India’s renewable energy sector has evolved from plain-vanilla solar to wind-solar hybrid and now firm and dispatchable renewable energy (FDRE) projects, reflecting growing emphasis on grid stability and round-the-clock power supply. What strategic shifts must renewable energy developers make to remain competitive in this increasingly complex and rapidly evolving market?
India’s renewable market is moving from simple capacity creation to integrated energy delivery. For developers, that means competitiveness will depend less on bidding for megawatts alone and more on the ability to design, finance, operate and optimise complex clean power systems.
The key shifts are clear:
For ENGIE, this evolution is aligned with our India strategy. We are moving from capacity addition to complexity led renewable expansion, with focus on hybrid renewables, battery storage and corporate energy solutions. Our SECI solar-plus-storage hybrid project, combining 200 MW PV with 100 MW/600 MWh battery storage, and the 280 MW/560 MWh GUVNL BESS project reflect this direction.
The next phase of competitiveness will belong to developers who can deliver clean power that is not only renewable, but reliable, flexible and commercially usable at scale
How are geopolitical tensions and evolving trade policies impacting project economics for RE developers in India?
India’s renewable energy sector is entering a phase of greater scale, maturity and strategic importance. As global trade dynamics evolve, developers are increasingly focused on building projects that are resilient, competitive and well positioned for long term performance.
This is strengthening the sector in three important ways:
India’s policy direction is supporting this shift. Measures that encourage domestic manufacturing and trusted supply chains are helping strengthen energy security, build local capability and create a more resilient foundation for renewable energy growth.
At ENGIE, we see this as an opportunity to combine global expertise with strong local execution. Our focus is on developing high quality renewable energy assets through disciplined procurement, robust risk management and partnerships aligned with India’s long term energy transition goals.
As the sector continues to scale, the developers best positioned for growth will be those who can deliver competitive, reliable and resilient clean energy projects while contributing to India’s energy security and economic ambitions.
With the expansion of the Approved List of Models and Manufacturers (ALMM) framework to solar cells, what will be the impact on ongoing and upcoming renewable energy projects? Do you see tariffs to go up in upcoming actions?
The expansion of ALMM to include solar cells is a constructive step for India’s renewable sector. It will help deepen the domestic solar manufacturing ecosystem, strengthen quality assurance, and reduce long term dependence on imported components. For developers, the priority will be to plan procurement early, work closely with approved suppliers, and build realistic assumptions into project timelines. As domestic cell capacity scales, this can create a stronger and more resilient supply base for future renewable projects.
On tariffs, the market may factor in transition costs in the near term, but the long-term direction is positive. A deeper domestic supply chain can improve certainty, reduce exposure to global trade volatility, and support more sustainable project economics over time.
For ENGIE, this aligns with India’s broader clean energy and self-reliance agenda. A stronger local manufacturing base, combined with storage, hybrid projects and disciplined execution, will help accelerate renewable deployment while building greater resilience into the sector.
Are the tariffs discovered in recent solar-plus-storage and standalone BESS auctions commercially viable? Do you see execution risks similar to those seen with standalone solar projects?
Recent auction outcomes are a positive signal for India’s energy storage market. They show that developers, procurers and financiers are gaining confidence in solar plus storage and standalone BESS as commercially relevant solutions.
The viability of these tariffs depends on disciplined project design. Storage projects need careful planning around battery sizing, technology selection, warranties, safety systems, dispatch requirements, financing and long-term operations. As the market matures, these capabilities are becoming stronger across the ecosystem.
Execution will naturally be more specialised than standalone solar because storage introduces a new performance layer. But that is also what makes these projects valuable. They are designed to deliver flexibility, peak support and more reliable clean power, not only generation.
For ENGIE, this is a strong opportunity. Our 280 MW / 560 MWh GUVNL BESS and 200 MW PV plus 100 MW / 600 MWh SECI solar plus storage hybrid project reflect our confidence in India’s storage led renewable market.
The direction is encouraging: tariffs are becoming more competitive, project structures are becoming more sophisticated and storage is moving into the mainstream of India’s clean energy transition.
Beyond lithium-ion, which storage technologies are most likely to gain traction in India over the next decade?
India will certainly evaluate alternative storage technologies as the market matures, especially for applications that require longer duration, lower material dependence or different operating profiles.
In the near term, lithium-ion BESS will continue to lead grid-scale deployment because the technology is commercially proven, bankable and supported by a developed supply chain.
But over the medium term, technologies such as sodium ion, flow batteries, gravity-based storage and other long-duration solutions can become relevant where they offer clear advantages on cost, safety, duration or local supply chain resilience.
The key point is that storage should be technology fit for purpose. A two-hour grid flexibility requirement, a six-hour firm renewable project and a longer duration balancing need may each require different solutions over time.
For ENGIE, the approach is to remain technology aware and application led. Our current India storage projects, reflect the immediate opportunity in proven BESS. As alternative technologies mature, the market will naturally assess them based on reliability, lifecycle economics and grid value.
What will determine the success of India’s transition from standalone renewables to firm, dispatchable clean energy systems?
India’s success will depend on how effectively renewable generation is integrated with storage, transmission, forecasting, market reforms and flexible commercial models.
The next phase of the energy transition is not only about adding more clean power, but about making clean power reliable, flexible, bankable and usable at scale. Hybrid and storage-backed models will be critical because they allow clean electricity to be delivered when the grid and customers need it. Stronger power markets, flexible PPAs, better scheduling, real-time optimisation and corporate demand will also shape this transition.
