The rate case process takes time — about 18 months from developing the case to the time new energy rates take effect.
Rate case process
- Rate case preparation
MGU reviews budgets, analyzes sales and construction forecasts and develops the rate case.
MGU files a rate case with the Michigan Public Service Commission (The Commission).
The Commission and interveners examine budget information from MGU, asks us to defend and update figures provided.
The public has an opportunity to comment. Witnesses that support the figures in the rate case are available for cross examination in a court-like proceeding.
The Commission decides any outstanding matters and issues a written order on the rate request.
- Rates take effect
New rates take effect for customers.
