This project demonstrates the use of flywheel energy storage to stabilize any village power grid. Grid stability is needed to achieve increased use of wind and other renewable energy sources in diesel mini grids. The proposed project consists of installation of a Powerstore flywheel energy storage system, along with a state of the art Distributed Digital Control System, to create a very high-penetration wind diesel system with residential thermal storage in Kongiganak, Alaska. The demonstration of this system will enable the effective sizing and cost reduction measures to be identified so that the system can be widely replicated throughout the state and other power systems throughout the country. Renewable Energy Fund Grant Application Round 3 AEA10-015 Grant Application Page 4 of 22 10/7/2009 2.5 PROJECT BENEFIT Briefly discuss the financial and public benefits that will result from this project, (such as reduced fuel costs, lower energy costs, etc.)  Total annual benefits are estimated to be in excess of $113,441. With 22,100 gallons of additional fuel displacement there will be 2700 reduced diesel operating hours at $5.25- $6.25 per hour. Simple pay back for the project would be 14.63 years. At 5% interest for 20 years these savings represent a NPV of $3,751,034. Annual benefits accrue over the wind heat case from additional fuel savings due to reduced operating constraints -11,189 gallons of diesel @ $5.00 per gallon = $55,945. HOMER analysis indicates 6630 hours of diesel operations costs @ $9.75/ will not be required =$64,642. The reduced usage of the diesel gensets results in double the replacement interval from 10 years to 20 years. At an estimated replacement cost of $160,000 for each of two gensets. 2.6 PROJECT BUDGET OVERVIEW Briefly discuss the amount of funds needed, the anticipated sources of funds, and the nature and source of other contributions to the project.

Puvurnaq Power Company (PPC) is a locally owned electric utility, owned by the Native Village of Kongiganak. It was ordained by the Kongiganak Traditional Council (KTC) in January 15, 1983 (Ordinance No. 99-06-2). KTC reserves the power and authority of PPC’s budgets, rates and its acquisition or disposal of real property. PPC has a 5 member Board of Directors to manage and operate the public electric utility. The PPC Board of Directors hires a General Manager to act as the chief administrative officer of the utility. The utility is operated from a fund separate from the general fund of the village. PPC holds a Certificate of Public Convenience and Necessity (No. 395) which was issued by the Alaska Public Utilities Commission, Docket No. U-87-71 (1), Date of Order – May 5, 1988, Executed June 1, 1988.

Additionally, weekly and monthly project coordination meetings will be held with the project team to track progress and address issues as they arise 3.6 Project Risk Discuss potential problems and how you would address them. There are inherent risks in any project involving construction, logistics, and unpredictable weather. These risks will be managed by implementing meticulous planning resources, with contingency built into the project schedule. The team of Intelligent Energy Systems and STG has experience managing the logistics of this project. Flywheels have yet to be used in Alaska, so there may be some perceived risk surrounding their implementation. This project has elected to use a flywheel system, the PowerStore, that has been successfully implemented in multiple locations, some very remote, in Australia, as well as in conjunction with wind resources on several islands in the Azores, managing unstable loads and fluctuating power sources. These systems have produced unprecedented levels of high penetration, and been tested to the utmost level of confidence.

