Zone 5
Transmission system limitations in Zone 5
A significant transmission system performance challenge in Zone 5 involves heavy energy market flows through the zone, resulting in potential high post-contingency line loadings.
Electricity usage
Peak electric demand typically occurs during the summer months. Large industrial loads in the Milwaukee metropolitan area are among the largest electricity users in the zone. In addition, there were multiple large load interconnection requests submitted that result in several T-D interconnection projects and network upgrades to reliably serve the load addition.
