Data and code for "Flexible grid access can accelerate clean-energy connections but redistributes curtailment risk"

This repository contains the data and reproducibility materials supporting the associated study of flexible grid access across five case studies in Great Britain, South Australia, the Netherlands and PJM. The archive contains harmonised and derived interval-level datasets, figure and table source data, metadata and provenance records, quality-assurance outputs, and Python code used for preprocessing, physical-access reconstruction, chronological market and emissions valuation, storage analysis, project-finance sensitivity, monetary normalization and generation of reported outputs. The five case studies comprise Hoprigshiels, B6/SCOTEX, South Australian Power Networks (SAPN), Zevenhuizen and PJM AH1-387. Evidence is classified as documented/observed, reconstructed, scenario or unavailable, consistent with the associated manuscript and Supplementary Information. Publicly redistributable derived data required to reproduce the reported results are included. Where underlying third-party source data are subject to redistribution or licensing constraints, the archive provides provenance information, source references, schemas, acquisition procedures and/or checksums rather than republishing restricted source files. The archive should be used together with the associated manuscript and Supplementary Information. Monetary, physical, emissions and finance outputs retain the evidentiary boundaries and case-specific assumptions described therein.
