BMRS Dataset

This repository contains the data and methods used to build and analyse a half-hourly Great Britain balancing-market dataset derived from the Elexon BMRS portal.
The workflow begins with programmatic extraction of demand, renewable forecasts and actuals, generation by type, margin, imbalance, NETBSAD, system prices, and frequency data from BMRS, which are then consolidated into a structured source panel.
This panel is transformed through the UK Grid Analysis workbook layer, where the BMRS_Base query engineers the main analytical variables, including renewable generation, renewable share, gas share, forecast errors, imbalance and price measures, frequency deviations, bins, and lag/delta terms.
The resulting export tables feed Python-based econometric analysis covering descriptives, correlations, OLS, robust and HAC inference, diagnostics, fixed effects, quantile models, event models, influence tests, and related robustness checks. In a second analytical branch, daily UK and EU gas market data are merged into the BMRS panel to create patched datasets used for gas-control specifications and extended testing. Final curated manuscript figures are then generated from the statistical result workbooks. The package is intended to support transparency, reproducibility, and reuse of the study’s data construction and empirical workflow.
