Business Meeting Meeting Date: 01/16/2024 Length (in minutes): Consent Item Agenda Title: Pavement Management Program Engineering and Inspection Services Authored By: Toni Riccardi Presented By: Project Manager Nichole George Item Type: Motion Requested Local Contract Review Board Public Hearing No Newspaper Legal Ad Required?: Public Hearing Publication 10/13/2023 Date in Newspaper: Information EXPLANATION OF ISSUE The purpose of this action is to award a contract for engineering and inspection services under the city's Pavement Management Program ACTION REQUESTED Staff recommends the Local Contract Review Board award the contract for engineering and inspection services under the Pavement Management Program to Wallis Engineering for an estimated amount of$3,300,000 over five years and authorize the City Manager to take the steps necessary to execute the contract. BACKGROUND INFORMATION The city's yearly Pavement Management Program (PMP) helps protect the city's investment in our street infrastructure. The program typically includes a combination of minor maintenance projects (slurry seal applications) and major maintenance projects (pavement overlays) that help prolong the life of our streets and maintain our Pavement Condition Index (currently at 82). Under the program,the city averages fifteen miles of crack sealing and slurry seal and one mile of pavement overlay and ADA ramps each year. The city's annual pavement marking work also falls under the Pavement Management Program. The contract before the Local Contract Review Board tonight is for design and engineering services related to the program. Work included under this contract will include: • Evaluation of existing pavements; •Recommendation of pavement treatments (overlay thickness,grind-and-inlay,etc.) to be used; • Evaluation of existing curb ramps; •Design of curb ramp retrofits to meet ADA requirements; • Survey work as necessary; •Design of paving work; •Design of street striping and marking; • Coordination with utilities and other agencies; • Preparation of final plans and specifications; • Establishing provisions for recovery of survey monuments and replacing monuments as necessary; • Construction management; and • Construction testing and inspection. As this work must be completed by an engineering firm,it falls under the Qualification Based Solicitation (QBS) process (Tigard Public Contracting Rule 70.016). The city issued a Qualification Based Request for Proposal for the project on October 13,2023,with the notice published in the Daily Journal of Commerce. Upon closing,the city received two proposals (and their respective qualification scores out of a possible 275): •Wallis Engineering. (251 pts.) •Harper Houf Peterson Righellis,Inc. (237 pts.) After the qualification scoring based on the identified criteria in the RFP (2024-05) the proposal from Wallis Engineering,as you see above,was found to be the top ranking firm,based in part on their previous work with the city. As such,and in accordance with Tigard Public Contracting Rule 70.016B.5.A,the city entered into negotiations with Wallis Engineering for contract pricing. The city and Wallis Engineering were able to reach an agreed upon price for the work and it is presented to the Local Contract Review Board tonight. As this work fell under the Qualification Based Solicitation process and a cost was agreed upon between the city and the top-ranking firm,the city did not need to request pricing from the other firm (Tigard Public Contracting Rule 70.016.B.5.)The contract will be for four years with one additional one-year option.The cost of the contract for the first year is estimated at just over$615,000. Using an annual increase (the contractor will be able to request an annual increase tied to the CPI) estimate of three percent, the total estimated cost of the contract over its possible life (five years) is just under$3,300.000. ALTERNATIVES&RECOMMENDATION The Local Contract Review Board may reject this contract and direct staff to issue a single year contract only and resolicit the work each year,which would result in additional costs for additional procurement processes. ADDITIONAL RESOURCES The Local Contract Review Board last awarded a contract for this work on October 13,2018. Fiscal Impact Cost: 3,300,000 Budgeted (yes or no):Yes Where budgeted?: Street Maintenance Fund Additional Fiscal Notes: Additional Fiscal Notes:The proposed contract is estimated at$615,000 for the first year of the contract. Each additional year is eligible for a CPI-tied rate increase leading to an estimated total contract cost of$3,300,000 over five years. Attachments No file(s)attached. AIS-5314 5. Business Meeting Meeting Date: 01/16/2024 Length (in minutes): 60 Minutes Agenda Title: Building Resilient Infrastructure and Communities-Tigard Library Microgrid Authored By: Gary Pagenstecher Presented By: Project Planner Gary Pagenstecher Item Type: Motion Requested Resolution Public Hearing No Legal Ad Required?: Publication Date: Information EXPLANATION OF ISSUE The City of Tigard Resiliency Initiative is a microgrid feasibility study. It is being conducted to learn more about pre-disaster energy resilience in Tigard through the installation of microgrids at three scales: 1) at the Tigard library to support resilient operation of the back-up emergency operations center(EOC);2) at the neighborhood scale for community solar and publicly accessible energy and services;and 3) at the district-scale, for resilience plus climate benefits,and economic development. This presentation continues the July 