      14 th Winter Cities WWCAM – Maardu 2010 Energy implications of climate change
    • Climate Change: Impacts for Energy 14 th Winter Cities WWCAM – Maardu 2010 14 th Winter Cities WWCAM – Maardu 2010 Bering Sea Gulf of Alaska Anchorage Cook Inlet
      • Major Challenges for Anchorage
      • Local fossil fuel reserves are running out
      • Need to reduce carbon footprint
    • Climate Change: Impacts for Energy 14 th Winter Cities WWCAM – Maardu 2010 14 th Winter Cities WWCAM – Maardu 2010 Bering Sea Gulf of Alaska Cook Inlet Currently over 90% of Anchorage power comes from natural gas from nearby Cook Inlet. Cook Inlet Southcentral Alaska faces imminent natural gas shortages for heat and electricity generation Anchorage
    • Cook Inlet gas production is in decline 14 th Winter Cities WWCAM – Maardu 2010 2007 Alaska Division of Oil and Gas, Production Forecast as of 2007 Source 2007 Annual Report 2026 Cook Inlet Historic and Projected Natural Gas Production 1958 - 2026 Under Development Ninilchik/Deep Creek All Other Swanson River Kenai/CLU McArthur River Beluga River North Cook Inlet Fortunately: Southcentral Alaska possesses a WEALTH of alternative energy options : - wind - geothermal - hydro - Underground coal gasification - tidal…… majority now under active investigation
    • Climate Change: Impacts for Energy 14 th Winter Cities WWCAM – Maardu 2010 14 th Winter Cities WWCAM – Maardu 2010 Bering Sea Gulf of Alaska Anchorage Cook Inlet
      • Anchorage is pursuing three strategies at the same time:
      • Alternative energy sources
      • Conserve / reduce energy demand
      • Increase efficiency
    • Wind: the Fire Island Wind Project 14 th Winter Cities WWCAM – Maardu 2010 Fire Island Cook Inlet
      • Fire Island Wind Farm :
      • Alaska’s first commercial scale wind project
      • 36 GE 1.5 MW wind turbines, total 54 Megawatt capacity
      • ~150,000 MW per year, enough to power 18,000 homes
      • Photo simulation of type of installation
      Project underway by Cook Inlet Regional Inc. (CIRI) Site is 3200 acres high wind resource proximity to grid expansion potential

    • Geothermal – Mt. Spurr 14 th Winter Cities WWCAM – Maardu 2010
      • Exploratory work began in fall 2009 to develop a geothermal power plant at Mt Spurr.
      • Potential to provide 50-100 MW output of electricity to the grid.
      State has completed a lease sale of 36,057 acres on south side of volcano for geothermal exploration. The successful bidder was Ormat Technologies. $3.3M for 15 of 16 lease tracts. 14 th Winter Cities WWCAM – Maardu 2010 Mount Spurr (11,070 ft) USGS map
    • Geothermal energy 14 th Winter Cities WWCAM – Maardu 2010
      • Ormat Inc., is a world-wide, vertically- integrated geothermal power provider.
      • Now exploring in search of a large geothermal field at Mt Spurr.
      • Natural reservoirs of hot water under pressure can arise in volcanic areas due to intrusion of molten magma and deep circulation of groundwater.  
      • Wells drilled bring high pressure steam to the surface
      • Steam drives turbines in power plant. 
      • Cooled geothermal fluid is injected back to the reservoir.
    • Underground Coal Gasification (UCG)
      • Cook Inlet Region Inc. (CIRI) is exploring a UCG project to fuel a 100 megawatt power plant.
      • Site is on CIRI lands near existing Beluga gas fields and infrastructure.
      • Permitting began in Oct 2009 to start resource assessment testing.
      • Power production could begin in early 2014.
      14 th Winter Cities WWCAM – Maardu 2010 CIRI Exploration Area Map from CIRI http://www.cirienergy.com/index.php/CIRI/proposed_project/ Anchorage UCG is a process that harnesses the energy of coal without mining, by means of underground combustion.
    • Underground Coal Gasification 14 th Winter Cities WWCAM – Maardu 2010
      • Two wells are drilled to the coal layer
      • An oxidant such as air injected at one well and starts a combustion reaction.
      • Heat and pressure gassify the coal.
      • The second well produces gas to the surface.
      • Produces ‘Syngas’ (synthesis gas)
      • This energy-rich gas product can be:
      • Handled and used like natural gas
      • Used to fuel a turbine to generate electricity
      • Upgraded or converted to make synthetic natural gas or liquid fuels
      Coal + H20 + O2+ heat = H2+ CO + CO2+ methane gases Graphic courtesy of CIRI http://www.cirienergy.com/CIRI_UCG_Presentation_2009-10-09.pdf AIR SYNGAS

