Allianz SE (ALV.XE), Europe's biggest insurer by market value and a major asset manager, is "closely eying" investments in offshore windparks, and individual investments could amount to up to 1 billion euros ($1.3 billion), provided several conditions are met, Chief Financial Officer Oliver Baete said Wednesday.

So far, Allianz has only invested in onshore windparks. It currently owns 34 wind farms and seven solar farms in France, Germany and Italy. Allianz's total investment is about EUR1.3 billion in renewable energy, which it considers a growth market.

Mr. Baete's comments reflect heightened interest in offshore wind energy as in June Allianz only said it was "open for investments in offshore wind," but that it hadn't so far found a suitable opportunity where the return outweighed the long-term risk involved.

Speaking at a press club in Munich, Mr. Baete said a lot of progress has been made in clarifying liability issues for offshore wind energy investments, and once the issues are cleared, Allianz would be "ready to invest."

Once the risk-return profile is appropriate, regulatory issues are clear and cluster risks can be avoided, Allianz could consider a bigger individual investment, up to EUR1 billion, Mr. Baete said. However he added that the company would prefer to take on the investment as part of a consortium. He declined to comment on when Allianz could make its first investment in offshore wind energy.

Germany's government hopes that insurers will become a big financial investor in its post-nuclear energy strategy. The financing gap for the switchover to renewable energies has been estimated at around EUR250 billion. In 2020, the strategy stipulates that offshore wind parks contribute about 10,000 megawatts of power capacity. This is equivalent to around 10 nuclear plants and is an ambitious target.
