This feature class represents known electric power substations within the continental US and Puerto Rico that are located within 20 miles of the coastline. Substations are facilities and equipment that switch, transform, or regulate electric voltage. This data set includes taps, a location where power on a transmission line is tapped by another transmission line. Many large rivers and bays hydrologically related to coastal waters were considered part of the coastline to make this data set as detailed and complete as possible. Therefore, applicable substations as far inland as Washington D.C., for example, are included. This data set is currently incomplete; data for Alaska, Hawaii and all of the US sovereign territories (except Puerto Rico) was not available at the time of creation. Although data for Puerto Rico is present, it dates from before the 2017 hurricane season, so the current validity is questionable. This product will be updated as new data becomes available.

This feature class/shapefile represents electric power substations primarily associated with electric power transmission. In this layer, substations are considered facilities and equipment that switch, transform, or regulate electric power at voltages equal to, or greater than, 69 kilovolts. Substations with a maximum operating voltage less than 69 kilovolts may be included, depending on the availability of authoritative sources, but coverage of these features should not be considered complete. The Substations feature class/shapefile includes taps, a location where power on a transmission line is tapped by another transmission line.

Purpose: This feature class/shapefile is for the Homeland Infrastructure Foundation Level Database (HIFLD) https://gii.dhs.gov/HIFLD as well as the Energy modelling and simulation community.

The data consists of names, types, voltages, constraint status and national grid references for 56,865 electricity substations (33 kV or larger) in Great Britain in 2018. It was compiled from information on individual transmission or distribution network operator websites and interpreted to produce a classification of constraint status (where applicable). The data set was compiled from information on individual transmission or distribution network operator websites. The work was funded by the Natural Environment Research Council Award NE/M019713/1.

*** 7/19/22: This dataset and its accompanying map are no longer available since they are inaccurate and outdated.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.***

----------------------------------
Information describing the previously available dataset is provided in the rest of this metadata record for reference.
----------------------------------

The electric transmission network information consisted of transmission lines, with associated substations, designed to handle 60 Kilovolts or greater.

The Minnesota Electric Transmission Mapping Project developed two geographic information system datasets: transmission lines and substations. This metadata record describes both datasets.

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.

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.

The Minnesota Electric Transmission Mapping Project was a collaborative effort between the Minnesota Department of Commerce and the Minnesota Geospatial Information Office.

The California Energy Commission (CEC) Electric Substation geospatial data layer has been created to display the locations of substations in California. It contains point features representing transmission substations and some distribution substations in California. These substations are fed by electric transmission lines and are used to step-up and step-down the voltage of electricity being carried by the lines, or simply to connect together various lines and maintain reliability of supply. These substations can be located on the surface within fenced enclosures, within special purpose buildings, on rooftops (in urban environments), or underground. A substation feature is also used to represent a location where one transmission line "taps" into another. When used in association with the CEC Power Plant and CEC Electric Transmission Lines geospatial data layers, viewers can analyze the geographic relationships with the substation across utilities, counties and state. The data has been gathered from two sources - internal CEC data and the Department of Homeland Security's - Homeland Infrastructure Foundation-Level Data (HIFLD). The CEC data was created from a project spanning many years and was previously updated in 2016. The data was derived from utility companies and USGS topographic map. Some of the data was rectified from GE and Platts substation geospatial data. The sources for the substation point digitizing are including sub-meter resolution of Digital Globe, Bing, Google, ESRI and NAIP aerial imageries, with scale at least 1:10,000. Occasionally, USGS Topographic map, Google Street View and Bing Bird's Eye are used to verify the precise location of a facility.The substation data, as one of the CEC's California Energy Infrastructure spatial data will be used to: 1. Support the CEC/STEP/Strategic Transmission Planning and Corridor Designation Office in corridor study and transmission line siting; 2. Support the CEC staffs' various analysis by providing general geographic reference information; 3. Enhance communication between and among government agencies on emergency management, resource management, economic development, and environmental study;4. Provide illustration of critical infrastructure spatial data to the public or other agencies in hard copy format.