Discuss the pros and cons of your proposed energy resource vs. other alternatives that may be available for the market to be served by your project. The wind resource in Kongiganak is well documented. One year of 30 meter onsite data was available and can be downloaded from the Alaska Energy Authority Website. The Kong site was selected by wind resource experts from the National Renewable Energy laboratory to provide a monitoring location which would provide regionally valuable data. The AEA website provides a complete wind resource assessment report. www.akenergyauthority.org/programwindresourcedata.html. The results of the wind resource evaluation indicate an outstanding wind resource with an average wind speed is 7.78 m/s, and with the power distribution well suited for the capture of wind energy. The AEA report gives an annual average temperature of 1.4°C, which at sea level corresponds to an air density of 1.286 kg/m³. The data was analyzed in the Homer model to and compared with the power curves of various candidate wind turbines. 4.2 Existing Energy System 4.2.1 Basic configuration of Existing Energy System Briefly discuss the basic configuration of the existing energy system. Include information about Renewable Energy Fund Grant Application Round 3 AEA10-015 Grant Application Page 10 of 22 10/7/2009 the number, size, age, efficiency, and type of generation. The existing system consists of five Wind Matic 17-S wind turbines on 80 foot lattice towers, and a new diesel powerplant. By July 1, 2010, the system will also include an energy recovery boiler at the washeteria for frequency control, a smart metering system, and 20 thermal stoves in the residences of village elders. The electric load data is displayed in the tables below and the following figure provides a profile of the loads which were used for this analysis. The load above includes an expected 15% load increase due to the new school which will be completed in 2010. This figure shows ten year the average load is estimated to grow from 107 kW (2003) to 175 kW, or 4188 kWh/day 2010.

Include a brief discussion of Renewable Energy Fund Grant Application Round 3 AEA10-015 Grant Application Page 12 of 22 10/7/2009 any impact the project may have on existing energy infrastructure and resources. The existing power plant supplies electrical energy supplied by the wind turbines, and diesel fuel burned in engine-driven generators to supplement wind power produced. Wind turbines offset a substantial amount of diesel previously burned, as well as supply energy to thermal stoves, which offset heating oil. 4.2.3 Existing Energy Market Discuss existing energy use and its market. Discuss impacts your project may have on energy customers. Kongiganak is located on the west shore of Kuskokwim Bay, west of the mouth of the Kuskokwim River. It is located in a marine climate. Precipitation averages 22 inches, with 43 inches of snowfall annually. Summer temperatures range from 41 to 57, winter temperatures are 6 to 24. Kongiganak is accessible only by air or by snowmachine in winter, and boat in summer, for delivery of supplies. Due to recent construction of a new school and a new runway, Kongiganak has experienced recent upgraded infrastructure. In a recent RUBA report, it was indicated that Kongiganak meets all Essential indicators, and most Sustainability indicators. Kongiganak relies on electricity to maintain home lighting, street lighting, telephone service, school service, clinic hours, and freezers to maintain a subsistence lifestyle. Reliable electricity is crucial to the residents of Kongiganak. 4.3 Proposed System Include information necessary to describe the system you are intending to develop and address potential system design, land ownership, permits, and environmental issues. 4.3.1 System Design Provide the following information for the proposed renewable energy system: • A description of renewable energy technology specific to project location • Optimum installed capacity • Anticipated capacity factor • Anticipated annual generation • Anticipated barriers • Basic integration concept • Delivery methods In the current Kongiganak diesel system, it is important to realize that not all of the power produced by the wind turbines can effectively utilized, especially at its highest value which is the displacement of diesel fuel used to meet the guaranteed consumer electrical load. This is true because a large proportion of the wind generated energy at all times must be dissipated to energy storage to preserve the stability of the system frequency and voltage. A flywheel energy storage unit eliminates the need to either dump wind energy or curtail wind production through its ability to symmetrically and instantaneously inject and absorb real energy into the power system as needed. The installation of the flywheel acts as a shock absorber making up for any changes in consumer load, variations in wind output, and diesel loading. The flywheel enables optimum diesel savings in three ways: 1. Limits system spinning reserve to 15 kW in all operating modes, thus eliminating the need for Renewable Energy Fund Grant Application Round 3 AEA10-015 Grant Application Page 13 of 22 10/7/2009 excess diesel capacity, and allowing operating gensets to operate at maximum efficiency, while reducing engine starts and stops, and standby losses. 