11,2023,briefing on the Initiative and will share findings and recommendations of the Library PV and Battery Microgrid Feasibility Study(attached),prepared by our consulting engineer PAE. Project partners also include the Energy Trust of Oregon and Portland General Electric,and Tigard staff from multiple departments.These stakeholders will be present to provide perspectives on the Initiative's proposed library microgrid and answer any questions Council may have. PAE's study identifies distributed energy resources (DERs),including photovoltaics (PV) and battery energy storage systems (BESS) and existing fossil-fuel based generation capacity,for facility and community resiliency through an "island-capable"microgrid control system at the Tigard Library.The analysis explores the implementation of a microgrid system for both the purpose of peak load shedding and resilience scenarios of varying durations in which the library is used as an EOC,as a heating and cooling center,and whole building operations. Development of renewable energy at the Tigard Library supports the City's goal to be carbon neutral by 2050.The BESS design developed in cooperation with Portland General Electric will leverage the utility's "Schedule 200"battery incentive program which allows the utility to control the BESS for grid support during on-grid operation.The microgrid system provides both local and regional resiliency and sustainability benefits. Provisions for the future Microgrid system have been incorporated within Facilities projects currently underway at the library,which include HVAC equipment upgrades,lighting system upgrades,and a new gas generator.The scope of this coordination provides space and pathways for future electrical components needed for a microgrid system. Coordinating with the city's internal Engineering team has also taken place to accommodate the Fanno Creek trail extension project schedule.Due to supply chain issues,two of the three HVAC air handlers still have not arrived and are not due until May of 2024.The silver lining of these unexpected delays is the ability to ensure Microgrid compatibility and build construction efficiencies into the design of the HVAC project. The microgrid system cost estimated by PAE at$3.41M has been reviewed by ETO's Trade Ally,A&R Solar,through ETO's Development Assistance program.The A&R Microgrid Report verifies equipment specifications and estimates pricing for those specifications at$3.92M (attached).A roof replacement is anticipated to be a part of the project to match the 25-year life expectancy of the solar PV installation and is estimated to raise the total project cost to $6M. Implementation funding is expected to include an assortment of grants and contributions from project partners and take advantage of the investment tax credits available under the Inflation Reduction Act. In support of the fundraising strategy,staff has prepared the attached Resolution for Council's consideration and adoption (attached). ACTION REQUESTED Receive project update, adopt the proposed resolution,give staff direction. BACKGROUND INFORMATION Dates of Previous and Potential Future Considerations July 11,2023 - first project briefing. Staff provided background about microgrids,resiliency, sustainability and the rationale for the three-tiered study. Councilors expressed general support for the project and specifically expressed interest in engagement. Public Involvement In addition to the July 11 briefing,the microgrid project has been mentioned at multiple Council meetings. The project has most recently been the subject of a CD climate action engagement meeting in December. In early 2024, staff will implement a public awareness campaign for the library microgrid project with a project web page and in coordination with library education and program staff.After the project is installed and commissioned,an interactive system performance display monitor,which is part of the PAE system design,will be prominently located in the library lobby to engage and inform the public. Impacts (Community,Budget,Policies and Plans/Strategic Connection) The project is responsive to the Council's 2023-25 goal to address climate change by reducing the city's carbon emissions and prioritizing carbon responsibility in city operations. Implementation of this high-visibility project at the city library will contribute to building understanding of the city's climate work and how the organization is supporting it;and build awareness in support of residents'own carbon emissions reduction. Specifically,the microgrid project will begin implementation of the 2019 Climate Resiliency Plan's strategy to lower GHG emissions by expanding distributed energy resources in the city to 50MW by 2030. Budget savings from the microgrid project are expected from the energy generated by the library solar PV system and by use of the battery and controller for both demand management and controlling the time-of-day energy is purchased when energy prices are lower. The library microgrid project will provide energy resilience during grid failure,a key to ensuring the city can provide continuity of emergency response services. ALTERNATIVES& RECOMMENDATION Adopt the Resolution in support of the Tigard Library Microgrid and its funding plan. Alternatively, council can accept the Tier 1 Microgrid report without taking a formal action,or can ask that staff return to council at a later date with additional information. ADDITIONAL RESOURCES Fiscal Impact Cost: $6 Million Budgeted(yes or no): No Where Budgeted (department/program):TBD Additional Fiscal Notes: Implementation funding may include grants (FEMA Building Resilient Infrastructure and Communities, ODOE Community Renewable Energy Program),PGE's Aid in Construction investments through enrollment in the Distributed Standby Generation Schedule 200 program,PGE's Renewable Development Fund, a portion of the city's Pandemic Relief funds allocated to Climate Resiliency Plan implementation,and application of the Inflation Reduction Act's Investment Tax Credit for 30%of eligible costs.

