India's Renewables Surge, Costly Demand Mismatch

A rapid buildout with rising costs attached

India's renewables surge exposes a costly demand mismatch that is starting to filter through to power bills and utility balance sheets. Chairperson Ghanshyam Prasad of the Central Electricity Authority (CEA) said on November 7, 2025 that India’s rapid renewable energy rollout, built to hit ambitious 2030 targets, is straining grid operations and contributing to higher electricity supply costs because demand growth and actual offtake have not kept pace. The country has reached roughly 50 percent of installed capacity from non fossil sources and is on track to add more than 40 gigawatts of solar and wind this year, yet parts of the system are paying for lines and capacity that remain underused.

Building for potential, not real demand

Prasad outlined a core problem: transmission corridors have been designed around potential renewable generation, not around confirmed projects or firm demand. That approach was intended to stay ahead of the investment curve; instead, it has produced pockets where expensive high voltage networks run well ahead of utilization. Transmission charges, paid largely by state distribution companies and ultimately consumers, have climbed as costs are socialised across the system. For cash constrained utilities, higher open access and system charges tied to barely loaded assets are a growing concern, particularly in states where demand has risen more slowly than planners assumed.

Projects without buyers

The demand mismatch is already visible in project economics. In several renewable corridors, capacity has been built or awarded faster than bankable power purchase agreements have been signed. Developers face the risk of having operational or near ready plants without long term offtake, while still relying on transmission infrastructure that pushes up pooled costs. The result is an uneasy paradox: India has lined up clean generation potential, yet some of that potential cannot be evacuated or monetised efficiently. That disconnect is at the heart of the costly demand mismatch troubling policymakers and investors.

CEA’s course correction plan

To narrow the gap, the CEA plans to revise transmission plans every six months instead of waiting multiple years between major updates. The objective is to align buildout more closely with actual commissioning schedules, realistic demand trajectories and state level purchasing strategies. Prasad also highlighted work with the India Meteorological Department on more granular weather forecasting for solar and wind, so grid operators can better schedule dispatch and avoid either stranding capacity or overpaying for backup reserves. A more iterative approach is intended to prevent a repeat of overbuilt corridors that weigh on tariffs.

Why costs are rising despite clean capacity

In theory, cheap renewables should ease long run power costs. In practice, India’s experience shows how sequencing matters. Transmission built too early, integration systems that lag and uneven policy signals can turn a climate success story into a financial strain. Underutilised lines still recover their regulated returns; balancing fossil fleet flexibility, storage gaps and curtailment risk adds further expense. When these layers stack up, average supply costs rise even as fuel free megawatt hours increase. For distribution companies under political pressure to hold tariffs steady, this structure is difficult to absorb.

Demand realities on the ground

Electricity demand in India is growing, but not uniformly and not always where the newest renewable hubs are located. Industrial clusters, urban centres and agricultural loads follow patterns that do not perfectly match solar and wind resource maps. Some states are more reluctant to lock in long term clean power at today’s prices; others have financial stress that limits new commitments. Without better coordination between central planning, state utilities and private developers, the system risks continuing to add capacity where the grid can technically handle it, but where demand or creditworthy buyers are insufficient.

Keeping coal and firm capacity in the frame

Prasad underlined that India cannot rely on renewables alone to guarantee reliability. Coal, hydro, gas and eventually more nuclear will remain part of the mix to provide firm capacity and ramping support. The message is pragmatic: resource adequacy must be planned holistically so that variable renewables are complemented by dispatchable sources, not left to compete against them in an unstructured way. If planners underestimate the need for firm backup, grid risks rise; if they overbuild both, consumers pay for redundancy. Striking the right balance is central to containing costs while meeting climate goals.

Investor and developer implications

For developers, India’s renewables surge, costly demand mismatch dynamic alters risk calculations. Strong headline targets and auction volumes are not enough; clarity on offtake, grid readiness and congestion is now critical to securing finance at competitive rates. Transmission strategy revisions every six months could improve transparency, but they may also expose projects that no longer fit updated corridors or demand assumptions. International investors focused on clean infrastructure will watch whether policy adjustments translate into bankable, enforceable contracts or remain high level guidance.

What India must fix next

The official diagnosis points toward an integrated approach: align generation, transmission and distribution planning; tie corridor design to credible demand and PPA pipelines; use better forecasts to dispatch renewables more efficiently; and ensure that the cost recovery framework does not penalise states and consumers for central overbuild. If India can tune this framework, its rapid renewable expansion can deliver both decarbonisation and competitively priced power. If not, the risk is political pushback against clean energy, as stakeholders associate the transition with unnecessarily high bills.

Bottom line

India's renewables surge exposes a costly demand mismatch that has pushed up transmission charges and left parts of the clean fleet underused. The CEA’s shift to more dynamic planning and better forecasting is an attempt to close that gap; success will determine whether record renewable additions translate into affordable, reliable power or remain an expensive promise.
