3 Introduction Motivation Renewable energies, and wind energy in particular, are substantial for future power generation The European Union target is to achieve 20% of gross final energy consumption from renewable energies by 2020 The European Wind Energy Association (EWEA) estimates the total investment requirements in European offshore wind from 2013 to 2020 to be approx. 90 to 124 billion USD Private and institutional investors will be the most relevant source of finance Investment risks need to be identified and categorized (quantitatively and qualitatively), as appropriate risk management is of great relevance for investors 3

4 Introduction Aim of paper Aim of this paper Comprehensively present risks of renewable energy projects, particularly for onshore and offshore wind energy Identify critical gaps in risk management instruments Toward this end Comprehensive assessment of the academic literature and several industry surveys Identify and assess relevant risk categories for renewables (wind parks) Present adequate risk management tools to manage the identified risks Identify and discuss challenges (gaps) of risk management 4

5 Risk categorization Selected definitions Proposed categorization based on findings from the literature Strategic and business risks Transport, construction and completion risks Operation and maintenance risks Liability and legal risks Market and sales risks Counterparty risks Political, policy and regulatory risks In particular, several industry surveys find policy and regulatory risks as a major threat for renewable energy investments For offshore wind parks particularly construction risks as well as operation risks are relevant 5

6 Risk categorization Transport, construction and completion risk Relevance for wind parks Risk of start-up delays / advanced loss of profits Grid connection risk Specific considerations for offshore wind parks: Special construction vessels required ( jack up vessels etc.: bottleneck risk): limited availability, possibly booked out for years Requires good weather conditions for foundation and construction Grid connection risk especially relevant in case of offshore wind parks (bottleneck risk) Risk management Insurance: Available for delay in start-up, advanced loss of profit, construction and transportation risks Operation & Maintenance (O&M) contracts (service provider guarantees) Risk avoidance: Risks associated with construction may be avoided by directly investing in already built wind parks Risk management instruments for transport, construction and completion risks are available for onshore, however, partly limited for offshore wind 6

7 Risk categorization Political, policy and regulatory risks Relevance for wind parks Risk of retroactive adjustment of support Future uncertainty regarding prospective policy support or regulatory requirements regarding solvency capital requirements Risk of expropriation or war, e.g., developing countries Risk management Private insurance: Political risk insurance may provide partial cover in case policy change is an expropriate breach of the investor s rights Public insurance: Political risk insurance by MIGA (Multilateral Investment Guarantee Agency; World Bank Group agency): covers only developing economies and emerging markets FiT insurance by OPIC (Overseas Private Investment Corporation; only for US equity holders) Partial risk guarantees by the World Bank Further risk mitigation: Due diligence practices including an assessment of potential future changes in legislation, e.g., by identifying political risk indicators Geographical and regulatory diversification (benefits of scale in risk management) Risk management solutions are available for traditional political risks, however, insufficient for policy and regulatory risks 7

8 Challenges for risk management Availability of selected risk management tools Insurance solutions Insurance for construction and operation life cycle phase is available for onshore; however, limited for offshore wind energy, due to high complexity, multi-contract projects, larger coverage, lack of data, etc. Operation and maintenance service contracts Often applied Full Service Agreements (FSA), e.g. guaranteeing predefined x% wind turbine availability (or guaranteed output) Special solutions Weather-related volume (resource) risk, e.g. Munich Re Lack of Wind Weather-based and energy derivatives, however, exposed to basis risk 8

9 Challenges for risk management Focus on political, policy and regulatory risk Political, policy and regulatory risk Public coverage is available to some extent by MIGA (World Bank; developing countries), OPIC (FiT; US equity holders investing in developing economies) or the World Bank (partial risk guarantees) Private coverage is available for some political risks (e.g. expropriate breach of investor s rights, war, etc.) Investors are in particular exposed to policy and regulatory risks, which are just barely hedgeable Apart from insurance, diversification (by manufacturer, geographically, technologies, and countries / regulations) is primary risk management tool 9

10 Summary Risk management of renewable energies is of great relevance for investors due to various risks (see risk categories) Risk management tools, e.g. insurance is available for a majority of associated risks, however, it is partly limited for some risks (e.g. construction risks offshore, policy and regulatory risks) Concluding: New technologies remain challenging for underwriting and pricing In the long-run, construction risks will decrease with technological progress However, policy and regulatory risks remain relevant for investors 10

11 Outlook Diversification appears to be single risk management tool for policy and regulatory risks in general (except for some public risk management solutions) Thus, policy and regulatory risks are a major threat for renewable energy investments and risk prevention prior to investment is relevant. Future research should therefore focus on Drivers of policy and regulatory risks of renewable energy investments Quantification of policy and regulatory investment risks of renewable energies 11

