A Decade of Energy Challenges Ahead
Tamil Nadu’s Energy Forecast for 2034–35: Rising Demand and Looming Power Deficit: Tamil Nadu, despite being one of India’s most energy-conscious and industrially advanced states, is projected to face consistent energy shortages over the next ten years. As per recent estimates, the energy deficit could reach a staggering 45,587 million units (MU) by 2034–35. This anticipated shortfall raises serious concerns regarding generation expansion, grid resilience, and the need for smarter energy consumption practices.
Demand-Supply Patterns in 2023–24
In 2023–24, the state managed to meet a peak demand of 19,045 MW with only minimal disruptions. The total energy required during this fiscal was 1,26,163 MU, while 1,26,151 MU was successfully supplied—resulting in a marginal gap. By the end of March 2024, Tamil Nadu had secured 36,593 MW of contracted capacity, with non-fossil fuel sources contributing around 61%, affirming its steady progress toward clean energy adoption.
Breaking Energy Consumption Records
Tamil Nadu reached unprecedented power usage milestones in 2024. On May 2, it recorded a historic peak demand of 20,830 MW, while April 30 witnessed the highest daily consumption of 454.32 MU. These figures signal a fast-accelerating demand curve, especially during summer months. Projections indicate even higher peaks in 2025, emphasizing the urgency of boosting both generation and transmission capacity.
What Lies Ahead in 2034–35
By 2034–35, Tamil Nadu’s power demand is expected to nearly double, with peak load projected at 35,507 MW and annual consumption crossing 2,49,580 MU. To support this growth, the state plans to increase its total contracted capacity to 98,140 MW. A significant highlight of this transition is the rising contribution of green energy, expected to grow from 64% in 2024–25 to 77% by 2034–35, reflecting Tamil Nadu’s strong renewable energy strategy.
