Table 3.

Comparison of the performance indicators of a ternary mix Wind-Nuclear-Gas with- and without cogeneration. Figures in black are input data for the MIXOPTIM software; figures in red are the result of the calculation.

Without cogeneration With cogeneration
Net average electric demand (net, ie excluding the electric power used to produce heat) (GWe) 40 40

Average heat demand (GWth) 60 60

Total average electric demand (total, ie including the electric power used to produce heat in the non-cogeneration case (GWe) 55 40

Hourly production cost of the electric power (M€/h) 3.0 2.50

Hourly CO2 production (kt/h) 29.5 19.4

Average imported electric power (GWe) 5.95 4.10

Average duration of a grid power outage (hours per year) 37 1.8

Average heat cogenerated (GWth) 0 30.6

Average heat produced by the complementary source to fulfill the heat demand (GWth) 45 29.4

Hourly production cost of the additional heat (M€/h) 3.41 2.23

Total production cost of power and heat (M€/h) 6.41 4.73
