India’s Climate Stress and the Solar Power Paradox

In April and May 2026, all of the 50 hottest cities in the world were located in India, an ominous distinction for the country, which is witnessing deep, systemic climate stress. This trend has continued unabated into subsequent months, with high temperatures and humidity levels driving increased use of cooling appliances such as air conditioners across many states in India.

In July 2026, India’s electrical energy consumption grew 10.93 percent year-on-year to 170.70 billion units (BU). In comparison, the country’s total power consumption was 153.88 BU in July 2025. The peak power demand also jumped to 270.20 GW in July 2026. It was 220.74 GW in July 2025. The all-time record high was set in May this year with demand of 270.82 GW. 

The steep rise in temperature and heat waves may be a problem for people, but for the leading air conditioner manufacturers, it is a buoyant market. Companies like Voltas and LG Electronics have reported high sales. Each had already sold over 1 million units in the first three months of the year. Panasonic India said its residential AC sales increased by 50 percent year-on-year in the summer season of 2026, representing its highest-ever level.

These are very high figures for a developing country, where 60 percent of the population depends on food subsidies and power bills are on a constant rise. It also demonstrates the fact that the rising middle class, not just in metros, but also in tier-two towns and beyond, is responding to the threat and discomfort of a warming climate with significant uptake of household cooling options. Access to air conditioning, seen increasingly as a significant health issue globally, also contributes to the global warming and climate crisis. 

According to the International Energy Agency (IEA), global electricity demand is expected to grow by 3.6 percent in 2026 and 3.8 percent in 2027, driven by industry, cooling, electric vehicles (EVs), and data centers. In India, one of the world’s fastest-growing major electricity markets, it is projected to grow at 7 percent,  twice the global average. In comparison, it will grow at 5.5 percent in China, 1.8 percent in the U.S., and 2.1 percent in Europe. 

El Niño, a climate pattern in which surface waters in the central and eastern Pacific Ocean become significantly warmer than average, is projected to turbocharge extreme weather across the planet this year. India is already witnessing a deficient monsoon in 2026, attributable to the El Niño underway. According to the India Meteorological Department (IMD) and government vulnerability assessments, the country’s central, eastern, and northeastern regions face the highest drought risks. Reports have already indicated its possible impact on electricity generation. States like Odisha are considering a halt in hydropower generation to prioritize drinking water and irrigation. The southern states of Karnataka is prioritizing drinking water over irrigation for agriculture. 

However, even with the ongoing war in Iran – which has created enormous hurdles for energy imports for India – the country has managed to generate enough power to meet this rise in demand. While international energy prices have risen during the first half of the year, India’s wholesale electricity spot prices declined by around 10 percent.  This would not have been possible without India’s perennial and increasing reliance on coal, which provides 74 percent of the total power generation. 

There has been a steady growth in solar energy generation as well, under the government’s Solar Parks Scheme. Official data by India’s Ministry of New and Renewable Energy indicated that solar energy generation has surged nearly 138 percent over a four-year period, rising from 73.48 BU in 2021- 22 to 174.76 BU in 2025- 26. Currently, solar energy supplies more than 60 GW, around 22 percent of India’s daytime peak electricity demand, highlighting its growing role in meeting rising consumption. 

At the same time, however, the initiative has faced major challenges turning such massive solar capacity into stable power. Billions of units of electricity continue to be wasted because the grid cannot absorb massive surges during peak sunshine hours. Transmission lines lag behind solar park construction, leaving tens of gigawatts of capacity underutilized or on temporary connections. Moreover, coal generators struggle to reduce output quickly during peak solar production without incurring costly and lengthy shutdowns, leading to wasted solar energy on the grid.

India’s chronic pollution problem poses additional challenges. A recent study indicated that in India, aerosols in the air have reduced the amount of solar power generated by 9.6 percent in 2023, equivalent to around 15 terawatt-hours (TWh). The global average loss due to the same cause in 2023 was 5.8 percent.  Between 2017 and 2023, pollution-related electricity generation losses from existing installations averaged 74 TWh a year, which is roughly one third of the electricity generated every year by new solar capacity. India’s loss is one of the world’s highest.

The core challenge facing the country is no longer just building solar panels, but managing grid integration, storage shortages, and transmission bottlenecks that force widespread power curtailment. India’s current operational energy storage capacity includes roughly 6 GW to 7.5 GW of pumped storage hydro projects (PSPs) and over 1 GWh to 7.5 GWh of operational battery energy storage systems (BESS), which are grossly inadequate. In comparison, China’s operational non-conventional energy storage capacity reached roughly 153 GW in mid-2026. All this explains India’s continued reliance on coal-driven thermal power generation.

At one level, these can be considered expected transition problems. China, the world’s largest producer of solar energy, for example, went through a similar transition problem between 2011 and 2016, when it built wind and solar capacity far faster than it built the grid infrastructure to move that power around. India could have stood to benefit if it had learned from China’s experience and adjusted its plan accordingly. 

To address grid flexibility issues, India plans to move away from standalone solar farms toward integrated systems, making a commitment of nearly $50 billion as a share of solar investment from both the government and private players to establish substantial multi-hour storage infrastructure. But those will not happen in the near term.

India’s energy landscape in 2026 shows that the country is outpacing its infrastructure while also trying to rebuild it. Rising demand will keep coal as the backbone of the power grid in the coming years, which will create more global warming while also providing the short-term means to mitigate the effects. Aligning storage and transmission with growing renewable energy should be a top priority for energy planning. Meanwhile, heat waves and demand spikes will arise regardless of infrastructure readiness. The key challenge is ensuring that coal is not the default option in the future if India genuinely wants to achieve its newly committed climate goals of 47 percent emissions intensity reduction and 60 percent non-fossil power by 2035 alongside a long-term net-zero target by 2070.
