Renewable Curtailment
Historical curtailment — daily average by month
Renewable curtailment by technology (MWh/day)
Curtailment by hour of day
Hourly curtailment concentration
Annual curtailment by technology
Cumulative GWh by year
Generation by Technology
Monthly generation by technology
Aggregated real generation (GWh/month)
Thermal generation vs curtailment
Monthly bars + 12-month smoothed trend (recent months weigh more; data from 1 year ago counts half)
BESS Injection
Daily BESS injection
Daily dispatch (2023 – 2026)
BESS hourly profile by year
Daily average injection by hour
THERMAL GENERATION — HOURLY PROFILE BY TECHNOLOGY
Thermal 2023
Daily average by hour (MWh) — disaggregated by technology
Thermal 2024
Daily average by hour (MWh) — disaggregated by technology
Thermal 2025
Daily average by hour (MWh) — disaggregated by technology
ALL INJECTION — HOURLY PROFILE BY TECHNOLOGY (incl. BESS)
Injection 2023
Daily average by hour (MWh) — by technology; BESS charges stacked below axis
Injection 2024
Daily average by hour (MWh) — by technology; BESS charges stacked below axis
Injection 2025
Daily average by hour (MWh) — by technology; BESS charges stacked below axis
EMISSION DECOMPOSITION BY THERMAL TECHNOLOGY
Total thermal emissions by subtechnology
UGEN × EF — pie size proportional to total annual emissions
MADD EX-POST — SYSTEM EMISSIONS & BESS DISPLACEMENT
Monthly system emissions (OSE) + avoided (TGHGd) + induced (TGHGc)
Muted colors = observed emissions by thermal subtechnology · Green = displaced by BESS discharge · Red (below) = induced by BESS charge
AVOIDED EMISSIONS BY TECHNOLOGY — EX-POST (ALL BESS)
Displaced CO₂ by thermal technology
Merit-order displacement: most expensive thermal units displaced first (VC desc, EF desc)
