North Central Wisconsin
Zone 1
Transmission system limitations in Zone 1
Zone 1 has a few key system performance issues. High voltages may occur in the northern portion of the zone under system intact as well as contingent system conditions. Potential overloads and low voltages that are a result of multiple contingency planning events will continue to be monitored. The most severe limitations are expected during both peak and off-peak periods.
Electricity usage
Peak electric demand typically occurs during the summer months, with some winter peaks appearing in the northern portion of the zone. Primary electricity users in Zone 1 include several large paper mills and food processing plants.
Electric load is forecasted to grow approximately 0.2 percent annually through 2033.
