A sharp decline in prices of solar PV and wind technologies has inspired exponential deployment of these technologies in the energy market by the order of GWs is being hailed as a landmark towards a carbon neutral future.

With battery production reaching economies of scale, and Lithium-ion chemistry becoming a favorite across the industry for its benefit-cost ratio, BESS has become more viable than ever. Also, in comparison to the conventional counterparts such as, pumped-storage hydropower (PSH) or compressed air energy storage (CAES) which have a geographical constraint and need a certain character of terrain to become operational, BESS is the most efficient, relatively inexpensive and a thorough solution to meeting peak demands or provide ancillary services.

The inclusion of renewables in the energy mix has caused a change in the demand- generation profile, known as the infamous duck curve. BESS has greatly aided in subduing the variability and uncertain nature of renewable power. Although, the intermittent sources of energy offer a great alternative to the fossil-based power generating facilities, they have their hidden drawbacks which limits their capabilities to offer around the year dispatchability, but when coupled with a BESS their true potential is unleashed offering unrivaled benefits.

Performance, stability, reliability, and resilience are the key aspects of any power generation facility. Having realized the enormous and untapped potential of solar and wind energy which has already incentivized us for a carbon-free power generation, integrating it with energy storage technologies has further secured a safer and reliable power transmission and distribution.

Owing to its simplicity in design and modular form it is easy to integrate BESS with power production facilities, as it is it is designed to be easily configurable and highly scalable. There are various configurations of coupling BESS with a Solar PV generation facility. Choosing an optimum BESS solution entails assessing various aspects of the power generation, transmission, and distribution infrastructure.
