Powering India’s Green Grid: PM-DHARA Scheme and the Next Leap in Renewable Energy Transmission
Powering India’s Green Grid: How PM-DHARA Can Transform Renewable Energy Transmission
A comprehensive UPSC analysis of PM-DHARA, Green Energy Corridor Phase III, renewable-energy evacuation, Battery Energy Storage Systems and India's emerging green-grid architecture.
PM-DHARA is a ₹1.86 lakh crore green-energy infrastructure programme aimed at strengthening intra-state transmission, enabling evacuation of up to 135 GW of renewable power and deploying 50 GWh of battery storage.
For UPSC, the scheme links renewable-energy integration with energy security, infrastructure, battery technology, climate action and green growth.
What is the PM-DHARA Scheme?
PM-DHARA — PM-Developing Harmonized and Accelerated Renewable-energy Access is a major green-energy transmission and storage programme.
It aims to strengthen electricity networks within States and Union Territories while improving India's ability to integrate large quantities of renewable electricity into the grid.

Why Does India Need Green Energy Transmission?
Renewable-energy generation is often concentrated far from major centres of electricity demand.
Solar potential may be high in Rajasthan and Gujarat, while wind generation can be concentrated in coastal and southern States. Electricity demand, however, is distributed across cities, industries and agricultural regions.
A stronger green grid changes the equation:
What is Renewable Energy Evacuation?
Electricity evacuation refers to transporting generated electricity from the power-generation facility into the wider electricity grid so that it can ultimately reach consumers.
Without adequate evacuation infrastructure, renewable-energy projects may generate electricity that the grid cannot efficiently absorb or transmit.
Green Energy Corridor Phase III
A major component of PM-DHARA is the development of Intra-State Transmission Systems under Green Energy Corridor Phase III.
50 GWh Battery Energy Storage: Why It Matters
PM-DHARA provides ₹50,000 crore for 50 GWh of Battery Energy Storage Systems (BESS).
What is BESS?
A Battery Energy Storage System stores electricity in batteries and releases it when electricity is required.

More Reliable Renewable Power
The Problem of Renewable Intermittency
Solar and wind generation are inherently variable. Solar generation falls after sunset, while wind generation changes according to weather conditions.
Electricity demand, however, continues throughout the day. This creates a mismatch between when renewable electricity is generated and when consumers need electricity.
How BESS Can Help the Grid
Central Financial Support
The financial assistance is intended to reduce the burden of intra-state transmission costs and help contain electricity costs for consumers.
How Will PM-DHARA Projects Be Implemented?
Greenfield Projects
New transmission projects will use a competitive project-allocation framework.
Tariff Based Competitive Bidding — TBCBBrownfield Projects
Existing transmission-network strengthening and augmentation will follow the applicable cost-based framework.
Cost Plus Basis — CPBRole of State Transmission Utilities
State Transmission Utilities (STUs) are envisaged as the overall implementing agencies.
Transmission Service Providers selected through competitive bidding can develop projects using the Build-Own-Operate-Maintain (BOOM) model.
