WHY NOW
01
COST
Industrial grid tariffs in Vietnam rose 21% between 2023 and 2026, with further increases expected. Electricity is already the 2nd or 3rd largest operating cost for most mid-size factories.
02
EXPORT
EU and US brands increasingly require suppliers to report and cut Scope 2 emissions — CBAM and brand RE100 targets.
03
CAPEX
Most factories don't want to fund — or run — a power plant outside what they do best.
