Calculate the annual electrical energy output.

Step 1: Calculate the annual electrical energy output.
The power station capacity is $915 \text{ MW}$, and the load factor is $72.5\%$. There are $365 \text{ days/year}$ and $24 \text{ hours/day}$.

$$E_{out} = \text{Capacity} \times \text{Load Factor} \times \text{Operating Hours per Year}$$ $$E_{out} = 915 \text{ MW} \times 0.725 \times (365 \frac{\text{days}}{\text{year}} \times 24 \frac{\text{hours}}{\text{day}})$$ $$$$
