Public Utilities Infrastructure Information for Minnesota
Use this site to find
data, maps and statistics that show information about Minnesota's
public utilities infrastructure.
2006: Wind speed, capacity factor and energy
production maps and wind speed GIS data.
database: A primary data source for the location of large
wind farms is the FAA's Obstruction Evaluation/Airport
Airspace Analysis database. Instructions: At the FAA website, select
"Download Archives" from the menu on the left. Then select
"Off Airport Cases", Region = AGL, then the year the permits
were filed (for the AGL code, we suggest starting with 1998
and going through 2008), then select the
download button. Repeat the process using Region = WTE for
2008 - the present (the AGL code includes many features
other than wind turbines; wind turbines were first treated
as a separate category with the WTE code in 2008). The data files
are in .CSV format; they encompass the U.S. so you will have to
select for the Minnesota facilities.
Virtual Hydropower Prospector: An online GIS tool
designed to assist in locating and assessing natural stream
water energy resources in the United States. The map shows "water energy
resource sites" (including high head, low head and microhydro structures), potential hydro projects, hydro
plants, transmission lines and substations, as well as a
number of reference layers.
No coal producing regions are in Minnesota
- National maps and GIS data
Transmission lines and substations
- Electric transmission lines and substations, 60 Kilovolts or
(2007 version; 2014 in-progress)
must be requested
- CapX 2020
project: A joint initiative of 11 transmission-owning utilities
in Minnesota and the surrounding region to expand the electric
transmission grid to ensure continued reliable service.
- Maps of new transmission lines under construction in Minnesota and the
surrounding region (under "Projects")
Upper Midwest Transmission Development Initiative final report
9/29/10: Regional transmission planning effort included Iowa,
Minnesota, North Dakota, South Dakota and Wisconsin. The report
includes two general maps of possible renewable resource areas and
potential transmission corridors.
- Minnesota Electric Transmission Planning:
map of planning zones
- Regional and national
- Detailed official statewide electric utility service area boundaries
are available. With funding from the Minnesota Public
Utilities Commission (PUC), MnGeo had the original paper
boundary maps scanned and converted them to a GIS format. The
PUC and electric utility companies operating in Minnesota have
reviewed the data, although some boundary changes are still
being updated and continue to be under review.
Xcel Energy: very generalized map of the company's service
areas in 8 states, including Minnesota.
- National Pipeline Mapping System (NPMS)
The NPMS GIS data set is overseen by the U.S.
Department of Transportation, Pipeline and Hazardous Materials
Safety Administration working with other federal and state
agencies and the pipeline industry. It contains the location and
selected attributes of the major gas transmission and hazardous
liquid transmission pipelines, and liquefied natural gas (LNG)
facilities operating in United States and other offshore
entities. Distribution of NPMS GIS data is limited to pipeline
operators and local, state, and federal government officials.
U.S. natural gas system map: available for purchase
U.S. natural gas atlases: available for purchase
Natural gas utility service areas
MnGeo is not aware of any maps or GIS data showing the detailed boundaries of
Minnesota's natural gas utility service areas.
- National (no areas are in Minnesota)
Water supply systems
Public water supplies are built and administered locally but there is
state (Minnesota Department of Health) and federal (Environmental
Protection Agency) oversight through the Safe Drinking Water Act and the
Minnesota Water Well Construction Code. MDH administers the federal
regulations and requires that all public water supplies – community and
non-community – report water quality information to them.
- Twin Cities
