Field notes from inside India's grid.
The EnergyMap Research Team writes about the data, the pipelines, and the methodology behind India Energy Atlas. Every claim is traceable. Every source is cited. Every number is auditable.
How accurate are EnergyMap APIs?
A provenance spot-check of 384 IEX data points served by api.energymap.in against the iexindia.com market-snapshot page — plus why carbon-intensity numbers legitimately differ across public dashboards, and how our four methodology toggles let you pick the convention.
Rebuilding India's fuel mix from telemetry, not press releases
How we blend 15 SLDC state feeds with CEA generation tables to infer hourly coal, gas, nuclear, and renewable dispatch at the all-India level.
The SLDC coverage map: why half of India reports in near-real-time
Fifteen State Load Despatch Centres now publish demand, generation and frequency on a sub-hourly cadence. The other nineteen do not.
Calibrating the C&I bill calculator against a real JVVNL HT-5 invoice
A zero-error tariff walk-through — time-of-use blocks, wheeling charges, electricity duty and cross-subsidy surcharge, all matched to the rupee.
Mapping India's transmission grid, kV by kV
Notes on how we parse POSOCO, CTUIL and state transmission utility datasets into a single geometry layer — and where the seams still show.
The Atlas Journal is the research notebook of the India Energy Atlas team — a Section 8 non-profit publication of CIFR. Pieces are written collectively by the EnergyMap Research Team.
Every quantitative claim is traceable to a primary source — SLDC telemetry, CEA ledgers, IEX snapshots, CERC orders. Modeled values carry the label “modeled” where they appear.
