Average MW by hour (per-day, Jan–Jul 2026) · batteries charge at midday solar surplus, discharge into the 08:00 & 20:00 peaks.
Average half-hour profile, Jan–Jul 2026 (MW). Weekends shed ~5–10% of demand.
Gross injection by facility type, GWh per month. CCGT/COGEN carries ~93–94% of the load year-round.
