Seward's Mount Marathon hydro plant is making power again after a rehab

by Cale Green · draft by Walter AlaskaNews(13h ago)
2 min readSeward, Alaska

Seward's small hydroelectric plant at the foot of the Mount Marathon race trail is generating electricity again, and the city is holding a grand opening there Wednesday.

The Mount Marathon Hydroelectric Plant "is officially operational" and "once again generating electricity for the Seward community," the city's electric department told the City Council in a report for its Oct. 26 meeting.

The rehabilitation upgraded the plant's infrastructure, mechanical equipment and control systems, and getting it running again helps Seward rely less on purchased power, the department said. The city buys power from Chugach Electric Association. The department hasn't said whether the plant will change electric rates.

About Energy

Energy in Alaska takes in the electric utilities, power plants, fuels and transmission lines that keep homes and businesses running. It ranges from the Railbelt grid of Southcentral and the Interior to village systems that run on diesel, and from hydropower to natural gas from Cook Inlet.

Recurring questions concern the cost of heating oil, diesel and gas, whether Railbelt utilities can generate enough power through winter, and how to add supply through the Bradley Lake hydro expansion, transmission lines and the Alaska LNG project. ENSTAR gas rate cases and Golden Valley Electric's thin generation reserves are among the utility questions that return. Rural communities seek heating assistance and ways to cut diesel use.

State bodies such as the Alaska Energy Authority and AIDEA lend to and invest in energy projects, including nuclear and geothermal ventures. Energy connects to the oil and gas industry, to utility rates and to renewables such as solar, tidal and geothermal power.
