Energy Efficiency Services Limited (EESL), a Super Energy Service Company (ESCO) operating under the Ministry of Power, has invited Expressions of Interest (EOI) for the empanelment of agencies to conduct feasibility studies and prepare Detailed Project Reports (DPRs) for solar power projects across India. The empanelment will support the development of ground-mounted, rooftop, and floating solar projects under multiple business models, including CAPEX, RESCO, and OPEX.
Established in 2009 as a joint venture of NTPC Limited, Power Finance Corporation, REC Limited, and Power Grid Corporation of India Limited, Energy Efficiency Services Limited has emerged as one of the leading organizations in the field of energy efficiency and clean energy implementation. Through this latest initiative, the company aims to strengthen its technical consultancy capabilities and support the execution of solar projects across different regions of the country.
According to the EOI document, the selected agencies will be responsible for carrying out detailed site assessments and preparing DPRs for solar installations. The scope of work includes conducting topographical surveys, solar irradiation analysis, soil testing, and grid connectivity studies. Agencies will also have to evaluate project feasibility and prepare technical and financial reports covering energy yield analysis, project cost estimation, internal rate of return (IRR), and payback period calculations.
The empaneled consultants will further assist in selecting suitable technologies and preparing technical specifications for major equipment required in the projects. In addition, they will prepare Bills of Quantities (BOQ) and support EESL in framing commercial documents related to Engineering, Procurement, and Construction (EPC) as well as Operations and Maintenance (O&M) contracts. Software tools such as PVSyst are expected to be used for simulation and energy generation assessment.
To qualify for empanelment, applicants must have been operational for at least three years. Eligible entities include companies registered under the Companies Act, partnership firms, Limited Liability Partnerships (LLPs), registered societies, and sole proprietorship firms. However, joint ventures and consortiums are not allowed to participate in this empanelment process. Applicants must also follow the government’s Make in India guidelines, with preference likely to be given to Class-I and Class-II local suppliers.
The registration process involves online submission through the EESL portal, followed by the submission of physical documents. Required documents include GST and PAN certificates, a self-declaration related to blacklisting, and a compliance matrix. The empanelment will remain valid for two years, with a possible extension of six months based on EESL’s discretion.
As per the schedule, the EOI was issued on May 14, 2026, while the last date for submission is June 4, 2026, at 12:00 Hrs. The technical bids will also be opened on the same day at EESL’s Noida office. Interested agencies are required to submit a refundable security deposit of ₹50,000 through Demand Draft, NEFT, or RTGS as part of the application process.
