First repurpose target with real legs. DE day-ahead battery arbitrage (free Energy-Charts,
2019-2025, 2464 days). 4h/1MW/85pct: perfect-foresight e93k/yr/MW (>> e50-80k viability),
naive only e10k -> forecasting/RL gap = 89pct of value. Per-year GROWING (e28k 2019 ->
e141k 2025) = not competed away (batteries slow to build = operational moat). Structurally
opposite of trading: real economic value (not zero-sum), growing (not arbitraged), and 89pct
of value is forecasting/RL = exactly the engine's job. Caveats: perfect-foresight is upper
bound (realistic ~60-85pct capture -> ~e55-80k/yr/MW); needs a battery (capital) or sell the
dispatch software to operators (engine-as-product) or aggregator. NEXT: forecaster + RL
dispatch, measure realized-capture vs foresight.
