Summary of Renewable Energy Auctions: Analysing 2016

Core Content

This report by the International Renewable Energy Agency (IRENA) provides an in-depth analysis of renewable energy auctions held in 2016, focusing on their role in promoting renewable energy deployment, the trends observed in auction prices, and the factors influencing these outcomes. It also includes case studies from various countries and discusses the implications of using auctions for less mature technologies such as offshore wind and bioenergy.

Main Trends in Renewable Energy Auctions

• Global Expansion: Renewable energy auctions have gained traction worldwide, with the number of countries adopting them increasing from 6 in 2005 to at least 67 by mid-2016.
• Competition and Cost Reduction: Auctions have proven effective in driving down the cost of renewable energy, particularly solar PV and onshore wind.
• Policy Integration: Auctions are often used in conjunction with other policy instruments such as feed-in tariffs, quotas, and support mechanisms.
• Design Flexibility: Auctions are adaptable to different market structures, including liberalised markets, single-buyer systems, and vertically integrated monopolies.
• Investor Security: The use of legally binding contracts in auctions provides greater investor security compared to feed-in tariffs or green certificate systems, unless additional safeguards are included.

Key Views and Information

1. Price Trends

• Solar PV: Global solar prices dropped significantly from USD 250/MWh in 2010 to USD 50/MWh in 2016. In 2016, the lowest solar prices were recorded in the United Arab Emirates (USD 29.9/MWh) and Mexico (USD 27/MWh).
• Onshore Wind: Wind prices also declined, though at a slower rate. In 2016, the lowest wind price in Latin America was USD 32/MWh in Mexico, while Germany achieved prices as low as EUR 65.8/MWh (USD 70.1/MWh) in 2017.

2. Factors Influencing Auction Prices

• Access to Finance: Countries with better access to finance and stable economic conditions tend to achieve lower auction prices.
• Investor Confidence: A conducive regulatory and institutional environment fosters investor confidence, leading to more competitive bids.
• Policy Support: Strong policy frameworks, including subsidies, feed-in tariffs, and incentives, play a crucial role in attracting bidders and ensuring project viability.
• Auction Design: The structure of the auction, such as the use of capacity bands, payment security mechanisms, and contract terms, significantly affects the final price.

3. Country Case Studies

• Argentina: Launched the RenovAR programme, which included liquidity and solvency guarantees to reduce investor risk. Local content requirements were also introduced.
• Brazil: Conducted multiple auctions for solar, wind, and biomass, with the 2016 auctions showing significant price reductions. The country has experience with both technology-neutral and technology-exclusive auctions.
• Chile: Organised one of its largest energy auctions, with a focus on reducing investor risk through hourly supply blocks.
• Germany: Continued its solar auction programme, achieving record-low prices and demonstrating the effectiveness of auctions in replacing feed-in tariffs.
• India: Held 16 auctions, with solar and wind prices falling to unprecedented levels. The auctions were instrumental in achieving the country's solar target of 100 GW by 2022.
• Mexico: Conducted two major auctions in 2016, leading to the lowest solar and wind prices in Latin America.
• Peru: Achieved record-low prices for wind and solar energy, reflecting the country's growing renewable energy market.
• United Arab Emirates: Dubai's second solar auction set a global record with USD 29.9/MWh, while Abu Dhabi's auction offered USD 24.2/MWh.
• Zambia: Organised its first solar auction under the Scaling Solar programme, achieving a new price record for utility-scale solar in Africa.

4. Emerging Technologies

• Offshore Wind: Auctions for offshore wind were conducted in several countries, including the Netherlands, Denmark, and the UK, with the UK setting a record low price of GBP 49.4/MWh.
• Bioenergy: Bioenergy auctions were held in Argentina, Peru, and the UAE, with the report highlighting the importance of policy support and technology-specific incentives.

5. Key Considerations in Auction Design

• Technology Neutrality: Auctions that allow multiple technologies to compete can lead to more competitive pricing and greater market efficiency.
• Payment Security: Mechanisms such as payment security guarantees, viability gap funding, and contract for difference (CfD) structures are essential in ensuring investor confidence.
• Local Content Requirements: These can influence the competitiveness of bids and the overall economic impact of the projects.
• Regulatory Framework: A clear and stable regulatory environment is critical for the success of renewable energy auctions.

Conclusion

IRENA's report underscores the effectiveness of renewable energy auctions in achieving cost reductions and promoting sustainable energy development. It highlights the importance of well-designed auction mechanisms, supportive policies, and a stable financial environment in ensuring the success of these initiatives. The analysis serves as a valuable resource for policymakers aiming to implement and refine auction-based renewable energy procurement strategies.
