"Towards a disaggregated electric power sector in the GTAP data base "
by Peters, Jeffrey C. and Thomas Hertel

From 1990 to 2010 electricity output increased 81% worldwide, and approximately 40% of the world’s total energy is consumed via the electric power sector. Coal and gas alone fueled over 40% and 20% of total world electricity production in 2009, respectively, and global trade of these input fuels has increased faster relative to many other tradable commodities. Technological advancements (e.g., horizontal drilling and hydraulic fracturing) may further expand fossil fuel energy reserves and export opportunities internationally. As a consequence of its prominent role in global fossil fuel combustion, the electricity sector is also responsible for approximately 33% of greenhouse gas emissions and as such has been the target of many carbon mitigation policies around the world. Electricity-related technologies and policies such as these beg the question of how regional electricity sectors and bilateral energy trade will evolve and, in turn, what effects these evolving trade patterns may have on the impacts and incidence of global energy and climate policies.

Computable general equilibrium (CGE) models are often used to provide global policy assessments. However, CGE models aiming to forecast electricity-related technology, policy, and their global implications require a consistent database with disaggregated electricity generating technologies as well as mechanism to address substitutability of generation technologies. Despite this, many CGE models and integrated assessment models treat the electricity sector as an aggregated sector due to a lack of a consistent database for generating technologies. This is exemplified by the GTAP database for CGE modeling which currently has just one sector (‘ely’) which encompasses “production, collection and distribution of electricity.” Because electricity from different technologies (e.g., fossil fuels, nuclear, hydro, renewables) are highly substitutable but vary greatly in produced emissions and other impacts, several users...
