Indah Water Konsortium (IWK) has adopted solar initiatives for renewable energy (RE) generation at its sewage treatment sites in Malaysia under the Self-Consumption (SelCo) model. This is in line with the National Energy Transition Roadmap (NETR) to reduce carbon emissions by 2040.
Under Phase 1, 396 of the IWK’s sewerage treatment plants (STP) have been identified as feasible and commercially viable for the installation of solar photovoltaics (PVs). Further, the company signed RM84 million worth of RE Power Purchase Agreements (PPAs) with four proponents. Upon implementation, IWK will be able to generate 22,781 MWh of solar energy annually, leading to total savings on electricity of RM1.9 million by 2026.
Meanwhile, for Phase 2 another 583 sites are undergoing a detailed evaluation, which will generate 21,500 MWh of solar energy annually, leading to total savings on electricity of RM1.8 million by 2027. IWK aims to reduce 34.4 ktCO2e of carbon emissions by 2027 with this initiative.
