A 200 MW transaction starts at the top of the hour and is terminated 30 minutes later. If a ten minute ramp is used, what is the integrated MWh for this transaction?

To determine the integrated MWh for this 200 MW transaction that starts at the top of the hour and lasts for 30 minutes, with a ten-minute ramp period, first, we need to understand what ramping means in this context. The ramp refers to the time taken to increase or decrease the generation output from one level to another, and during the ten minutes ramp period, the generation does not stay at a constant level.

Here’s how to break down the scenario:

1. Ramping up during the first 10 minutes: The transaction starts at 0 MW and ramps up to 200 MW over 10 minutes. The average output during this ramp-up phase can be calculated by taking the average of the start and end values:

• Average output = (0 MW + 200 MW) / 2 = 100 MW.

• The energy generated during this ramp-up period (in MWh) can be calculated by multiplying the average output by the duration in hours:

• Energy = Average output × Time = 100 MW × (10 min / 60 min) = 100 MW × (1/6) = 16.67 MWh.
