Why Data Centers Need Letters of Credit for Power

Securing hundreds of megawatts for a new data center can create substantial credit-support obligations years before the campus reaches full utilization.

Utilities and transmission providers may require collateral before committing generation capacity, grid upgrades, substations and long-term electric service. Letters of credit have become one of the principal instruments supporting those obligations.

Utility Requirements

Power Contracts Create Credit Obligations

A utility serving a hyperscale campus may have to construct substations, expand transmission capacity, secure additional generation and reserve large blocks of electricity for one customer. Those investments can begin well before the data center is operating at its contracted load.

Utilities therefore require developers to demonstrate financial capacity behind their commitments. Depending on the applicant's credit standing and the applicable tariff or contract, acceptable security can include a parent guarantee, cash collateral or a bank letter of credit.

Global Trade Review reported a structural increase in LC usage across data center power procurement and grid interconnection transactions in the United States.

Transaction Mechanics

How a Data Center Power LC Works

The data center developer is the applicant. A bank issues the LC in favor of the utility, transmission provider or other approved beneficiary. The instrument secures defined contractual obligations and remains outstanding for the required collateral period.

The issuing bank assumes contingent exposure. A payment occurs when the beneficiary presents a complying drawing under the LC. The developer remains responsible for reimbursing the issuing bank under the underlying credit agreement.

Applicant

Data center developer, sponsor or operating company requesting issuance.

Issuing Bank

Provides the contingent credit exposure and issues the instrument.

Beneficiary

Utility, transmission operator, generator or contractual counterparty.

Underlying Obligation

Interconnection, power procurement, transmission or electric-service commitment.

Evergreen LCs Match Long Development Timelines

GTR reports that many data center power transactions use evergreen LCs that renew automatically, commonly at one-year intervals. This structure can support utility obligations throughout a multi-year construction and energization schedule while maintaining a defined non-renewal process.

Facility Scale

Large Campuses Can Require Syndicated LC Capacity

Smaller collateral requirements can be handled bilaterally with one bank. Gigawatt-scale development pipelines can require substantially more capacity.

Switch initially arranged a $2.6 billion syndicated performance LC facility to support power procurement, generation and transmission obligations. The facility was subsequently expanded to $3.5 billion.

Large syndicated facilities distribute contingent credit exposure across a bank group and give developers more aggregate issuance capacity across multiple utilities and projects.
