Description

Electricity transmission projects are vital for integrating renewable energy and accelerating decarbonization, yet they are often excluded from climate finance. This work uses scenario-based energy system models (the open-source OSeMOSYS Global model) to pre-screen the applicability of the Climate Finance Principles for Green Grids and Interconnectors and assess transmission investments in the ASEAN region. This work identifies eligible projects based on two mitigation indicators, emissions reductions and increased uptake of low-carbon electricity. The approach demonstrates how long-term energy modelling can guide more objective and consistent classification of grid projects for climate finance, unlocking critical investment for green grids in Emerging Markets and Developing Economies.
