According to a government document, Rajasthan will require around 4,400 megawatts of new coal-based power capacity by 2036. This figure is more than double earlier estimates and reflects revised assessments by the Central Electricity Authority, a technical body under India’s federal power ministry. The updated projection underscores concerns about ensuring reliable, round-the-clock electricity supply as consumption continues to rise.

Rajasthan currently leads India in renewable energy output, with nearly 70 percent of its electricity coming from solar and wind sources. Vast desert land and high solar irradiance have helped the state emerge as a clean energy hub, attracting large investments in renewable infrastructure over the past decade.

However, officials and advisers argue that renewables alone cannot yet guarantee uninterrupted power. Solar and wind generation are inherently intermittent, depending on weather and time of day. Large-scale battery storage systems, which could smooth out these fluctuations, remain expensive and are not yet deployed at the scale required to support a fully renewable grid.

The revised coal capacity estimate comes as Rajasthan prepares to retire about 1,350 megawatts of ageing coal-fired power plants. These older units are less efficient and more polluting, and their planned closure aligns with India’s broader push to modernize its power sector. Even so, replacing them entirely with renewables is seen as risky given current technological and storage limitations.

India as a whole continues to rely heavily on thermal power, which accounts for roughly one-third of national electricity generation. While the country has set an ambitious target of achieving net-zero emissions by 2070 and expanding renewable capacity to 500 gigawatts, policymakers acknowledge that coal will remain part of the energy mix for decades.

Government data shows that India’s power demand is expected to surge as the economy grows, urbanization accelerates, and industrial activity expands. Meeting this demand may require up to a 40 percent increase in coal-fired capacity nationwide by 2035, even as renewable installations continue to scale up.

In Rajasthan, the upward revision of coal requirements has prompted regulatory reconsideration. The state’s power regulator has decided to review an earlier decision that denied approval for a proposed 3,200-megawatt coal-fired power plant. The review was initiated after the state power utility argued that additional baseload capacity is essential for grid stability.

The utility maintained that while renewable energy capacity is expanding rapidly, it cannot yet replace coal’s role in providing consistent power during peak demand periods or when renewable output falls. Officials pointed out that until storage technology becomes more affordable and widespread, coal plants remain a reliable fallback.

Rajasthan’s situation reflects a broader national trend. Several Indian states are accelerating coal procurement and power plant planning, citing the need to avoid shortages and blackouts. Recent years have seen sharp spikes in electricity demand during heatwaves, straining grids and reinforcing the importance of dependable baseload generation.

Energy experts note that India’s transition strategy is increasingly pragmatic rather than ideological. Instead of abruptly phasing out coal, the focus is shifting toward improving efficiency, retiring the dirtiest plants, and pairing renewables with flexible thermal capacity. This approach aims to balance climate commitments with economic growth and social stability.

The debate also highlights a key challenge for emerging economies: managing the energy transition without compromising development goals. For Rajasthan, a state that has become synonymous with renewable energy leadership, the need for new coal capacity illustrates the gap between long-term climate targets and short-term energy realities.

As India moves forward, policymakers are expected to emphasize hybrid solutions that integrate renewables, storage, and cleaner thermal power. Until storage and grid technologies mature, coal is likely to remain a critical component of energy planning, even in states that lead the renewable revolution.

The project, valued at nearly $2 billion, involves a long-term contract for Adani Power to deliver 1,500 megawatts of electricity to Uttar Pradesh, priced at 5.38 rupees per unit under a deal announced earlier this year.

However, the regulator stated that it could not proceed with final approval, as the state utility had not submitted detailed assessments of how recent policy changes might affect overall costs.

The cost-related uncertainty arises from a national policy decision introduced in July, which eased requirements for certain coal plants to install sulfur dioxide removal systems, significantly reducing expected capital expenses.

These relaxed rules are projected to save billions of rupees for coal-based power operators, yet the extent of savings for this particular project was not clearly quantified in the documents submitted.

The regulator noted that the Uttar Pradesh Power Corporation should have provided transparent analysis of the reduced expenses, including revised fixed charges and updated operating cost estimates that reflect the policy shift.

The commission has now directed the utility to include Adani Power as an active party in the proceedings, and submit comprehensive cost calculations within two weeks to clarify financial impacts.

A new hearing has been scheduled for December 18, during which updated information will be reviewed before any further decisions are taken.

In an earlier hearing held in September, the commission had already expressed concerns, stating that once emissions-control equipment was deemed unnecessary, the utility should have promptly recalculated charges under the agreement.

It also highlighted that the utility had not assessed the impact of revised goods and services tax rates on coal, a factor that directly influences the tariff structure under the long-term supply contract.

The delay highlights broader challenges in India’s coal power procurement landscape, where shifting regulatory policies and evolving emissions standards often create uncertainty for both operators and state-level distributors.

Despite India’s ongoing push for renewable energy growth, state electricity suppliers are increasingly entering long-term agreements with coal generators to address rising evening power demand.

Experts say this trend underscores the tension between short-term energy reliability and long-term sustainability commitments, as states struggle to balance immediate supply needs with national clean-energy targets.

The Adani project is part of a wider push to strengthen baseload power reserves across northern India, especially as industrial growth and household consumption continue to surge.

Analysts believe the regulator’s request for revised cost assessments is aimed at ensuring transparency, and preventing financial burdens from being passed on to consumers without proper justification.

The final decision on the agreement will depend heavily on the updated submissions from the utility and Adani Power, with authorities emphasizing the need for clarity before approving any multi-year financial commitments.

For now, the delay signals a more cautious and scrutinized approach toward large coal-based procurement contracts, particularly in states where power distribution finances remain stretched.
