明尼苏达州的权力, Great River Energy advance joint 345-kV transmission line project with application for Certificate of Need, 路线许可
明尼苏达州的权力 and Great River Energy today are filing an application for a Certificate of Need and 路线许可 from the Minnesota Public Utilities Commission (MPUC) to build a high-voltage transmission line to bolster electric reliability in northern and central Minnesota.
The Northland Reliability Project is an approximately 180-mile, 双电路, 345千伏(kV)输电线路, 主要沿着现有的输电走廊, 从明尼苏达州北部到明尼苏达州中部. It will help maintain a reliable and resilient regional power grid as more renewable energy is brought online, 现有的燃煤电厂正在进行转型, 电气化继续扩大, 更频繁的极端天气事件发生了.
The jointly developed project is one of 18 transmission projects approved in July 2022 by the region’s grid operator, 中大陆独立系统运营商(MISO), in the first phase of its Long-Range Transmission Plan to integrate new generation resources and boost grid resilience as the energy transition continues. The Northland Reliability Project is the first project in this portfolio to reach this milestone of a 状态 regulatory process.
“The pace of change is upon us and we are laser focused on getting this line built to ensure reliability for our members and customers in northern and central Minnesota,” said Great River Energy’s Vice President and Chief Transmission Officer Priti Patel. “We are proud to be developing this project responsibly at every juncture. We have gone to great lengths to engage with community members and critical leaders over the last year, understanding that no voice is more important than that of a cooperative member who will be hosting this project on their property.”
The companies jointly held nearly 30 public open houses and numerous stakeholder meetings over the past year to provide opportunities for engagement with landowners, 地方政府, 机构, 和部落国家. 这些公众反馈反映在拟议的路线中.
“Collaboration with other utilities is critical as we invest in the transmission needed to maintain a reliable and resilient grid in northeast Minnesota and the Upper Midwest,” said 明尼苏达州的权力’s Vice President of Transmission and Distribution Dan Gunderson. “Transmission is an integral part of 明尼苏达州的权力’s EnergyForward strategy for serving customers and communities as we work toward achieving both our vision and Minnesota’s energy policy goal of a carbon-free future. As energy resources change, the regional power grid that delivers energy needs to change, too. This project will help retain our outstanding reliability, provide system support as resources transition to different operating profiles, 增加容量, 加强弹性, 提高电网的灵活性.”
须经监管机构批准, the companies expect construction to begin in 2027 and the line to be operational in 2030. 总费用估计在9.7亿至1亿美元之间.30亿年. MPUC将决定需求和最终路线, and separately review cost recovery for 明尼苏达州的权力’s share of the project. MISO allocation will help offset costs for customers and members.
Utilities across the region are significantly increasing the amount of renewable energy they provide to their customers. By reducing coal-based energy and more than doubling renewable energy, Great River Energy anticipates that by 2035 its retail electric sales will be provided by a 90% carbon-free power supply in alignment with the Minnesota carbon-free standard. 明尼苏达州的权力 was the first utility in the 状态 to deliver 50% renewable energy to customers in 2021 with plans to be more than 70% renewable by 2030.
The Northland Reliability Project is divided into two segments.
Segment one: Approximately 140 miles of new 345-kV 双电路 transmission lines will be constructed primarily near existing transmission line corridors, from 明尼苏达州的权力’s Iron Range Substation in Itasca County to Great River Energy’s Benton County Substation near St. 云.
Segment two: A 20-mile 230-kV line will be replaced with two 345-kV circuits along existing transmission corridors from the Benton County Substation to a new Big Oaks Substation that will be built as part of a separate project. A 20-mile 345-kV line will also be replaced along existing transmission corridors from the Benton County Substation to the Sherco Substation in Sherburne County.
其它改进:除传输线外, the Northland Reliability Project will expand the Iron Range Substation near Grand Rapids and the Benton County Substation near St. 云. A new Cuyuna Series Compensation Station will be built in Crow Wing County near the existing Riverton Substation.
