The Philippines is aggressively working towards a clean energy scenario (CES) target of 50% share of renewables in the power generation mix by 2040. The project will focus on understanding how the CES will displace fossil-based plants, and analyze the impact on energy supply, tariffs, and grid reliability through strategic integrated power generation and transmission planning. It will build capabilities in simulating medium- and long-term power and transmission scenarios using modeling software where results will be used for policy making, target setting, and investment promotions. It fosters an integrated planning approach by aligning long-term power generation development plans with transmission planning.
