Mexico electricity price datasets and sources
Public CENACE-derived wholesale electricity price summaries, hourly profiles and node catalogue, with provenance, observation counts and machine-readable JSON.
Hour-of-day profiles
Published snapshot: 01 Jan 2018 — 31 Oct 2026. Updated: . MDA + MTR · MXN/MWh.
Mexico, 32 states, three electricity systems and catalogue control regions. Use the manifest to find the file for a geography and market. Availability is reported per file; observations may be incomplete.
Snapshot contents last changed: 04 Nov 2026. Last successful refresh check: 06 Nov 2026. Refresh metadata and underlying observation dates. Recent underlying observations are separate from the closed-month profile coverage shown above.
Mexico: latest published typical-day snapshot
Calendar month: 2026-10. National arithmetic mean PML at each operating-hour label. The two markets use their own observed populations, not matched-hour pairs. n = observed node-hours.

Data dictionary
These sums are arithmetic intermediates, not electricity costs or revenue; cost calculations require matching MWh quantities. Each profile file declares its columns. Each row is one month and operating hour, storing sums rather than rounded averages. To combine months, add the sums and divide by the total n. Restrict the calculation to whole months within your dates.
| Field | Meaning |
|---|---|
month | First date of the calendar month (YYYY-MM-01) |
hour | CENACE operating-hour label, 1–25; not a UTC timestamp |
n | Observed node-hours contributing to this row |
s_pml / s_ene / s_cng / s_per | Sums of PML, energy, congestion and losses. Divide by n for MXN/MWh. null means unavailable, not zero. |
published_at | Timestamp when this snapshot changed; not its price-coverage date |
Node catalogue
2,611 entries with ID, name, system, control region, state, municipality and load zone. This is a current mapping, not a historical membership series. No coordinates are inferred.

Last month’s price per node
One JSON file with, for every catalogue node and both markets, the arithmetic mean PML of the last complete calendar month and of the month before it, in whole MXN/MWh, with the observed node-hours behind each value. It is the number shown next to each node on the Nodes pages. Mean = sum of observed PML over the month’s node-hours divided by the number of node-hours; no demand weighting, no imputation. null means no observations, not zero. The latest month is the last one that every system has published to its final day for that market. Rebuilt with each site update.
| Field | Meaning |
|---|---|
months | For MDA and MTR: the latest complete month and the previous month (YYYY-MM) |
columns | Order of the eight values per node: mda, mda_hours, mda_previous, mda_previous_hours, mtr, mtr_hours, mtr_previous, mtr_previous_hours |
nodes | Node ID → the eight values; prices in whole MXN/MWh, hours = observed node-hours |
snapshot_at | When the file was built; not a price date |
Programmatic access
These versioned JSON files are available by HTTPS GET without an account. Read the manifest, fetch the selected file and cache it; use HTTP validators for refreshes. The interactive site also uses bounded public RPCs. There is no supported bulk-price API or guaranteed service level. Full hourly archives are not included in these public summary downloads.