2. Increases frequency and duration of high wind penetration diesel displacement by eliminating the restrictions on operating wind turbines during certain combinations of wind strength and load. 3. Increases economic value of the wind turbines. The average wind speed at Kongiganak is 7. 78 m/s per second. The typical wind turbine, such as the Windmatic or the Northwind 100 begins producing energy at a wind speed of 4 m/s and reaches full rated capacity at 14 m/s. The nature of the wind resource is such that 90% of the energy is produced at wind speeds below the rated capacity, while only 10% of the energy is produced at wind speeds below 7 m/s. This implies that in order to achieve significant fuel displacements estimated by the HOMER modelling, the wind system must be able to reliably meet full guaranteed electrical demand (consumer load, lighting, communications, electrical appliances, tools, motors, etc.) over fairly narrow band of wind speeds and time durations. HOMER modelling estimates that the full consumer electrical load would be met whenever the wind speeds exceed 8 m/s (16 mph), which is 60% of the time. However, in reality this level of performance is only possible with the addition of the flywheel or other form of real energy storage such as a battery bank. The HOMER model assumes that the wind diesel system operates over 15 minute or 1-hour time steps and that the wind turbines produce only at a guaranteed power level. In reality the equilibrium of the current and voltage, fluctuates along a sub second time frame and is subject to the random nature of the wind, instantaneous changes in consumer load, and the rapid variability of turbine output. The PowerStore flywheel instantaneously and symmetrically absorbs and injects real and reactive power to smooth out the variation and provide the guaranteed power level , firming the continuity of the wind supply Two types of control are possible with the flywheel system. These are dynamic and logistic. Dynamic control is required in the system due to the presence of multiple synchronous wind generators, and changing load requirements. Of greater value are the logistical control modes, which make decisions when to stop and start a diesel engine, start a wind turbine and turn on and off loads. The flywheel eliminates restrictions placed on operating the wind turbines during certain combinations of wind strength and direction and have been proven in locations such as multiple locations in Australia, as well as Portugal and the Azores Islands. To result in considerably increased operating hours for high penetration The service life of the mechanical braking system is likely to be reduced due to the enhanced frequency of grid losses. The addition of the flywheel eliminates or reduces the following operating constraints (conditions the power system must be met to represent a feasible operating mode) on the current wind diesel system. When modeled in Homer, the addition of the flywheel results in additional annual fuel savings of 22,100 gallons of fuel and diesel operating hours by 2700 hours, or $9.25 an hour, and a resulting annual savings of $110,500 over the current wind diesel case. The constraints are: 1. Operating reserve as a percentage of load 2. Operating reserve a percentage of annual peak 3. Operating reserve as a percentage of wind power output. Renewable Energy Fund Grant Application Round 3 AEA10-015 Grant Application Page 14 of 22 10/7/2009 4. Control averaging time for power generated power 5. Diesel low load set points. Operating reserve is the surplus generating capacity that is required at all times. The amount of operating reserve can be expressed as a percentage of load, percentage of annual peak load, and percent of wind power output. Operating reserve as a percentage of short-term loads. This is a diesel generation requirement, which defines a percentage of the total power output that must be covered at all times by diesel generation. This constraint is to provide enough real or reactive power in the event that the load increases suddenly or the power output from the wind dies suddenly. The higher the operating reserve is as percentage of load, the greater the amount of diesel generation that must stay on line, and thus the amount of excess generation capacity that will be shunted to thermal loads in wind operational modes. The flywheel fixes the operating reserve requirement under all conditions at 15 kW, which is half the current amount. Operating reserve as a percentage of annual peak. This defines the percentage of total power output that must be covered by the spinning reserve in the long-term. The constraint insures sufficient spinning reserve in the event the power output of the wind turbines continues to decrease over time, or the load slowly begins to grow. The flywheel eliminates the need for this setting, by providing real and reactive power to bridge system configuration changes, depending on how the settings are configured. The flywheel can provide both fast short term, and depending on the load, long term ride through support. The flywheel delays increase in diesel capacity. Operating reserve as a percentage of wind power output. Sometimes