Riga Technical University, LATVIA, Latvia We report on a life cycle assessment of the Latvian power industry in order to obtain an environmental profile of the Latvian power grid. The life cycle analysis covers both domestically produced and imported electricity, since Latvia imports about 40% of its electricity. Thus, in addition to covering large centralized and small decentralized power plants in Latvia, which has a relatively high share of renewable electricity (nearly 38% in 2006), the life cycle analysis includes power plants in Estonia, Lithuania, and Russia from which Latvia imports electricity. The background data are taken from the Ecoinvent database starting from the year 2006. The environmental effects were quantified using IMPACT 2002+ method. The results show that the total damage of electricity generation is 29 μPts/kWh and is originating from natural gas power (94%), biopower (3%), hydropower (2,6%) and wind power (0,4%). More in detail, the damage derives from resources (48%), climate change (39%), human health (11%), and ecosystem quality (2%). For the imported electricity, the total damage is 160 μPts/kWh; originating respectively from electricity SETAC Europe 19th Annual Meeting Abstracts - 127 imported from Estonia (55%), Lithuania (22%) and Russia (23%). These damages derive from resources (46%), climate change: (27%), human health (25%), and ecosystem quality (2%). Aggregating the generation and import according to their shares in the mix yields a total damage of 75 μPts/kWh, which represents the ecological profile of Latvian power production. The import of electricity increases the total ecological effect by 160 % from 29 μPts/kWh to 75 μPts/kWh. The largest share (40%) of the contribution to the environmental impact due to imported electricity can be traced to oil shale condensing power plants in Estonia.
