HPCL Renewables and Green Energy, a sub-unit of Hindustan Petroleum Corporation (HPCL), issued a proposal for a 78 MW wind-solar hybrid power project for engineering, procurement, and construction (EPC). The comprehensive operation and maintenance (O&M) will be done by the contractor for the stipulated 10 years. It is anticipated that the hybrid project would offer its Mumbai refinery continuous electricity to produce at least 50% green energy at 686 MU. The refinery's contracted load is 90 MW. By 2040, HPCL Renewables & Green Energy wants to have zero net carbon emissions and switch to renewable energy for the grid electricity used at its refineries. The contractor is responsible for guaranteeing that the project will provide the refinery with a minimum of 343 million kWh of electricity annually. Either the solar or wind component's rated installed capacity must be 25% higher than the other component's rated installed capacity. The proposals must be submitted by May 24 of this year, at the latest. A $841,894 earnest money deposit is required of bidders. A performance bank guarantee equal to 5% of the EPC contract value and an O&M bank guarantee equal to 5% of the O&M value must be submitted by the chosen bidder. To serve the Mumbai refinery, the contractor will be in charge of locating the site, securing connectivity and permissions, and putting electricity into intra- and interstate transmission networks. The projects can be situated anywhere in India on property that is not in a Great Indian Bustard zone and has a minimum 27-year leasehold. The separate parts (wind and sun) might or might not be placed close to one another. For projects located outside of Maharashtra, a Central Transmission Utility connection is necessary; for those located inside the state, a State Transmission Utility connection is needed. The chosen contractor will be in charge of removing the electricity from the producing source and bringing it to the Trombay substation's injection point. The project needs to be fully operationalized within 18 months of the grant letter being received. Liquidated damages equal to 0.5% of the whole EPC contract value, up to a maximum of 10%, shall be applied in the event of a delay. The wind turbines used in the project must come from the Ministry of New and Renewable Energy's Revised List of Machine Manufacturers, and the solar modules utilised must come from the Approved List of Models and Manufacturers. A 1,500V system requires a minimum of 540 Wp from the solar panels. The ability to commission comparable projects with a minimum 100 MW solar, wind, or wind-solar hybrid power capacity, either inside or outside of India, must be possessed by the winning bidders. They have to have completed a minimum of three of these projects, each worth at least $65.27 million, or two comparable projects, each worth at least $81.55 million, or one comparable project worth at least $130.41 million. The bidders' three-year average annual turnover, ending on March 31, 2024, must have been at least $48.98 million. On behalf of its subsidiary HPCL Renewable & Green Energy, HPCL issued an invitation to bid earlier this month for the EPC package of a 100 MW solar power project in Galiveedu, Annamayya district, Andhra Pradesh.
