Renewable energy transitions face grid transmission bottlenecks in India and Australia

Energy infrastructure challenges are emerging in India and Australia as both nations attempt to integrate increasing renewable energy capacity into their existing power grids.

In India, the expansion of the power grid is facing delays that threaten the goal of reaching 500 GW of renewable energy. A mismatch exists between the rapid development of renewable projects, which take 18–24 months, and transmission infrastructure, which can take 3–4 years. Experts suggest that generation and transmission must be planned as a single system to prevent bottlenecks. Additionally, aggressive tariff bidding has reduced financial buffers for developers, making it difficult to manage regulatory and land-use hurdles.

In Australia, Federal Climate Change and Energy Minister Chris Bowen emphasized that new transmission projects are essential not only for renewable integration but also to meet rising electricity demand following decades of underinvestment. While some regional opposition parties have pledged to scrap major projects like VNI-West, the federal government maintains that strengthening the grid is vital for the National Electricity Market. Progress is noted on projects such as the Hume Link and Project Energy Connect.
