HDR has been working with the City of Unalaska to develop alternatives that will allow the Pyramid Control Plant (PCP) to meet the Long Term 2 Enhanced Surface Water Treatment Rule (LT2) requirements. An analysis was conducted and presented in the Water Treatment Plant Phase I Analysis Design Recommendations Report, which recommended the use of ultraviolet disinfection as a secondary disinfection technique to be placed in a new addition at the existing water treatment plant site. This information was presented in the Water Treatment Plant Phase I Analysis Design Recommendations Report and reported to the City Council in November, 2008. After the presentation, the City Council requested that HDR use unspent study money on investigating use of an in-line turbine at the water treatment plant for energy generation as part of the upgrades to the new facility. To provide this conceptual study, HDRΙDTA established the following objectives to study the hydroelectric turbine equipment. ■ Determine if an in-line turbine-generator is technically feasible. ■ Provide basic capacity and energy projections. ■ Provide a high-level opinion of probable cost. ■ Estimate the required footprint for the turbine-generator and associated ancillary equipment. ■ Determine if the facility can provide single-phase power. The results of this conceptual study indicate that it is technically feasible to install in-line energy recovery turbine-generators at the Pyramid Creek site. The study provided conceptual analysis of a two turbine generator alternative for approximately 64kw, which would yield approximately 280 MWh of annual energy projection with a 50% utilization factor. The cost for a two turbine energy recovery system was estimate to be approximately $704,000 in 2009 dollars. This number is mid range in the values reported in a prepared for the Alaska Department of Community and Regional Affairs Division of Energy in 1997. This would require approximately 1,375 ft2 of building space. However, this building space is generous and provides for co- located space with the other treatment piping requirements for the new addition at the plant. The direct turbine footprint is likely around half of the space shown in the footprint estimation included with the report. This study only analyzed only a small in-line energy recovery system utilizing the existing water supply line and daily water demand. Additional power could be generated if additional water could be discharged during low demand periods; however, this discharging was not evaluated because of the increased FERC licensing that may be required for the discharge of unused water. Power usage was assumed for consumptive uses only and not transmitted to the grid. The Pyramid Creek Water Treatment Plant Conceptual Study is attached with the summary for more information on the use of a turbine for energy recovery at the water treatment plant.

As part of this upgrade, HDR|DTA was asked to perform a high-level conceptual study to evaluate the installation of an in-line energy recovery turbine-generator at or near the existing pressure reducing valves. In accordance with the City’s request, the objectives of this study are as follows: ■ Determine if an in-line turbine-generator is technically feasible. ■ Provide basic capacity and energy projections. ■ Provide a high-level opinion of probable cost. ■ Estimate the required footprint for the turbine-generator and associated ancillary equipment. ■ Determine if the facility can provide single-phase power. 1.2 Previous Studies HDR|DTA understands the following studies have been conducted to evaluate the potential for generating hydroelectric power at the Pyramid Creek site): 1.

