further clean energy advancements in American Samoa. Goals and visions overlap between ASREC and American Samoa governmental entities, which can now work together to revisit pre-COVID objectives and missions in the energy sector.. further clean energy advancements in American Samoa. Goals and visions overlap between ASREC and American Samoa governmental entities, which can now work together to revisit pre-COVID objectives and missions in the energy sector.. developed from an analysis of recent publications that include utility-scale storage costs. The suite of publications demonstrates wide variation in projected cost reductions for battery storage over time. Figure ES-1 shows the suite of projected cost reductions (on a normalized basis). Market trends indicate a continuing decrease in the cost of battery storage, making it an increasingly viable option for both grid and off-grid applications.. Though the battery pack is a significant cost portion, it is a minority of the cost of the battery system. The costs for a 4-hour utility-scale stand-alone battery are detailed in Figure 1. Figure 1. Cost details for utility-scale storage (4-hour duration, 240-megawatt hour [MWh] usable). Residents experienced consistent power rationing and outages, and key services like hospitals and schools hinged on infrequent fuel imports.[1] Now, the island runs on a completely renewable microgrid that meets 100% of residents’ energy needs through solar power and battery storage.
