Levelised Cost of BtM Storage in India 2021 – A Status Report

This status report aims to present a snapshot of the current cost of energy storage in India for behind-the-meter (BtM) applications.
Unreliable grid supply drives consumers towards deploying power back-up solutions such as uninterrupted power systems and diesel generators. Solar plus energy storage becomes an increasingly attractive alternative as it can provide a degree of energy security and independence to the consumer. It is cheaper, quieter, takes up less space, avoids emissions and has a shorter
Distributed solar PV and distributed energy resources (DERs) are a key part of the sustainable energy future. Compared to conventional power, the costs and benefits of DERs are more distributed in nature. We have developed the Levelised Cost Calculator for Distributed Energy Resources as a part of our efforts to quantify these costs and benefits.
Electricity tariffs for domestic consumers and several other consumer categories such as agriculture, huts, etc., are subsidized by the Government of Tamil Nadu. In addition to the electricity subsidy provided by the Government, TANGEDCO cross-subsidises the lower consumer tariffs from revenue collected from higher tariff paying customers. However, TANGEDCO is not able to recover its
The global imperative for transitioning to a sustainable energy future accompanied by increasing cost competitiveness of renewables and new technology innovations is leading us to a transformation of the electricity sector. Distributed Renewable Energy Generation (DREG) and energy storage are among the key drivers of this change. This status report attempts to trace the progress
As of the end of 2020, Tamil Nadu has an installed solar PV capacity of over 4 GW.