June 9, 2023 1.3 Codes and Standards The following codes, guidelines, regulations and other references that were considered in the design of the microgrid system and associated components. The list below is provided for reference only and is not a guarantee of Code compliance. — 2020 Oregon Electrical Code — 2022 Oregon Fire Code — National Fire Protection Association (NFPA) Standards — American National Standards Institute (ANSI) — Institute of Electrical and Electronics Engineers (IEEE) — National Electrical Manufactures Association (NEMA) — Underwriters Laboratories (UL) 1.4 Owner Specific Requirements PAE was asked to consider the deployment of a single building microgrid at the Tigard Library, which is an existing facility at 13500 SW Hall Blvd. The list of owner requirements was as follows: 1. Microgrid to support full building load for standard to major outage durations with the intent to operate the library as a warming or cooling center during daylight hours. For catastrophic outages, the intent is to support a sub-set of facility loads to operate as a backup Emergency Operations Center. For additional information on the defined outage durations, see Section 2.5 below. 2. PAE's microgrid design needs to consider infrastructure and energy use impacts of the upcoming Chiller Plant Upgrade scope of work, which is currently underway. 3. Utilization of a 500 kW natural gas generator that is slated to be installed as part of, or subsequent to, the Chiller Plant Upgrade but prior to the FEMA Tier 1 microgrid project construction scope. 4. The existing gas-fired boilers at the library should be assumed to remain through the microgrid project construction scope. 5. Microgrid scope should include development of renewable energy production on site via deployment of photovoltaics. Development of renewable energy at Tigard Library supports the City's goal to be carbon neutral by 2050. 6. The open space on the north side of the Library is to be reserved for development of new covered storage facilities and space for battery energy storage system (BESS) deployment and should not be evaluated for photovoltaic system siting. 7. BESS design should be developed in cooperation with Portland General Electric (local Utility) to leverage the utility's"Schedule 200" battery incentive program which will allows the utility to control the BESS for grid support during on-grid operation. 8. Any current or future electric vehicle charging should not be considered in Net Zero Energy calculations. The existing two electric vehicle chargers should be supported under full load microgrid operation of the library microgrid. No new electric vehicle infrastructure is to be included in the microgrid development scope. 2 June 9, 2023 ::1: ilii 2. 0 Energy Performance Analysis 2.1 Introduction The Tigard Microgrid project analysis for FEMA Tier 1 is to explore the implementation of a Battery Energy Storage System (BESS) and Solar PV array for both the purpose of peak load shedding and a resilience scenario in which the library is used as an Emergency Operations Center (EOC). A calibrated energy model was developed to analyze the hourly trends of the current library for this analysis. This section describes the energy modeling approach and inputs used for the analysis. Electricity demand data at 15 minute intervals for the meter at the library was received from PGE. This data was used to create a calibrated model that matches the hourly profile and demand as closely as possible. This calibrated model used the inputs seen throughout this section. The exception is that the calibrated model uses existing conditions at the time of the PGE meter data which includes packaged DX units for cooling. It is currently planned that these units, which are at end of life, are to be replaced with a new air cooled chiller within the next year. Because of this, all analysis shown throughout this report represent the energy and loads potential with the new air cooled chiller and added AHU-4 for the entrance lobby. The following scenarios were simulated as a part of this analysis: Table 1: Modeled Scenarios Scenario Model parameter Normal Library operations running typical hours and loads. Model calibrated based on PGE operations electric meter data. Existing Packaged DX cooling replaced with planned Air-cooled chiller design that is anticipated for installation in the coming year. Emergency Library operations running 24/7 in EOC spaces only, all other spaces considered shut Operations down and not open to the public. EOC spaces include community space, adjacent Center(EOC) restrooms and pantry, and entrance lobby space. Equipment loads and occupancy densities updated to reflect changing operations during an EOC scenario. Existing Packaged DX cooling replaced with planned Air-cooled chiller design that is anticipated for installation in the coming year. The shaded areas in green in the image below shows the areas operational during an EOC scenario. All other areas outside of the EOC area are assumed to be in use only during normal operations scenarios.

