameters of the Solar+storage system for three different scenarios for Commercial and Industrial (C&I) segments were analyzed to assess the economic viability of solar+battery storage systems across key states. The report also gives a glimpse of the need for energy storage in India, the government initiatives promoting energy storage, storage tender activity, challenges faced in the adoption of solar with storage, way forward, among other things.
