Multi Sites Management
Lotus’s Phase 3
Rooftop Solar Project
Altervim, with its extensive experience in managing multi-site projects, oversees more than 60 locations and over 39 MWp of solar capacity simultaneously. One of our standout projects is Phase 3 of Lotus's Rooftop Solar Project. This phase encompasses over 61 stores across Thailand, each equipped with cutting-edge technology such as bi-facial PV modules, string inverters, and a digital monitoring platform. The project is capable of generating up to 50 million kWh of electricity annually, contributing to a reduction of over 750,000 tons of CO2 equivalent throughout its lifetime.

Floating Solar
CP Leadership Institue
Floating Solar Project
The Floating Solar Project at CP Leadership Institute showcases Altervim's expertise in floating solar technology by utilizing 8,800 sq. m of still water pond to generate clean energy. This floating solar installation, with a capacity of 843 kWp, can generate up to 1,160,000 kWh of electricity, which will help reduce carbon emissions by over 16,000 tons of CO2 equivalent throughout its lifetime. The project strongly supports CPLI's energy consumption needs and increases the percentage of renewable energy to up to 18% annually, contributing to CP Leadership Institute's sustainable development goal no. 7 of using affordable and clean energy.

Cell Site Solar
True Telecom Node B
Cell Site Solar Project
Altervim extended its capability and strong expertise in renewable energy to the telecom business by developing a clean energy solution for cell sites (Telecom Towers) for True. This project illustrates the uniqueness of our experience in renewable energy, covering more than 1,200 cell sites across Thailand with a total installed capacity of up to 5.98 MWp. It is equipped with various energy technologies, including on-ground mounting, telecom poles, and a digital monitoring platform. The annual generation of this project alone is over 7,600,000 kWh, avoiding CO2 emissions of up to 107,000 tons of CO2 equivalent throughout its lifetime.
