Chefornak is a remote community of 423 Yupik natives in Southwest Alaska. The Naterkaq Wind diesel system consists of three 95 kW wind turbines, 20 residential thermal stoves, and wind diesel systems controls, a power plant with 3 gensets and controls. The addition of the BESS system consisting of a 500kVA/677kWh Powerstore, shelter and controls will provide the community with resilience and fuel savings optimization of the wind resource. PROJECT SUMMARY The Chefornak Battery Energy Storage System(BESS) consists of the following components: • Hitachi Powerstore BESS rated at 500 KVA inverter with 677kWh of battery storage • Triodetic foundation for the Powerstore and battery shelter 16X32Ft • Steel master building 16x24 Ft with decking stairs hand rails. Insulation, • 500 kVA Isolation transformer • E + micro battery module software integration for the battery. PROJECT DESCRIPTION Naterkaq Light Plant (NLP) has completed a project design for the BESS integration. The BESS will be located on city land within 100 ft of the power plant to the West .The project will be owned and operated by the Naterkaq Light Plant (NLP) and the community of Chefornak. The Battery energy will be integrated into the NLP grid through an isolation transformer to the Power Plant Bus. The Battery shelter is a 16 x 24 ft building with 2 decks and stairs elevated 4 feet above grade with a triodetic foundation. This foundation is adjustable and can be moved if needed. The Shelter has been engineered for the site's wind and snow loading. The Shelter has insulation and venting for climate control. The Shelter is equipped with lights, receptacles and heater. The Powerstore cabinet is mounted to a skid with internal HVAC and fire suppression systems. It is rated for outdoor installations. Buried armored cable will connect the Powerstore BESS to the Power Plant Bus. The Chefornak BESS system design is based on similar installations in the neighboring communities of Kipnuk, Atmautluak and Tuntatuliak. The BESS System represents a scalable renewable energy integration backbone, which can be expanded through the addition of wind, solar and energy storage capacity leading to greater and greater diesel fuel displacements. 1 Naterkaq Light Plant BESS Project Implementation Plan Power Plant Controllers The BESS will be integrated with the existing diesel power plant control system using a specialized BESS Module for the E+ micro. There are 2 controllers / SCADA systems in Chefornak currently. The AEA control system will remain in the power plant and function as designed. The system monitors the power plant, gensets, auxillary systems to display on the SCADA for the operators. The IES E+ micro control is installed and controls the wind farm, load regulator boiler, and ETS stoves. This E+ micro will share data and some limited control over diesel on /off transitions with the AEA controller. This has been successfully done in other projects in Alaska for this purpose. The end control product over the system supports both AEA technicians and renewable contractor technicians to diagnose and trouble shoot remotely. In the event that one of the controllers fails there is some redundancy in controllers. The E+micro is a supervisory control hardware and software system, which is responsible for communications, metering, data collection and monitoring, and component integration and optimization. BESS Commissioning This integration process will require commissioning of the Powerstore utilizing Hitachi and Samsung technicians. The team of technicians will travel to the site for 5 days for the startup and commissioning of the equipment. They will be accompanied by IES personnel to assist with the travel, logistics and site control. This startup process includes full battery charge and discharge tests as well as confirming the power rating and power quality of the inverter's exported power. The battery management system (BMS) is checked by Samsung by remoting into the system. The battery modules are checked at the cell level for internally balancing on each of the 88 batteries in the bank. The next step is to ensure that BESS can be controlled remotely with Mod bus commands for the E+ micro controller. Power System Integration The integration of the commissioned BESS into the power system in Chefornak will take software changes, and testing to optimize the components in the system. The process can take a few months to watch the system as it works in various modes and how it operates. Initially the control technicians will be onsite for 7 to 10 days. The system includes, (1) load -controlled boiler (LRB) plumbed into the heat recovery loop of the power plant and (20) electric thermal storage units (ETS), which are distributed across the community, (3) 95 kW wind turbines, and (3) diesel gensets in the power plant, (1) BESS, and (2) Supervisory controllers. Naterkaq System Training To ensure the most effective training for Naterkaq technicians, training starts during the construction and continues during the commissioning and integration process. Training methods includes on-the-job training mixed while Contract technicians are in the Village, and specific manuals and training videos to be used during continued operations. In addition, the primary contractor, IES, is available remotely. K Naterkaq Light Plant BESS Project Implementation Plan Performance Measures The Battery system is currently driven only by the wind power, the wind resource was evaluated by experienced meteorologists to confirm the suitability of the resource. Wind resource evaluation indicates an outstanding wind resource with an average annual wind speed of 6.75 m/s and a wind power distribution well suited for the year -long capture of wind energy. The two primary project performance metrics are: • 600,000 kWh of wind energy displacing an estimated 39,000 gallons of diesel fuel annually. • 2600 hours of Diesels off / battery on the power plant. Displaced diesel data will be captured by the SCADA system at the powerhouse. This percentage is tracked and tallied monthly on the Chefornak powerhouse summary reports see attached appendices. Monthly PCE reports are submitted to the State of Alaska by Naterkaq Light Plant (NLP). These figures are reported annually to the State of Alaska in a report showing the community's energy usage and gallons of fuel used for power generation. The project goal is to displace 39,000 gallons annually. The second metric is diesel -off hours. This is the cumulated amount of time the wind turbines and the BESS are controlling the grid and the diesels are off line. Diesel -off is estimated to be 2600 hours annually. Project Schedule The estimated duration of the Chefornak BESS Project, from award to commissioning is 10-11 months. The project schedule is dependent on project start date, and alignment of shipping and construction windows. Since Chefornak is not accessible by road, all equipment and materials must be delivered by barge during the ice -free season or in the winter months with air freight or tractor and sled. The Powerstore and batteries were delivered to Chefornak in August 2023. The remaining materials for the project are either in Bethel, in storage or in route to Bethel. The materials will stay in a secured yard and in connexes in Bethel until the tractor and sled (winter barge) picks the freight up and delivers it to Chefornak over land. This land route is dependent on the frozen winter conditions for safe passage. It is anticipated that safe conditions will allow for travel in February. Once the materials are in place, construction can start. The construction will be conducted during the winter months of February through April, when there is sufficient daylight, and when the ground is sufficiently frozen to support heavy equipment. Once the BESS electrical installation is complete, the Powerstore commissioning can be started with system -wide commissioning to follow. The project schedule below outlines major tasks and proposed timelines for completion. 3 Naterkaq Light Plant BESS Project Implementation Plan Project Management Plan While experienced in utility operations and maintenance within the community of Chefornak, Naterkaq Light Plant (NLP) has contracted Intelligent Energy Systems, LLC (IES) for project design, project management and project support services.
