Difference between Offer capacity of 100MW and 100000 MWH energy output

Question

I got a energy generation question.

if a plant has an Energy output of 100,000MWh what does it mean if it has an Offer Capacity of 100MW?

seeing it in a case study and was confused.

I am not sure what offer capacity is when i know that 100,000MWH is the output and something like a powerplant of 100MW would produce 100MWh not 100,000MWh

Answer 1

For capacity, 100MW is the max load of the plant at any given time.

The energy output is referring to the amount of MWh over a certain time frame. E.g. if you could run a 100 MW plant 24/7 for a year it will have 100 x 8760= 876000MWh of output over a year.

They may be using a different time frame in order to get 100,000MWh output with a 100MW plant.

Also, a plant likely isn’t going to be producing 100% output 24/7 due to planned and forced outages and operating below max load and such so that will reduce the total MWh output too.
