Statewide Energy Issues

•In 2001 4.8 trillion BTU
of energy were produced
in Alaska
•Mostly from Oil and
Gas
•About 85% of the
oil Alaska produces is
exported
•Alaska is importing
about 30% of its
exported refined
petroleum back

Why Regional Development?
Access to capital networks
Access to networks that allow communities, regional entities, entrepreneurs and
businesses to share ideas and explore contracting opportunities
Access to a highly skilled workforce or to worker training programs
Hub-Cities acting as O&M training and supply centers
Job creation
Consortium of entities that is responsible for implementing regional wind
development able to offer management services.
Shared Risk, i.e. wind turbine bulk purchases, strategic development and construction
Long-term local commitment through shared resources(e.g. O&M, R&R.)
Regional Programmatic Environmental Assessment shortens development time and
reduces funding needs.
Wind Development Barriers
Wind Development Barriers
Economy –rural economy
characteristics
Infrastructure –The majority of villages are not connected to a road system,
they are only accessible via air and sea/river.
Wind-Diesel Hybrid Technology -The specialized design of
wind-diesel hybrid systems, is a niche application of wind generation technology that covers,
compared to large, grid connected wind facilities, a relative small market sector worldwide.
The major barrier is the limited specialized knowledge of the integration design and
associated equipment interactions, such as switchgear, and energy storage.
Wind Development Barriers -continued
Equipment -Current turbine development in the wind industry is targeted to
multi-megawatt wind generators. The application for these machines in rural Alaska
is limited due to electrical load demand, construction equipment, and maintenance
requirements. However, large size wind turbines are believed to be an appropriate
choice for larger rural load centers. For smaller applications the equipment choice is
limited. Two emerging trends for the Alaska market are visible. One market sector
caters towards decommissioned, refurbished wind turbines (50kW –500 kW). The
second market sector is the small to medium size new wind turbine sector (50kW-
100kW).
Wind Development Barriers -continued
Operation and Maintenance -The repair skill, spare part
availability, remoteness of location, complexity of system, and responsiveness of
technical support are factors that have to be taken into consideration in the decision
making process. A dedicated, long-term O&M plan is a key factor for a sustainable
project.Due to the difficulties in performing repairs during a long rural Alaska
winter or delayed delivery, the downtime for a wind system can be several months.
Technology Acceptance -A successful wind diesel system is a
community development project that requires support from the local leadership, the
residents, and the local utility. Extensive and early local outreach is a positive
contributing factor for a sustainable project (i.e. School classes, participation in Met -
Tower installation, town meeting presentations etc.).

Methodology
Database -Community name, Census area, Coordinates, Population, Fuel
Cost, Wind Class
Ranking -Wind 70%, Population 25%, Fuel Cost 5%
Filter –
o Filter I -The ranking results were equally divided into four categories, each
represent 25% of the total amount of ranked villages.
o Filter II -Population numbers were divided into eight groups of community size.
For each community the average and peak load was determined based on the FY2007 PCE
data.
An average load for each population category within the respective region was calculated.
Methodology continued
o Filter III -In the last phase a combination of low load and low ranking was applied
to determine the elimination of villages unsuitable for wind development.

Regional Load Demand in Developable
Communities
Although the load demand can only indirectly
support wind development projections, it servers as
a reasonably good first estimate to identify
potential installed capacity options. Additional
capacity can be estimated if services generated by
wind (i.e. heat, export) are desired.

Conclusion
Regional Development is preferred in areas with a high density of
developable project sites.
Regional Development has the benefit of industry clusters (access to
technology, knowledge, supply, local economy)
Alaska has several regions suitable for a regional development approach.
Identification of developable project sites serve as basis for further decision
making processes (i.e. for turbine supplier, regional government, state
government, support service supplier, training provider)
This study presents the technical basis for discussions about regional wind
development only. An actual implementation process has to be developed
with the input of all stakeholders.
Next Steps
Study Phase II –Detailed evaluation of regional
economic impacts.
Study Phase III –Development of a „best
practices guide‟ for the successful implementation of
a regional economic wind development initiative.
Timeframe: Approximate
6-8 months.