Load profiles for equipment, lighting, and occupancy meet typical use and diversity of a library space use. The hours of operation for the Tigard library are seen in the following list. The HVAC systems and electric load profiles are set to meet these hours throughout the year, minus holidays. Note that load profiles extend outside of these hours for employees that are in the building before opening and after closing. — Monday - Thursday: 10:00 AM to 8:00 PM — Friday - Sunday: 10:00 AM to 6:00 PM The following figures show the typical daily profiles for the library used in the energy model during normal operations.

Hour of Day -Mon-Thurs Fri-Sun Figure 7: Occupancy Load Profile BUILDING USE DURING EOC OPERATIONS During an EOC event, the energy model operations and load profiles will differ significantly. Library operations are set to run 24/7 in EOC spaces only, all other spaces considered shut down and not open to the public. EOC spaces include community space, adjacent restrooms and pantry, entrance lobby space, and 1St floor IDF room. Equipment loads and occupancy densities updated to reflect changing operations during an EOC scenario. 1 June 9, 2023 '::: : iiii:::::: The current design of the library shows that the 1St floor IDF room is served by a terminal unit connected to AHU-1. This IDF room would need to be operational during an EOC scenario. Therefore, it is recommended for resiliency to add a single zone mini-split system or similar to this space to both eliminate the need to operate AHU-1 during an emergency event and to reduce energy during normal operations. All EOC model simulations include that the 1st floor IDF has been decoupled from AHU-1 with a mini-split heat pump for independent cooling. The following table details the equipment to be needed during an EOC scenario separated by Community Space equipment and cooking equipment for the pantry.

The following chart shows the annual demand for the 2022 calendar year. 200 3 v g t� lao sa 671 11111 1401 3201 4001 4801 1:411 1 111 110: 8001 Hour of the Year Figure 8: Annual Hourly Electric Load Profile As can be seen from the chart above, electricity use is higher in the summer for building cooling use. Heating for the library uses natural gas fired boilers which keeps electricity in winter months lower. Gas use for the project is based on typical CBECS (Commercial Building Energy Consumption Survey) benchmarking data for a library building type, however, gas is not used as a part of the resiliency analysis. The table below shows the annual electricity use for the historic PGE data for 2022 calendar year.

