Electric Transmission Lines and Substations, 60 Kilovolt and Greater, Minnesota

*** 7/19/22: This dataset and its accompanying map are no longer available since they are inaccurate and outdated. The Minnesota Department of Commerce is no longer maintaining or fielding requests related to this data as it has been unable to consistently obtain accurate, up-to-date information on high voltage transmission lines and substation locations from transmission owners in the state.***<br/><br/>For alternative sources for transmission line and substation information, see the transmission lines and substations section of MnGeo's information webpage on utilities: https://www.mngeo.state.mn.us/chouse/utilities.html#transmission<br/><br/>----------------------------------<br/>***Information describing the previously available dataset is provided in the rest of this metadata record for reference.***<br/>----------------------------------<br/><br/>The electric transmission network information consisted of transmission lines, with associated substations, designed to handle 60 Kilovolts or greater.<br/><br/>The Minnesota Electric Transmission Mapping Project developed two geographic information system datasets: transmission lines and substations. This metadata record describes both datasets.<br/><br/>In 2002, each electric utility company was mailed a request for their facility information which could be provided in either digital or paper form. The responses varied significantly in quality and quantity. In addition, the companies expressed concerns about providing the information because of security concerns. Data users were strongly encouraged to read the data quality section of this documentation.<br/><br/>Datasets were published in 2003, 2007, 2014, 2016, and 2021. In 2016 a few changes were made to improve the positional accuracy of lines and substations. The dataset was last updated in July 2021.<br/><br/>The Minnesota Electric Transmission Mapping Project was a collaborative effort between the Minnesota Department of Commerce and the Minnesota Geospatial Information Office.

Additional Info

Field Value
dsAccessConst Since this dataset is out-dated and cannot be maintained, the map is no longer available and the GIS data is not available to be requested.
dsCurrentRef The companies provided data from December 2001 to October 2003. The editing process corrected information until the winter of 2003/2004. In 2007, the positional accuracy of many transmission lines and substations was improved using several sources (see Lineage for details), and several new lines were added based on data provided by HDR. The 2007 dataset was NOT a comprehensive update for the entire state. The update from August 2016 included several new lines and substations that were filed with the Department of Commerce. The most recent update was in July 2021.
