Il settore delle energie rinnovabili deve migliorare il risk management. Rischi crescenti e necessità assicurative

The renewable energy sector needs to improve risk management and access alternative sources of capital as operational risks rise and governments cut funding due to the uncertain economic environment.

Based on a survey of 284 senior-level renewable energy executives, a new report by the Economist Intelligence Unit (EIU) and sponsored by Swiss Re canvasses the risks in financing, constructing and operating renewable energy projects as well as the risk management challenges that the renewable energy industry must confront.

The EIU report “Managing the Risk in Renewable Energy” maintains that the renewable energy sector may face an even more uncertain future if it fails to manage the growing risks associated with larger and more complex projects.

Cuts in government expenditures for the sector call into question the sustainability of public financial support for renewable energy developments, especially in Europe, according to the report. Cuts in solar feed-in tariffs range from 15 percent in Germany to 70 percent in the UK. Investors in renewable energy worry that some of the other 100 or so governments supporting clean-energy investments will cut this support as part of austerity measures, the report suggests.

“Additional investments into renewable energy are needed to achieve the transition to a low-carbon economy,” said Agostino Galvagni, chief executive officer Swiss Re Corporate Solutions. “Risk management measures such as insurance will be key to encourage further private sector investment.”

A major issue in renewable energy projects is their costliness in the early stages. The projects are often capital-intensive and highly leveraged, with up to 70-80 percent financed through debt. As companies seek to scale up investments, overcoming financial risks is one of the biggest challenges, according to 76 percent of the survey respondents.

Beyond financial risk, a significant concern for plant investors, owners and operators is political and regulatory risk (62 percent) while weather-related volume risk comes in third for wind power producers (66 percent). These risks increase further as projects grow in scale and complexity.

However, only 50 percent of respondents said they are successful at transferring risks, for example through insurance. Many retain the risks related to renewable energy assets on their balance sheets – for instance weather-related volume risk – due to the limited availability of suitable risk transfer mechanisms.

“New technologies and innovation in renewable energy will be the only possibilities left should a global policy regime to reduce carbon emission not materialise,” said Andreas Spiegel, Swiss Re’s senior climate change adviser.

Spiegel said  Swiss Re is investing in research to better understand how insurance can mobilize financing for renewable energy projects and identify the most cost-effective ways to reduce risks, such as construction and operational risks as well as risks related to the intermittent nature of renewable energy production.

Insurance Demand

Some 60 percent of respondents said they already use insurance to transfer risks. As the demand for insurance grows, new products, including alternative risk transfer solutions, are starting to appear on the market, according to Swiss Re’s report.

The use of solutions such as weather-based financial derivatives is slowly picking up, but still only 4 percent of wind power producers apply them to their projects.

The  report says that many solutions on the market today are unsuitable for small-scale projects. Executives say they would transfer more risk if suitable risk transfer products become more widely available in the future, particularly more standardised and cost-effective products.

Swiss re said it offers “tailored solutions” covering production and price risk for hydro power producers and plans on expanding its product offering into wind and solar power projects.
