Hourly bands (ONEE MT, typical): pointe 17h–22h (winter) / 18h–23h (summer); pleines 07h–17h/18h; creuses 22h/23h–07h. Cos φ: target ≥ 0.93 (some contracts 0.9) — below, a reactive-energy surcharge applies; above, batteries de condensateurs typically pay back < 18 months. Puissance: RDPS penalty when max demand exceeds the souscrite; oversubscription wastes prime fixe. Use the exact tariffs of YOUR contract — defaults are indicative only.
