Southeast Energy Authority

What Southeast Energy Authority does

Southeast Energy Authority (SEA) is an Alabama public corporation and capital improvement cooperative district, formed in 2019 as part of the Southeast Gas family of Alabama public corporations that originated in 1952. SEA operates as a wholesale supplier of long-term, discounted natural gas and electricity to tax-exempt, municipally owned gas and electric systems located within Alabama and across the United States. It executes its core function through prepaid energy transaction structures financed via municipal revenue bonds (e.g., Series 2025H and the $760.6M October 2024 issuance), which it uses to purchase physical energy commodities and resell them to member municipalities and other governmental wholesale customers at below-market rates.

SEA's product portfolio includes single-commodity natural gas prepay, electricity prepay, and hybrid gas/electric prepay structures, with a switch flexibility option allowing participants to convert from gas to electricity deliveries at a designated date. In October 2022, it closed what it describes as the first-of-its-kind transaction incorporating all three commodity options — natural gas, electricity, and switch flexibility — alongside earlier transactions for Salt River Project (April 2021 hybrid) and nine gas participants (June 2021). From 2021 through October 2024, SEA executed eight prepayments totaling $4.71 billion, with additional $783.4M (September 2025) and planned $600M (2025) issuances. It currently delivers an average of 94,430 MMBtu per day and 31,100 MWh per month at 13 delivery points servicing 19 municipalities across 15 states.

SEA is owned and governed by 14 Alabama municipalities plus a 15th board seat for the City of Troy, Alabama, with each member appointing a designated representative. Its named participants include Salt River Project, Long Island Power Authority, UAMPS, Huntsville Utilities, Decatur Utilities, Richmond Gas Works, Philadelphia Gas Works, Jackson Energy Authority, and the City of Tallahassee. The company's revenue model is transaction-based, capturing the spread between bond-financed prepay commodity purchases and resale to members, plus structuring fees. Counterparty financial partners include Goldman Sachs, Morgan Stanley Energy Structuring LLC, and Royal Bank of Canada, with Orrick Herrington & Sutcliffe (tax counsel), McCarter & English (energy counsel), Chapman and Cutler (bond counsel), and Municipal Capital Markets Group (financial advisor) supporting the legal and capital markets infrastructure.
