The solar plant is Fortum's third and so far biggest commissioned solar energy project, the company said in a statement here.
Fortum won a reverse auction for the project in January 2016 and the building of the solar plant was conducted on schedule.
"The power plant will operate based on a power purchase agreement (PPA) with a fixed tariff for 25 years. The PPA has been made with NTPC, India's largest power utility," it said.
Fortum currently has an 85-MW solar capacity in India, with three solar power plants in Rajasthan and Madhya Pradesh.
"Fortum is targeting a gigawatt-scale solar and wind portfolio as part of securing its longer-term competitiveness. Fortum seeks to allocate its planned growth capital in the range of EUR 200-400 million in solar projects in India," it added.
