India's power grid just got a landmark green upgrade. Uttarakhand Chief Minister Pushkar Singh Dhami on Wednesday, 30 September 2026 welcomed the Union Cabinet's approval of the Green Energy Corridor Phase-III, a mammoth ₹1.86 lakh crore transmission infrastructure programme designed to carry renewable electricity from generation hubs to the national grid at unprecedented scale.

What Phase-III Promises: 135 GW Integration and 50 GWh Storage

The Cabinet decision, as cited by CM Dhami, targets the integration of up to 135 GW of renewable energy into the national grid — a figure that would dwarf anything attempted under the corridor's earlier phases. Equally significant is the addition of 50 GWh of battery storage capacity, which addresses the intermittency problem that has long been the Achilles heel of solar and wind power. Storage at this scale means surplus generation during peak sunshine or wind hours can be banked and dispatched when demand spikes after dark.

Dhami framed the approval as 'direct proof' — pratyaksh praman — of India's accelerating march toward energy self-reliance under Prime Minister Narendra Modi. The Chief Minister linked the decision explicitly to the national ambition of achieving 900 GW of non-fossil energy capacity by 2035, a target that sits well beyond India's earlier COP26 Panchamrit pledge of 500 GW non-fossil capacity by 2030.

Phase-I and Phase-II: The Foundation This Builds On

Green Energy Corridor is not a new idea — it has a decade-long lineage. Phase-I was approved in 2015 to build inter-state transmission lines evacuating power from renewable-rich states including Rajasthan, Gujarat, Himachal Pradesh, and Tamil Nadu. Phase-II followed between 2018 and 2020, deepening intra-state grid infrastructure. Phase-III now represents the programme's most ambitious leap, both in financial outlay and technical scope, scaling the architecture built over a decade to absorb a grid that is rapidly filling with solar parks and wind farms.

India's renewable capacity has grown sharply over this period, making transmission the critical bottleneck. A generator that cannot evacuate its power earns nothing and delivers nothing — which is precisely the problem a dedicated green corridor is designed to solve.

Viksit Bharat's Energy Spine

CM Dhami positioned the approval squarely within the Viksit Bharat ('Developed India') roadmap, the overarching policy framework the Modi government has used to anchor long-horizon targets across sectors. For energy, that roadmap demands not just more capacity but a grid resilient enough to carry it reliably. Battery storage at 50 GWh is the insurance policy: it buffers the grid against the volatility of weather-dependent generation and reduces dependence on coal-fired peaking plants that are typically fired up to cover evening demand surges.

State-level power utilities and private renewable energy developers are the two constituencies that will feel this decision most immediately. Faster evacuation infrastructure reduces the risk of renewable projects being stranded — a persistent concern that has at times slowed private investment in large solar and wind parks.

With the Cabinet's pen stroke, India has drawn the transmission backbone for a grid it is still building. Whether state utilities can execute at the pace the ambition demands will be the defining question of the next three years.
