Abstract

India has emerged as a global leader in renewable energy installation, achieving over 54.18% of its total installed power capacity from non-fossil sources in June 2026—five years ahead of its COP-26 commitment. With 288.59 GW of renewable capacity, India ranks 3rd globally in solar and overall renewable capacity (as per IRENA). Looking ahead, India targets 500 GW of non-fossil capacity by 2030, reinforcing its role as a key contributor to global decarbonization efforts and sustainable development goals.

However, the integration of such high levels of variable renewable energy (VRE) presents unique technical/operational challenges. The low inherent inertia of inverter-based resources (IBRs) compromises grid frequency response and voltage stability during disturbances, while the spatial mismatch between RE-rich zones and demand centers requires high-capacity, long-distance transmission networks. During FY 2025-26, India added a record 55.29 GW of non-fossil capacity, including approximately 44.6 GW of solar and 6 GW of wind, representing one of the highest annual renewable additions globally

To address these stability concerns, system planner/utility has spearheaded the deployment of Static Synchronous Compensators (STATCOMs) in renewable energy zones. This paper presents a (i) Data analysis of renewal energy integration (ii) comprehensive analysis of practical field cases demonstrating the impact of STATCOMs on enhancing dynamic grid performance (iii) Upcoming Synchronous condensers in renewable zones.
