The U.S. Department of Energy plans to provide up to $150 million in Defense Production Act funding for the Beluga-Healy Transmission Project, advancing a planned $418 million investment in Alaska’s power grid.
The Alaska Energy Authority is developing the project, which calls for about 223 miles of new high-voltage transmission between Beluga in Southcentral Alaska and Healy in the Interior.
The project would create a second high-voltage connection between the two regions. Once completed, the additional transmission route would give grid operators another path to move electricity between Alaska’s largest population centers and major military installations.
DOE said the project could strengthen grid reliability and lower electricity costs for communities representing about 75% of Alaska’s population.
Alaska plans second high-voltage transmission connection
The Beluga-Healy project would expand the transmission network serving the Railbelt, Alaska’s main population and electricity-demand corridor.
The new line would connect the Beluga and Healy areas and provide additional capacity between Southcentral and Interior Alaska. The project is intended to reduce reliance on the existing transmission connection and improve the grid’s ability to move power between regions.
AEA has included the Beluga-Healy connection in broader plans to modernize and strengthen the Railbelt transmission system.
The current federal announcement advances the project through a proposed federal funding commitment rather than marking the start of construction.
DOE targets transmission infrastructure with DPA funding
DOE said it intends to use up to $150 million from the Defense Production Act to support the transmission project.
The federal funding would be combined with about $268 million in non-federal funding, bringing the planned investment to approximately $418 million.
DOE’s action follows a presidential determination identifying transmission lines and conductors, substations, and power-control and protection equipment as essential to national defense.
The department said the transmission investment would support infrastructure needed for national security while strengthening Alaska’s electric grid.
Project could support military and resource development
The additional transmission connection would serve communities across the Railbelt while improving power access to areas with major military installations.
DOE also identified growing electricity needs associated with resource development as a factor in Alaska’s future power demand.
A stronger transmission network could give utilities more flexibility to move available generation across the system as demand changes.
The project could also support greater integration of future generation resources by increasing transmission capacity between regions.
Construction investment reaches $418 million
The project currently carries a preliminary total investment estimate of about $418 million.
Of that amount, DOE plans to provide up to $150 million through DPA funding, while approximately $268 million would come from non-federal sources.
The proposed transmission line would span about 223 miles between Beluga and Healy.
The federal funding announcement does not mean the full project cost has been federally funded. The remaining investment would require the planned non-federal funding and continued project development.
The Alaska Energy Authority is leading development of the Beluga-Healy Transmission Project in coordination with utilities and organizations involved in the Railbelt power system. Chugach Electric Association, Golden Valley Electric Association, Homer Electric Association, Matanuska Electric Association and Seward Electric Association participate in the region’s transmission planning structure, while the Railbelt Reliability Council also has a role in regional grid coordination. The U.S. Department of Energy is providing the federal funding support announced for the project.
The federal funding also reflects the administration’s view that Alaska’s transmission network has growing national-security importance. Energy Secretary Chris Wright said the project would strengthen grid reliability and help lower electricity costs while supporting the expansion of military operations in Alaska. He also linked the investment to mining and other resource development.
“Supporting improvements to Alaska’s transmission infrastructure with Defense Production Act funds reflects the Trump Administration’s commitment to strengthening national security, improving grid reliability, and lowering electricity costs,” Wright said. He added that briefings from the Alaska Energy Authority and Alaska Command reinforced the need to expand the state’s energy infrastructure.
Beluga-Healy project moves toward development
The latest DOE action marks a major funding milestone for a transmission project that has appeared in Alaska’s longer-term Railbelt grid planning.
The next steps will include advancing project development, funding arrangements and the work required to move the transmission connection toward construction.
The Alaska transmission investment is part of a broader U.S. Department of Energy effort to strengthen the power system as electricity demand grows. DOE has also issued a conditional loan commitment of up to $4.2 billion to support Vistra’s nuclear uprates at three plants in Ohio and Pennsylvania, a program expected to add 433 MW of nuclear capacity while preserving nearly 4 GW of existing generation.
If completed, the Beluga-Healy line would provide a second high-voltage pathway between Southcentral and Interior Alaska and add another layer of reliability to the Railbelt system.
