PEA tariff schedule (May 2023 onward, still current) filed under docs/finance/pea/; Ft 0.1623 THB/kWh for Sep-Dec 2026 from the PEA Ft page. The plant falls under Schedule 3.2.2 (Medium General Service, TOU, 22 kV). New section in sustainability.md: blended ~3.81 THB/kWh for two-shift production plus 132.93 THB/kW demand charge; electric steam ~4.7M-5.5M THB/yr at maturity against ~0.35M-0.8M of biomass fuel; self-consumed PV worth ~3.7 THB/kWh (~4.5-7 yr payback); solar thermal not recommended; the battery earns little from TOU arbitrage or peak shaving. biomass.md, scale.md, the utilities CSV note and the README follow.
