Maharashtra Hourly

Source status

not-yet-secured

No stable public Maharashtra hourly load API is secured yet. The strongest public fallback today is NPP all-India realtime MERIT JSON, not a Maharashtra-specific hourly feed.

NPP MERIT realtime demand

usable-national-only

Public JSON endpoint with optional date parameter; returns all-India demand-met timeseries.

NPP MERIT fuel-wise generation

usable-national-only

Public JSON endpoint with optional date parameter; returns fuel-wise generation timeseries.

MAHASLDC main site

blocked

Returned HTTP 500 during both direct HTTP checks and a real-browser probe on March 16, 2026.

MAHASLDC DSM landing

public-landing-only

Public landing page is reachable, but it only exposes application links. No clean realtime demand JSON or CSV endpoint was exposed in page source or browser network logs.

MAHASLDC DR2 WebAccess

maintenance

The public page reported server maintenance during checks on March 16, 2026.

MAHASLDC Big Data Analytics

timeout

The public analytics host timed out during direct checks on March 16, 2026.

Next Collection Work

Inspect MAHASLDC authenticated portals for exportable load-curve tables or chart XHRs.

Check whether Maharashtra publishes demand snapshots through a public SLDC dashboard separate from the DSM landing.

Keep NPP all-India MERIT as the fallback national hourly source until a Maharashtra-specific collector is secured.
