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 |