this is referred to as a margin of safety. This is a setting which determines how much available wind will be shunted to heating loads, or relied upon for “firm” capacity. This constraint ensures enough diesel capacity is available to meet the load in case of a sudden loss of wind power. The flywheel fixes this parameter at 15 kW and then directs any and all wind to meet the highest value loads. Without the flywheel, the first 100 KW of wind energy would go to heat dumps. Control Averaging time. The time over which each of the parameters is evaluated establishes the operational modes of equipment. This parameter has perhaps the greatest effect on fuel saving. The flywheel sets the optimum diesel configuration and allows the system to stay in that configuration and absorb all the wind that is available. The averaging time has the most significant impact in establishing long-term spinning reserve requirements, both in real or reactive power modes, which takes precedence in configuring setting to increase the percentage of wind versus diesel. The flywheel is especially valuable here as it enables the maximum penetration of wind at lower and medium wind speeds, where the wind turbine power output is most effected by small changes in wind speed. Diesel low load set points. The electronically fuel injected diesel engines are highly efficient across the full range of fuel setting, because fuel is managed so precisely. As wind penetration increases, less diesel fuel is injected into the cylinders. However, due to constraints on real or reactive power requirements, and the ability of the generators to accept large step loads, low load operation is currently limited to set points of 45 to 50% of rated capacity. The flywheel removes this constraint. HOMER MODELING RESULTS: are attached. Renewable Energy Fund Grant Application Round 3 AEA10-015 Grant Application Page 15 of 22 10/7/2009 Powerstore, flywheel based power station integration package. The PowerStore diesel power station integration package allows the PowerStore Energy Storage Flywheel to interact seamlessly with an existing automatic diesel power station, and consists of: Supply, electrical installation and commissioning of a PowerStore 300kW flywheel energy storage system with cold weather modifications; Supply and commissioning of a Powercorp Distributed Control System for four (4) generators, two (2) feeders, five (5) wind turbines, and one (1) “contractor driven” electric boiler, with algorithms to interface with metering controller for thermal stoves; Two (2) SCADA PC’s, data recorder and communications router for internet/telephone remote monitoring and control. Note that these PC’s are desktop PC’s and not touch screens; Engineering work required to make the DCS interface with the boiler and the Windmatic 95 wind turbines (specifications to be delivered to Powercorp; and Optional 5 year scheduled servicing of components. The Powerstore consists of a flywheel connected to a permanent magnet generator. Powerstore utilizes advanced power electronics interface to electronically decouple the rotational energy stored in the flywheel from the power grid. This configuration enables energy to be symmetrically absorbed and extracted from the flywheel rapidly and repeatedly over a wide range of rotational speeds, and power outputs. The Powerstore acts as a fast acting shock absorber to regulating real energy and reactive power to stabilize frequency and voltage as wind output and load fluctuate. The adjustments are made on a millisecond time frame, and enable the diesel system to reduce spinning reserve requirements. High Penetration Wind Systems To enable the advanced features of grid stabilization for high wind penetration systems, and maximum utilization of wind energy, the PowerStore system must communicate with the various system components on the grid to which it is connected. This is done through a system of distributed integrated controllers, which are placed on major system components, such as the diesel generators, wind turbines, and major load centers. These controllers overlay the existing control packages to create an integrated network. This network is driven by advanced software applications so each component in the system operates optimally and independently. The following monitoring modules are required in order for the PowerStore to perform correctly in High Renewable Penetration modes. Diesel Generator Monitors Small DIN-rail mountable monitoring modules are added to the existing generator controllers. These modules send information back to the PowerStore about the current state of the generator (running, stopped, on-line or off-line) as well as how much power the generator is delivering if it is on-line. Using a power transducer tapping in to existing current transformers (CT’s) and potential transformers (PT’s) the monitoring device is also able to inform the PowerStore how much power is being generated, as well as how much spinning reserve is available on-line. Renewable Energy Fund Grant Application Round 3 AEA10-015 Grant Application Page 16 of 22 10/7/2009 Wind Turbines Similar to the generator controller, controllers are mountable monitoring modules are required to be added to the existing wind turbines. These modules send