Backed by Leaders
and Built for Impact
With energy needs growing across the country, Filipino businesses require reliable and resilient power solutions now more than ever. Meeting this demand requires innovative partnerships with the private sector.
Advent Upgrade Solar, Inc. (AUSI) was formed to advance energy security, making clean, reliable power accessible to commercial and industrial enterprises.
Founded in 2023 as a 50/50 joint venture between Aboitiz Power Distributed Renewables, Inc.
