Replication data and code for "Reference-output CfDs and missing-volume stop-losses: price–volume risk in France's proposed EPR2 support design"

This repository contains the replication materials for the article “Reference-output CfDs and missing-volume stop-losses: price–volume risk in France’s proposed EPR2 support design”. It includes derived annual and hourly statistics, data-extraction and analysis scripts, robustness grids, vector figures, formal-verification files and documentation supporting the results reported in the manuscript. The empirical material covers 87,672 non-missing French day-ahead hourly price observations for 2015–2024, including the repeated autumn daylight-saving hour. It also contains the historical stress-test calculations comparing the notified EPR2 missing-volume stop-loss with a counterfactual cap on total repayments. The underlying Montel/EPEX hourly workbook is licensed commercial data and is not redistributed. The archive provides the source-file SHA-256 fingerprint, worksheet and column conventions, a daylight-saving-aware extraction procedure and all derived non-confidential outputs needed for reproduction by an authorised user holding an independently licensed copy.