information such as the state of the machine (running, stopped, on-line and off-line) and how much power is being generated back to the PowerStore. Commands can also be sent from the PowerStore in order to reduce the power output of the machine through pitch regulation and power set point control on some or to shut- down or start-up. The monitoring modules use industry standard Ethernet communication hardware to communicate back to the PowerStore, allowing many different modes of data transport to the wind turbine tower, including fiber-optic and wireless. High Renewable Penetration operation occurs under the following three distinct modes: 1. Diesel + PowerStore 2. Diesel + PowerStore + Maximum Wind Turbine 3. Diesel + PowerStore + Limited Wind Turbine Diesel + PowerStore Under this mode of operation, the PowerStore stabilizes the frequency and voltage by using its internal monitoring, as in the basic functionality case. Additional functionality enabled by the inclusion of the external monitoring includes the ability of the PowerStore to provide temporary spinning reserve for overload conditions of the power station. During an overload condition, which is sensed by the generator monitoring modules, the PowerStore will export power in order to reduce the load on the generator down to no more than 100% of their rated power. The automatic power station controller is expected to change the generator schedule in order to prevent the failure of the power system, should the overload continue for an extended time. This feature saves diesel fuel by reducing spinning reserve requirements and also by “peak lopping” short overload peaks will also reduce the number of engine generator starts and stops, configuration changes and maintenance on the generators. Diesel + PowerStore + Maximum Wind Turbine The Diesel + PowerStore + Maximum Wind Turbine mode operates as the Diesel + PowerStore mode, with the addition of the operation of the Wind Turbines. This mode has all of the previous functions, including no requirement for spinning reserve and the frequency and voltage fluctuation reduction. The PowerStore monitors the wind turbine output, however the wind turbines are run at their maximum output until the power output of the diesel generators is reduced below a preset parameter (usually 30% - 40% of prime power output, and through automatic selection and configuration). At that point the control system switches to the next mode with limited wind turbine output. Diesel + PowerStore + Limited Wind Turbine The Diesel + PowerStore + Limited Wind Turbine mode operates as the previous mode, with the Renewable Energy Fund Grant Application Round 3 AEA10-015 Grant Application Page 17 of 22 10/7/2009 addition of a control loop to limit the output from the wind turbines such that the diesel generators are never under-loaded – which is detrimental to both the stability of the power system and the mechanical operation of the diesel generators. The method of power limitation for the pitch controlled wind turbines such as the FL 600 machines, the output of the wind turbine can be limited in order reduce the amount of power generated without losing all of the power generated by the machine. The controller can also turn them off wind turbines one-by-one in order to maximize the amount of power delivered by the wind turbines without causing an over-power situation. Wind Turbine, Powerstore Diesel off mode: As the operators become more confident with the wind diesel operation, the Powerstore can be programmed for voltage support mode. In this mode the Powerstore would become the voltage and energy source for the system, and the diesel gensets could be shut off entirely. Demand managed devices The Wind Diesel Controller is capable of communicating with thermal storage devices , and can schedule and dispatch these loads to increase or decrease the penetration of wind. The heat recovery systems and demand-managed devices can be controlled in various ways, depending on the proportion of heat recovery load to the electrical load, and the level of control required. 4.3.2 Land Ownership Identify potential land ownership issues, including whether site owners have agreed to the project or how you intend to approach land ownership and access issues. The land for the project has been donated by the Qemirtalek Village corporation. 4.3.3 Permits Provide the following information as it may relate to permitting and how you intend to address outstanding permit issues. • List of applicable permits • Anticipated permitting timeline • Identify and discussion of potential barriers No additional permitting required. 4.3.4 Environmental Address whether the following environmental and land use issues apply, and if so how they will be addressed: • Threatened or Endangered species • Habitat issues • Wetlands and other protected areas • Archaeological and historical resources • Land development constraints • Telecommunications interference • Aviation considerations Renewable Energy Fund Grant Application Round 3 AEA10-015 Grant Application Page 18 of 22 10/7/2009 • Visual, aesthetics impacts • Identify and discuss other potential barriers No land use issues apply. 