Switzerland-based automation company ABB has commissioned five substations to connect a 648MW solar project in Kamuthi in Tamil Nadu to the national transmission grid.

Last year, ABB received the project from an independent power producer (IPP) Adani Group and has completed it on schedule.

The Kamuthi project features five photovoltaic (PV) plants and is the world’s largest of its kind. Of the 648MW generated, 360MW is currently grid-connected and operational.The facility will account for approximately 10% of India’s current solar capacity.

ABB’s power grids division president Claudio Facchin said: "We are proud to support the country’s clean energy vision and push for solar power, which demonstrates its commitment to sustainable growth.

"The Kamuthi project features five photovoltaic (PV) plants and is the world’s largest of its kind."

"This project exemplifies our end-to-end power and automation system integration capabilities and reinforces our commitment to the renewable energy sector, a key component of ABB’s next-level strategy."

The project includes the design, supply, installation, and commissioning related to the solar plant electrification and automation systems. This involves two 230kV and three 110kV outdoor switchyards, which will be used to connect to the local transmission grid and facilitate clean power supply for nearly 150,000 households based on average national per capita consumption.

The project is a part of India’s vision to achieve 100GW of solar power by 2022. The government of Tamil Nadu is pursuing a solar policy, which aims to attain a generation capacity addition of 3,000MW.
