Chennai Petroleum Corporation, a subsidiary of Indian Oil Corporation, has invited bids for a pre-feasibility study for the round-the-clock (RTC) supply of 100 MW of energy from wind and solar power projects.

The last day to submit the bids is January 27, 2026. Bids will be opened on the same day.

Bidders must furnish an earnest money deposit (EMD) of ₹30,000 (~$332).

Micro and small enterprises with a valid UDYAM registration certificate and central public sector enterprises are exempt from submitting the EMD.

The selected bidder must deposit a security deposit equivalent to 10% of the contract value.

The consultant must assess Chennai Petroleum Corporation’s power demand and consumption profile, validate the requirement assessment, and analyze current and future electricity usage patterns, tariff structures, reliability, peak demand, and the split of supply from DISCOM, captive sources, and renewable sources. This includes evaluating time-of-day and operational patterns, load factor impacts, and identifying constraints such as seasonal or critical-load requirements.

The consultant must then evaluate the technical feasibility and optimal sizing of a wind–solar configuration to deliver 50 MW RTC in Phase 1, including operation with and without energy storage, and extend the same approach to the additional 50 MW in Phase 2.

The study must include scenario analysis for different solar–wind mixes, i.e., from 100% solar–0% wind through progressively higher wind shares down to 20% solar–80% wind. This should cover the generation profile and compliance with RTC supply requirements, land needs, capital expenditure, operating expenditure and connectivity costs, landed cost, levelized cost of energy, internal rate of return, net present value, and viability for Phase 1 with an indicative evaluation for Phase 2.

The study must be completed within 10 weeks from the date of issue of the letter of award. The draft pre-feasibility report should be submitted by the eighth week.

Bidders must have carried out feasibility assessments, including project sizing for wind and solar projects (with or without energy storage systems), totaling at least 500 MW of cumulative installed capacity within the last 10 years.

Their audited annual financial turnover in any one of the last three financial years must be at least ₹1.8 million (~$19,959).

The bidders’ net worth for the last audited financial year must be positive.

In November last year, Indian Oil Corporation invited bids for the engineering, procurement, and construction of a 1 MW grid-connected solar power project at its LPG bottling plant in Tikri Kalan, Delhi, along with five years of comprehensive operation and maintenance services.
