2020 Solar Plus Energy Storage: Feasibility of Behind-the-Meter systems for LT consumers in Tamil Nadu

Solar Plus Energy Storage

A transition towards a decarbonized and sustainable energy future will incorporate renewable energy sources, such as solar and wind. The intermittency of these renewable sources creates a substantial mismatch between energy produced and required. Energy storage plays an important role in balancing supply and demand and helps to create a more flexible and reliable electricity grid. If we want to source 100% of our electrical energy from renewables by 2050, significant investment in energy storage is necessary. 
Lithium-ion (Li-ion) battery is a rapidly developing and the future energy storage solution, the cost of Li-ion battery has seen a steady decline over the past years, this trend is expected to continue for the foreseeable time. A 78% reduction in the cost of Li-ion battery pack over the 2015 cost is expected by 2030. Consumers, in India particularly, are highly cost-sensitive. With the increasing affordability solar plus energy storage becomes a viable investment option while at the same time providing a certain degree of energy security and independence for the consumer. 
This report focuses on the financial feasibility of investing in solar plus energy storage (lithium-ion) on the consumer side of the service connection (behind-the-meter) for selected LT consumer categories in Tamil Nadu.
