Amidst the global disruption and uncertainty caused by COVID-19, one very favorable development is that people now realize the fundamental importance of health and a clean environment.

In the energy sector, the mitigation of global change by among others shifting away from fossil fuels to cleaner forms of energy, especially renewables, and promoting energy efficiency have undoubtedly become even more urgent than ever before. For net energy importing countries like the Philippines, this has the added benefit of enhancing national energy security.

As chairman of Upgrade Energy Philippines, Inc. (UGEP), I therefore note with pride that the company is playing a role in this urgent national endeavor, particularly through the installation of solar systems in commercial establishments (e.g. malls, warehouses, etc.) and offering energy efficiency solutions to industrial establishments (e.g. waste heat recovery, etc.). These projects not only enable them to reduce their electricity bills, but also help to protect the environment and enhance national energy security.

UGEP has close to 30 MWs of commercial & industrial solar projects all over the country – from Pangasinan to Zamboanga – some of which have already been operating for a few years and others under construction or advanced development. Our strong and ambitious team are eager to grow this pipeline and contribute to a better future for all Filipinos by providing cost-effective solar energy solutions post COVID-19 era.
