- Retiring the plant
- Converting it from coal to natural gas
- Adding a new natural gas combined-cycle plant (coincident with retirement)
- Adding new air quality controls

The decision must make economic sense for customers and ensure a robust and reliable power supply for the Upper Peninsula of Michigan.
