2016 Renewable Energy Auctions Summary

Core Content

This document provides an in-depth analysis of renewable energy auctions held or announced in 2016, focusing on price trends, auction design elements, and country-specific experiences. It highlights how auctions have become a preferred method for governments to procure renewable energy, offering competitive pricing and a more transparent and efficient mechanism compared to traditional support schemes like feed-in tariffs.

Main Trends in Renewable Energy Auctions

• Global Adoption: The number of countries using auctions for renewable energy procurement increased significantly, from 6 in 2005 to at least 67 by mid-2016.
• Competition and Cost Reduction: Auctions have driven down prices for solar PV and wind energy due to increased competition and falling technology costs.
• Technology Neutrality: Many countries implemented technology-neutral auctions, allowing a variety of renewable technologies to compete, while others used technology-specific approaches.
• Investor Confidence: Auctions offer more secure investment conditions than feed-in tariffs, as they typically involve legally binding contracts, reducing the risk of retroactive changes.
• Policy Integration: Auctions are often combined with other policy instruments such as feed-in tariffs, green certificates, and local content requirements to support renewable energy development.

Key Price Trends

Solar PV

• Global Decline: The global average solar PV price dropped from USD 250/MWh in 2010 to USD 50/MWh in 2016.
• Record Low Prices: Several countries achieved record-low solar prices:
  • India: Solar prices fell to INR 2.44/kWh (USD 38/MWh) at Bhadla Solar Park.
  • Mexico: USD 27/MWh was recorded in the second solar auction, setting a Latin American record.
  • United Arab Emirates (UAE): Dubai's second solar PV auction resulted in USD 29.9/MWh, the lowest in the world at that time.
  • Morocco: The first solar PV auction in the country set a new price record for Africa with USD 60.2/MWh.
  • Denmark: Solar power auction set a new price record of USD 19.19/MWh, tied to future wholesale price estimates.

Onshore Wind

• Global Decline: Onshore wind prices have also declined, though at a slower rate than solar.
• Record Low Prices: Several countries achieved record-low wind prices:
  • Chile: USD 37.8/MWh for solar and USD 45.3/MWh for wind.
  • Morocco: USD 30/MWh for wind power.
  • Peru: USD 36.8/MWh for wind, the lowest in Latin America.
  • Germany: Prices dropped by over 20% in one year, reaching EUR 69/MWh.
  • United Arab Emirates: USD 24.2/MWh for 1.17 GW of wind capacity in Abu Dhabi.

Factors Influencing Auction Prices

1. Access to Finance and Country-Specific Conditions:

   • Countries with strong financial systems and stable economic environments are more likely to achieve competitive auction prices.
   • Economic downturns can lead to underbidding, which may result in underbuilding or projects being unviable.

2. Investor Confidence and Conducive Environment:

   • A stable regulatory framework and supportive policies increase investor confidence.
   • Clear rules and transparent processes are crucial for attracting private investment.

3. Policy Support for Renewable Energy:

   • Policies such as feed-in tariffs, green certificates, and subsidies play a role in shaping auction outcomes.
   • Support mechanisms like viability gap funding (VGF) and capacity payments help ensure project bankability.

4. Auction Design Elements:

   • The structure of auctions, including demand bands, price ceilings, and contract terms, significantly affects the final price.
   • The use of payment security mechanisms, such as guarantees, reduces off-taker risk and encourages participation.
   • The inclusion of local content requirements (LCR) can influence the competitiveness of bids.

Country Case Studies

• Argentina: The RenovAr programme saw successful solar and wind auctions, with the second round achieving lower prices than the first.
• Brazil: Continued its renewable energy auctions, with the third round (exclusive to wind and solar) cancelled due to economic recession.
• Chile: Organized one of its largest energy auctions, contracting 23% of the country's projected energy demand for the next decade.
• Germany: Implemented a series of solar auctions, leading to significant price reductions and a shift from feed-in tariffs.
• India: Conducted multiple solar and wind auctions, achieving record-low prices and demonstrating the effectiveness of auction mechanisms in driving down costs.
• Mexico: Two auctions in 2016 resulted in some of the lowest prices in Latin America, linked to the country's reformed electricity market.
• Peru: Set new records for wind and solar prices, showing the potential of auctions in emerging markets.
• United Arab Emirates: Dubai's solar PV auction achieved the lowest global solar price at the time, while Abu Dhabi's wind auction also saw competitive pricing.
• Zambia: Organized its first solar auction under the Scaling Solar programme, setting a new price record for utility-scale solar in Africa.

Technologies in Focus

• Offshore Wind: Several countries, including the Netherlands, Denmark, and the UK, conducted offshore wind auctions, with record-low prices in some cases.
• Biomass: Biomass auctions were held in countries like Argentina and Peru, and the report discusses the challenges and opportunities for deploying this technology.
• Solar Thermal: The UAE's Dubai auction included solar thermal projects, showing the diversification of renewable technologies in auctions.

Key Considerations in Auction Design

• Transparent and Competitive Bidding: Ensuring a fair and open bidding process is essential for attracting bidders and achieving competitive prices.
• Legal and Contractual Security: Legally binding contracts and clear terms help secure investor confidence and reduce the risk of policy changes.
• Payment Security Mechanisms: Techniques such as guarantees and payment security help mitigate financial risks for both developers and off-takers.
• Local Content Requirements: These can influence the competitiveness of bids and promote domestic industry development.
• Price Correction and Inflation Indexing: Adjusting prices for inflation and using local currency conversions can affect the final price outcomes.
• Policy Integration: Combining auctions with other policy instruments can enhance their effectiveness and support long-term renewable energy development.

Conclusion

2016 marked a significant year for renewable energy auctions, with many countries achieving record-low prices for solar PV and onshore wind. These outcomes have set new benchmarks for future auctions and demonstrated the effectiveness of competitive bidding in driving down costs. The success of auctions in various regions, even those with less mature renewable energy sectors, highlights their potential as a universal procurement tool. Understanding the factors that influence auction prices and designing auctions with transparency and investor security in mind is crucial for the continued success of renewable energy auctions.
