Introduction
• The introduction of a composite bid structure for coal and solar power procurement by certain Indian states has raised concerns in the renewable energy (RE) sector.
• The structure, requiring simultaneous bidding for coal and solar power, is viewed as a potential threat to the competitive bidding system that has driven the renewable sector’s growth in recent years.
• Industry stakeholders are concerned about the exclusion of smaller players, which may dampen innovation and competition in power procurement, potentially increasing costs in the long term.
Background
• India’s renewable energy sector has flourished significantly since the introduction of competitive bidding for electricity power procurement two decades ago.
• Competitive bidding, particularly in the solar and wind sectors, has fostered competition, leading to remarkable reductions in tariffs. This has resulted in around 27 GW of solar capacity addition, primarily driven by private sector participation.
• In addition, since 2018, over 9 GW of renewable energy and 15 GWh of battery energy storage have been contracted through storage-linked tenders.
• These tenders have proven crucial in addressing the intermittent nature of renewable energy sources like solar and wind.
Difference Between Competitive Bidding and Composite Bidding in the Power Sector
• Competitive Bidding: Competitive bidding is a process where power generators or developers submit bids to provide power at the lowest possible price. The bids are evaluated primarily on the cost per unit of electricity (tariff), and contracts are awarded to the lowest bidder. This approach is commonly used in renewable energy projects like solar and wind to ensure transparency, efficiency, and cost-effectiveness.

• This approach is commonly used in renewable energy projects like solar and wind to ensure transparency, efficiency, and cost-effectiveness.
• Composite Bidding: Composite bidding is a relatively new procurement model in the power sector where a single bid combines multiple energy sources, such as coal and solar, into one tender. In this approach, power procurement is done from different types of energy sources (such as thermal and renewable) within the same contract, often requiring the developer to meet both energy demands. This method can involve different technologies or fuels but is procured under a unified contract.

Economic Impact
• The adoption of competitive bidding has played a pivotal role in reducing power tariffs for renewable energy, thereby enhancing the affordability of clean energy.
• However, the recent composite tenders, which combine coal and solar power procurement, require significant capital investments from a single or limited number of parties, potentially excluding smaller players.
• This exclusion of smaller companies may lead to a decline in competition and the associated cost reductions seen in the past.
• Additionally, concentrating procurement in the hands of a few large players could result in higher costs due to reduced market competition and diminished innovation.
• The potential risk lies in shifting from a broad, inclusive procurement system to a concentrated one, which could undermine the progress made in driving down prices in the RE sector.
Technological Aspects
• The RE sector has experienced rapid technological advancements, especially in solar power. These advancements have contributed to the efficient pricing seen through competitive bidding.
• Furthermore, the introduction of storage-linked tenders has been a crucial step to address the challenge of intermittent power generation from renewables like wind and solar.
• Technological improvements have also been seen in battery energy storage systems (BESS), with falling prices and higher efficiency rates.
• These innovations make storage an essential component for ensuring round-the-clock energy supply from renewable sources.
• The modular nature of solar and battery energy storage technologies has been instrumental in allowing scalability and customization based on regional energy needs.
Challenges and Opportunities
Challenges:
• Mismatch in Delivery Timelines: The timelines for coal and solar power projects often differ. Coal projects typically take longer to come online than solar projects, leading to potential project delivery mismatches in composite tenders.

Government Schemes
• Government schemes, such as the National Solar Mission, have played a pivotal role in promoting the adoption of competitive bidding and encouraging private sector participation.
• Subsidies and incentives for RE projects, as well as clear procurement guidelines, have facilitated market growth and innovation.
• However, maintaining policy stability and ensuring a level playing field is essential for continued progress in the sector.
International Best Practices
• Globally, many countries have successfully implemented competitive bidding mechanisms for renewable energy procurement.
• For example, nations like Germany and the United Kingdom have leveraged auctions to drive down renewable energy prices, while also ensuring a diverse and competitive market.
• These international best practices suggest that maintaining an open, competitive bidding framework can help foster innovation and cost-efficiency in the long run.
Way Forward
To ensure that India’s renewable energy sector continues to flourish, several key steps can be taken:
• Annual Procurement Calendar: Implementing an annual procurement calendar for capacity acquisition will provide greater clarity and certainty to investors, allowing for better planning and financing of projects.
