Grid Energy Mix
The Grid Energy Mix is a breakdown of the different sources of electricity production in a given grid. In the left column of the tab, eleven different types of electricity production are listed. The second column specifies the CO2 emission per kWh associated with each of these sources. By default, the values given here come from an IPCC publication1 and represent the 50th percentile of a meta-study performed on 296 publications. You can also choose to supply custom values from the drop-down box on the top of the column. In this case you should have a good source giving reliable values for the grid you are considering. The third column specifies the fractions of the different production types for the grid. Default values exist for several European countries and are taken from a study conducted at the Paul Scherrer Institut (PSI) in Switzerland2. If you do not find the country of your installation in the list, or if you have more reliable values, you can choose the 'Custom' option and supply these values yourself.
The resulting LCE Grid value is computed automatically as the selections are performed and displayed on the right side of the tab.
