GTAP-Power Data Base: Version 11

Abstract

This paper provides an overview of the version 11 of the Global Trade Analysis Project (GTAP) Power Data Base, which covers 141 individual countries, 19 composite regions and 76 sectors, reporting data for five reference years – 2004, 2007, 2011, 2014 and 2017. The newly constructed database builds on the previous efforts, introducing several new features and updates. First, by extending the coverage across reference years, GTAP-Power 11 Data Base uses updated levelized costs of electricity generation estimates. Second, the database updates the shares of transmission and distribution costs across countries. Finally, the newly constructed database includes complementary accounts of greenhouse gases and air pollutants. In an application of the database, changes in greenhouse gas emissions from electricity generation in each country are decomposed into changes in (1) the amount of electricity generated, (2) the mix of technologies, and (3) the emissions intensity of each technology.