16 Risk categorization Selected definitions Proposed categorization based on findings from the literature: Risk Subcategory 1. Strategic / business risks Financing risks / insufficient expertise / insufficient public acceptance / complex approval processes / insufficient management know-how 2. Transport / construction / completion Revenue loss due to start-up delay / damage or theft during transport or construction 3. Operation / maintenance a) General operation and maintenance risks / damages / technological and innovation risk b) Revenue loss due to business interruption c) Damage due to natural hazards (severe weather) d) Damage due to serial losses 4. Liability / legal risk Liabilities to third parties / law costs / contracting risk 5. Market / sales risks a) Variability of revenue due to weather / resource risk b) Variability of revenue due to grid availability / curtailment risk c) Variability of revenue due to price volatility 6. Counterparty risk a) Supplier of O&M services b) Counterparty risk Power Purchase Agreement (PPA) 7. Political / Policy / regulatory risks Policy support / Feed-in-Tariff (FiT) changes; uncertainty regarding regulation (e.g., Solvency II and Basel III) 16

17 Risk categorization Strategic and business risks Relevance for wind parks Risk of insufficient access to capital Insufficient acceptance in general public Complex and long approval procedures Specific considerations for offshore wind parks: Approval periods especially long in Germany with years (assessment of environmental sustainability) Risk management Risk mitigation: Adequate communication of project plans / communication strategy to gain social acceptance Establish contingency plans for relevant what if scenarios (see also transport ) Prior to construction: monitor weather to evaluate suitability of a location Risk retention by captive insurance subsidiaries due to information asymmetry regarding risks (insurer estimates risks higher) or in case of hard markets (high insurance prices) 17

18 Risk categorization Operation and maintenance risks Relevance for wind parks Risk management a) General operation and maintenance risks / damage / technological and innovation risk Risk of damage to physical assets Insurance Unavailable resources / replacement Manufacturer warranties / O&M contracts (guarantees by risk service providers) Technological risk Further risk mitigation: Innovation risk implement conditional monitoring system (CMS) and structural health monitoring (SHM) Rely on proven technologies Diversification with regards to the supplier of wind turbines to reduce technical risk (deficiencies) and replacement risks (available resources) b) Damage due to natural hazards (severe weather) Risk of damage due to natural hazards Insurance Further risk transfer: Weather derivatives, Cat Bonds c) Damage due to serial losses Insurance Further risk transfer: Diversification d) Revenue loss due to business interruption Insurance / O&M contracts 18

19 Risk categorization Liability and legal risks Relevance for wind parks Damage to the environment and liability arising from damage Specific considerations for offshore wind parks: Increasing traffic volume on the sea increases liability risk Due to more difficult construction (heavy parts, installation on the sea), higher risk of liability from property damage and bodily injuries of persons Legal contracts often international; need to comply with national law Risk management Insurance: Various liability coverages, also for environmental risks Various coverages for law / legal costs (e.g., in Germany special defense insurance policy for renewable energy by LVM) Risk mitigation: Assure applicability of contracts under national law; extensive due diligence prior to contracting 19

20 Risk categorization Market and sales risks Relevance for wind parks Risk management a) Variability of revenue due to weather/resource risk Revenues vary due to different wind Insurance: speeds (in the US around 15-20% Insurance against climate and weather risks: fixed sum in case year-to-year variability for wind insured event occurs, very flexible, based on index projects depending on region, only 5% in the case of solar), while debt has to be paid regularly: need a Guarantees by service providers (full service agreement) minimum debt service coverage ratio Further risk mitigation: Diversification Further risk transfer: Energy derivatives b) Variability of revenue due to grid availability / curtailment risk Curtailment risk / grid availability Risk mitigation: Diversify power generation portfolios Risk transfer: Sign power purchase agreements c) Variability of revenue due to price volatility Markets without support schemes Risk transfer: are exposed to general fluctuations Energy derivatives (forwards) of energy prices 20

21 Risk categorization Counterparty risk Relevance for wind parks a) Supplier of O&M services Financial stability of supplier of operation and maintenance (O&M) services is critical Specific considerations for offshore wind parks: Counterparty risk of major suppliers / contractors considerable issue for offshore wind parks, where financial strength concerns contract fulfillment, as well as guarantees / warranties b) Counterparty risk PPA Counterparty risk of buyer in case of a power purchase agreement (US, UK) Risk management Risk transfer: Counter-guarantee against default of loan by public bank (required by institutional investors to invest in offshore wind parks, e.g., Northwind project in 2012 with Pension Denmark) Risk mitigation: Use experienced developers and suppliers with strong credit rating and performance track record (reputable contractors), especially relevant for offshore wind parks (high entry barriers to supply chain), as well as long-term contracting Sign reserve contract with other suppliers in case of a financially unstable O&M supplier Risk mitigation: Use reputable contractors 21
