Conclusion:
Maxx Saver and Power Maxx target different usage profiles. If you choose 4Change Energy, it is critical to select the plan that matches your historical data. The primary risk with bill credit plans is that customers are often overly optimistic about controlling their usage. Missing the required consumption thresholds means losing the bill credits, which can cost hundreds of dollars annually.
