Rajasthan Electronics & Instruments Limited (REIL), Jaipur, has issued a Notice Inviting Tender (NIT) for a significant solar energy project. The tender is aimed at securing a rate contract for the survey, design, supply, erection, testing, commissioning, and comprehensive operation and maintenance (O&M) of Grid-Connected Rooftop Solar Photovoltaic Power Projects across various Government buildings in India. This rate contract will span 17.55 MW of solar power capacity.
The contract will be valid for one year but may be extended if required. The total capacity will be distributed across various zones in India, and bidders have the option to quote for one or multiple zones, with the submission deadline for online tenders set for February 10, 2025. The technical bids will be opened on February 11, 2025, and a pre-bid meeting will take place on January 27, 2025. The validity of offers will be for 90 days from the last date of tender submission.
Bidders need to submit an Earnest Money Deposit (EMD) for each selected zone. The amount will be 2% of the estimated rate for the respective zone, with EMD requirements adjusted if a bidder chooses to bid for multiple zones. Techno-commercial eligibility will be evaluated based on the selected zones, and bidders must meet the required criteria. Work orders will be allocated to successful bidders after receiving orders from end customers to REIL. For work execution, bidders will first need to conduct a site survey (if required) and submit a feasibility report.
The solar power plants to be installed will have a capacity ranging from 51 kWp to 1000 kWp per government building. The work will be divided into L-1 and L-2 categories, with L-1 bidders being allocated 70% of the total capacity and L-2 bidders receiving 30%, all at the L-1 rate for a particular zone. REIL has the authority to adjust the final allocation as per the customer’s requirements.
To qualify, the bidder must be a company or firm incorporated in India and have experience in designing, supplying, and installing grid-connected solar power plants. Alternatively, Limited Liability Partnerships (LLPs) registered under the LLP Act, 2008, with similar experience, can also apply. The bidder must have completed at least one similar work in government buildings during the last seven years, either by completing three works worth 40% of the estimated cost, two works worth 50%, or one work worth 80%. In addition, at least one of these projects must include operation and maintenance (O&M) for a minimum of one year.
The scope of the work will use Mono-Perc Solar Panels with a capacity of 540Wp or more, complying with the MNRE (Ministry of New and Renewable Energy) notification of April 29, 2024, regarding approved solar photovoltaic (PV) module models. The solar inverter must be purchased from a Class-I local supplier, following the government’s “Make in India” initiative. The O&M period for the solar plants will last for 10 years from the completion date, but it may be shortened depending on the customer’s needs.
Construction-related services, including the provision of power and water, will be the responsibility of the bidder, but basic amenities like electricity will be supplied at one point on each site. Additional arrangements for power and water will also need to be made by the bidder within the quoted price. The bidder must ensure safe and easy access to the rooftops of the buildings by installing permanent MS ladders where necessary.
Solar PV modules will be sourced from a Class-I local supplier and must meet specific quality standards. The modules should comply with IEC 61215, IS 14286, IEC 61730, and other related standards, ensuring durability and efficiency. A temperature coefficient of power of -0.40%/°C or better is required, and the modules should have a minimum efficiency of 21%. The module warranty should ensure at least 90% of the rated output for the first 10 years and 80% for the next 15 years. Additionally, each solar module must be equipped with an RFID tag containing essential traceability information.
The design and installation of the mounting structures for the solar modules must meet specific guidelines, and the work should be certified by a recognized lab or chartered engineer. The material used for the module mounting structure (MMS) can include hot-dip galvanized iron, aluminum, or mild steel, with mild steel being preferred for raised structures. The final design should account for wind loading and other factors as per the standards.
Meters for energy generation and net consumption must be installed at the sites, with solar meters having a minimum warranty of 10 years. All meters should be compatible with the respective DISCOMs and comply with local regulations. If the meters fail within the warranty period, the bidder is responsible for their replacement.
In summary, REIL’s tender presents a significant opportunity for companies with experience in the solar energy sector to contribute to India’s solar revolution by installing rooftop solar PV systems on government buildings across various zones. The project emphasizes quality, local sourcing, and long-term sustainability, aligning with India’s broader renewable energy goals.
