U.S. Department of Energy Awards Tribal Energy Infrastructure Grants to Three Alaskan Communities

Congratulations to the Igiugig Village Council, Nuvista Kwethluk Energy Storage, and Togiak Natives, Ltd for being selected as tribal energy infrastructure funding recipients by the U.S. Department of Energy. Out of just fourteen selected projects, these three are all from Alaskan communities.

  1. Igiugig Village Council (IVC), Igiugig, AK – $3,033,584 ($1,516,792 DOE funds, $1,516,792 cost share) – IVC will acquire and install a second 35-kW marine renewable energy device in the Kvichak River, along with smart microgrid electronics and energy storage, to provide autonomous operation of the microgrid to power all Village facilities for sustainable energy supply and resilient operations. Based on IVC’s existing generation at 12.14 kilowatt-hours (kWh) per gallon of diesel, the corresponding annual fuel displacement of the power from this installation will be approximately 11,000 gallons per year. The anticipated avoided cost of diesel generation is between $68,000 and $88,000 per year for 20 years.
  2. Nuvista Kwethluk Energy Storage, Anchorage, AK – $892,562 ($446,281 DOE funds, $446,281 cost share) – A joint venture between Kwethluk, Inc., the Organized Village of Kwethluk, and Nuvista Light and Electric Cooperative, Inc., this project will install a 500-kW/670-kWh battery energy storage system that will be integrated into the Kwethluk wind-diesel system. When fully charged, the system will be able to meet the peak load of the entire community at a rate of more than 500 kW for more than 1 hour or over 2.5 hours of restricted emergency power at the current average community load of 180 kW. Estimated annual savings from the battery are approximately $68,000, with a potential lifetime value of $1,170,000.
  3. Togiak Natives Limited, Togiak, AK – $1,276,106 ($638,053 DOE funds, $638,053 cost share) – This heat recovery project will use excess heat from the existing power plant to heat three end-user tribal community buildings. Currently these buildings are heated by oil boilers, which use a total 13,691 gallons of diesel heating oil per year. The heat recovery system is expected to offset 100% of the heating oil required by the end-user buildings, thereby saving an estimated $77,080 per year or over $2.3 million over the life of the project.
