New Delhi [India], May 8: India’s renewable energy sector is transitioning into a more execution-driven phase, moving beyond headline capacity addition numbers with sharper focus on system-level optimisation, reliability and integrated power delivery, according to Hindustan Power Chairman Ratul Puri. This shift reflects a broader evolution in the sector, where the emphasis is no longer solely on adding capacity, but on ensuring that projects are delivered efficiently and perform consistently over the long term.
“India’s renewable energy sector is now maturing where it is not merely about adding capacity but ensuring that projects are delivered on ground with focus on round-the-clock delivery,” said Puri.
While solar and wind capacities have scaled significantly, on-ground execution continues to face structural challenges. Issues such as land acquisition, tenancy constraints and forest clearances are affecting project timelines and slowing progress across multiple levels. At the same time, delays in transmission infrastructure have impacted over 50 GW of renewable capacity under development, highlighting the importance of grid readiness alongside generation growth and the need for more coordinated planning.
The sector is also witnessing delays due to unsigned Power Sale Agreements (PSAs), driven by changing procurement strategies among DISCOMs and large offtakers. These challenges underline the need for stronger alignment between policy, infrastructure and execution, ensuring that projects are not held back by contractual or procedural uncertainties.
In parallel, India’s battery energy storage system (BESS) market is shifting from aggressive tendering to execution-led deployment. Despite approximately 102 GWh of tenders issued in 2025, only about 0.7 GWh has been commissioned, reflecting a clear gap between bidding and implementation,
Highlighting this, RatulPuri stated that “the gap between aggressive tendering and actual commissioning highlights a structural shift where success in this market will now be defined by execution capability, not just bidding strength.”
Tariff compression has supported adoption but has also tightened margins, increasing the importance of well capitalised and serious bidders, lifecycle-based project evaluation, disciplined execution and supply chain readiness. Developers are increasingly focusing on projects with clear offtake visibility, and policy support to ensure long-term viability and stable returns in a competitive market environment.
“In a tariff-compressed environment, long-term viability depends on accurately accounting for lifecycle costs, where even small variations can materially impact project returns,” Ratul Puri said.
Hybrid energy systems integrating solar, transitional power, and storage are adding operational complexity, requiring advanced coordination through Energy Management Systems (EMS) for real-time optimisation. At the same time, digital solutions are becoming central to improving performance, enabling predictive maintenance, better forecasting and dynamic dispatch across markets.
RatulPuri further noted that “digital solutions are becoming the nerve centre of energy operations, enabling real-time optimisation, predictive maintenance and stronger performance across assets.”
Looking ahead, storage is expected to play a critical role in supporting grid stability and renewable integration, even as the sector navigates risks related to supply chains, pricing mechanisms and long-term sustainability. The next phase of growth will depend on the sector’s ability to combine scale with execution strength and operational efficiency, Ratul Puri added.
Ratul Puri concluded by stating that “storage is emerging as a critical pillar of grid stability, supporting renewable integration while creating new opportunities through evolving ancillary service markets.”