Analysis focused on three levels of outage: standard, major, and catastrophic. The distinction between each outage type being the length of the outage. A standard outage we defined as a single day outage, a major outage we defined as up to 7 days and a catastrophic outage we defined as 2 weeks or more. The goal of the analysis being to understand how the overall system would perform in the absence of grid power. PAE took a two-fold approach in our analysis of the design options for the Tigard Library Microgrid. First, we explored a range of options for photovoltaic (PV) array integration at the library using Helioscope. We explored several rooftop PV design options and the use of ground-mount carports for additional PV capacity at the project site. After we had a thorough understanding of the PV options available on the site, we then turned to battery sizing. PAE used two primary tools to conduct our analysis of the battery size including a proprietary "Resiliency Tool" created by the engineers at PAE and we employed Homer Grid to analyze the economic feasibility of the different options we explored. PAE's proprietary tool focuses on the electrical system itself and helps determine the appropriate battery size to serve a facility electrical load without addressing any economic constraints. Once we had selected a range of battery sizes using the PAE resiliency tool, we then ran the analysis in HOMER Grid to determine the economics of each choice. HOMER Grid also allowed PAE to import the results of the analysis in Helioscope so that the entirety of the microgrid design PAE created could be analyzed together. In addition, HOMER Grid allows the creation of complex electrical pricing schedules as part of its analysis framework. PAE, in partnership with the PGE, recreated the utility rate schedules impacting the cost of grid energy at the library as part of PAE's economic analysis. PAE completed two reports for the City of Tigard. The PV Analysis Report can be found in Appendix A. The Battery Energy Storage System (BESS) Analysis Report can be found in Appendix B. Together, these two reports were utilized to determine the best and most economically feasible approach to creating a microgrid at the Tigard Library. June 9, 2023 ,""' SolarEdge PV inverters and Canadian Solar PV panels are the basis of design for the PV arrays proposed. And the battery based microgrid solutions from ELM Microgrid are the basis of design for the microgrid controller and battery energy storage system. For full details see the reports in the appendix. The last piece of analysis in the microgrid design focused on how the library electrical loads could be managed in the case of the three outage cases explored. PAE worked with city staff to determine which control systems could be integrated into the microgrid controller and which could not. The final control solution for building load management during a grid outage will incorporate limited automation between the microgrid controller and the facility Building Automation and lighting control systems but will be dependent on manual load shedding by City Staff to achieve resiliency for the major or catastrophic outage conditions. See Section 3.3 below for additional information. 16 June 9, 2023 3 .0 Electrical 3. 1 Electrical Service & Distribution The facility receives power from PGE through an underground utility feeder via an 800 amp 480Y/277V, 3PH, 4W service. The existing secondary service lateral routes to the main switchboard MDP-A, which serves a secondary main switchboard, MDP-B, on the second floor of the building. MDP-B then serves all branch circuit load panels in the building. MDP-B also currently serves 2 ATS switches designed to operate the generator in the case of emergency. The building is equipped with a 50kW backup generator. The city is currently undertaking a generator upgrade project to replace the existing 50 kW natural gas genset with a 500 kW natural gas genset. PAE's microgrid design includes the upsized 500 kW generator which will continue to serve as an emergency power source but will also be enabled for full load building backup as a microgrid controlled asset. The microgrid scope of work includes a new main service switchboard (4RDP-0) and will intercept the existing utility service lateral into the building and serve as a point of common coupling (PCC) for all distributed energy resources (DERs). The 4RDP-0 board will house the microgrid interconnect device controllable circuit breaker to establish the island mode operation of the local electrical power system in the event of a grid outage. The existing MDP- A and MDP-B switchboards will be re-fed and remain in service. The 4RDP-0 switchboard will be rated for 2000-amp service to support the code compliant interconnection of the on-site DERs and to provide full export capacity of the BESS power to PGE for grid stabilization and support services as required for Schedule 200 program participation. PGE will perform an analysis to determine if replacement of the main service transformer is required if the project moves forward with construction and utility service reconfiguration. The complete schematic design for the library power system configured for microgrid operation can be seen in the single line diagrams (SLDs) in Appendix C. SLDs include the necessary demolition of existing power system components as well as the new system components and wiring to be installed. Refer to Appendix D for Microgrid Site Plan design drawing developed by R&W Engineers in collaboration with PAE for the Chiller Plant Upgrade scope of work. 3.2 Distributed Energy Resources (DERs) NATURAL GAS GENERATOR The city is in the process of upgrading the generator from a 50 kW natural gas genset to a 500 kW natural gas genset. The upsized generator will provide power to both the emergency power ATS (ATS-E) as part of the Emergency Power Supply System (EPSS) and to the new 4RDP-0 switchboard for optional standby backup