⚡ Electricity — is there enough power for AI in Singapore?

Latest observations

Monthly observations

Question this table answers: what are the values and dates in each row of "Singapore — electricity generation, monthly total in GWh"? (source or retrieval date on each row)

Unit: gigawatt-hours (GWh) per calendar month, Singapore national total, as published (data.gov.sg column metadata: "Gigawatt Hours"), shown to the precision of the source (one decimal where the source publishes one; no rounding). "backfilled" = month retrieved retrospectively when the series was connected, kept apart from day-by-day observation. The source may revise earlier months; a revision overwrites the value on the next refetch and is recorded in the change ledger. Machine-readable: /sg/api/power_sg.json.

Why this chapter shows "observing", not a judgment

• This edition has no frozen criterion for judging Singapore's electricity conditions as good or bad. The Japan edition's power criterion (reserve-margin thresholds) applies to a different indicator published by a different institution, and we do not transplant thresholds across systems.
• The series is generation, not demand, not a reserve margin and not a price. Candidate indicators (EMA half-hourly demand, monthly peak demand) are listed as not connected or candidates until their re-use terms are confirmed and a definition is frozen.
• Until then: numbers, dates, and sources only. Do not infer thresholds we have not written down.
• What this chapter can say: how much electricity Singapore generated in each published month (national total, gigawatt-hours), as published by the Singapore Department of Statistics from Energy Market Authority data on data.gov.sg under the Open Data Licence; which month is the latest published and how many months behind today it is (the publication lag), and when each value was retrieved; which months were retrieved retrospectively when the series was connected, and when a published month was revised.
• What this chapter cannot say: what the demand, peak load or reserve margin is on any day or in any half-hour (the EMA half-hourly demand file is not connected pending written re-use terms); whether the grid is tight or has spare capacity, or what happened in months the source has not yet published (no criterion is frozen; nothing is estimated); the output of any plant or licensee, the fuel mix, or wholesale prices (plant-level data and EMC market data are outside this chapter).

Definition (v1.0 draft)

• Series: "Electricity Generation, Monthly" (Singapore Department of Statistics table M890831; source: Energy Market Authority), national total, gigawatt-hours per calendar month, retrieved through the data.gov.sg Datastore Search API (dataset d_ae4afbaf5bc96bde19d8ce85810ab9f4). Metric id sg.power.electricity_generation_monthly; machine vocabulary series_kind: measured_monthly.
• Values: as published, converted from the dataset's text fields to numbers; "na" is not recorded (missing, not zero). value_status is final because the source publishes no provisional flag; a revised month overwrites the previous value and the revision is recorded in the change ledger.
• Lag: the source publishes a month about five months after it ends (measured 2026-10-01: latest month 2026-05, 123 days after the end of that month; current value: about 5 months (measured 2026-10-03: latest published month 2026-05) ). The latest month is shown with its lag; the site's health page applies the threshold monthly_lag_long (184 days; health definition v1.3, decision D-2026-10-01-14) to this series, not the 62-day monthly threshold.
• Role in this edition: reference series. The annual water ledger is the main chapter of the Singapore edition (2026-10-02). The Beta rule still counts the daily retrieval of this feed together with the water feed.
• Backfill: months ending before the observation start are labeled retrieved retrospectively (retrieved_retrospectively: true, "backfilled" on the page) and are kept apart from month-by-month observation.
