This is an illustrative projection, not a prediction, meant to make a complex topic personal. It compounds your current bills using two annual-increase assumptions drawn from the research: a higher-demand path (+7%/yr electric, +6%/yr water) and a managed-growth path (+3%/yr electric, +2.5%/yr water).
The ranges reflect published analysis: estimates that a gigawatt-scale data center could raise residential electricity rates without protections; DTE's data-center pipeline of up to 8.4 GW; and recent water-rate increases. Energy demand is only one factor among many, and well-designed policy and protections can change the outcome — which is exactly why the public conversation matters.
