What to Expect
Developing a wind / diesel project will require time,
patience, and a willingness to hire experience
•A long process (2 to 4 years) –Need a champion
•Will need help from people with experience
–Wind data analysis
–Geotechnical analysis
–Wind / diesel power system design / implementation
–Permitting / environmental experience
•Will be required to spend some money to insure that the
project has value to the community
•Need to become a mini-expert in wind systems to
understand the options
•Need the implicit support of the whole community
(including the people, government, power suppliers)
Initial Screening
Conduct an initial assessment using the data that you
have available to determine if it makes sense to invest in a
new system -does the project even start to make sense?
•Alaska wind resource map
•Alaska village electric load calculator
•Community discussion
•Looking at other options
http://www.eere.energy.gov/windandhydro/windpoweringamerica
http://www.akenergyauthority.org
Identify the criteria that you want
to use to assess the value of the
project.
•Capital cost
•Operational cost and volatility
•Environmental impact
•Community philosophy
3 years
Resource Assessment
Good resource data helps to ensure that
•Project meets economic goals
•System is properly designed
Need to collect some local data
•Install anemometer at a proper site
•Correlate data to long term data sets from
local airports, weather stations…
AEA anemometer loan program
http://www.akenergyauthority.org/programwindlanemometerloan.html
3 years
Load Assessment
Need to understand the current and future load in the community to
properly assess system options
Measured data (Collect data from the plant)
•PCE reported load data (provides a basic overview) -
http://www.akenergyauthority.org/programspce.html
•Typical days (how does plant power vary)
•Billing Records (then need to include losses)
•Power System Output
Estimated data
•Assess Households, Commercial and institutional loads
•Spreadsheet tools -Alaska village electric load calculator
Other Community deferrable & optional loads
•Water pumping, ice making, battery charging
•Thermal loads (heating and water)
Expected load growth
•Historic simple load growth
•New or planned facilities; schools, water projects etc.
Load management and energy efficiency

Pre-feasibility Study
What is the most economical way to supply the power
to meet the needs of the community
Desired Results
Basic power system design
Estimate of initial and O&M expense
Base line cost of alternatives
Yearly renewable production
Diesel displacement
Reduction in fuel consumption
need to be as realistic
as possible regarding
costs and equipment
performance
Results need to be discussed
with the community … should
the project go forwards?
3 years
Final Site Selection
Need to determine where the new equipment is
going to go …
Controls and other equipment
•Space within the power house
Wind turbines
•Land availability (Private / Public)
•Good wind site (on a hill, close to coast)
•Good ground (Geotechnical analysis)
•Proximity to power station
•Road access
•Access to distribution lines
Experience indicates that implementing a wind system as part of a
complete power system upgrade makes the most sense.
Again… Community involvement will be required
3 years
Identify Permitting Issues
Understanding what permits you will have to
contend with will help to determine the project
timeline and cost
•Endangered Species
•Avian studies
–Raptors, Migratory birds
–Review with interested parties (Fish and
Wildlife, Community)
–Start assessments as needed
•Visual studies –how will the project look
•Historical and archeological studies
•Wetland review
•FAA assessment
•NEPA environmental assessment

Planning for the Future
Making sure the system lasts as long as it is
supposed to...
•Finical sustainability:
Develop a financial plan to insure system financial sustainability
•Operation & Maintenance Guidance:
Develop a sound long term operation and maintenance plan for the
power systems including warrantees, long term service support
•Training Programs:
The proper design, installation, operation and maintenance of power
systems is dependent on the quality and training of the people used
to perform these tasks. A one time training will not suffice
3 years
Detailed Design and Cost Estimate
•What parts of the existing plant will need to be
replaced / upgraded
•What other power system improvements can be
completed at the same time
•Turbine specification / Identify manufactures
–Get quotes for different turbines
–Look at different options: Cold climate, tower types,
installation
–What limits are there on installation, size, foundation type
–History of company, Alaska involvement
•Conduct detailed system analysis and design
•Development of project timeline (shipping and
construction constraints)
3 years
Finding Project Funding
Identify funding opportunities
•Private -green tags, corporate loans, alternative funding
•Public –State and Federal grants, loans, bonds
Responding to request for proposals
•Follow the format and address all of the grant requirements
•All involved parties must be included; letters of support, MOU’s
•Play to your projects strengths
•You must address the projects deficiencies
•Play to the needs of the granting party
•Play it safe –you will not get negative credit for providing to
much information (within proposal limits )
•Always mention local, in-kind contribution -is usually required
•Have a good team with experience in wind/diesel, rural
construction and power system maintenance
•Consider consulting with a grant writer

Deploying Projects
There are basically two processes of
project implementation.
•Self developed (you or the concessionaire
does it)
•Request for Proposal (RFP) (you oversee
everything and others do it)
Key additional issues
•Equipment specification –what to use
•Foundation design
•Equipment integration design (storage,
stability)
•Grid stability/load flow analysis (especially
with wind turbine connected to distribution)
3 years
Final System Design and
Implementation
Determine final system requirements
Contract for design and
installation
•Identify critical issues
•Develop RFP for system
•Review proposals
•Oversee installation
•System commissioning
•Obtain manuals and
engineering drawings
In-house construction
•Analyze dynamic operation
•Produce engineering drawings
•BOS specification
•Order equipment
•Design and install foundations
•Instalation of system
•System interconnection
•Commissioning
Operating
System
3 years
Commissioning
Important step of the implementation process
•Insures proper project implementation
•Sets a baseline for power system operation
•Sets basis for warrantee and equipment service claims
Basic Steps
•Check of system components to be supplied
•Review basic system design
•Checklists for commissioning of different technologies
•Detailed review of system and its operation
•Written and signed documents expressing the results of the
commissioning process and detailing required service issues
Usually includes initial training on power system and
component operation
3 years
Monitoring and Remote
Access
•Allows oversight of system performance
•Enables real time system interrogation and
troubleshooting even when off site
•Can reduce maintenance and down time
•Long term monitoring of allows
–Assess warrantee
–Provide feedback on energy
usage
–Support the expansion of the
project when it is needed
–Improve system efficiency
–Documentation of benefits
3 years
Review
•Development of a community power system is not a
simple task –lots of steps
•Wind-diesel systems are complex and companies
with experience should be approached to assist
•The operation and maintenance structure should be
considered from the beginning
•Projects are develop in a step wise process getting
more detailed (and more expensive) as time goes on
•Identifying funding to cover both development and
implementation is a difficult hurdle
•System installation and commissioning are critical to
project life
•Collaboration of the whole community is critical
