India’s Rapid Renewable Push Outpaces Demand, Driving Up Power Costs: CEA

India’s aggressive expansion of renewable energy capacity is creating operational and financial strains across its power grid, according to Central Electricity Authority (CEA) Chairperson Ghanshyam Prasad. Speaking at a TERI forum in New Delhi, Prasad said that while renewable output rose sharply in the first half of 2025-helping India reach 50% non-fossil capacity-the pace of demand growth has not kept up.

He noted that India’s current approach of building transmission infrastructure based on potential renewable output, rather than actual demand, has led to soaring transmission charges, worrying state utilities. The mismatch between grid readiness and renewable commissioning is also leaving some projects without power purchase agreements.

To address these challenges, the CEA plans to update transmission strategies every six months and collaborate with the India Meteorological Department to improve localized forecasting for solar and wind output. Prasad emphasized the need for integrated grid planning and resource adequacy at both national and state levels, warning that without balanced growth, developers may face “built but unsold” renewable capacity.

He added that maintaining coal, hydro, gas, and nuclear investments remains essential for grid stability and reliability.

The CEA's diagnosis captures a specific structural tension: transmission infrastructure built to potential renewable output rather than realised demand creates cost recovery challenges when demand growth lags. State utilities pay for grid capacity they cannot fully utilise, driving up transmission charges that ultimately reach consumers or erode utility financial health.

The proposed remedy - six-monthly transmission strategy updates and IMD collaboration on localised solar/wind forecasting - addresses the coordination gap between renewable-generation planning, demand-growth trajectory and grid infrastructure sequencing. Better forecasting supports more accurate infrastructure investment and reduces stranded capacity risk.
