User, 17 Oct 2026: "only put solar on the factory, prepare the other
buildings for solar, option a and b should operate on biomass".
- Steam: two 500 kg/h biomass modules (Getabec class, 6M to 10M THB) plus
a fuel store and handling block (1M to 2M, estimate) in both plans; the
electric bank becomes the alternative. ~0.67M THB of fuel a year against
~4.9M for electric steam; grid demand ~264 kW instead of ~980 kW.
- Solar: ~520 kWp on the factory roof (the biomass-case optimum is ~500 to
550 kWp, hourly sketch in sustainability.md "PV size with biomass
steam"); office roof and parking canopies built PV-ready (~120 kWp
later). ~87 % used on site, ~61 % of the plant's electricity.
- Calculator: biomass default, bFuel row, pvKWp 520, pvSelf 87, iso fills
the factory roof first and shows the other roofs as PV-ready.
- Numbers: launch plant ~168M / 232M / 296M with contingency; Plan A
~182M (~2M above 180M: the Chinese-route lever priced only electric
boilers; a Chinese biomass quote is the way back), Plan B ~217M (label
~215M), ~35M more. Calculator EBITDA A 2.17M, B 2.23M USD.
- CSV, total-investment, revenue-model, sustainability, scale, biomass,
site-candidates, boi, steam-cooling, construction RFQ (canopies
PV-ready), README, roadmap; business plan draft 0.3 rebuilt (A and B
63 pages) with new renders.
- Cover and section 6.2 now use the isometric plant view of the plant and
business plan calculator, drawn with each version's own preset: the
cover (roofs, no labels), Figure 8 the site from above, Figure 9 the
ground floor cut open, Figure 10 the press hall close up. The FreeCAD
aerial render, the Mueang Chi site plan and the hall layout sketch are
no longer in the plan; the captions say the calculator draws the Payap
scenario model while the 6.2 text and zone table are the Mueang Chi
hall.
- New section 5.5 "The software: plant overview, factory console and
artist platform" with six screenshots of the demos: the plant overview
(simulated SCADA), the factory console press floor and its ERPNext
link, the artist ordering offer, fan funding and the record passport.
Simulated data is marked as such; the platform name stays undecided.
- Figures renumbered (budget card 11, cash 12) and named in the
section 15 source table. Renders in docs/renders/calculator/ and
docs/renders/demos/; README bullet updated.
