For the direct energy converter, even if it's attached to a fusion reactor, it still reports as generating 20GW of power. In the power graph with the 5s view, it reports generating 20GW every ~1.5/second when hooked up to a 2GJ fusion reactor. In the 10m view, it correctly reports the generated electricity. Ideally, it would be averaging the power production to 2GW instead of 20GW, which would correct all the views including 5s to +2GW of power, leading to an easier time telling which fusion reactors are running when and their actual power generation.
