China's solar slowdown, seen from space: the Q2 2026 Solar Asset Mapper release
China's detected solar additions halved this quarter, whilst the Philippines posted the fastest growth among Asia's largest solar markets. TZ-SAM's latest data independently corroborates the slowdown reported on the ground.

Green steel, hour by hour: decarbonising India's steel
24/7 carbon-free electricity (CFE), green hydrogen, and shared renewable procurement together offer Indian steel a low-cost path to decarbonisation.

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
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
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

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

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
