Financing offshore wind


The market to date

Industry growth so far has largely been achieved by utilities, alone or in small partnerships, financing and building their own projects and keeping them on their balance sheet.

There are, however, other possibilities. “Non-utility” projects, undertaken by independent power producers (IPPs), may call on non-recourse debt financing from banks, particularly during the construction phase. As of end 2010, just over 10% of operational capacity (and a similar percentage of capacity under construction) had benefitted from non-recourse debt financing, with a smaller percentage having been refinanced through debt after completion.

A number of interesting conclusions may be drawn at this point. One is that there are alternative sources to utilities for investment in offshore wind. Another is that banks show willingness to take construction risk (via debt), preferably, so far, in non-utility projects. Meanwhile, financial investors (via equity) tend rather to seek a stake in already operational projects. These conclusions also point to the most likely routes for utilities looking for external sources of funding:

  • recycling of project equity via the sale of (typically minority) stakes in operating projects; non-recourse financing of IPP projects prior to completion;
  • non-recourse refinancing of “utility” projects once they are operational.
