Utility revenue bonds are a specialized type of municipal bond issued to finance public utility projects. Unlike general obligation bonds, these bonds are repaid from the revenue generated by the utility project, such as a water treatment facility or power plant, rather than from tax revenues.
Definition and Mechanisms of Utility Revenue Bonds
A utility revenue bond is distinct in its repayment structure:
Key Characteristics
- Revenue Source: Repayment is sourced directly from the income generated by the public utility project.
- Project-Specific: Funds are earmarked for specific projects, making them attractive for targeted infrastructure improvements.
- Risk Profile: Generally considered riskier than general obligation bonds since repayment depends on the project’s success.
Formula and Financial Structure
The bond’s financial structure can be represented as follows:
where:
- \( R_{UB} \) is the revenue required to repay the bond.
- \( C_t \) is the cash flow generated by the utility project at time \( t \).
- \( r \) is the discount rate.
- \( T \) is the term of the bond.

Historical Context and Evolution
Utility revenue bonds have been a vital financing tool for public infrastructure since the early 20th century. Their popularity surged with the increasing need for modern utilities and the desire to offload the financial burden from taxpayers.
