In this article:

The renewable energy sector has been growing rapidly over the past few years, with offshore wind energy taking center stage.

Wind power projects have become an increasingly popular form of financing, and many expect the sector to continue to grow.

In this article, we will examine offshore project financing and the various project finance models and debt structures used to provide capital to the development of such projects.

Additionally, we will discuss the benefits and risks of offshore wind project financing, including options for large-scale offshore wind projects in the US, due diligence considerations, and other key issues in offshore wind project finance.

What is offshore wind farm financing?

Definition of offshore wind farming

Offshore wind farming refers to the construction of an offshore wind project, which involves the installation of wind turbines in bodies of water.

Unlike onshore wind projects, offshore wind projects are usually located far from the coast, in deeper waters where wind speeds tend to be higher and more consistent.

Offshore farms provide renewable energy that can be used to power homes and businesses, and the electricity generated can be sold to utilities or other purchasers.

Project finance models for offshore wind farming

Offshore financing is used to fund the development of offshore wind projects. It is typically used for providing capital to large-scale capital-intensive projects, such as offshore wind projects.

These models involve a complex financial structure with various sources of capital, including equity, debt, and tax equity.

Benefits and risks of offshore wind farm financing

The benefits of offshore wind farm financing include the potential for significant returns and the ability to finance large-scale renewable energy projects.

However, it also comes with associated risks, including regulatory hurdles and the high capital costs involved in developing the projects.

As a result, investors and lenders must carefully evaluate these risks and develop a comprehensive financial structure to mitigate them.

How to finance an offshore wind project?

Equity capital for offshore wind

Equity financing is one of the most common forms of financing for offshore wind projects.

Equity capital involves raising capital by selling shares in the project to investors.

Equity can be a high-risk investment due to the project's long-term nature, but it can also provide significant returns if the project is successful.

Tax equity financing for wind energy

Tax equity financing is an option that provides investors with tax credits in exchange for investing in renewable energy projects.

It has become increasingly popular in recent years as a way to fund large-scale renewable energy projects.

Project finance and debt structuring for offshore wind projects

Project finance and debt structuring are used to finance offshore wind projects that require large amounts of capital.

Project finance typically involves raising debt from commercial banks or other lenders to fund the project's construction.

Debt structuring involves dividing the debt among multiple lenders and developing a repayment structure that is tailored to the project's financial needs.

Why invest in offshore wind farming?

The growth of the offshore wind energy sector

The offshore wind energy sector is expected to grow significantly over the next few years.

The US Department of Energy has set a target of 30 GW of installed offshore wind capacity by 2030, which would require substantial investment in offshore wind projects.

The investment tax credit for offshore wind energy projects

The investment tax credit (ITC) is a federal tax credit that provides incentives for renewable energy investments.

For offshore wind projects, the ITC provides a tax credit of 12% of the project's eligible costs. This tax credit has helped to incentivize investment in offshore wind projects.

The cost of offshore wind energy

The cost of offshore wind energy has been decreasing in recent years, making it more competitive with other forms of energy.

As technology improves and economies of scale are achieved, the cost of offshore wind energy is expected to continue to decrease, making it an increasingly attractive investment.

Financing options for large-scale offshore wind projects in the US

Export credit agency financing

Export credit agency financing involves money from government agencies that provide support for US companies exporting goods and services.

It can be useful for supporting US offshore wind developers who are exporting offshore wind technology and services.

Commercial bank products

Commercial bank financing is one of the most common forms of funding for large-scale offshore wind projects in the US.

Commercial banks provide project finance and debt structuring to help fund the construction of offshore wind projects.

Utility financing

Utility financing involves capital from utilities that purchase the electricity generated by offshore wind projects.

It can be particularly useful for smaller offshore wind projects that may not be able to access commercial banks or export credit agency products.

Private Debt Project Funding

Private debt project funding for offshore wind projects involves securing non-bank loans from private investors to finance the development and operation of wind farms at sea.

This financing approach provides flexible capital solutions tailored to the specific needs and risk profiles of offshore wind energy projects, enabling their advancement in the renewable energy sector.

Due diligence considerations and other key issues in offshore wind project finance

Supplier and turbine selection

The selection of suppliers and wind turbines is a critical aspect of offshore wind project capital.

Investors and lenders must carefully evaluate the suppliers and turbines to ensure that they are of high quality and capable of producing the desired amount of electricity over the project's lifespan.

Cash flow modelling and Debt Service Coverage Ratio (DSCR)

Cash flow modelling and debt service coverage ratio (DSCR) are critical components of offshore wind project finance.

Cash flow modelling involves developing a financial model that predicts the project's revenue and expenses over time, while DSCR involves measuring the project's ability to generate cash flow to service its debt.

Reaching financial close and pre-agreed terms

Reaching financial close and pre-agreed terms are also important considerations in offshore wind project capital.

Financial close refers to the point at which all capital has been secured, and the project is ready to commence construction.

Pre-agreed terms refer to the terms and conditions that have been agreed upon by all parties involved in the project finance process.


Offshore wind farm financing is an essential part of the renewable energy industry, providing a means to provide capital, and maintain, and develop offshore farms.

These models are often used for this type of capital project, and there are a wide range of funding options available.

Investors and lenders must carefully consider key issues such as due diligence, cash flow modelling, and supplier selection to ensure the success of offshore wind projects.
