Risk-sharing guarantee facilities for flexibility and distribution portfolios
Risk-sharing guarantee facilities structured as first-loss windows provide an alternative financing approach to traditional utility capital budgeting, asset-backed lending or project-by-project guarantees. Distribution level flexibility programs have historically struggled to scale because assets are small, heterogeneous, and operationally uncertain, characteristics that conventional lenders often price as high risk, limiting deployment.
First-loss portfolio guarantees address this challenge by shifting a defined share of early losses away from private investors and allowing diversified portfolios of distributed flexible assets to be financed under a single risk framework. By aggregating assets with different performance profiles, these facilities reduce overall portfolio risk and enable financing structures that are more compatible with digital, service-based grid solutions than legacy funding approaches.
The International Energy Agency’s (IEA) World Energy Investment 2025 report highlights that investment in distribution networks and flexibility solutions has not kept pace with rising system needs as electrification accelerates.[1] Guarantee facilities help address this gap by improving bankability, lowering the weighted average cost of capital and increasing the leverage of private capital. By reducing investor exposure to early losses, these structures allow utilities, DSOs, TSOs, and aggregators to deploy flexibility and grid support programs at a scale that has been difficult to achieve through conventional mechanisms.
Main outcomes of the solution
- Reliability & Flexibility: Faster deployment of aggregated flexible assets such as demand response, distributed storage and digital grid services, supporting peak management, congestion relief, and system balancing as renewable penetration increases.
- Affordability: Lower system costs through reduced financing costs for distributed flexibility programs, deferred grid reinforcement and more efficient use of existing distribution assets.
- Business Value: Creation of repeatable, bankable portfolio models that attract private capital, support multi-year scaling of flexibility programs and enable service-based grid solutions to participate on a commercial basis.
Key deployment and scaling factors
- Define standardized performance and settlement rules so investors can assess and price portfolio risk consistently across diverse flexibility and distribution assets.
- Embed digital monitoring and automated control processes to reduce performance uncertainty and support dispatch confidence for DSOs and aggregators.
- Prioritize portfolios aligned with clearly defined system constraints, such as congestion relief or peak reduction, to ensure measurable grid value and regulatory support.
- Adopt multi-year, repeatable guarantee windows to provide pipeline visibility and enable financiers to develop scalable underwriting approaches.
- Ensure regulatory frameworks allow utilities and aggregators to participate directly, with flexibility outcomes eligible for cost recovery and predictable revenue treatment.
Case Study
InvestEU Programme, European Union (2025), Europe
The European Union’s InvestEU Programme deploys a €26.2 billion (approximately USD 30.7 billion) EU budget guarantee to de-risk investment across priority areas, including sustainable infrastructure and energy systems. Through portfolio-based guarantees that can function as first-loss instruments, InvestEU supports financing structures that absorb an initial share of losses across pools of projects rather than individual assets.
Under InvestEU, portfolio guarantees are implemented by partners such as the European Investment Fund, which structures first-loss risk-sharing facilities and deploys them through financial intermediaries rather than at the level of individual assets. This approach improves bankability for smaller, heterogeneous investments that have historically struggled to secure commercial financing on a standalone basis.
Within the Sustainable Infrastructure Window, InvestEU guarantees can be applied to aggregated investment programs that include distribution-level grid assets and flexibility-related investments. By covering a defined portion of early losses at the portfolio level, these guarantees enable DSOs and other eligible entities to bundle projects into investable portfolios with clearer risk allocation, lower capital costs and streamlined due diligence.
Member States can channel InvestEU guarantees through national implementing partners, supporting multi-year investment pipelines rather than isolated pilots and facilitating the scaling of flexibility and grid-support solutions aligned with EU energy and climate objectives.[2,3,4]
