Textile plant, Vietnam, industrial rooftop solar
Problem
surplus rooftop generation and commercial exposure under the site's rooftop solar offtake agreement.
Work
- matched solar output to factory consumption, assessed minimum consumption and surplus energy treatment, compared time of use, solar capture, power factor and prospective capacity charge value streams across several all in one cabinet configurations, and modelled fifteen year returns and sensitivities.
not the best configuration
The largest configuration was not the best configuration. Contract structure and surplus recovery outweighed arbitrage.
Consequence
the recommendation was a phased approach with a defined trigger, since validated by the 2026 change to the surplus sale cap described on the Vietnam page.
