GOVERNMENT-BACKED OFFTAKE GUARANTEES

Lever last updated: 10 September 2026

A public backstop that pays suppliers if a private buyer fails to honour its removal purchase contract.

Cost

Very low to High

Guarantors pay staff and claims, while reserves tie up public money. A 5% reserve holds EUR0.5 million against EUR10 million covered, or EUR100 million against EUR2 billion.

Complexity

Medium to High

An existing public bank may issue one guarantee under current powers. A standing facility needs legislation, CDR eligibility and verification, application and claims data, foreign-buyer rules, enforcement, repayment collection and coordination.

Timeline

Very short to Medium

In September 2020, the World Bank approved a guarantee for payments owed by Uzbekistan’s state electricity buyer. Three months later, the solar developer signed the project’s loan and guarantee agreements. That fast result concerned one ready project under an existing institution. A reusable CDR programme must first establish authority, reserves, eligibility and claims procedures, so its first guarantee may take two to five years to affect financing.

Overview

An offtake contract is a long-term agreement under which a buyer promises to purchase future removals. A government-backed offtake guarantee promises that a public fund or development bank will pay the supplier if that buyer fails to make a contracted purchase or will arrange a replacement buyer on predefined terms. This makes the contracted income more dependable to lenders and can help projects secure finance. Unlike public procurement, government is not the normal buyer. Unlike a contract for difference, it does not guarantee a target carbon price. It responds only to specified buyer failure.

Key Considerations

Coverage must state which buyers, removal methods, contracts, payment failures and years qualify. Government may cover all missed payments or only a share, and may charge the buyer a fee, require security or set a waiting period before paying. Claims should cover only independently verified tonnes, with remedies when removal is not delivered or stored carbon is later reversed. The guarantor also needs limits for projects and the portfolio, checks on buyer and supplier finances, rights to recover payments or take over the contract after a claim, treatment of other public support, and enforceable terms for cross-border contracts and currencies.

Opportunities

Many CDR projects need loans to build. Before lending, banks ask whether the project's future buyers are likely to honour their contracts. A public guarantee can make that income more dependable by paying the supplier if a covered buyer fails. This can help the supplier borrow more, pay less interest or secure all the funding needed to begin construction sooner. It may also allow smaller or newer buyers to join a multi-buyer contract without placing the whole project at risk.

Risks

A payment guarantee cannot rescue a project unable to build or deliver because it covers buyer non-payment, not supplier failure. A replacement buyer can preserve a temporary outlet, but not create lasting demand if no commercial buyer returns. Weak checks can shift foreseeable losses onto taxpayers, while unclear triggers can delay cash. Simultaneous failures may exhaust the fund. Full coverage can weaken contract screening, while scarce support may go to projects that could finance themselves.

Monitoring and Evaluation

Monitoring & Evaluation: The public guarantor should compare contracts signed, guaranteed tonnes, contract length, private finance raised and time to secure full project finance against similar unsupported projects. It should also publish premiums, exposure, buyer concentration, verified delivery, claims, recoveries and reversals. Rising defaults or weak additional investment should trigger tighter eligibility, higher fees, lower coverage or suspension of new guarantees.

Stakeholder Engagement

Before designing support, the treasury or public bank should ask suppliers which viable projects cannot secure loans. Lenders could help identify what coverage and contract length would change financing decisions. Buyers can describe and validate assumptions around feasible commitments.

Governance Levels

InternationalSupranationalNationalRegional / StateCity / Municipal

International development banks can provide payment guarantees, while supranational funds, national treasuries, regional governments and cities can guarantee eligible purchase contracts where their financial law permits. The mechanism is the same at every level, but scale and fiscal capacity differ. Cities and regions are best suited to individual local projects. Larger institutions can spread risk across more buyers and projects. A larger institution may also reimburse part of a smaller guarantor's losses.

Implementation Strategies

  • The public bank should confirm whether buyer failure, rather than construction, delivery, price or storage problems, blocks a viable project.

  • It should then choose a payment guarantee or temporary replacement-buyer facility and decide which buyers and contracts qualify.

  • Rules should state the largest public payout, what cash or assets the buyer must pledge, when payment occurs and how government will seek repayment.

  • Applications should pass financial, technical and CDR-integrity checks. The guarantor should publish claims, losses and repayments before expanding.

Case Studies

ATIDI Regional Liquidity Support Facility

In 2017, the African Trade and Investment Development Insurance Agency and Germany's KfW Development Bank launched this facility for renewable-power companies selling electricity to state utilities. If a utility misses an eligible payment, the power company can claim from ATIDI after a waiting period. ATIDI pays and then seeks reimbursement from the utility through its finance ministry. By December 2025, the operating facility had issued nine guarantees supporting projects that secured all financing needed to begin construction. It shows how a standing payment guarantee can work across countries, but it concerns renewable electricity, not CDR.

United Kingdom Offtaker of Last Resort

The United Kingdom created this backstop in October 2015, but it has never been used. If an eligible company selling renewable electricity cannot find a normal buyer, Ofgem checks the application and runs an auction among large electricity suppliers for a one-year purchase agreement. The winning supplier temporarily buys the electricity at a deliberately discounted price. Ofgem’s October 2025 report says no one had ever applied and no agreement had been signed. The case shows how a replacement buyer can be kept ready, but gives no evidence of use, financing effects or CDR implementation.

World Bank guarantee for the Navoi solar project

Uzbekistan's state-owned grid company and Masdar signed a 25-year electricity contract in November 2019. Natixis Bank issued a US$5.1 million letter of credit, meaning it would pay Masdar's project company if the grid company did not. If Uzbekistan failed to repay Natixis within twelve months, the World Bank's 20-year guarantee would reimburse the bank. The project secured all construction funding in December 2020, mobilised about US$110.9 million and began operating in December 2021. No guarantee payment was reported through December 2023. This renewable-electricity examples demonstrates a two-stage payment guarantee, not CDR evidence or proof that the guarantee alone caused investment.
