The sentence describes an action in progress in the past that was interrupted by another past action (the lights went out). For this we use the Past Continuous construction: was/were + verb-ing. So the correct variant is «was doing». «has done» is Present Perfect, «does» is Present Simple, and «is doing» is Present Continuous, so they do not fit a past situation.
