A 360 MW Interchange Transaction is curtailed to 0 MWs at 1540. What is the hourly integration for the hour ending at 1600?

• A. 240 MWh
• B. 0 MWh
• C. 120 MWh
• D. 360 MWh

Answer: (A)

To determine the hourly integration for the hour ending at 1600, it's important to understand how the curtailment of the Interchange Transaction affects the total energy transferred over that hour. The transaction started at 360 MW, but it was curtailed to 0 MW at 1540.

From 1500 to 1540, the transaction operated at 360 MW for a duration of 40 minutes, which is two-thirds of an hour. To calculate the energy delivered during this period:

• For the 40 minutes (or two-thirds of an hour), the energy output can be calculated as follows:

[

360 \text{ MW} \times \frac{2}{3} \text{ hour} = 240 \text{ MWh}

]

From 1540 to 1600, the transaction is curtailed to 0 MW, meaning no energy is delivered during that time period.

Therefore, when calculating the total hourly integration for the hour ending at 1600, only the energy delivered before the curtailment (from 1500 to 1540) is relevant. Since the output was 240 MWh during that time and 0 MWh after the curtailment
