The daily merit order of Indian electricity, per state, from the Ministry of Power's MERIT portal — 2018 to the present.
Every row is one contract line: a station, the state buying from it, the variable charge that station declared to that state, the capacity allocated under the contract, and the energy actually scheduled. Ordered by the portal's own merit rank, so each state-day arrives as the published dispatch stack — the cheapest unit, the marginal unit, and everything between.
This is the number states dispatch on. The variable charge is what decides whether a state buys another MWh from a plant, from the exchange, or not at all. It is the closest public thing to a supply curve for the Indian grid, and it is not published as a time series anywhere else — the portal serves only the current day, and back-dated requests to its HTML page return errors.
What the charge is, precisely. Per CEA's MERIT submission spec it is declared at the state periphery, inclusive of interstate transmission losses. So the same station carries a different figure for each state it serves, and it is *not* that station's fuel cost. Treat it as a procurement price, not a production cost.
Coverage varies by day, not by state. Tamil Nadu published 44 plants in 2022 and nothing today; Uttar Pradesh disclosed through 2024 and then stopped. Disclosure has thinned over the window — 27 states publishing in 2018, 15 by 2025 — which makes the history the valuable part and is why it is shipped whole. Non-disclosing state-days are included with NULL costs rather than dropped, so the fleet, capacities and allocations stay visible.
2018-01-01 to present, daily, across the 34 states/UTs the MERIT portal carries. The portal typically serves D-2. Six small UTs (Meghalaya, Mizoram, Nagaland, Puducherry, Tripura, Uttarakhand) publish no merit order at all and are absent by source, not by omission. ~2.04M of 2.69M rows carry a declared cost.

- This is a declared dispatch charge, not a fuel cost. It sits at the state periphery inclusive of interstate losses, so one station carries a different figure per state. For the cost of burning coal at the plant, see the physical SRMC series on the API.
- The station name is not a key. A state can hold several contracts with one plant at different rates — Maharashtra bought from ADANI-TIRODA twice on one day, at Rs 2.38 and Rs 2.44. The key is (report_date, state, merit_rank). Grouping by station name silently merges contracts and loses a price.
- NULL cost is undeclared, not zero. A literal 0.00 is a must-run or must-take contract sitting outside the merit order (hydro, nuclear, RE, and some thermal). Including either as free coal pins a state's marginal cost at zero.
- Coverage varies by day. A null cost always means 'this state did not publish that day', never 'coal was free'. Check before comparing across states or across time.
- declared_capability_mw is unusable. The portal labels the column MWh and publishes MW, and it disagrees with allocated capacity on ~45% of rows. It ships verbatim for completeness; do not compute on it.
- Scheduled energy is the day's total for the contract line. There is no sub-daily resolution in this feed.
