The 4,000 MW plant is the country's first UMPP to start generation. The first unit of 800 MW was commissioned in a record 48 months of construction work starting on the project, the country's largest private power utility Tata Power said in a statement.
According to the company, work on unit 2, 3, 4 and 5 of the project is on track and progressing well.
"The 4,000 MW Mundra UMPP is the first of the UMPPs which heralds the entry of 800 MW super critical boiler technology in India which is environment friendly and efficient," it said.
The first unit was synchronised with the national grid on January 8 and achieved full load on February 25.
"We are very happy to announce the commissioning of unit 1, India's first 800 MW sized super-critical unit.
"As the first step in generating the proposed 4,000 MW power, which will benefit five states, we are proud to say that the work is on schedule," Tata Power Managing Director Anil Sardana said.
The first unit was ready for synchronisation since June 29 but was waiting for transmission evacuation system from Power Grid Corporation of India. The same got commissioned on September 29, the company noted.
The Mundra UMPP is being implemented by Tata Power's wholly-owned subsidiary Coastal Gujarat Power Ltd.
Located in the Kutch district of Gujarat, the project consists of 5 units, each of 800 MW which will generate saleable power of 3,800 MW to be supplied to five states -- Gujarat, Maharashtra, Rajasthan, Haryana and Punjab.
