New Delhi: India recorded its highest ever monthly renewable electricity generation in July, marking another important step in the country's transition towards cleaner energy. The strong performance from solar and wind power reduced coal's share in the national electricity mix to its lowest level in a year. Even so, coal continued to play a major role in meeting the country's rapidly growing demand for electricity, showing that India still faces a balancing act between expanding clean energy and ensuring reliable power supplies.
According to data reported by Reuters and supported by recent developments from other major news sources, renewable energy generated around 36.25 billion kilowatt hours of electricity during July. This represented an increase of nearly 30 percent compared with the same month last year. Renewables contributed about 20 percent of India's total electricity generation during the month, the highest monthly share ever recorded.
The increase was driven mainly by strong solar power production during long summer days and higher wind generation as the southwest monsoon strengthened across many parts of the country. India has also added large amounts of new renewable energy capacity over the past two years, helping boost clean electricity production to record levels.
While renewable energy achieved a significant milestone, India's overall electricity demand continued to rise sharply. Total electricity generation reached around 181.8 billion kilowatt hours in July, an increase of more than 10 percent from the previous year. Rising temperatures, increasing use of air conditioners, expanding industries, growing data centres and the wider adoption of electric vehicles have all contributed to higher electricity consumption across the country.
Because of this strong demand, coal fired power stations continued to generate more electricity even though their overall share in the power mix declined. Coal accounted for about 65.7 percent of India's electricity generation in July, down from around 69 percent in June and marking its lowest monthly share in one year. However, coal based electricity generation still increased by nearly 13 percent compared with July last year because the country's total demand for power grew even faster than renewable generation.
Another important milestone was reached on July 13 when combined solar and wind generation exceeded 100 gigawatts for the first time. During peak daytime hours, renewable energy briefly supplied nearly 43 percent of India's electricity demand. Energy experts say this achievement highlights how quickly solar and wind projects are expanding across the country and how renewable energy is becoming an increasingly important part of India's electricity system.
Despite these achievements, several challenges remain. Hydroelectric power production declined for the second consecutive month because rainfall was below expectations in some regions. Lower hydropower output meant coal fired power plants had to generate more electricity, particularly during the evening when solar power production falls after sunset.
India is also facing growing pressure to improve its electricity transmission network. Recent reports indicate that a portion of the country's installed solar capacity cannot operate at full output because existing transmission lines are unable to carry all the electricity produced. During recent months, thousands of gigawatt hours of clean electricity had to be curtailed because of congestion in the national grid. Experts say expanding transmission infrastructure and investing in battery storage systems will be essential if India is to make full use of its rapidly growing renewable energy capacity.
The government has continued to support renewable energy expansion while also maintaining coal supplies to ensure uninterrupted electricity generation. Officials have said coal inventories at power stations remain comfortable and that additional thermal generating capacity is being added to support rising electricity demand until renewable energy and energy storage systems can fully meet future requirements.
India has set ambitious clean energy goals and continues to rank among the fastest growing renewable energy markets in the world. However, experts believe coal will remain an important part of the country's energy system for several more years as electricity demand continues to rise and renewable infrastructure expands.
The record renewable generation achieved in July demonstrates the rapid progress India has made in building a cleaner energy sector. At the same time, the continued growth in coal generation shows that the country's energy transition is likely to be gradual, requiring major investments in transmission networks, battery storage and grid modernisation to ensure renewable energy can reliably meet the needs of one of the world's fastest growing economies.