of the entire facility load. The generator will be controlled by both the microgrid controller and ATS-E in a failsafe emergency situation if the microgrid control system is unavailable during a utility outage. The generator will be dispatched by the microgrid control system utilizing a "cycle-charging" dispatch strategy. _ i June 9, 2023 PHOTOVOLTAIC SYSTEM The PV arrays on site will be divided into two main sub-system. The first system will be on the roof and will include 248 kW of DC nameplate capacity. The second system will consist of several carport arrays built over a significant portion of the library parking lot and will account for the other 259 kW of DC nameplate capacity for a total system size of 507 kW. The full PV system report can be found in Appendix A. BATTERY ENERGY STORAGE SYSTEM (BESS) The BESS will be equipped with a grid following and grid forming inverter and with power and energy ratings as determined by PAE for off grid resiliency. The battery inverter rating will be 1.0MW and coupled to a 2.7 MWh battery that will provide for full load backup for several hours in the event of a grid outage. Resiliency duration will be extended by the microgrid control system via selective utilization of PV and generator capacities with the system prioritizing PV energy when available during daylight hours. The full Microgrid Resiliency Report can be found in Appendix B. 3.3 Microgrid Control System PAE worked with city staff to determine which parts of the library load could be integrated with the building's microgrid controller and which could not. It was determined that the buildings mechanical and HVAC equipment which is currently controlled by the BAS can be integrated into the microgrid controller. As well, the lighting control system can be integrated although the system will need to be upgraded as the current control systems are too old to be integrated with the available microgrid controllers. The rest of the library load will need to be shed manually through either turning off or unplugging equipment at the receptacle, turning off circuit breakers in the branch panels, or through changes in human behavior like not turning on extra lights or not plugging in large receptacle loads during an outage event. The microgrid control system will be provided to manage or control the following aspects of facility operation and grid interactivity. 1. Resilient Operation: a. BAS - the buildings automated HVAC and mechanical equipment control system b. Lighting Control - integration will require a lighting control system upgrade. c. DER Dispatch- ensures the sum total of power from DERs equals the load needed with the goal of ensuring the highest level of renewable energy possible when in islanded mode. 2. Grid Connected Operation: a. PGE BESS dispatch - serves as a point of interface with PGE's GenOnSys for remote utility control of the BESS when grid connected. b. Grid energy cost optimization - taking advantage of available renewable energy (PV) during peak usage and peak rate windows. It is important to note that the proposed microgrid design is an open transition microgrid which means there will be a short duration interruption of power during loss of utility power. This approach to system design is less complex and less costly than a closed transition scheme. The microgrid system is not a UPS system for the building and as such any existing UPS systems will have to be maintained to ensure that all the critical elements of the library load are not disrupted in the event of an outage. June 9, 2023 . At this time a complete in-depth control schematic and sequence of operations for construction has not been included. This level of control design will be completed in later stages of project development. 3.4 Grounding System The new microgrid switchboard 4RDP-0 will serve as the new service entrance equipment and will be the point of neutral to ground bonding within the facility. The existing neutral to ground bonding in the existing MDP-A switchboard will be disconnected and removed. The remainder of the facility grounding system is existing to remain as currently configured. Each electrical and telecom room currently has its own ground bar that will remain connected to the facility grounding electrode system. 3.5 Pathways and Raceways Microgrid scope of work will include new underground conduit and associated trenching work throughout the project site including the facility parking lot to support the installation of PV carports. New above grade conduits will be included to integrate the rooftop PV system. Conduit provisions installed in the chiller plant and generator upgrade scope of work will be leveraged for deployment of the microgrid system. PAE has coordinated with R&W engineers to ensure adequate spare conduits have been provided in prior phases of work. June 9, 2023 �sss Appendix A - PV Report >A 0 >, I_ 4_.

The project is located at the Tigard Library 13500 SW Hall Blvd, Tigard, OR 97223. The City of Tigard's goal for this project is to help meet their carbon neutral by 2050 goal, reduced electrical bills and to use the library as an emergency operations center in case of emergencies. This ETO Solar Development Assistance report is informed through the PAE Engineering Tigard Microgrid Feasibility Study. The PAE feasibility study was completed in June of 2023 and provides the basis of design for the BESS system. Additionally, this Solar Development Assistance report was informed through satellite imagery, an on-site visit and preliminary structural engineering. The estimated annual energy production and Total Solar Resource Fraction (TSRF)was conducted through industry- leading solar production software, Helioscope. The findings of this report indicated no major issues that would prohibit the City of Tigard from installing a solar PV system and BESS at the library building.The City intends to apply for multiple grants in 2024 and hopes to start construction in 2025.

