What it means for a refund claim in Wisconsin
- Disputes over overbilling go to the Public Service Commission.
- Read the utility's tariff rules on billing and meter error too: tariffs often repeat or extend the commission rule.
- Municipal utilities and cooperatives usually set their own billing rules.
Discovery Energy reviews 36 to 48 months of history on every account and pursues the longest period each jurisdiction allows. See how overcharge recovery works, or compare Wisconsin with every other state.
