1st Inventory and Assessment Project Completed

Rural Power System Inventory & Assessment

Purpose & Background

Evaluate and Rank Rural Power Systems

Prioritize Assistance For Power System Upgrades

Rural Power System Inventory & Assessment

Purpose & Background 3 AAC 108.110 Eligibility for and authority prioritization of assistance, states that utilities, municipalities, school districts, unincorporated villages, community associations, Native corporations, councils organized under 25 U.S.C. 476, traditional councils, and other persons providing power or fuel to the public in one or more communities are eligible for assistance. To prioritize its assistance for power system upgrades, the authority will evaluate and rank deficiencies and needs for upgraded community power systems in each community in the state that (1) has a population of at least 20 but less than 2,000; (2) is not predominantly a military or industrial site; (3) has a central community power system; and (4) is not connected to the Railbelt (Homer-Seward-Anchorage-Fairbanks), Four Dam Pool (Glenallen-Valdez, Wrangell-Petersburg, Ketchikan, Kodiak), or Juneau power distribution systems. The authority may reevaluate and modify its evaluations and rankings based on changed assumptions or new information. The authority will publish and periodically update its rankings on its Internet web site. In providing assistance under 3 AAC 108.100 - 3 AAC 108.130, the authority will give priority to those communities found in the authority's evaluations and rankings under (b) and (c) of this section to have the greatest needs for assistance. The authority may revise its prioritization based on (1) requirements of federal or state agencies or other entities providing money; (2) the authority's determination of a recipient's readiness to proceed with the project; (3) the recipient's ability to meet conditions for assistance under 3 AAC 108.120; or (4) cost-effectiveness factors.

Analysis

Rural Power System Inventory & Assessment

Population

If the population is less than or equal to 20 then 0% is added to the score If the population is greater than 20 and less than or equal to 100 then 2.5% is added to the score If the population is greater than 100 and less than or equal to 250 then 5% is added to the score If the population is greater than 250 then 7.5% is added to the score

Maintenance (G=Good, O= OK, N=Needs Improvement)

If maintenance was Good then 10% is added to the score If maintenance was OK then 0% is added to the score If maintenance was Needs Improvement then 10% is subtracted from the score

Time Since Last Project (Years, 0 indicates no project has been done) If TSLP is 0 then 10% is added to the score If TSLP is greater than or equal to 1 and less than or equal to 4 then 2.5% is added to the score If TSLP is greater than 4 and less than or equal to 8 then 5% is added to the score If TSLP is greater than 8 then 10% is added to the score

3 Year Average % Of Line Loss (From PCE data. Used only evaluating distribution system) If 3 yr. A%LL is equal to “No PCE” then 5% is subtracted from the score If 3 yr. A%LL is greater than 0 and less than or equal to 10 then 5% is added to the score If 3 yr. A%LL is greater than 10 and less than or equal to 15 then 10% is added to the score If 3 yr. A%LL is greater than 15 and less than or equal to 25 then 15% is added to the score If 3 yr. A%LL is greater than 25 then 25% is added to the score
