For new energy, remove old bottlenecks

With more than 300 GW of installed capacity, India ranks third globally in renewable-energy (RE) deployment. But this impressive growth has not always translated into green energy being available when demand is highest, particularly during the evening peak. As this newspaper reported on July 31, transmission constraints and the need to maintain grid security forced operators to curtail a significant amount of solar power-generated electricity during April to June. The Centre’s Green Energy Corridor Phase-III scheme tries to address this constraint by strengthening systems in states to evacuate up to 135 GW of renewable energy. The project will also add 50 GWh of battery energy storage.

Renewables, especially solar and wind power, have transformed the country’s energy basket, but their variability places new demands on transmission planning and storage. The new scheme is expected to address intermittency during peak hours and meet demand when the Sun is not shining. The emphasis on intra-state networks is particularly significant. Renewable projects are often concentrated in specific regions while demand is spread across cities, industries and rural areas within states. Strengthening the network’s last leg is crucial to ensuring that green power actually reaches consumers. The scheme has earmarked Rs 1,36,378 crore for transmission infrastructure. Its implementation will require learning from past experiences, which suggest that challenges are not restricted to drawing investment. A report of the Parliamentary Standing Committee on Energy tabled in Parliament in December last year, for instance, pointed out that issues related to right-of-way compensation — payment to landowners when high-voltage power transmission lines pass near their property — land acquisition and delays in environmental clearances are major hurdles in laying transmission lines.

The other major challenge will be to ensure that the 50 GWh storage component becomes a functioning part of the grid rather than a procurement target. Battery projects need viable business models and incentives — especially because the sector relies on overseas suppliers for critical raw materials — recycling arrangements and clear rules on who can use and pay for storage. The Centre and states will have to work together on planning and implementation. Renewable resources, transmission corridors and electricity demand do not follow administrative boundaries, and — as the parliamentary committee pointed out — fragmented decision-making often delays projects. Going forward, the government needs to give serious thought to the panel’s proposal for a portal that brings all approving authorities together for real-time monitoring and faster decision-making. The new corridor could be the backbone of the next phase of India’s green energy transition. It will do well to overcome the bottlenecks of the past.

Overall Analysis

The editorial examines a central challenge in India’s renewable-energy transition: generating large amounts of green electricity is not enough unless the electricity can be transmitted, stored and delivered when consumers need it. The title captures this argument through a concise metaphor. “New energy” represents the expansion of renewable power, while “old bottlenecks” refers to longstanding problems in infrastructure, land acquisition, approvals and coordination.

The opening uses a contrast between achievement and limitation. India’s position as the world’s third-largest country in renewable-energy deployment establishes the scale of progress, but the following sentence immediately qualifies this success: installed capacity does not necessarily mean electricity is available during periods of high demand. The contrast between capacity and actual availability becomes the foundation of the editorial’s argument.

The phrase “particularly during the evening peak” introduces the practical problem of renewable-energy variability. Solar power is abundant during daylight but cannot naturally meet evening demand. This makes the discussion more than a celebration of renewable capacity; the writer shifts attention towards the infrastructure required to make that capacity useful.

The editorial then introduces the Green Energy Corridor Phase-III scheme as a response to the transmission problem. The language here is largely factual and technical, with figures such as 135 GW, 50 GWh and ₹1,36,378 crore. These numbers give the argument specificity and demonstrate the scale of the proposed infrastructure.

The second paragraph develops the central argument through a useful cause-and-effect structure. Renewable energy has transformed the energy mix, but its “variability places new demands on transmission planning and storage.” The word “variability” is crucial because it captures the basic challenge of solar and wind power: generation depends on natural conditions, while electricity demand does not necessarily follow the same pattern.

A particularly effective phrase is “Strengthening the network’s last leg.” This is a metaphor drawn from transportation or connectivity. It suggests that generating electricity is only part of the journey; the final transmission network must successfully carry that electricity to actual users. The sentence “Renewable projects are often concentrated in specific regions while demand is spread across cities, industries and rural areas” reinforces this idea through spatial contrast.

The editorial then moves from infrastructure to implementation difficulties. Its enumeration of “right-of-way compensation,” “land acquisition” and “environmental clearances” shows that bottlenecks are not simply financial. The phrase “challenges are not restricted to drawing investment” broadens the argument from funding to governance and execution.

The third paragraph makes a similar argument about battery storage. The writer warns that the 50 GWh target must become a functioning part of the grid rather than merely a “procurement target.” This is an important rhetorical contrast between quantity and functionality. Simply purchasing batteries does not guarantee that storage will be effectively integrated into the electricity system.

The editorial also uses parallel listing when identifying what battery projects require: “viable business models and incentives,” “recycling arrangements” and “clear rules.” This creates a sense that successful energy storage depends on an entire ecosystem rather than one technological solution.

The final section emphasises coordination between the Centre and states. The sentence “Renewable resources, transmission corridors and electricity demand do not follow administrative boundaries” uses personification: physical systems are described as if they disregard political boundaries. This neatly expresses the mismatch between an interconnected electricity system and fragmented administrative decision-making.

The conclusion returns to the title’s metaphor. Calling the new corridor “the backbone” of the next phase of India’s green-energy transition presents transmission infrastructure as the structural support on which the broader system depends. The final phrase, “overcome the bottlenecks of the past,” creates a circular structure by returning to the central metaphor introduced in the title.

Important Vocabulary – 5

1. Curtail – to reduce, restrict or stop something, especially output or activity.
2. Intermittency – the quality of occurring irregularly rather than continuously.
3. Evacuate – in the power sector, to transmit generated electricity away from its place of production to the grid.
4. Procurement – the process of obtaining or purchasing goods or services.
5. Fragmented – divided into separate parts that may not work together effectively.

Conclusion & Tone

The editorial argues that India’s renewable-energy expansion now requires equal attention to transmission infrastructure, energy storage, regulatory coordination and project implementation. The central message is that generating more renewable power will have limited impact unless the system can reliably move and store that power.
