NHPC Limited, a Government of India Navratna enterprise, has invited bids for the selection of Rooftop Developers (RTDs) to set up grid-connected solar rooftop plants across Haryana. The tender has been issued under a Notice Inviting Tender (NIT) and will be executed under the RESCO (Renewable Energy Service Company) model. The selection process will follow a tariff-based competitive bidding route along with an e-reverse auction mechanism. The project will be implemented across multiple government buildings in the state, with coordination support from the Haryana Renewable Energy Development Agency.
The bidding process will be conducted through a single-stage, two-part system. The first part will include qualification requirements along with the technical bid, while the second part will cover the financial bid. Eligible bidders must be Indian legal entities such as companies, sole proprietorships, or partnership firms. The tender also allows participation through Joint Ventures or Consortia, with a maximum of three members. In such cases, the lead member must hold at least a 50 percent stake in the consortium.
NHPC has outlined clear financial and qualification requirements for bidders based on the capacity they plan to bid for. Applicants must have a minimum net worth of ₹9,000 per kW as of the last day of the previous financial year. In addition, bidders must demonstrate financial strength through at least one of the following criteria: a minimum annual turnover of ₹4,500 per kW, a Profit Before Depreciation, Interest, and Taxes (PBDIT) of at least ₹900 per kW, or a line of credit of at least ₹1,125 per kW. These requirements aim to ensure that only financially capable developers participate in the project.
The selected developers will be required to complete the commissioning of the rooftop solar plants within nine months from the date of signing the Power Purchase Agreement (PPA). This timeline is intended to ensure the timely execution and deployment of solar capacity across the identified government sites.
The tender also specifies the cost of bid documents, which varies depending on the district. For example, the fee is ₹1,000 for Sonipat, ₹1,500 for districts such as Gurugram, Hissar, and Panipat, and ₹5,000 for locations including Ambala, Faridabad, and Rohtak. In addition, bidders must submit an Earnest Money Deposit (EMD) for each location separately. The EMD amounts vary by district, such as ₹3.8 lakh for Rohtak, ₹2.74 lakh for Rewari, ₹2.37 lakh for Faridabad, and ₹2.36 lakh for Ambala. Other districts like Karnal, Panchkula, Fatehabad, Jind, Mahendragarh, Sonipat, and Yamunanagar have EMD requirements ranging from ₹1 lakh to ₹2.23 lakh.
The bidding timeline has also been clearly defined. The tender was published on March 24, 2026. Online bid submission will begin on March 25, 2026, and will close on April 22, 2026. The deadline for offline submissions is April 23, 2026, while the technical bids will be opened on April 24, 2026.
