Analysis
Philippine solar could close the renewable share gap in 2030
Modelling shows the 35% renewable energy target drives 3 GW of additional solar capacity, while underperforming coal units taken offline increases reliance on firm capacity and adds 1 GW of geothermal

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

Analysis
Philippines coal obligations limit renewables despite fuel price shock
High fuel prices displace 37 TWh of Philippine fossil generation, but offtake rules keep 3 TWh of coal running, crowding out renewables and limiting system flexibility
Analysis
Philippine fuel shock scenario shifts investments to renewables but fossil lock-in remains
Under persistent fuel shocks, the Philippines could incur US$90.5bn in fossil system costs, with storage costs at just over 10% of this total, pointing to a cost-efficient path to reduce fuel dependence
Analysis
How a Java-Sumatra interconnection could accelerate Indonesia’s decarbonisation
Scenario Builder modelling shows the inter-island transmission link could raise Indonesia’s renewable generation share to 48% by 2040
Analysis
Heavily contracted coal strains Philippines grid as outages surge in 2025
TZ-CAT data shows several heavily contracted units already exceed outage thresholds by 189%, posing risks to grid stability and electricity prices
Analysis
Batteries are Pakistan’s antidote to volatile fossil fuel prices
Investing US$500m in batteries plus renewables could save up to US$2.87bn in RLNG operating costs by 2030.
Analysis
A Japan powered by 90% clean energy is achievable only with a flexible system
New analysis shows how interconnectors, flexible nuclear and long-duration storage could help reduce wasted renewable energy in Japan’s power system.
