Chennai Petroleum Seeks Consultants for Pre-Feasibility Study of 100 MW Wind-Solar RTC Projects

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

The bid submission deadline is January 27, 2026, and the bids will be opened on the same day. Interested bidders are required to submit an earnest money deposit (EMD) of Rs30,000. However, micro and small enterprises holding valid UDYAM registration certificates, along with central public sector enterprises, are exempt from the EMD requirement.

The successful bidder will be required to furnish a security deposit equal to 10% of the contract value.

As part of the assignment, the consultant will evaluate CPCL’s power demand and consumption profile, including current and projected electricity usage, tariff structures, supply reliability, peak demand, and the distribution of power sourced from DISCOMs, captive generation, and renewable energy. The assessment will also cover time-of-day usage patterns, load factors, and operational constraints such as seasonal variations and critical-load requirements.

The study will involve analysing the technical feasibility and optimal sizing of a wind–solar hybrid configuration to deliver 50 MW of RTC power in Phase 1, both with and without energy storage systems. A similar assessment will be extended to an additional 50 MW under Phase 2.

Bidders are required to conduct scenario-based evaluations of different wind–solar mixes, ranging from 100% solar and 0% wind to 20% solar and 80% wind. The analysis must cover generation profiles, compliance with RTC requirements, land requirements, capital and operating costs, connectivity expenses, landed power cost, levelized cost of energy (LCOE), internal rate of return (IRR), net present value (NPV), and overall project viability for Phase 1, with indicative projections for Phase 2.

The pre-feasibility study is to be completed within 10 weeks from the date of issuance of the Letter of Award, with a draft report to be submitted by the eighth week.

To be eligible, bidders must have completed feasibility studies or project sizing exercises for wind and solar projects—with or without energy storage systems—aggregating at least 500 MW of installed capacity over the past 10 years. In addition, bidders must demonstrate a minimum audited annual turnover of Rs1.8 million in any one of the last three financial years and maintain a positive net worth in the most recent audited financial year.
