This lack of infrastructure is a major obstacle to India's ambitious target of generating 500 GW from non-fossil fuels by 2030. While renewable energy capacity is growing rapidly, the country's ability to transmit and distribute this power is lagging, creating a wide gap between generation potential and actual delivery.
The Core Catalyst: Stranded Capacity
Rajasthan, a state rich in solar potential, is facing a major problem: an estimated 60 GW of clean energy projects are waiting for essential transmission connections. The Central Transmission Utility of India Ltd (CTUIL) has stated it cannot provide the necessary transmission systems for this large volume of applications. This problem arises from a gap in planning and execution. Rajasthan has received grid connectivity applications for about 130 GW, but transmission systems are planned or being built for only around 73 GW. CTUIL mentioned "challenges and difficulties" in finding matching transmission systems for these stuck projects. The Central Electricity Regulatory Commission (CERC) highlighted the issue's seriousness by allowing a developer to cancel its connectivity application and get back bank guarantees for a 400 MW solar park due to these transmission delays. This regulatory move signals wider planning issues.
Systemic Issues and National Context
India's power transmission network has historically struggled to keep up with the faster development of renewable energy projects, creating a growing gap with grid infrastructure. This problem affects more than just Rajasthan; an estimated 50 GW of renewable energy capacity across India was stranded due to transmission issues as of June 2025. While states like Gujarat and Andhra Pradesh have also invested heavily in renewables and infrastructure, regions like Rajasthan need strong, high-capacity transmission lines due to their concentrated renewable resources. The government's Green Energy Corridor initiative aims to better integrate solar and wind power through transmission expansion. However, annual transmission line additions have often missed targets, with FY2025 showing a 42% shortfall. Meeting India's 2030 goal of 500 GW of non-fossil fuel capacity requires an estimated $150-170 billion for transmission and storage. Projects worth ₹5 trillion are currently being bid on or built.
Investor Risks and Execution Challenges
The ongoing transmission shortage creates serious risks. CTUIL, formed in 2021 under Power Grid Corporation, handles inter-state transmission planning. However, its effectiveness is debated, and a potential transfer of its stake to Grid Controller of India (Grid India) aims to simplify operations. This proposed change points to difficulties in managing transmission. Also, CTUIL has canceled grid connections for 6.3 GW of projects since 2022 because of developer delays, showing wider issues that worsen transmission planning problems. Financially, stranded projects mean lost investment and discourage new capital, especially if Power Sale Agreements are also delayed. For developers, particularly smaller ones, long waits for transmission can cause severe financial strain, increased costs, and project failure. Although regulations like CERC's aim to improve grid access, the vast infrastructure gap, combined with delays in land acquisition, presents a major hurdle. Losses at distribution companies (DISCOMs) also add to the strain as they manage the integration of variable renewable power.
Future Plans and Solutions
Officials recognize the transmission challenge. The Central Electricity Authority (CEA) has developed a plan to integrate over 900 GW of non-fossil fuel capacity by 2035-36, which includes significantly expanding transmission lines and substation capacity at an estimated cost of ₹7.9 trillion. Projects worth ₹5 trillion are currently in the bidding or execution phase. Using High-Voltage Direct Current (HVDC) technology is also viewed as crucial for transmitting renewable power over long distances. The government is also working to enhance grid flexibility and storage to better handle variable renewable energy, understanding that a strong grid is essential for India's clean energy goals.
