Alaska is an energy superpower with more untapped renewable resources than most countries. Yet its largest population, in the Anchorage area, faces a real risk of blackouts beginning in 2027 due to declining gas supply from the nearby Cook Inlet gas field, which is likely to force this historical major supplier of oil and gas to import LNG to keep its residents warm and keep the lights on. A key part of getting ahead of the crisis is addressing transmission dysfunction so severe that it turns 6-cent renewable electricity into 20-cent retail power due to ‘pancaking’ tariffs.

In this episode, we explore Alaska’s sole electricity transmission grid, which connects most of the major population centers along what is called the Railbelt. We learn about how Railbelt utilities are part of a system that’s overbuilt, unoptimized, unnecessarily expensive, and slow to change. For example, four rural electric cooperatives built more than $1 billion in unnecessary gas generation between 2012-2016 while knowing gas supplies were declining. Despite sitting atop an estimated 18 gigawatts of tidal energy potential in Cook Inlet alone, the four Railbelt cooperatives lack economic dispatch coordination, wasting tens of million annually through inefficient scheduling of gas-fired generation. The Railbelt utilities could transition away from their dependence on gas and toward the vast renewable resources surrounding them, but it would take a kind of political leadership that is currently lacking in the state. We dive into how the regulatory agencies could help Alaska transition to renewables, as well as why they haven’t done so thus far.

We also take a quick look at the future of Alaska’s famous oil pipeline, the Trans-Alaska Pipeline System (TAPS), and some of the expectations for nuclear power in the state.

This episode is the third and final part of our miniseries about the energy transition in Alaska.
