8 Electricity and Heat Gross Electricity - the sum of the electrical energy produced by all of the generating sets (including pumped storage) measured at the output terminals of the main generators. Gross Heat - is the heat produced by the installation, including the heat used by the installation s auxiliaries which use a hot fluid (for activities such as space heating) and losses in the installation/network heat exchanges, as well as heat from chemical processes used as a primary energy form.

16 Electricity and Heat Net Electricity the gross electricity production less the electrical energy absorbed by the generating auxiliaries and the losses in the main generator transformers. Net Heat Is the heat supplied to the distribution system as determined from measurements of the outgoing and return flows Plant Boundary Gross Electricity Net Gross Heat

17 Electricity and Heat Gross Electricity - the sum of the electrical energy produced by all of the generating sets (including pumped storage) measured at the output terminals of the main generators. Gross Heat - is the heat produced by the installation, including the heat used by the installation s auxiliaries which use a hot fluid (for activities such as space heating) and losses in the installation/network heat exchanges, as well as heat from chemical processes used as a primary energy form. Gross production - Own? Use = Net production Net Electricity the gross electricity production less the electrical energy absorbed by the generating auxiliaries and the losses in the main generator transformers. Net Heat Is the heat supplied to the distribution system as determined from measurements of the outgoing and return flows