The BESS system is designed to use available PV power during peak usage and rates times. This will reduce the peak demand charges on the owner's electric bill as well as ensure the use of renewables as often as possible. Additionally, the BESS and solar PV system is sized to provide emergency power for the emergency operation center within the library for 7 days. The owner intends to participate in the PGE Schedule 200 program. This program will allow the utility to use the BESS in grid demand response applications. PGE will contribute $39.50 per nominated kW for ancillary services and $82.40 per nominated kW for demand response and ancillary services. There has not been confirmation with PGE on what the nominated kW rating for this project will be. Tigard Microgrid Project Battery manufacturer Current Energy ELM Battery kW 1,500kW Battery kWh 2,700kWh Microgrid controller ELM Field Sight Solar assessment report Battery Equipment Warranties Manufacturer Warranty length Battery Current Energy ELM 2-year material and workmanship 5-year parts Energy consumption The utility, PGE, provided 15 min interval data for the 2022 calendar year. The data shows the library building has an average electrical demand of 134kW. The summer months show an increase in electrical demand due to HVAC cooling loads. Overall, the building consumes 823,529kWh of electricity and 300,400kWh of natural gas per year. 3 c la) tow Hour of the Year Historic PGE meter data at 15 minute intervals for the 2022 calendar year—Tigard Microgrid Feasibility Study,PAE Customer Microgrid Benefits The benefits of the microgrid to the customer includes peak load shedding and resiliency for the building to act as an emergency operations center. The BESS has the ability to provide power to the building in instances of high energy demand. The library's electrical bill is based on PGE's schedule 83 which includes a number of charges that will be reduced by the BESS. These charges include on-peak usage, generation demand, on-peak demand, and transmission charge. During an emergency event a portion of the building will operate as an emergency operations center. The battery, PV system and backup generator are designed to provide power for seven days. Additionally, the BESS microgrid controller will integrate the solar PV system and backup generator. Solar assessment report Grid Microgrid Benefits The microgrid system is designed to provide benefits to the grid as well as to the customer. The grid benefits include participation in the PGE's Schedule 200. As a part of Schedule 200, the BESS will provide grid stabilization and support services to the utility. The battery has the additional capability to provide grid services through peak shaving, demand response, and time of use shift. Shade Analysis The library's site is surrounded by trees both on the property and adjacent to the property. The arrays located on the building have minimal shading outside of three trees located at the southwest corner. These trees combined with a slightly lower roof height reduce the western most roof array's production slightly. The two other arrays on the roof of the building have no shading concerns.The average TSRF for the roof top arrays is 82.1%. The five carports located to the south of the building have variable shading concerns.All five carports have some shading from trees with the three south facing carports having the least shading concerns. The two east facing carports have the most shading concerns due to trees on the southern end of the carports.Additionally, the western most carport has a series of trees due west which will block a fair amount of afternoon and evening sun. The average TSRF for the carport arrays is 81.3%. However, the western most carport has a TSRF of 65%. Overall, the site is a good location for solar. We recommend the City implement a strategic tree trimming plan to ensure the solar arrays do not become more shaded over time. Structural Considerations and Roof Age Our analysis of the building did not indicate any structural concerns for the ballasted rooftop building. The building is relatively new, constructed in 2004. Additionally, the owners intend to replace the roof before the solar installation. Preliminary engineering for the dual tilt ballasted racking system shows the system will have a 2.67PSF load. Furthermore, the preliminary engineering shows (10) mechanical attachments will be required. These attachments are for seismic purposes, but the number and location can be refined with a full engineering review. Cost Estimate Range This estimate includes all engineering, permits, equipment procurement, and installation costs required for a turnkey system. The lower end of the costs signifies what the installation of this system would cost today. The higher end estimates what this project could cost in one to two years. This microgrid project is fairly complex allowing plenty of areas for costs to change over time. The costs for trade exposed components such as steel and modules will likely see the most change. Additionally, the BESS market is still evolving. Battery costs have been trending down, but the market as