Mahanadi Coalfields, a Coal India subsidiary has floated bids for the installation and commissioning of 2.5 MW of grid-connected rooftop solar systems with net metering on residential and non-residential buildings in Odisha. The estimated cost of the project is Rs 122.29 million. According to the tender guidelines, bidders must submit Rs 1.53 million as an earnest money deposit. The successful bidder will also be required to provide a performance security of 3 per cent of the contract amount within 21 days of the letter of award. The successful bidder will be responsible for the project’s operation and maintenance for next five years.
The average annual turnover of bidders over the last three years should be at least 30 per cent of the estimated cost of the project. Only ‘Class-I and Class-II local suppliers’ are eligible to bid on the tender. Purchases will be prioritised for ‘Class-I local suppliers.’
The tender defined that the solar modules for the project must be under the Ministry of New and Renewable Energy’s Approved List of Models and Manufacturers. The monocrystalline passivated emitters and rear contact modules with a minimum capacity of 540 Wp should be used in the solar array. The efficiency of solar modules should be at least 19 per cent.
Recently in October 2022, Coal India Limited signed a Memorandum of Understanding with Rajasthan Vidyut Utpadan Nigam Limited for the development of a 1,190 MW solar power project as part of its diversification programme for clean coal energy. The move was made with an emphasis to produce clean coal and steps are being taken in this direction.
