Meghalaya — Verification Report (May 2026)

Page verified: /states/meghalaya · Retrieved: 2026-05-30. Tolerance: ±5% / ±2pp. (The HTML page returned HTTP 500; displayed values were read from the backing API api.energymap.in/api/states/meghalaya, which feeds the same tiles.)

What the page actually shows (demand fields, disambiguated)

The Meghalaya live-intelligence block exposes two distinct demand numbers — they are NOT the same thing and the first-pass report conflated them:

Field (API key)	Value	Timestamp	Nature
Current / live demand (demand_mw)	219.386 MW	"2026-05-29" 23:31 UTC	Modeled instantaneous snapshot (modeled_state_demand_v1), an off-season late-night reading — NOT a peak
"Peak" tile (peak_mw)	219.386 MW	"2026-05-29"	Mirrors the modeled snapshot — this is the IEA-1198 understatement: it surfaces the modeled instantaneous value, not a true 2-year/all-time peak
Official-summary peak (official_summary_peak_demand_mw)	361.000 MW	"2025-12-31" (period "Dec-2025")	CEA PSP monthly actual peak-demand-met for the state (cea_psp) — the page's only genuine recent-peak anchor

There is no dedicated all-time-peak tile in the Meghalaya payload (no record-peak field, no record date). The honest headline therefore compares the page's best actual-peak anchor — the official-summary 361 MW (Dec-2025) — against the authoritative CEA peak series, NOT the modeled 219 MW night snapshot.

Findings

• Peak demand (anchor 1) — reconciles on basis; the systemic tile bug is IEA-1198. The page's genuine recent-peak anchor is the official-summary 361 MW (Dec-2025, CEA PSP). Against the CEA FY2024-25 anticipated annual peak of 474 MW that is −23.8% — an expected forecast-vs-metered gap (the anticipated series is a planning forecast; actual metered December demand was lower). The CEA monthly anticipated peak for Dec is 459 MW, against which 361 MW is −21.4%. The first-pass headline of "219 MW vs 474 MW, −53.7% FAIL" was a misread: it compared the modeled off-season night-time snapshot (219.386 MW, 23:31) against an annual forecast peak — apples to oranges. The real defect is that the page's "peak" tile mirrors the modeled instantaneous value instead of a true 2-year/all-time peak; that is the known systemic understatement tracked by IEA-1198 (no new ticket). For reference, MeECL's own "unrestricted peak demand" is a derived figure (Connected Load × 0.85 × 0.6) of ~396 MW (FY2013-14 / FY2016-17), not a metered record — so no clean dated all-time metered record is published; the CEA series is the strongest authoritative comparator.

• Installed capacity (anchor 2) — BASIS difference, NOT a tolerance failure (IEA-1199). The page shows 395.110 MW, the sum of plants physically located in Meghalaya (3 plants — essentially the state-sector hydro fleet plus in-state RES). CEA's allocation-wise table reports the state's allocated share of 651.78 MW — a different accounting basis that adds Central-sector generation allocated to Meghalaya. CEA row (verified as Meghalaya's, after correcting the PDF's name-misalignment where the State/Private rows print above the state label):

  • State: Hydro 322.00 + RES 55.03 = 377.03
  • Private: RES 18.08 = 18.08
  • Central: Coal 51.60 + Gas 109.69 + Hydro 95.38 = 256.67
  • Sub-Total GrandTotal = 377.03 + 18.08 + 256.67 = 651.78 MW (arithmetic check passes), of which Thermal 161.29 (Coal 51.60 + Gas 109.69), Hydro 417.38, RES 73.11, RE-Total 490.49.

  Meghalaya is a hydro-heavy small NER state with allocated Central thermal it does not host, so allocated (651.78) > physical in-state (395.11). The −39.4% gap is the physical-vs-allocated basis issue (IEA-1199), explained, not a data error — do not score it a tolerance failure.

• Anchors 4–7 unverifiable on-page. AT&C losses, RPO compliance, residential tariff and real-time interchange are all null in the payload — there is no displayed value to verify against. The Meghalaya SLDC (meeclsldc.nic.in) and a metered all-time-record figure were not retrievable this pass; these anchors are honestly marked unverified rather than guessed.

Methodology

Live values read from the Meghalaya backing API on 2026-05-30 (the HTML page returned HTTP 500 on every attempt). Demand fields disambiguated directly from the payload keys (demand_mw/peak_mw = modeled instantaneous; official_summary_peak_demand_mw = CEA PSP monthly actual). CEA allocation-wise capacity from the Aug-2025 report (/tmp/cea_ic.txt); the Meghalaya row was re-confirmed against the PDF name-misalignment and reconciled arithmetically (State 377.03 + Private 18.08 + Central 256.67 = Sub-Total 651.78). CEA peak demand from the FY2024-25 Anticipated Energy Requirement & Peak Demand PDF (Meghalaya anticipated annual peak 474 MW; Dec 459 MW). No value interpolated or fabricated; unreachable sources and the absent all-time-peak tile are marked unverified.
