A Transforming Energy Landscape
After more than a decade of essentially flat power consumption, the United States is entering a sustained period of rising electricity demand. The buildout of AI and cloud computing infrastructure is the standout driver, compounded by the electrification of vehicles and heating and a resurgence in domestic manufacturing. Estimates of the scale and pace of this shift vary, but the direction couldn’t be more clear: demand is set to climb meaningfully over the next several years, and in some regions, faster than new generation and grid infrastructure can comfortably absorb.Utilities and power developers are responding with one of the largest power generation buildouts in decades. Solar, battery storage, and wind currently account for the bulk of new capacity additions, while natural gas continues to anchor dispatchable supply and remains the preferred fuel that utilities lean on to meet incremental and peak load. Over the longer term, the resource mix is expected to keep shifting toward a blend of natural gas and renewables, as coal continues to retire and the share of nuclear production remains flat.The significant increase in energy demand, paired with a supply mix still in transition, is creating a real budgeting challenge for municipal utilities, which typically lack the tools large corporates use to hedge multi-decade commodity exposure.
Enter Prepaid Energy Bonds to Help Fill the Gap
Faced with a rising and less predictable cost of energy, municipal utilities and public energy authorities have increasingly turned to prepaid energy bonds as a financing tool that allows them to lock in long-term energy supply while leveraging the tax-exempt market to do so at a discount to prevailing market prices. What began as a niche corner of the municipal market has quickly become a structurally important sector, now exceeding 5% of the broad municipal bond index and surpassing $100 billion outstanding, with average annual issuance growth of roughly 30%–40% over the past several years.
What Is a Prepaid Energy Bond?
A prepaid energy bond is a tax-exempt municipal bond whose proceeds are used to make a large upfront (“prepaid”) payment to an energy supplier in exchange for a long-term, typically 25-to-30-plus-year, commitment to deliver natural gas or electricity to a public utility at a fixed, discounted price. In a traditional municipal bond transaction, investors lend money to a governmental entity that finances a public project and uses its taxing power or project revenues to repay investors. Prepaid energy bonds work differently: rather than financing a physical capital project, the bond proceeds finance this long-term energy supply contract. While payment coupon and bond principal is designed to be funded by the economics of that contract, the ultimate credit exposure of the bonds lies with the funding recipient as outlined in the Funding Agreement section below. Funding recipients tend to be investment grade rated, large financial institutions such as banks and insurance companies. Putting it all together, prepaid energy bonds are a bit of a hybrid between municipal and corporate markets as they provide tax-exempt income, support long-term energy supply for municipal utilities, but are ultimately backed by a corporate guarantor.

The Investment Opportunity
What we like about prepaid energy bonds:
1. Yield
Prepaid energy bonds have historically offered incrementally higher yields relative to comparably rated municipal bonds. Often carrying ratings of A to AA+, the additional yield for prepaid energy bonds has been approximately +0.80%.
2. Credit Diversification
With repayment ultimately resting with that of the funding recipient, prepaid energy bonds are really municipal bonds wrapped with a corporate guarantor. Collaborating with our corporate credit analysts, we see this as an opportunity to diversify portfolio credit exposure to include highly rated corporate credits. Examples of common funding recipients include Morgan Stanley (A1), Goldman Sachs (A2), New York Life Insurance Company (Aa1), Pacific Life Insurance Company (Aa3), National Bank of Canada (Aa2), among others.
Key Risks to Monitor
“A prepaid energy bond looks like a municipal bond — but its risk profile is closer to that of the corporate guarantor standing behind it.”

The Payden & Rygel Perspective
A Structural Story, Not a Cyclical One
As prepaid energy bonds grow as a share of the Bloomberg Municipal Bond Index, institutional platforms are becoming more familiar with the sector, driving incremental demand from separately managed accounts and actively managed strategies.
Payden & Rygel actively monitors guarantor differentiation, off-taker concentration trends, and new issuance technicals to identify relative value opportunities. We view the sector’s continued growth as a structural — not cyclical — phenomenon, driven by durable demand for long-term energy price certainty across utilities, industrial customers, and now the data center economy.
For investors equipped to underwrite corporate guarantor credit and structural risk alongside traditional municipal credit work, energy prepay bonds offer a differentiated way to capture incremental tax-exempt yield in an otherwise low-spread municipal market.
