Bangladesh

Provenance, tier, and validation record for bangladesh. No live curtailment figures on this page — those are on the globe.

Region id: bangladesh
Country: BGD
Waste modality: Solar
Coordinates: 24.00° N, 90.00° E

Estimated Data quality

Tier

estimated · T3-modelled

No live feed and no published total for this region. A typical-shape profile is scaled to a capacity-based or literature anchor.

Modelled profile, scaled to annual (±40%)

Uncertainty

±40% of peak GW

Published envelope for this tier. See the uncertainty model.

Source provenance

official-lead · Official source identified, live path not producing

An authoritative source exists and the loader is wired or scaffolded, but the live path is not producing usable data — geoblocked, auth-gated, or parser pending. The emitted snapshot falls back to modelled or last-good values.

Source

PGCB hourly solar generation (erp.powergrid.gov.bd). Waste unpublished — no national curtailment series. BPDB daily PDF is not the TSO path.

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.

Validation record

Last updated: 2026-08-20 · Sprint: S1 + HB integration · Paper section: Technical Validation §4.2

Source

Region id: bangladesh
Country: BGD
Tier: estimated
Kind: solar
Source: PGCB hourly solar generation (erp.powergrid.gov.bd). Waste unpublished — no national curtailment series. The previous 0.1 TWh/yr repo estimate was dropped.
Source URL: https://erp.powergrid.gov.bd/web/generations/view_generations_bn
Loader: bangladesh.json.ts
Structural gap: no
Waste status: unpublished. Missing ≠ zero. Live generation does not make waste T1a.

Calibration

Published anchors

TSO annual curtailment (latest published): none. PGCB publishes hourly generation by fuel, not curtailment, and no Bangladeshi operator publishes a national curtailment total or rate. BPDB 2024 RES curtailment is described as minimal (coal-dominant grid) but is not quantified.

IRENA annual: —

Discrepancy analysis

No backfill and no TSO anchor. Region relies solely on the live snapshot; nothing to triangulate against.

Known limitations

Waste is unpublished. PGCB publishes hourly solar generation, not curtailment, and Bangladesh has no published national curtailment rate. The 0.1 TWh/yr figure this region used to carry was the repo's own estimate and has been dropped. Do not read a zero waste profile as a measured finding.
The window is short. PGCB exposes roughly 48 hours of hourly rows. The 30-day generation total is annualised from the diurnal mean, not summed over two days.
TLS chain is broken upstream. erp.powergrid.gov.bd serves only its leaf certificate. The loader relaxes chain verification and checks CN/issuer explicitly.
