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.
Analysis
How we modelled 24/7 CFE and green hydrogen for India’s steel sector
Using our Indian power sector model to understand system effects, landed costs for steelmakers, and the assumptions behind them.
Analysis
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

Scenario Builder, redesigned: faster, more auditable and built to grow
Filter hundreds of thousands of input rows and chart multiple scenarios side by side - on the same modelling engine you already trust.
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
Update
Seeing the ASEAN Power Grid as one connected system
As ASEAN prepares for cross-border power trade and new transmission projects, Scenario Builder's ASEAN Power Grid model brings regional power-system analysis into one open access environment.
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
Update
Spain's solar surge and the case for energy resilience: the Q1 2026 Solar Asset Mapper release
As fossil fuel markets reel from the Iran crisis, TZ-SAM's latest data shows how countries investing in solar are reaping the rewards. Spain is leading the way in Europe.
