Source — PREPA's operational generation feed (operated by Genera PR), the data behind genera-pr.com/data-generacion. A snapshot is captured about every 15 minutes and stored; charts read the most recent snapshot, and the history chart spans stored snapshots.
Generation mix — Percentage share by fuel (Bunker, Diesel, LNG, Coal, Renewable) as reported by the feed. By plant type sums the megawatts currently online for each technology (hydro, cogen, gas turbine, combined cycle, steam, renewable).
Available capacity — The feed's daily / weekly / monthly available-capacity series (MW), reflecting how much generating capacity was on hand over each window.
Reserves — Spinning reserve is synchronized capacity ready immediately; operating reserve is total reserve available. Both are supply-adequacy indicators — the cushion between what is generating and what could be called on.
Plant & unit dispatch — Real-time output per generating unit: MW (real power), MVar (reactive power; can be negative when a unit absorbs reactive power), and Cost ($/MWh) where reported.
