NEW DELHI — In a major infrastructure win for India’s renewable sector, Power Grid Corporation of India Limited (POWERGRID) has secured a high-voltage inter-state transmission project designed to anchor the massive Green Hydrogen and Green Ammonia production facilities emerging in coastal Andhra Pradesh.
The state-run central public sector enterprise (CPSE) formally received the Letter of Intent (LoI) on June 12, 2026, after outbidding competitors under the Ministry of Power’s Tariff-Based Competitive Bidding (TBCB) framework.
Project Scope & Technological Framework
The specialized green energy evacuation project, officially titled “Transmission system for proposed Green Hydrogen / Green Ammonia projects in Kakinada area (Phase-I)”, will be executed by POWERGRID on a Build, Own, Operate, and Transfer (BOOT) basis.
The engineering blueprint features ultra-high-voltage transmission assets designed to ensure uninterrupted power delivery to the energy hub:
-
765/400 kV GIS Installation: POWERGRID will build a next-generation Gas Insulated Substation (GIS) in Andhra Pradesh. This compact, enclosed substation architecture offers superior reliability and minimizes the environmental and land footprint compared to conventional outdoor facilities.
-
STATCOM Grid Stabilization: To combat the inherent volatility of feeding intermittent solar and wind energy into heavy industrial plants, the substation will integrate advanced STATCOM (Static Synchronous Compensator) devices for real-time voltage and power quality control.
-
Bulk Power Lines: The contract includes erecting extensive 765 kV transmission lines to bridge the gap between regional renewable generation pools and the industrial manufacturing zone.
Economic Impact on the Kakinada Hydrogen Hub
The development of this ultra-high-voltage corridor is a critical prerequisite for the industrialization of Kakinada, which is being positioned as a primary maritime hub for zero-emission fuels.
Because the synthesis of Green Hydrogen and Green Ammonia demands immense, uninterrupted baseload-style power inputs to drive industrial electrolyzers, a robust grid interface is vital. By deploying this heavy-duty transmission network, POWERGRID is establishing the foundational infrastructure necessary to attract multi-billion dollar manufacturing investments, accelerating India’s transition toward global clean energy export leadership.