4.4 Proposed New System Costs and Projected Revenues (Total Estimated Costs and Projected Revenues) The level of cost information provided will vary according to the phase of funding requested and any previous work the applicant may have done on the project. Applicants must refer ence the source of their cost data. For example: Applicants Records or Analysis, Industry Standards, Consultant or Manufacturer’s estimates. 4.4.1 Project Development Cost Provide detailed project cost information based on your current knowledge and understanding of the project. Cost information should include the following: • Total anticipated project cost, and cost for this phase • Requested grant funding • Applicant matching funds – loans, capital contributions, in-kind • Identification of other funding sources • Projected capital cost of proposed renewable energy system • Projected development cost of proposed renewable energy system A capital investment summary of $1,661,368 is required to purchase and install a Powerstore flywheel grid stabilization and integration control module. The module will cost $1,102,800, and an additional $235,000 will be required to ship, and completely install the module. The module will require a pile foundation similar to that for the wind turbines and powerplant. Final engineering is required to complete electrical, mechanical and structural drawings. The total cost of the project is estimated to be $1,552,680. A contingency of 7% was added to address unknown, which always emerge in bush projects, for a total estimated project cost of $1,661,368. $1,495,231 in grant funds is being requested, and $166,137 in match will be from the community. 4.4.2 Project Operating and Maintenance Costs Include anticipated O&M costs for new facilities constructed and how these would be funded by the applicant. (Note: Operational costs are not eligible for grant funds however grantees are required to meet ongoing reporting requirements for the purpose of reporting impacts of projects on the communities they serve.)

Download the form, complete it, and submit it as an attachment. Document any conditions or sources your numbers are based on here. SECTION 5– PROJECT BENEFIT Explain the economic and public benefits of your project. Include direct cost savings, and how the people of Alaska will benefit from the project. The benefits information should include the following: • Potential annual fuel displacement (gal and $) over the lifetime of the evaluated renewable energy project • Anticipated annual revenue (based on i.e. a Proposed Power Purchase Agreement price, RCA tariff, or cost based rate) • Potential additional annual incentives (i.e. tax credits) • Potential additional annual revenue streams (i.e. green tag sales or other renewable energy subsidies or programs that might be available) • Discuss the non-economic public benefits to Alaskans over the lifetime of the project A capital investment summary of $1,661,368 is required to purchase and install a Powerstore flywheel grid stabilization and integration control module. The module will cost $ 1,102,800, and an additional $235,000 will be required to ship, and completely install the module. The module will require a pile foundation similar to that for the wind turbines and powerplant. Annual benefits accrue over the wind heat case from additional fuel saving due to reduce operating constraints, 11,189 gallons of diesel @ $5.00 per gallon = $55,945. HOMER analysis indicates 6630 hours of diesel operations costs @ $9.75/ will not be required =$64,642. The reduced usage of the diesel gensets results in double the replacement interval from 10 years to 20 years. At an estimated replacement cost of $160,000 for each of two gensets, ( 2 units -$320,000 every 10 years to two units every 20,implies a deferred replacement cost of $16,000 annually). Total annual benefits are estimated to be in excess of $113,441 Simple pay back for the project would be 14.63 years. At 5% interest for 20 years these savings represent a NPV of $3,751,034. This would indicate a benefit/cost ratio of ($3751034/$1661368 = 2.25). The non-economic benefits include reduced carbon emissions from offset diesel use and Renewable Energy Fund Grant Application Round 3 AEA10-015 Grant Application Page 20 of 22 10/7/2009 exposure to technical training for local residents for on-going maintenance of wind-heat system. SECTION 6– SUSTAINABILITY Discuss your plan for operating the completed project so that it will be sustainable. Include at a minimum: • Proposed business structure(s) and concepts that may be considered. • How you propose to finance the maintenance and operations for the life of the project • Identification of operational issues that could arise. • A description of operational costs including on-going support for any back-up or existing systems that may be require to continue operation • Commitment to reporting the savings and benefits Andrew Crow, from the University of Alaska Anchorage, is working with the Chaninik Wind Group to develop a regional wind system business plan, based on a cooperative business model. The primary elements of this plan include utilizing combined funding from the savings of displaced diesel fuel to pay for system maintenance, and overall administration. The greater the number of wind turbines and energy storage, the more fuel displaced, the more