There is no official definition of the term "community" in Alaska, and this department does not generally make formal determinations regarding whether or not a specific group of persons comprises a community. Communities currently listed in the database include all legally incorporated municipalities (cities and boroughs), all federally-recognized Native villages and all "Census-Designated Places" (recognized by the 2000 U.S. Census). The list also includes a number of other "communities" that do not come under these preceding classifications. There are numerous "place name" locations, named municipal neighborhoods and historical locales that are not included in the current community list. NA: Not applicable.

Why was the data set created?

The data provides engineers, consultants, planners, and resource managers with information on the location of rural community powerhouses in Alaska and identifies locations for further installation by other agencies. In rural communities throughout Alaska, electricity is generated by a small local "system" (generation and distribution) using diesel fuel at a cost that is three to five times higher than that in urban parts of the state. Of 200 rural communities, approximately half are served by cooperatives or another form of utility that performs under a well-established organization. Others are served by very small entities, many which experience technical and administrative problems due to lack of economies of scale and/or lack of specialized skills in the community.

    This dataset utilized information from the AEA energy plan resource matrix. Although the matrix itself is unpublished, potential resources including hydroelectric, in-river hydro, wind, solar, wave, tidal, biomass, geothermal, municipal waste, natural gas, propane, coal, diesel, coal bed methane, and nuclear were identified for each community. These potential resources are reflected in the community energy profiles in the document linked above.

  2. How were the data generated, processed, and modified?

    Date: 2009 (process 1 of 2)
    Powerhouse data was compiled from the four previous works listed above and their locations were converted to shapefile using ArcGIS 9.3 software.

    Data sources used in this process:

    • AEA and ACEP (2009)
    • State of Alaska, DCCED (2000)
    • AK DNR, LRIS (1998)
    • DCCED, LRIS (1998)

    Date: 2009 (process 2 of 2)
    Formal FGDC metadata (this document) was written for this dataset (K.R. Papp, AEA, 9-Jun, 2009). The dataset will be distributed online via the AEA website (<http://akenergyauthority.org/>) and the Alaska Energy Data Inventory (<http://akenergyinventory.org>).

  3. What similar or related data should the user be aware of?


How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

    Project locations were drawn from the nearest community, according to locations provided by the 2000 Census.

  2. How accurate are the geographic locations?

    Unknown. Community locations were drawn from the 2000 Census. However, the locations of statewide towns and villages listed in the Census were likely entered by latitude-longitude, digitized from USGS 1:250,000 quadrangle maps, and heads-up digitizing from USGS 1:250,000 maps based on relative positioning of digital hydrography and digital township lines. Many locations were later updated by snapping them to points in the USGSNAMES coverage obtained from USGS. See the "Lineage" section below for additional information.

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    This dataset includes geospatial information about the locations of the projects maintained by the Rural Power Systems Upgrade Program, Alaska Energy Authority.

  5. How consistent are the relationships among the observations, including topology?

    Polygon topology present and clean on appropriate data. Other data are line, point, or annotation data and do not require topologic relationships.


How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?
