The Tanana River Test Site was established by the Alaska Hydrokinetic Energy Research Center (AHERC) and is now part of PMEC. Many functions can be performed at TRTS, including testing marine hydrokinetic (MHK) power-generating devices and measuring river environmental characteristics.

Permitting Status

All required permits are secured for TRTS, and mandatory baseline fish stock studies have been completed. Placement of turbines in river is subject to final regulatory review.

Device Accommodation

TRTS is available for testing hydrokinetic devices and infrastructure between May and September each year. The site’s anchored mooring system, located mid-channel, supports a floating platform able to secure a load up to 50,000 pounds.

Testing Capabilities

TRTS is equipped with environmental monitoring techniques during testing season. Additionally, NNMREC experts at UAF are available to carry out or assist with hydrological and environmental measurements, including those of mean flow, turbulent fluctuations, bathymetric surveys, fisheries interaction monitoring, and device power performance. NNMREC experts at UAF are also available to analyze data products derived from TRTS measurements, conduct hydrodynamic modeling, model debris interaction with MHK infrastructure, work with customers to develop debris tolerant designs, or review design and installation strategies for remote areas. Demonstrated technology to divert surface woody debris – a major impediment of operating devices in Alaska – is available to all users; a prototype for protecting devices from subsurface debris is in development.

Location Notes

Potential deployment locations for hydrokinetic power-generating devices have been identified based on river velocity, bathymetry, sediment transport, hydro-dynamics, power density and turbulence. Tenana River currents average 3 m/s.