viable will be the financial strength of the group. One of the principles of successful operation will be to create a well paid job in each community to support the wind system operation, and to create a network of trained operators, one in each village, including Kongiganak, who can support each other. A proposed source of funding would be to allocate $.05 per kilowatt hour for wind production to the operation and support. Each wind turbine will conservatively produce 150,000 kWhrs annually. This would be $7500/turbine x 5 turbine = $37500 in additional wages to utility personnel. Another $.03 / kWhr would be dedicated to a replacement fund. However, a production bonus would be paid to the utility personnel for any kilowatt hours produced above 200,000 kWhrs per year. This production bonus would be $.10/kWhrs. This could be as much as $4000 per turbine or $20,000. The increased cost of turbine operations would be partially paid for through the turbine bonus, increased non-fuel operating costs provided in the PCE program, and through fuel savings. The customer would still see a significant decrease in electrical rates, as the current value of kilowatt of displaced fuel is in the range of $.30/kWhr. The overall business plan would be administered by the Chaninik Wind Group with the assistance of the automated meter reading and information technology systems. In each village the system would be administered through the use of prepaid meters. The business plan when developed will provide a detailed management and financial plan, and outline utility performance standards. SECTION 7 – READINESS & COMPLIANCE WITH OTHER GRANTS Discuss what you have done to prepare for this award and how quickly you intend to proceed with work once your grant is approved. Tell us what you may have already accomplished on the project to date and identify other grants that may have been previously awarded for this project and the degree you have been able to meet the requirements of previous grants.

Dealing mainly in rural Alaska, the company has played a major role in high profile projects such as wind energy installations, communication tower installations, and community bulk fuel and diesel generation upgrades, to name a few. STG specializes in remote project logistics, pile foundation installations, tower erections, and construction management. STG takes pride in its wealth of experience, gained from years of work throughout “bush” Alaska, and through its ability to deal with the diverse and challenging logistics and conditions which it encounters on nearly every project it undertakes in remote locations.  Company Overview In 1996, St. George Construction was incorporated as STG, Inc. Since incorporation, STG has become the preferred construction management company for both the Alaska Energy Authority (AEA) and the Alaska Village Electric Cooperative (AVEC). Many of the projects executed by these two entities are managed and constructed by STG. STG’s core competencies include bulk fuel systems, power plant construction (both modular and steel-framed), wind farms, and pile foundations (driven piles, post tension rock anchors, helical anchor systems, freeze back, and active refrigerated piles). STG is the prevalent pile foundation contractor for Interior and Western Alaska. Additionally, STG has expanded to become United Utilities’ preferred contractor for its “Delta Net Project”, which involves the installation of communication towers and related equipment throughout the Yukon Kuskokwim Delta. STG has achieved this preferred status by demonstrating competitive rates and the ability to perform in remote locations with extreme logistical challenges. Qualifications The STG team has developed and maintained the capacity to manage projects through a set of key deliverables to ensure appropriate management of jobs across the complete project cycle including: • Provision of a quality project at a fair and reasonable price • Timely delivery within budget • Safe and professional performance on all work • Positive relationships with clients to ensure that project deliverables are met • New modern equipment that results in high productivity • State of Alaska Professional Land Surveyor (Reg. 10192) on staff with modern Topcon GPS Control through Detailed Project Planning STG focuses pre-construction efforts on planning and preparation. A project team is identified which includes management, administrative, and field supervision personnel. The team establishes budgets, c. has grown and developed into a p production targets, a master construction schedule, and detailed work plan for each project. The planning process involves key supervisory personnel as all aspects of the project are analyzed with particular attention to logistics, labor and equipment resource needs, along with specific material requirements. This results in a clear understanding of the goals of the client, the ontractual requirements, scope of work, and entification of potential obstacles that may impact ion of the job. ough to the administrative level , accurate documentation and reporting, and on to the field level where clear goals of roduction and quality are reinforced through the superintendent’s and foremen’s daily huddles and ost Containment anagement decisions.