    • Tidal Power in Cook Inlet 14 th Winter Cities WWCAM – Maardu 2010
      • Tides in Cook Inlet are the second highest * in North America.
      • A demonstration tidal project that will connect to the Fire Island intertie is in development.
      • Fishery and beluga whale impact studies in progress.
      • 17 MW capacity, enough to power 17,000 homes.
      • The project team is led by Ocean Renewable Power Company (ORPC).
      * The highest tides are at the Bay of Fundy in Canada, which has a tidal energy project also done by ORPC. Artist’s conception of the turbine used at the Bay of Fundy plant. Older engineering alternatives include vertical or horizontal axis cross-flow turbines, or oscillating turbines.
    • Anchorage Municipal Energy Initiatives 14 th Winter Cities WWCAM – Maardu 2010
      • As natural gas supplies and pressure decline, Anchorage faces the risk of not enough gas for customers at peak demand times this winter.
      • The City has responded with coordinated contingency plans.
      “ Take the initiative…to pursue…energy conservation… and… urge and encourage local residents… ” The Nuuk Declaration 2008
    • Encouraging Conservation
      • Drills to test preparedness.
      • Citizen campaign to conserve energy year round.
      14 th Winter Cities WWCAM – Maardu 2010 “ Energy Watch” Approximate Daily Gas Demand Summer Winter
    • A Challenge – too many utilities 14 th Winter Cities WWCAM – Maardu 2010 Background: Our Regional Energy Challenges “ The Rail Belt”
    • A Challenge – too many utilities 14 th Winter Cities WWCAM – Maardu 2010 Regional Energy Challenges
      • Six electric utilities serve the Alaska Rail Belt ---
      • ML&P, Chugach Electric, Matanuska Electric, Golden Valley Electric, Seward and Homer Electric
      • (The first three all serve Anchorage!)
      • Peak load in the entire railbelt is 900 megawatts.
      • (Elsewhere in the country, 900 MW would be considered a small utility.)
      • The need to combine utilities has long been recognized but challenging to achieve.
      • The State has prepared a draft Regional Integrated Resource Plan (RIRP) recommending combining the utilities and focusing more on renewable energy.
      • The Alaska Legislature and each utility must approve the plan.
      “ The Railbelt”
    • Progress – a shared power plant
      • A joint project between Chugach Electric and Anchorage Municipal Light & Power to build and share a new generation plant.
      • Joining forces for economies of scale, building new plant for efficiencies of more efficient, combined-cycle power generation
      • 183 MW - 70% Chugach; 30% ML&P
      • $300-$400 million
      • 25-30% more fuel efficient
      • Combined cycle 3 GE gas turbines with 1 steam turbine
      • Construction 2010-2012
      • Commissioned by 2013

    • Anchorage Sustainable Building Ordinance 14 th Winter Cities WWCAM – Maardu 2010
      • AO2008-93
      • All MOA public building construction is required to be
        • LEED Certified after July 1, 2009
        • LEED Silver after July 1, 2012.
      • Provides private sector incentives for LEED certified construction by permit fee reductions.
    • What is LEED? Leadership in Energy & Environmental Design
      • A green building rating system developed by the US Green Building Council (USGBC). Sets standards for environmentally sustainable construction.
      • USGBC is member of World Green Building Council, WGBC.
      • LEED organization does not extend outside the US, but the rating system is internationally recognized and LEED criteria are at times used internationally.
      14 th Winter Cities WWCAM – Maardu 2010
      • Certified buildings use resources more efficiently.
      • Cost of design and construction is increased.
    • LEED and Arctic Construction? 14 th Winter Cities WWCAM – Maardu 2010 Some LEED scoring criteria possibly more difficult or less relevant in Arctic construction?, e.g.
      • Windows – radiant heat loss
      • Materials specifications
      • Recycling building site waste
      • Waste water drainage?
      MOA early experience - Cost MOA building cost added by LEED certification is 20-25%, compared with reported average across the country of less than 5%. However green construction in the private sector is being significantly encouraged by the permit fee incentives.

    • Special concern of Mayor Sullivan: Homelessness, Chronic Public Inebriation
      • Like other winter cities, Anchorage must address homelessness and public drunkenness
      • About 3,000 people in Anchorage are considered “homeless”
      • About 400 people are considered chronic inebriates or substance abusers, and use a higher proportion of services
      • Sadly, Anchorage had over 12 fatalities of homeless people in 2009
      14 th Winter Cities WWCAM – Maardu 2010
    • 14 th Winter Cities WWCAM – Maardu 2010 Special concern of Mayor Sullivan: homelessness, chronic public inebriation
      • Mayor’s goals – “to reduce the death and violence rates to and among those who are currently homeless and have substance abuse issues, and to make our neighborhoods and parks a safe place for all those who work and reside in our city.”
      • This requires a long-term coordinated effort
      • Mayor Sullivan formed a Homeless Leadership Team, led by the city’s Department of Health & Human Services
      Special concern of Mayor Sullivan: Homelessness, Chronic Public Inebriation Mayor Sullivan would like to know how other member cities address these issues.
