UAF, Electric Utility Collaborate to Overhaul Kotzebue Energy Monitoring System

Kotzebue’s electric utility will install advanced electricity meters next year with help from the University of 91��Ƶ Fairbanks.

The new platform will allow researchers and utility managers to better understand the community’s electric use.

A $500,000 grant from the Office of Naval Research to 91��Ƶ Center for Energy and Power will fund the yearlong project. It will begin in February 2022. The Kotzebue Electric Association will build and install the system.

Kotzebue, a longtime ACEP partner on energy research projects, has integrated wind power, a solar array and lithium-ion batteries into its electricity grid. Collecting better information about those components could help the Northwest 91��Ƶ community fine-tune its blend of energy sources.

“This will be useful to Kotzebue and to the entire research community,” said Mariko Shirazi, the University of 91��Ƶ President’s Professor in Energy and a member of the ACEP research team. “Kotzebue has been a pioneer in integrating renewable energy since the late 1990s, and they’ve continued to push the envelope with technologies as they mature.”

KEA runs a diesel generator to regulate voltage and frequency as renewable sources fluctuate. The new generation and transmission meters will help evaluate how more renewable energy could be added to the KEA grid while maintaining high reliability and power quality. The ultimate goal is to operate the Kotzebue grid without a diesel generator when enough renewable power and energy storage are available.

“This gives us the measuring and analysis platform to move forward using less and less diesel fuel,” said KEA project manager Matt Bergan. “We are looking to utilize renewables to heat homes and provide electricity, and this gives us the platform to track that through the years.”

Kotzebue residential and commercial electric customers will also get more detailed pictures of their electricity use. The new meters will provide data at 15-minute intervals instead of the daily or, in some cases, monthly intervals used by current meters.

The new customer-side meters could also allow KEA to charge different rates for electricity to encourage use during periods of less demand. That could further reduce diesel consumption.

“We are looking forward to continuing our mutually beneficial research partnership with KEA,” said Dominique Pride, a research assistant professor at ACEP and the UAF lead on the project. “The new metering platform provides a tool that can help further reduce diesel consumption in Kotzebue and will also facilitate new research and educational opportunities.”
