Project Guarantees for AI Data Centers: DSRA, Demand Guarantees, LCs and Completion Support

AI infrastructure is creating project-finance exposures at a scale that conventional corporate facilities were not designed to absorb. The Lawrence Berkeley National Laboratory 2025 Update, published in June 2026, estimates a reference case of 649 TWh of U.S. data-center electricity consumption in 2030. Its scenario range is 521–843 TWh, equivalent to approximately 9.5%–15.3% of total U.S. electricity consumption.

Globally, the International Energy Agency projects data-center electricity demand at roughly 945 TWh by 2030, with consumption growing around 15% annually from 2024 to 2030. Electricity used by accelerated servers—principally associated with AI workloads—is projected to grow at roughly 30% per year.

The Financing Problem Starts Before the Servers Arrive

The Federal Energy Regulatory Commission has been addressing large-load interconnection as a distinct infrastructure issue. Its current large-load interconnection proceeding uses loads above 20 MW as a reference point. FERC data also show average data-center projects entering service increasing from approximately 25 MW in 2020 to almost 80 MW in 2025.

That scale creates liabilities before commercial operation. Developers may post security for grid upgrades, transformers, substations, PPAs, equipment reservations, land obligations and construction contracts while the project company itself has little operating history. A lender therefore underwrites both the future cash flow and the mechanisms available when the timetable breaks.

The Credit-Support Stack

1. Completion Guarantees Protect the Construction Loan

During construction, the project has not yet demonstrated operating cash flow. Senior lenders may therefore require the sponsor or an acceptable parent to support cost overruns and provide enough additional capital to achieve defined completion tests.

Completion should be objective. Tests can include mechanical completion, energization, availability of contracted MW, acceptance of electrical and cooling infrastructure, achievement of required PUE or operational parameters, delivery of the contracted IT capacity, absence of material contractor claims and satisfaction of performance tests. The guarantee then burns off when those conditions are achieved rather than remaining an indefinite corporate guarantee of the project debt.

2. The DSRA Buys Time When CFADS Falls Short

A Debt Service Reserve Account is controlled liquidity reserved for scheduled principal and interest. The World Bank's project-finance guidance describes the DSRA as an account intended to protect debt service when project cash flow is temporarily insufficient.

Six months of debt service is a familiar project-finance reference point, but it is not a universal requirement. AI data-center lenders can size the reserve against scheduled debt service, commissioning risk, customer ramp, power-delivery uncertainty and the volatility of contracted versus merchant revenue.

That substitution matters. Every dollar trapped in a reserve account is a dollar unavailable for additional electrical infrastructure, cooling, fit-out, GPUs or contingency. The lender, however, will only recognize an LC substitute after underwriting the issuing bank, expiry mechanics, automatic extension provisions, draw conditions and the relationship between the instrument and the loan maturity.

3. Demand Guarantees Address Performance Risk

A demand guarantee creates an independent payment undertaking from a guarantor, generally a bank. Under ICC URDG 758, a compliant demand is examined under the guarantee itself rather than requiring the beneficiary to litigate the underlying EPC dispute before seeking payment.

For an AI campus, the relevant guarantees may sit behind the EPC contractor, electrical contractor, cooling package supplier, substation contractor or another critical-path provider. Performance guarantees, advance-payment guarantees and warranty-period guarantees therefore protect different stages of the construction programme.

4. Letters of Credit Are Becoming Power Infrastructure

A developer seeking 100 MW, 300 MW or more cannot treat the power contract as a normal utility account. Transmission upgrades, interconnection works, dedicated generation, capacity reservations and long-term energy procurement expose counterparties to material costs before the campus begins consuming at full load.

The utility or power counterparty can therefore require a bank-issued LC covering a defined portion of that exposure. Financely covers the mechanics in its Data Center Power Letter of Credit Financing practice and its guide on data-center LC facilities.

The project must account for this facility as contingent bank exposure. A USD 50 million LC may not require a USD 50 million cash outflow on issuance, but the issuing bank has still placed USD 50 million of its balance sheet behind the applicant. The reimbursement agreement, collateral package, LC sublimit and draw risk therefore matter to the broader debt-capacity analysis.

5. Standby LCs and Demand Guarantees Are Similar Economically, Not Legally

A financial standby LC and an independent demand guarantee can both shift a defined exposure from the project company toward an acceptable bank. They are not identical instruments.

Standby letters of credit are commonly structured under ISP98 or, in some transactions, UCP 600. Independent demand guarantees are commonly issued subject to URDG 758. The beneficiary, jurisdiction, underlying contract, expiry regime, presentation requirements and bank practice should determine the instrument—not whichever acronym appears easiest to obtain. Financely's bank guarantee and standby support practice addresses these instruments as part of the underlying financing requirement.

An Illustrative 250 MW AI Campus

Consider an illustrative project financed through a dedicated SPV. The figures below are not market quotations; they show how several instruments can coexist inside one financing.

The result is not simply USD 1.2 billion of debt. It is a coordinated package of funded senior capital, contingent sponsor capital, reserve liquidity and third-party bank undertakings. Each instrument is allocated to the party best positioned to absorb the relevant risk.

Guarantees Should Burn Off as the Project De-Risks

Strong project-finance documentation does not leave every guarantee outstanding until final maturity. Credit support should track the risk curve.

The Market Is Already Financing the Build-Out

Institutional capital is moving into the sector. In 2026, IFC disclosed a financing package of up to USD 170 million for a data-center development pipeline in the Philippines, including up to USD 150 million of long-term senior loans and USD 20 million of quasi-equity. The capital is available. The underwriting question is whether each project's contractual, construction, power and liquidity risks can be allocated in a form senior lenders can accept.

Structure the Guarantee Around the Risk

A request for a “USD 50 million SBLC” says very little to a project lender. A bankable request identifies the underlying obligation, beneficiary, maximum exposure, draw event, required tenor, expiry mechanics, issuing-bank criteria, collateral source and the point at which the instrument can be reduced or released.

This is also the approach reflected in World Bank project-finance guidance, which identifies reserve accounts, sponsor support, parent guarantees, performance security, insurance, direct agreements and step-in rights as components of the lender security package.

Financely provides structured finance and bank-instrument advisory services. Financely is not a bank or direct lender and does not itself issue guarantees, letters of credit or commit lender capital. Financing, guarantee issuance and facility terms remain subject to underwriting, KYC, AML, sanctions screening, beneficiary requirements, definitive documentation and final credit approval.
