  1. ^ Based on the data from Kannan, R. Uncertainties in key low carbon power generation technologies–implication for UK decarbonisation targets.
  2. ^ The CO2 reduction rate of CCS technology, ranging from 70-90%
  3. ^ The average investment cost of PC is 674$/kW, equals to about 4596 CNY/kW; The CCS incremental cost is about 66% and energy penalty is about 27%. Data mainly based on: Wu, N., Parsons, J.E., Polenske, K.R.. The impact of future carbon prices on CCS investment for power generation in China.
  4. ^ The average investment cost of IGCC is 1490 $/kW, CCS incremental cost is about 34% and CCS energy penalty is about 17%. Wu, N., Parsons, J.E., Polenske, K.R.. The impact of future carbon prices on CCS investment for power generation in China.
  5. ^ The average investment cost of biomass is almost the same with that of the coal-fired power plants with the same capacity.

[edit] Existing capacity

Table 1. Capacity portfolio by technology in 2010 [1][2].

Conventional coal (<=300) Super critical (SC) Ultra super critical (USC) Combined Cycle gas turbine (CCGT) Biomass Nuclear Hydro Wind Solar

  1. ^ The capcaity data of coal power are mainly adapted based on the data in: Technology roadmap: High-e�ciency, low-emissions coal-�red power generation, Tech. rep., International Energy Agency 536 (2012).
  2. ^ The data other than coal power capcaity are mainly based on Global data and power etrack: country view of China (2014). URL http://www.poweretrack.com/CountryOverView.aspx?538&countryid=345&countryName=China, last accessed on 20/5/2014. The author has simplified the data, such as the oil-fired power plants is 7.16 GW, while we assume it as zero as China has no clear intention to expand the oil use in power supply and the capacity of oil-fired capacity has declined since 2000.

[edit] Power demand

The electricity demand in China was 4192.3 TWh in 2010 with an increase of 14.8% relative to 2009, and the yearly peak load was 588.23 GW with an increase of 15.75% [1].
