Every model begins with a snapshot of the current energy system, including all existing generation (power plants), storage (e.g. batteries), and transmission (major power lines) assets. For each asset, the following information is required:

Capacity (MW): The capacity of operating assets in the model’s start year, referred to as ‘Residual Capacity’ in the TZ-OSeMOSYS framework. Assets that are under construction or committed are included in the future system.
Location: Latitude and longitude coordinates.
Year of construction: The commissioning year of the asset.
Operational life: The expected number of years the asset remains in service.

Data sourcing standards for existing assets is detailed below.

Data sourcing standards – existing assets

Input variable	Model type	Gold Standard (‘Best in Class’)	Silver Standard (‘Good’)	Bronze Standard (‘Publishable’)
Power plant data - current (location, capacity, fuel, technology, start year, operational life)	CE & UD	Asset-by-asset validation and gap-filling by TransitionZero’s country analysts.	Asset-by-asset validation.	Global datasets.
Interconnector data - current (location, capacity, technology, start year, operational life)	CE & UD	Asset-by-asset validation and gap-filling by TransitionZero’s country analysts.	Global Transmission database with subnational or grid zone gap-filling.	Country-level copper plate from Global Transmission database, national or subnational level (grid-zone).
