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
WPS reviews budgets, analyzes sales and construction forecasts and develops the rate case.
WPS files rate case at the Public Service Commission of Wisconsin (The Commission).
The Commission audits budget information from WPS, asks WPS 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.