a whole is still volatile. For planning and grant application purposes, the City should assume costs will increase over time similar to other construction projects. Low estimate High estimate Project cost/watt(including the cost of $7.27/watt $8.10/watt storage) Project cost $3,563,210 $3,919,531 Solar assessment report Financial Summary Our estimated costs for the PV system is$1,688,510. This PV price includes the carports, trenching, PV related wiring conduit and PV equipment. Our estimated cost for the battery system is $1,874,700. This battery cost includes the battery, isolation transformer, microgrid controller, control equipment, service gear and all battery related wiring and conduit. The total project cost, if installed today is $3,563,210. However, the owners intend to apply for several grants as well as installing a new roof and conducting HVAC upgrades which will extend the project time frame.Assuming a 10% increase in costs to cover any changes in material or labors costs before installation may be prudent. Additional Funding The City of Tigard intends to apply for multiple grants including the FEMA/BRIC, Hazard Mitigation Projects grant. This FEMA grant is meant to help cost effective projects which are designed to increase resilience and public safety. The City will also apply for the Oregon Department of Energy Community Renewable Energy Grant Program. The OR Department of Energy Grant is meant to provide funding for community renewable energy and energy resiliency projects. The Oregon Department of Energy also has a Solar+ Storage rebate for low-income services providers that the city plans to apply for. In addition, the City intends to work with the electric utility, PGE,for funding through the Schedule 200 program and apply for funding from the PGE Renewable Development Fund. Finally, ETO has agreed to provide an exception for this project. Allowing the city to receive a $15,000 installation incentive. Payback Using a simple payback method, it is estimated this project will pay for itself in year 24. The average annual electrical bill savings during this time period is $101,788.This financial module includes the costs for installing the PV system and BESS at today's price as well as a 30% IRA direct payment on year 1 and the $18,000 ETO installation incentive. It also includes a$72,500 cost for component replacement in year 15. Additional annual or semi-annual O&M costs have not been included at this time. If the city is awarded the Oregon Department of Energy Community Renewable Energy Grant and the Oregon Department of Energy Solar+ Storage rebate they could see an additional $1,045,000 in funding. This additional funding would bring the payback down to year 17. The FEMA/BRIC, Hazard Mitigation grant and the PGE Renewable Development Fund grant may cover up to 75% or up to 85% of eligible costs respectfully. It should be noted that several of these grants are competitive, and each grant has its own eligibility requirements as well as eligible installation costs. For example, one grant may cover the solar installation but not the costs for the battery system.Another example would be one grant may cover the solar installation but not the costs of the carport steel structures. It will be important for the city to thoroughly understand each of the grant requirements to maximize their success.A final note, this financial model does not include PGE Schedule 200 payments for grid services as these funding and payment services have not been confirmed. Overall, this project will be more financially successful with the additional funding sources. Permitting, Zoning, and Interconnection There are no permitting or zoning concerns for this project. The electrical interconnection is somewhat complicated with the significant amount of new electrical equipment that will be needed for the PV and BESS. The point of interconnection will also be somewhat difficult as the single line calls for an interconnection at existing underground conductors between the utility transformer and MDS. A handhold or vault will need to be installed for this interconnection plan. Overall, nothing has been identified that would prohibit this project from proceeding. Solar assessment report Additional Findings The clerestory located on the main roof of the building is tilted slightly to the north and currently has standing metal seam roofing. Though not ideal for solar production, the tilt to the north will be mostly mitigated by the east-west racking system. This roof section will also be converted to a membrane roof matching the rest of the building's roof surfaces. Next Steps The City is very motivated to see this microgrid project through. They have outlined the following steps to keep the project progressing: a City Council Workshop on January 16th, a Targeted Engagement with potential partners in December through March and submitting grant applications in spring of 2024. The City plans to start construction in 2025 and have everything completed in 2027. Based on the information gathered for this SDA, the City of Tigard's plan is very reasonable and most likely will result in a successful project.
