The turnkey order valued at 350 million rupees ($5.2 million) involves eight substations, ranging in size up to 132 Kv, the company said in an online statement.
"Renewable energy is one of our focus areas, and we want to make a difference in connecting solar energy to the grid through the integration of our power system capabilities," said Hartek Singh, chairman and managing director of the group.
The company will handle all aspects of the projects for New Delhi-based Azure Power, from design to commissioning.
Its total first-half orders now stand at 460 MW, including 16 substation projects, the Business Standard reported this week.
It is now working on a number of other substation orders, valued at roughly 600 million rupees.
It expects its cumulative orders to surpass 1GW by the next fiscal year, with roughly half of that capacity to be installed in southern India.
