It doesn't generate any power whatsoever, and doesn't fire at all. Conversely, one with a single basic reactor (enough to cover static energy as design requires) and enough collectors to power combat operation does indeed operate at full capacity...
Here is station with energy collectors firing torpedoes (those little yellow dots to the right of it), it is firing continuously. Each torpedo shot requires 28 energy- from the screenshot alone, you can tell it must have recharged energy after firing at least 3 shots (84 energy out of 90 max, but station has much more than 6 energy)
Did the test again just for images
