SWITCH-China: Modeling the Transition of the World’s Largest Power Sector

Gang He

November 13, 2023

China’s power sector

~ 1/4 of global coal consumption
~ 40% of global solar/wind capacity
~ 1/8 of global carbon emission
A sector under fast transition
Its future with high uncertainties

Challenges

High spatial temporal resolution model
Data
- Availability
- Accessiblity
- Credability
Transparency
Comparison

SWITCH-China

SWITCH-China model structure

Data

Generation
- Technology: solar, wind, hydro, nuclear, coal, gas
- Wind/solar resources profiles
Transmission: planned the uhv lines
Demand: future demand projections
Load: provincial typical load profiles

Costs
- Capital costs
- Fuel costs
- Carbon costs
- Transmission costs
Policy
- Development targets
- Carbon neutrality goals
- Environmental targets

China modules

Adapt to China’s energy policies and priorities

Plans: Technological goals and limits
- Wind/Solar/Offshore wind plans
- Coal limits
Energy water nexus / Multiple sectors
- Electricity-Carbon-Water
Emerging technologies
- Storage
- Pumped hydro
- Offshore wind
- Hydrogen

Low cost of renewables

Water implications

Where to place storage

What SWITCH-China can do?

Power transition technology pathways
- Capcity mix
- Generation mix
- Impact of costs and technologies
- Impact to carbon emission and pollution
- Impact of policy and regulations

What SWITCH-China can do with other models?

Transport model, e.g. Li et al. (2022)
Building model
Air quality/human health model, e.g. Luo, Garcia-Menendez, Yang, et al. (2023), Luo, Garcia-Menendez, Lin, et al. (2023)
Input output model
Social economic model
