There are lots of upwell structures littering space with a “Low Power” warning. Yet despite the fact they have no power they still provide services that have a “magical” supply of free power.
Option 1 - All structures have the services, repair, corporate offices, insurance preinstalled - with an option to turn them on or off (without fulling penalty). When online they require 1 fuel per hour.
Option 2 - These services stop operating when the station is not fueled.
Low power doesn’t mean no power. However, to end the junkyard of stations make them “abandoned” after 30 days of no fuel. The structure becomes hull only and doesn’t invoke concord response in High Sec.
