Data, uncertainties and limitations
The data for the model come from a variety of sources, the main of which are:
|Electricity production and primary inputs||IEA Statistics and Data|
|Capacity of different plant types per region||Energy Statistics and Data (Enerdata Global Energy & CO2 Data; IEA Statistics and Data), IRENA REsource database (2016)|
|Performance of fossil fuel and bio-energy fired plants||Hendriks et al. (2004a), various sources described in De Boer and Van Vuuren (De Boer and Van Vuuren, 2017)|
|CCS plants and storage||Hendriks et al. (2004b)|
|Prices||IEA Statistics and Data|
|Hydropower potential||World Energy Council (WEC, 2010)|
|Solar and wind costs||Various sources described in De Boer and Van Vuuren (De Boer and Van Vuuren, 2017)|
|Nuclear power - technology and resources||WEC-Uranium (WEC, 2010; MIT, 2003)|
|Hydrogen technologies||Van Ruijven et al., 2007|
The two main uncertainties are calculation of future energy conversion relating to development rates of the conversion technologies, and the consequences for the electricity system of a high level of market penetration of renewable energy. TIMER electric power generation submodule has been tested for different levels of market penetration of renewable energy (De Boer and Van Vuuren, 2017; Pietzcker et al., 2017; Luderer et al., 2017). The model was shown to reproduce the behaviour of more detailed models that describe electricity system developments.
The model describes long-term trends in the energy system, which implies that the focus is on aggregated factors that may determine future energy demand and supply. However in energy conversion, many short-term dynamics can be critical for the system, such as system reliability and ability to respond to demand fluctuations. These processes can only be represented in an aggregated global model in terms of meta-formulations, which implies that some of the integration issues regarding renewable energy are still not addressed. A more detailed discussion on the model limitations can be found in De Boer and Van Vuuren (De Boer and Van Vuuren, 2017).
Another limitation is the formulation of primary fossil-fuel conversions in secondary fuels. TIMER currently does not include a module that explicitly describes these processes.