Rural Hydroelectric Assessment and Development Study, Prepared for the Alaska Department of Community and Regional Affairs, Division of Energy, by Locker Interest LTD, Anchorage, Alaska, August 18, 1997. Section 1 Introduction 2 Draft A copy of the 1997 Division of Energy (DOE) study was provided to HDR|DTA. Listed below is a brief description of this study, along with conclusions pertinent to the Pyramid Creek site. The purpose of the 1997 DOE study was to review previous studies, conduct a high-level screening effort, and develop a database consisting of 1,144 potential hydroelectric project sites in Alaska. Of these sites, 131 were determined to have a benefit cost of 1.0 or greater, with no obvious technical and/or environmental constraints. Four of the sites were then recommended for further study, one of which was the Pyramid Creek site. According to the 1997 DOE report, the most economical options for developing hydroelectric capacity at the Pyramid Creek site were either 1) a 100 kW installation design to tie into the City’s existing water supply line and use only the City’s water supply demands, or 2) a 260 kW installation using the City’s water supply with additional water diversions. Table 1 lists the preliminary economic characteristics of both alternatives. TABLE 1 PRELIMINARY ECONOMIC CHARACTERISTICS FROM 1997 DOE REPORT Alternative Annual Energy (kWh) Capital Costs (1996 dollars) 100 kW 877,000 $400,000 260 kW 2,174,000 $1,283,000 1.3 Project Input and Assumptions ■ Project Sizing – HDR|DTA was instructed to assume only a small in-line energy recovery system utilizing the existing water supply line and daily water demand. Additional power could be generated if additional water could be discharged during low demand periods; however, this alternative was not evaluated because of the increased FERC licensing required for the discharge of unused water. ■ Project Understanding – HDR|DTA understands via Internet-based project research that the City diverts waters from the Icy Creek Reservoir (approximate average surface Section 1 Introduction 3 Draft elevation 518 ft) to a water treatment facility via a 24-inch-diameter, ductile iron pipe (class 52 cement lined) measuring approximately 4000 ft long. The water treatment facility is located around elevation 270 ft and contains various pieces of equipment and piping, including pressure-reducing valves. Waters from the treatment facility then proceed to a 40 ft tall, 2.6 million gallon treated water holding tank having a base elevation of approximately 290 ft. The City desires to evaluate the feasibility of installing an in-line energy recovery turbine-generator system with a modified water treatment facility. A schematic depicting HDR|DTA’s understanding of the desired energy recovery system is shown in Figure 1. ■ Flow Data – To estimate preliminary equipment sizing and energy/capacity estimates, the City provided HDR|DTA with average and maximum daily flows for the 2007 and 2008 calendar years (Appendix A). In addition, the City informed HDR|DTA via teleconference that the flows could vary at any time depending on downstream water demands. ■ Power Usage – According to the City, all power will be for consumptive uses only and not transmitted to the grid. ■ Consumptive Power Needs – The Pyramid Creek site currently has a 30 kW backup diesel generator that supplies power to the facility in the event of a loss of grid power. This demand will increase the addition of ultraviolet (UV) disinfection equipment in the new installment at the water treatment plant. The UV equipment is expected to have power loads ranging from 4 to 15 kW, but will depend on the manufacturer selected during the bid period. Section 1 Introduction 4 Draft FIGURE 1 UNALASKA TURBINE – EXISTING CONFIGURATION WITH ENERGY RECOVERY TURBINE GENERATORS 5 Draft Section 2 Preliminary Hydrology and Capacity Studies The fundamental process for generating electrical energy from flowing water between different elevations is to convert kinetic energy to electrical energy by means of a prime mover (i.e., turbine) connected to a generator, which is connected to an electrical load. The energy generated is a function of the weight of water, the quantity of water, and the elevation difference (excluding losses and efficiencies). As the first step in determining available energy (kWh) and capacity (kW), HDR|DTA performed a hydrology study to establish how much water is available to divert through a turbine and the hydraulic head associated with this flow. 2.1 Flow Duration Development Utilizing the 2007 and 2008 daily flow data provided by the City, HDR|DTA developed a flow duration curve that statistically projects future flows from past records. It should be noted that percent exceedance curves only represent the period of record and do not reflect future changes in water usage patterns. The results of this analysis are presented in tabular form in Appendix B and in graphical form in Figures 2, 3, 4, and 5. 2.2 Preliminary Capacity Studies The rated generating capacity can be approximated using the following relationship: C = Q x H x E / 11,800 Where: C = Generating Capacity, MW Q = Design Flow, cfs H = Design Head, ft E = Overall Efficiency, (assumed to be 0.86) Design Flow Using the flow duration curve presented in Figure 3, HDR|DTA selected a design turbine flow of 3.2 cfs for a single turbine-generator configuration. For a double turbine-generator configuration, the design flow was assumed to be 6.4 cfs. Section 2 Preliminary Hydrology and Capacity Studies 6 Draft Design Head The estimated net head was determined as follows: Elevation of Icy Reservoir = 518 ft Centerline Elevation of Turbine-Generator = 270 ft Downstream Water Tank Elevation = 326 ft Gross Head = 192 ft Assumed Head Loss = 8 ft Estimated Net Head = 184 ft Estimated Preliminary Capacity The rated capacity per turbine-generator was estimated to be approximately 40 kW.

It should be noted that during the next level of study, a more detailed evaluation would include a transient analysis to determine pressure rise within the water conveyance system in the event of a load rejection or rapid valve closure. A transient analysis was beyond the scope of this study. ■ The conceptual capacity and energy projections were determined to be as follows: – The estimated installed capacity of the two turbine-generator alternative is approximately 64 kW. – The average annual energy production is approximately 281 MWh, which represents a utilization factor of approximately 50 percent. ■ The estimated opinion of probable costs for the two turbine-generator energy recovery system, excluding civil related activities, is approximately $703,650 (2009). ■ The estimated footprint required for the two-unit alternative is approximately 1,375 ft2 (55 ft x 25 ft). ■ The Cornell microturbine units as proposed by Canyon Hydro produce three-phase power; however, it is feasible for the system to produce single-phase power via a small transformer.
