Oil India Invites EOI To Empanel EPC Vendors For 100 MW And Above Solar Projects

Oil India Limited (OIL), a Maharatna Central Public Sector Enterprise, has issued an Expression of Interest (EOI) to empanel Engineering, Procurement, and Construction (EPC) vendors for large-scale solar power projects across India. This initiative supports OIL’s long-term target of achieving Net Zero Scope 1 and Scope 2 emissions by 2040 and reflects the company’s growing focus on clean and sustainable energy.

To implement its green transition plans, OIL has formed a wholly owned subsidiary named OIL Green Energy Limited (OGEL). The subsidiary is responsible for developing projects related to renewable energy, green hydrogen, and biogas. Through this EOI, OGEL aims to create a pool of experienced EPC vendors who can support the development of utility-scale solar power projects in different parts of the country.

The EOI is meant for the empanelment of eligible EPC vendors for a period of two years. The empaneled vendors will be considered for future projects involving grid-connected solar photovoltaic power plants with capacities of 100 MW (AC) and above. These projects may be ground-mounted, floating solar installations, or canal-top solar plants. The scope may also include solar projects integrated with Battery Energy Storage Systems, depending on project requirements.

The scope of work under future tenders will be end-to-end. It will cover design and engineering, supply of equipment, construction, testing, and commissioning of the solar power plants. In addition, selected vendors will be responsible for the operation and maintenance of the projects for 25 years, ensuring long-term performance and reliability.

OIL has set clear technical and financial eligibility criteria for applicants. On the technical side, bidders must have successfully completed at least two solar PV projects of a minimum 100 MW capacity each in the last five years. They must also have at least one year of operation and maintenance experience for a 100 MW solar project in India that is currently operational.

From a financial perspective, applicants should have an annual turnover of at least Rs. 500 crore in any one of the last three financial years and should have a positive net worth. These conditions are intended to ensure that only capable and financially stable companies are empaneled.

The EOI document states that commercial terms such as payment milestones, liquidated damages, and performance guarantees are not fixed at this stage. These details will be defined later in the project-specific Request for Quotation or bidding documents. No Earnest Money Deposit is required for submitting this EOI.

The EOI was published on February 4, 2026. The last date for submission is February 15, 2026, by 17:00 hours IST. Applications can be submitted either physically to the General Manager (C&P) at Oil India Limited, Noida, or through email. OIL has noted that incomplete applications will be rejected.
