Renewable Energy Push and Demand Growth
India is rapidly expanding its renewable energy (RE) capacity, aiming for 359 GW by FY25-30 as part of its energy security strategy. This growth coincides with an expected 6% rise in power demand by FY27, driven by recovering industrial activity and climate factors. For instance, the potential impact of El Nino on the 2026 monsoon could boost power consumption, especially in residential and agricultural sectors which make up 40-45% of total demand. To ensure grid stability during this transition, the government is also adding 97 GW of thermal capacity by 2034-35. A key part of this plan involves a strong push for domestic solar manufacturing, supported by programs like PM Suryaghar and PM Kusum.
Government Mandates Drive Solar Production
Government mandates are directly stimulating demand for solar components. Policies like Domestic Content Requirement (DCR) are in place, and new rules from June 2028 will require domestic production of ingots and wafers, pushing for full backward integration in the solar supply chain. This expansion is capital-intensive, with estimates suggesting around $70 million is needed per GW for cell production and similar amounts for ingot/wafer facilities. While current shortages of domestic solar cells currently benefit early manufacturers with strong profits, the long-term economic viability and global competitiveness of this policy-driven growth are under examination.
Challenges in Cost and Scale
India's renewable energy goals, including 500 GW of non-fossil fuel capacity by 2030, rank it among global leaders. However, this progress relies heavily on policy, unlike the mature and cost-effective manufacturing hubs in China and Vietnam. The drive for domestic solar manufacturing, especially for components like ingots and wafers, demands significant investment and faces hurdles in reaching global scale and cost levels. Reports suggest Indian-made solar cells can be 1.5 to two times more expensive than Chinese imports, even with tariffs, potentially raising project costs by up to INR 10 million per MW. While El Nino has historically boosted power demand (sometimes by 4-9% due to cooling and irrigation needs), India continues to build thermal capacity (97 GW by 2034-35) as a stability measure alongside renewables. Despite rapid RE capacity growth, which saw non-fossil fuel power reach 50% ahead of schedule in 2025, its generation share is still around 25%, showing ongoing reliance on fossil fuels. The overall power sector is set for substantial investment, projected at $2.2 trillion over 20 years.
Risks for Domestic Manufacturers
The government's push for backward integration in solar manufacturing, especially the 2028 mandate for domestic ingots and wafers, heavily depends on continued policy support. Without technological advancements or greater scale, Indian makers could face a lasting cost disadvantage against international competitors, affecting profits as incentives change. The significant capital required ($70 million per GW for cells, plus similar for upstream parts) means manufacturers need strong financial planning to handle market shifts and price fluctuations. While El Nino drives demand, it's climate-driven, not steady industrial demand. Meeting India's 359 GW RE goal and adding thermal capacity also involves overcoming hurdles like grid development, land acquisition, and skilled labor shortages. Policy shifts, such as changes to the ALMM list for cells, have disrupted planning. Currently, domestic cell capacity (around 30 GW) is far below the need for module production (around 125 GW), creating bottlenecks.
Outlook: Competitiveness is Key
Growth in India's renewable energy sector is expected to remain strong, supported by energy security goals and government policies. However, the key challenge ahead, particularly for domestic manufacturing of upstream solar components after 2028, will be achieving economic competitiveness and scale. Long-term profitability and India's position in global supply chains will depend on the interaction of government policies, international trade trends, and the sector's progress in reducing costs. Meeting the sector's annual investment needs, estimated at $145 billion to achieve its growth and climate targets, will require solid financial performance and smart capital use.
