Coal Asset Transition Tool
Open data supporting early coal power retirement in Southeast Asia
The transition away from coal power requires careful consideration of costs and benefits
The Coal Asset Transition tool, TZ-CAT, is an open data product that supports the refinancing and replacement of coal plants in an affordable, just way.
This tool estimates, plant-by-plant, the cost to ‘buy-out’ Power Purchase Agreements (PPAs), the cost of replacing coal with clean energy alternatives and highlights the potential savings from early retirement. It can be used for high-level screening to identify priority regions for coal phase-out, deep dives into a plant's financial metrics or operating costs, and for identifying the best candidates for early retirement.
TZ-CAT is currently available for the Philippines, Indonesia, and Malaysia.
TZ-CAT Malaysia, covering 25 coal units, presents a holistic picture of the current operational, financial, and environmental performance of Malaysia’s entire on-grid coal fleet, providing a critical foundation for designing viable transition strategies at the asset level.
TZ-CAT Philippines encompasses all 58 operational coal units in the Philippines, drawing from information collected from 209 power supply agreements (PSAs) which represent approximately 65% to 75% of coal generation.
TZ-CAT Indonesia brings together asset-level operational data on 118 assets — Indonesia’s entire coal fleet, and calculates the cost of buying out the remaining power purchase agreements (PPAs).
