India’s power demand is surging, but some solar energy is going to waste

illuminem summarises for you the essential news of the day, reviewed by our editorial team. Read the full piece on Associated Press  or enjoy below:

🗞️ Driving the news: India curtailed nearly 11 terawatt-hours of solar generation over the past 15 months, enough to supply roughly 10 million homes, according to government data and analysis by the think tank Ember
• The cuts came even as extreme heat and a weak monsoon drove record evening demand for cooling and agricultural groundwater pumping
• Grid operators ordered clean generators to reduce output because the system could not safely absorb the power available.

🔭 The context: India has surpassed 300 GW of clean capacity, more than half its installed total, yet coal still supplies most electricity
• Gujarat and Rajasthan alone hold nearly 50% of national solar capacity, congesting western transmission corridors when solar peaks in the afternoon
• Coal units cannot ramp down quickly without efficiency and cost penalties. Transmission lines take at least three years to build against roughly two for a solar farm, and India has met only about 80% of its annual transmission targets over the past five years.

🌍 Why it matters for the planet: Curtailed solar is not merely lost revenue — it is coal burned that need not have been
• Because inflexible thermal plants hold their position on the grid while renewables are switched off, emissions are being locked in by system design rather than by any shortage of clean capacity
• The dynamic is self-reinforcing: heat and erratic monsoons raise cooling and irrigation demand, which is then met disproportionately by fossil generation, deepening the warming that drives the demand
• Storage and transmission, not further panel deployment, now determine India's actual emissions trajectory

⏭️ What's next: India targets 500 GW of clean capacity by 2030 and expects nearly 70% of installed capacity to be non-fossil by 2036
• Government estimates put storage requirements at about 74 GW by 2032. A study this month from UC Berkeley's India Energy and Climate Center found renewables paired with batteries can approach conventional reliability at a cost below new coal
• Analysts recommend geographic diversification, more wind, and distributed solar to relieve congested corridors

💬 One quote: Making thermal plants flexible enough to accommodate rising renewable supply "is like asking an elephant to dance" — Vinay Pabba, CEO of Vibrant Energy.

📈 One stat: About 3 GW of operational battery storage today, against an expected national requirement of roughly 74 GW by 2032
