NTPC Renewable Energy, a wholly-owned subsidiary of NTPC, has invited bids to enlist technical consultants for green ammonia feasibility studies.

The scope of work includes feasibility studies to assess requirements for green ammonia projects, including capital expenditure (CAPEX), operational expenditure (OPEX), and gestation period. The consultant is also expected to determine the optimum levelized cost of green ammonia.

The last date to submit the bids is April 7, 2023. Bids will be opened on April 10.

Bidders should have previously completed a feasibility study, front-end engineering design, or engineering procurement and construction management work for green ammonia production for a minimum of 10 tons per day during the last three years in a single work and at a single location.

Alternatively, they should have completed a feasibility study, front-end engineering design, or engineering procurement and construction management work for green hydrogen production for a minimum of 2 tons per day during the last five years in a single work and at a single location.

Also, they should have completed a feasibility study for grey ammonia production for a minimum of 1,000 tons per day in the last 12 years in a single work and at a single location.

The average annual turnover of bidders should not be less than ₹4 million (~$48,691) for any three of the last five financial years as of the bid submission date.

If the bidder fails to satisfy the annual turnover criteria stipulated above on its own, its holding company would be required to meet the stipulated turnover requirements. The net worth of such a holding company as on the last day of the preceding financial year should be at least equal to or more than the paid-up share capital of the holding company.

Last year, NTPC Renewable Energy issued a notice for upcoming invitations for bids to select electrolyzer technology providers to participate in green hydrogen tenders for two years. The scope of work included design, engineering, manufacturing, supply, packing, insurance, transportation, storage, installation, testing, commissioning, trial operation, and performance test of electrolyzers-based hydrogen generation plants.

Earlier, NTPC had issued an expression of interest (EoI) for Indian and global companies to set up a pilot project on green hydrogen blending with natural gas in the city gas distribution network in India.
