Electricity 

Updated:  Winter 2014 
Reader Recap: When that light goes on at the flip of a switch, it represents the balanced coordination of short and long term power purchases, power scheduling, and an array of local infrastructure, linemen, and engineers, that team to provide reliable power to our community and the lab.
Did You Know?  DPU is teaming with the New Energy and Technology Development Organization (NEDO) of Japan, Los Alamos National Lab and others to build a Smart Grid here which will include a photovoltaic array on the capped landfill.

Electric Production and Supply

In 1985 the DPU and the Department of Energy formed a power pool through an Electric Coordination Agreement (ECA).  This allowed the two entities to blend resources.  Los Alamos County's resources under the ECA are as follows:

    1. San Juan Generating Station Unit 4 (coal, 36 megawatts)
    2. Laramie River Station entitlement (coal, 10 megawatts)
    3. El Vado hydroelectric facility (hydropower, 8 megawatts)
    4. Abiquiu hydroelectric facility (hydropower, 18 megawatts)
    5. Los Alamos' Western Area Power Administration entitlement (hydropower, 1 megawatt)
    6. County transmission arrangements
    7. County purchased power contracts.

DPU also obtains a modicum of power from a local source, the 1 megawatt* photovoltaic array on the East Jemez landfill site.  The site was identified, then selected from a joint feasibility study on potential bright field location conducted by Los Alamos National Lab and DPU staff.  In a prtnership with LANL, and Japan's technology ministry NEDO (the New Energy & Technology Development Organization),  1 MW worth of solar panels are insalled on the landfill and producing energy as part of the Los Alamos Smart Grid (www.losalamossmartgrid.info) The DPU continues to explore options to add another 1 MW of photovoltaics to the landfill site.

    *Note:  Megawatt versus megawatt hour:  A watt is a unit of power. One megawatt is a million watts of electricity.  A megawatt hour is a million watts that were produced or consumed over an hour period. For example - one megawatt hour is enough electricity to power approximately 350 homes for an hour.  

    Renewable Electricity

    The DPU provides about 25 percent of Los Alamos and White Rock power from renewable resources and we're aiming for more. Through an entitlement with the Western Area Power Administration and the two County-owned hydroelectric facilities DPU provides clean hydroelectric power.  Additionally we offer our customers the option to purchase certified renewable wind power through Renewable Energy Credits purchased by LA Green.  We are embarking on a Smart Grid project which will include a 2 megawatt photovoltaic array to be built on the county's capped land fill (located on leased DOE land).  

       Distributed Solar Power

       Solar power generated by customers can offset utility bill charges for
       electricity.  Several ratepayers have explored the installation of solar
       photovoltaic arrays at their homes, and the DPU supports these endeavors
       through Net Metering, and guidance on the safe interconnection of
       customers' electric generation with the local grid.  Learn more here or 
       download the full Residential Solar Power packet.


    The DPU, in accordance with Board of Public Utilities' direction, and the 2013 Customer Survey's expressed preference (p. 71) explores, 
    intiates and executes upon renewable energy projects to steadily decrease the amount of power purchsaed from conventional coal-fired power sources.

Electric Distribution

Los Alamos County's electric distribution network provides power to more than 8,500 ratepayers.  Departmental priorites for maintenance and enhancements are assessed regularly.  While no Utility provider can ever guarantee that power will never be interrupted, the DPU has established a goal for itself to reduce outages to less than the System Average Interruption Duration Index (SAIDI) for communities of our size as determined by the American Public Power Association.   The APPA index for average, accumulated down time for a year that a customer could expect is 60 minutes.  To realize this goal the DPU developed an Electric Reliability Plan (developed in 2011 and updated in 2012) based off of data collected in the 2006 Condition Assessment and continuing system inspections.   

 

The Electric Reliability Plan

Reducing the frequency, duration, and number of customers impacted by power outages is the primary objective of the dynamic Electric Reliability Plan.  One key initiatives included in the Electric Reliabilty Plan is to address trees which may come into contact with overhead lines.  DPU has prepared a briefing on  Maintaining the Power Line Right-of-Way to keep our customers informed about safe distances between trees and overhead lines.  As an examaple fo the dnagers, recent wildfires in New Mexico  (Thompson Ridge and Las Conchas) were both instigated from tree/power line contact. 

Community knowledge and dialogue helps us to keep reliability initiatives prioritized correctly.  To this end we publish our monthly power outage report in the Board of Public Utilities agenda documentation which is available to the publicv.  Here's a link to the January 2014 outage report, which is based on the trailing 12 months of reliability performance.  It says, in essence, that our average power outage time per capita is less than 60 minutes.
