SECI (Solar Energy Corporation of India) Tenders

The Solar Energy Corporation of India (SECI) is a Central Public Sector Enterprise under the Ministry of New and Renewable Energy (MNRE), established as the primary institutional vehicle for procuring large-scale renewable energy on behalf of the Government of India. SECI tenders are the largest renewable energy procurement auctions in India, shaping tariff levels and driving capacity additions across solar, wind, and hybrid segments.

What are SECI (Solar Energy Corporation of India) Tenders in government procurement?

SECI functions as an aggregator and intermediary, it procures renewable energy from IPPs (Independent Power Producers) through competitive reverse auctions, and then sells this energy to state DISCOMs or large central government consumers under Power Sale Agreements. This back-to-back structure allows SECI to provide a creditworthy counterparty to IPPs (reducing their project finance risk) while offering DISCOMs access to large-scale renewable capacity at competitively discovered tariffs.

SECI's procurement covers several renewable energy technologies. Solar PV tenders range from 500 MW to 50,000 MW in size, SECI pioneered the large ultra-mega solar park concept, aggregating capacity from large solar parks in Rajasthan, Gujarat, Karnataka, Tamil Nadu, and Andhra Pradesh. Wind tenders, typically for 500 MW to 2,000 MW, are inter-state projects with wind farms in Rajasthan, Gujarat, Tamil Nadu, Andhra Pradesh, and Karnataka. Hybrid tenders combine solar and wind (and sometimes storage) to improve capacity utilisation and provide round-the-clock (RTC) power. Storage-backed renewable tenders, requiring guaranteed power supply at any time of day, are the newest and most complex category.

SECI's auction process uses an electronic reverse auction platform. Developers submit upfront bids with a ceiling tariff, then compete in real-time rounds where they can lower their tariff. The auction closes when the total capacity offered by the remaining bidders exactly covers the tendered quantity, or when a defined number of rounds pass without new bids.

Eligibility requirements are financial and technical: minimum net worth per MW of bidding capacity, relevant project experience (commissioned or under-construction capacity), and letters of comfort from equipment suppliers for the volume being bid.

Why it matters for bidders

SECI tenders are the reference point for all Indian renewable energy pricing. A tariff discovered in a SECI solar auction sets the benchmark that other states, PSUs, and corporate buyers reference in their own procurement. For renewable energy developers, winning a SECI tender provides a creditworthy 25-year PPA with a government-backed entity, the gold standard for securing project finance.

The scale of SECI tenders creates knock-on procurement opportunities. A 1,000 MW solar project awarded through SECI generates: Rs 3,000-5,000 crore of EPC procurement (module procurement, balance-of-system, civil works, electrical infrastructure), long-term O&M contracts worth Rs 15-25 crore annually, and transmission infrastructure procurement for grid connection. Each of these creates competitive tender opportunities for suppliers and contractors.

For solar module and component suppliers, SECI tenders define annual demand, when SECI bids 10,000 MW of solar capacity, the market knows approximately how many modules will be needed 18-24 months later (the typical project development timeline). Suppliers align manufacturing capacity and pricing strategies accordingly.

Example

SECI issues a tender for 2,000 MW of solar power from solar parks in Rajasthan. Twenty-five developers register as bidders. In the electronic reverse auction, bidding starts at a ceiling of Rs 2.90/kWh. After 8 rounds of competition, the auction clears at Rs 2.23/kWh with 8 developers winning capacity shares. SECI signs 25-year PPAs with the 8 winners. Simultaneously, SECI negotiates Power Sale Agreements with three state DISCOMs at Rs 2.45/kWh, the Rs 0.22/kWh difference covers SECI's guarantee fee and operational costs. Each winning developer now has the PPA security to approach lenders for project finance.

Key rules / thresholds

SECI's reverse auction platform is governed by MNRE's Revised Competitive Bidding Guidelines for procurement of grid-connected power from renewable energy sources. Developers must provide an e-bid processing fee (Rs 10-50 lakh depending on capacity bid) and a bid processing fee refundable if not selected. The PPA must be signed within 7 days of award. Project commissioning must occur within 18-24 months of PPA signing, delays beyond the commissioning deadline trigger LD equal to one month's estimated annual energy charge. MNRE's domestically manufactured solar modules requirement applies, projects commissioned from April 2022 onwards must use modules on the Approved List of Models and Manufacturers (ALMM) maintained by MNRE.
