Tier
anchored · T2-annual-calibrated

No live feed. A published annual or monthly total from an operator, regulator, or satellite programme sets the level.

Published annual anchor (±20%)

Uncertainty
±20% of peak GW

Published envelope for this tier. See the uncertainty model.

Source provenance
verified · Verified upstream link

The snapshot value comes from a verified upstream feed or anchor.

MSLDC (Maharashtra State Load Despatch Centre) Monthly Curtailment Reports — MEASURED daily wind+solar curtailment with operator cause codes (mr10_MMYYYY.pdf). 33.28 GWh across 15 published months (2025-01 → 2026-06); ~26.8 GWh/yr annualised. Monthly publication, 1–2 month lag, months skipped — not a live feed, hence T2 not T1. Supersedes the prior Ember-rate estimate, which overstated by ~46x

Tier, provenance, and source are read at build time from src/lib/regions.ts — the same table the globe draws from. The validation record below is generated separately and gated against it by npm run ci:docs-drift.

Bad-conversions check

# Item Verdict Reason
1 DSM / deviation values used as curtailment no Ember curtailment rate applied to CEA generation; neither figure is a deviation/scheduling settlement
2 Capacity-at-risk MW used as curtailed energy MWh no CEA data is MU (= GWh, energy), not MW (capacity)
3 Instruction percentage without a generation denominator no Ember rate applied to actual combined generation TWh from CEA; denominator is explicit and official
4 Blank or dash treated as zero no Missing daily rows use withFallback to prior anchor; absent dates are not zeroed
5 Modelled fallback labelled as verified measurement partial sourceNote explicitly states: "Annual curtailed energy is derived from CEA official generation data (denominator) × Ember India 2024 state curtailment rate (modelled). Hourly shape is synthetic. Only the generation denominator is from a primary official source."

Discrepancy analysis

Pending: no backfill parquet yet for this region. Once HB.1 / HB.2 land the per-year totals for this region, this section will summarise the Δ vs TSO/Ember/IRENA and flag any year exceeding ±25%.

Known limitations

  • Curtailment rate (2%) is Ember's estimate; Maharashtra's mixed portfolio (Solapur solar + Satara/Dhule wind) has lower aggregate curtailment than pure-solar/wind states
  • Solar/wind split derived from CSV ratios; will update automatically as CEA data accumulates
  • Hourly shape remains synthetic (mixed solar + wind typical profiles)
