Maharashtra Hourly
Measured from the MSLDC DSM report since 24 Sept 2026, latest 2 Oct 2026. Its daily energy is within 0.6% of POSOCO's energy met. 94% of the last 7 days' hours arrived.
Frontend Access
IEIO remains the live collector and scheduler. Atlas imports those tables and serves a stable read layer for the app.
The frontend should query Atlas endpoints for product pages and only use IEIO domain routes directly during collector validation.
