Alaska Energy Planners Design 50-Year Systems Using 2008 Weather Data

Alaska's energy infrastructure planners are designing systems meant to last 50 to 100 years using historical weather data from 2008, which no longer reflects current conditions. Western Alaska has seen repeated hundred-year storms, but federal agencies lack enough historical data to confirm the designation.

"We are using historical data and historical baselines which no longer match the reality that we're planning for," said Leasi Vanessa Lee Raymond, Deputy Director for Strategic Initiatives at the Alaska Center for Energy and Power.

When Ex-Typhoon Halong struck in fall 2025, Alaska Village Electric Cooperative shifted priorities for about a month to respond to 23 communities where power distribution systems failed. AVEC serves 58 communities with 46 diesel power plants, burning over 9 million gallons of diesel fuel annually.

Emergency Response Costs Fall on Utilities

William Stamm, President and CEO of AVEC, described the emergency response in Noatak, where permafrost degradation and river erosion threatened the airport, fuel storage, power plant, and water supply. AVEC moved a standby generator to the site in August 2024 when the braided river upstream shifted flow patterns and began carving away land quickly.

The cooperative has spent two years coordinating with the Department of Transportation, EPA, the Denali Commission, and Alaska Native Tribal Health Consortium to relocate the tank farm near a new airport two miles from town. AVEC has borne most emergency costs itself, including $100,000 to rent a Hercules aircraft to fly in the generator.

Funding Remains Uncertain

Jocelyn Fenton, Director of Programs for the Denali Commission, said consistent funding for environmental threats to infrastructure remains elusive, making planning and implementation work difficult. The Denali Commission's 2019 statewide threat assessment ranked communities by erosion, flooding, and permafrost risk; a 2026 update will add wildfire, volcano, earthquake, and tsunami hazards.

The commission received $100 million from the EPA last year for bulk fuel infrastructure upgrades in 10 communities. The congressional delegation is asking what it would look like if Alaska could redirect $80 million annually from existing federal programs to protect infrastructure.

Stamm identified workforce development as ranking alongside funding as a top need. "If you have talented people that know how to take care of things, then you have less outages," Stamm said.
