India grid carbon-intensity dataset for dynamic building LCA

Annual CO2 emission factor of India's national electricity grid, FY2014-15 to FY2025-26, harmonised from four editions (v10.0, v12.0, v14.0, v22.0) of the Central Electricity Authority (CEA) CO2 Baseline Database. The reconstruction reproduces every factor published in v22.0 within 0.0001 tCO2/MWh. Over FY2014-15 to FY2025-26 the factor fell from 0.779 to 0.678 tCO2/MWh (-13.0%). The dataset provides three scenario projections to 2070 (business as usual, net zero by 2070, policy-accelerated), held constant to 2100, an annual uncertainty band, and lifetime-average factors for buildings commissioned from FY2027-28 to FY2040-41 with service lives of 30, 50 and 60 years. Every factor is given per MWh generated and per MWh delivered after transmission and distribution losses. Validation, robustness and sensitivity results are included. The package contains CSV data files with a data dictionary, SHA-256 checksums of the CEA input files, Python code that rebuilds every data file from those inputs, and an Excel calculator that compares static and dynamic operational CO2 for building life cycle assessment.
