Nusa Tenggara’s first solar gigawatt displaces Java’s coal, not local diesel
In our model, Nusa Tenggara's diesel fleet already sits idle by 2034. The first gigawatt of solar therefore displaces Java's subcritical coal instead, cutting 1.78 MtCO₂ a year at a net system cost of US$28.4 million (IDR 511 billion), around US$16 per tCO2 avoided
