The U. S. Department of Energy (DOE) issued an environmental assessment (EA) for Northwest Arctic Borough High Penetration Solar and Battery Energy Project (DOE/EA-2302), which assesses the potential environmental impacts of DOE's financial assistance award under the "Energy Improvements in Rural or Remote Areas Program" and the Clean Energy Technology Development on Tribal Lands funding opportunities, OCED-FOA-0003045, OCED-FOA-0002970, and OIE-FOA-0002975. The Project and award would assist with deploying and integrating high-penetration solar Photovoltaic (PV) and battery energy storage systems (BESS) into the existing microgrid in the remote tribal community of Ambler, Alaska (AK) currently relying on diesel for 100 percent of their electrical production.
