Kootznahoo Inlet
LPS will install its in-current hydrokinetic equipment in an energetic tidal strait in SE Alaska, to power up an islanded Native American community currently powered by costly diesel fuel. Testing is being carried out under a current ARPA-e award. The proposed project would consist of the following new facilities: (1) a partially buoyant submersed tidal current energy converter with a 3-meter-diameter rotor tethered to an anchor post driven into the seabed in Kootznahoo inlet generating up to 300 kW; (2) a dual electric cable, each with a capacity of 13.2 kV, connecting to an on-land storage system; and (3) an on-land energy storage system in the City of Angoon consisting of individual lithium-ion battery cells. The Kootznahoo Inlet Tidal Power Project does not intend to directly connect to the Angoon electricity system.

Site Characteristics
Geographic characterization for the project location:
- Open Ocean: Main body of ocean, not enclosed or partially enclosed by land
- Coastal: Open water near the coast, spanning between land and shelf boundary
- Enclosed Bay: water that is partially surrounded by land, with a mouth open to larger water
