To further increase the Group's renewable energy generation capability, WHA Utilities and Power (WHAUP) is currently conducting feasibility studies to install solar rooftop panels coupled with battery energy storage system (BESS) at the wastewater treatment plant at Eastern Seaboard Industrial Estate (ESIE). The installed solar rooftop panels will generate approximately 820 MWh of solar power with 550 MWh of BESS capacity.
This project will help WHAUP substitute 1,176 MWh of electricity off-take from the grid, which is equivalent to saving on electricity expenses of 4.12 million Baht per year. In parallel, WHA Group will be able to reduce greenhouse gas (GHG) scope 2 emissions by 588 tCO2e due to grid electricity substitution. The solar rooftop panels are expected to construct in early 2021 and commence during the later months of that same year.
