aFRR
aFRR, or automatic Frequency Restoration Reserve, is a balancing service activated automatically to restore system frequency. aFRR describes a market or contractual element that can shape the revenue stack of an energy storage project.
What this means in practice
In practice, aFRR is reflected in the assumptions, contracts, operating strategy or financial model of the project. It helps define how the asset works, how risk is allocated and how value is converted into measurable cash flows.
Why this matters
aFRR matters because it affects project value, risk allocation, financing capacity and the credibility of the investment case. For investors and financing institutions it is one of the elements that determines whether the model is realistic and defensible.
How Envalis views it
At Envalis, aFRR is assessed as part of an integrated view of the project. We connect technical assumptions, market logic, contract structure and financial outputs to show how this element affects value, risk and bankability.
Application in projects
aFRR is used in project valuation, bankability assessment, scenario analysis, stress testing and the preparation of materials for investment or financing decisions.
