Solutions Center - Background and Vision

The Solutions Center: Is one of several CEM Initiatives, which include:

− Global Superior Energy Performance Partnership

− Super-Efficient Equipment and Appliance Deployment initiative

− Global Lighting and Energy Access Partnership

Helps governments design and adopt policies and programs that support the deployment of clean energy technologies

Has more than 35 partners, including IRENA, IEA, IPEEC, Sustainable Energy for All, Bloomberg New Energy Finance and Leonardo Energy

Is co-chaired by the U.S. Department of Energy and the Australian Department of Industry.

RE Auctions world wide

• RE auctions: from 7 countries in 2005 to 60 countries in 2015

Source: IRENA 2015, REN21 2005, REN21 2015

Designing auctions: Key questions for policymakers

Key questions when designing auctions of RE

1. What is being auctioned and when? (Procurement schedule)

2. Who can participate in auctions? (Pre-qualifications) 3. On what basis are bid evaluated? (selection criteria) 4. What mechanisms is used for price determination? (Price-finding

mechanism) 5. What payment will winners receive? (payment modalities) 6. How can I assure that projects will actually get built? (Penalties for

none-compliance)

Procurement schedule: What is being auctioned and when?

• Scale of auction (MW)?

• Technology neutral versus technology-specific auctions? • Frequency of auction rounds?

• Upper or lower limit on project size?

• Upper or lower limit on prices?

Procurement schedule

Pre-qualifications: Who can participate in auctions?

• Prequalification requirements for auctions – important for project realization rate!

Pre-qualifications

Material pre-qualifications Financial pre-qualifications

Grid access and connection Bid bonds Securitization of land Demonstrate financial strength

Contracts for equipment Project finance track-record

Permits

Selection criteria: On what basis are bids evaluated?

• Lowest bids/prices

• Primary objective of auctions

• Lowest bids/prices plus X

• Additional selection criteria usually reflect additional

policy objectives:

• Job creation

• Local content

• Locational incentives

• Etc.

Selection criteria

Payment modalities: What payment will winners receive?

• Pay-as-bid

• Minimize costs

• Take resource variations into account

• Marginal cost payment

• Same price for all winners (highest cost winner determines

price)

• Avoid “winner’s curse”

Payment modalities

Price-finding mechanism: What mechanisms is used for price determination?

• Sealed-bid auctions

• Simple design – ceiling price?

• Each bidder writes down a single bid which is not disclosed

to other bidders and the most competitive bidders win

(“pay as bid”).

• Decending-clock (Dutch auction)

• Multi-round bid

• Auctioner starts with a high price and then calls out successively

lower prices until quantity offered and quantity required match!

• Hybrid design

Price-finding mechanism

Penalties for none-compliance: How can I assure that projects will actually get built?

• Penalties for failure to fulfil awarded contracts

• No (or only partial) payback of bid bonds or construction

bonds; Completion bonds

• Reduction of tariff payment levels/payment period

• Exclusion from next auction round

• Define maximum lead times

Penalities for none-compliance

Summary: Advantages and disadvantages

Pros and cons of auction mechanisms

Advantages Disadvantages Cost efficiency and price competition High administrative costs (complexity)

High investor security (PPA) Discontinuous market development (stop-and-go cycles)

Volume and budget control risks of not winning project increases finance costs

Predictability of RE-based electricity supply (sector growth)

Risk of underbidding (lack of deployment and target achievement)

Combination with other policy objectives, e.g. local content, etc.

Exclusion of small-scale actors

Auctions and feed-in tariffs: Mutually exclusive or complementary?

• What is being auctioned? • Frequently fixed price contracts (payments per kWh)!!

• In this case, the major difference between FITs and auctions is the

price-discovery mechanism: • Administratively fixed prices (FITs) • Price determination via competitive bidding (auctions)

Auctions versus FITs?

• Do you have experience in setting prices administratively?

• Is there sufficient interest in investing in renewables in your country (competition in Least Developed Countries)?

• Is the market big enough to create competition (size of auction; schedule for auctions)?

• Which type of actors should invest (small vs. big)?

Auctions or FITs: No easy answer…

• Move from FITs to auctions

• Use auctions to determine FIT prices • Use auctions for emerging technologies and FITs for mature

technologies

• Use auctions for large projects and FITs for small projects

Combining FITs and auctions

• Specific auction design for smaller actors?

• Funds for the project development stage

• Lower prequalification criteria for small scale actors (bid bonds)

• Use auction results to determine fixed prices for certain

investor groups?
