OPPD News Release
Omaha Public Power District has taken another important step in its Power with Purpose project to add 400 to 600 megawatts (MW) of utility-scale solar generation and up to 600 MW of backup, modern natural gas to the utility’s generation portfolio.
The utility has selected nine Wärtsilä 18V50DF internal combustion engines (RICE) to power OPPD’s new Standing Bear Lake Station in Douglas County, one of two gas plants that will serve as backup to the coming solar generation. Like OPPD’s Turtle Creek Station going up in Sarpy County, Standing Bear Lake Station will be used as a peaking station, which means that the plant will run only as needed, per market conditions (estimated at less than 15% of the time).

Wärtsilä engines can later be converted to carbon neutral fuels to further enhance decarbonization. Wärtsilä has researched hydrogen as a fuel for 20 years and can currently use 15%-25% hydrogen blended with natural gas. Going forward Wärtsilä is developing the combustion process in its gas engines to enable their use with up to 100% hydrogen.

Growth spurs additions to OPPD’s system, by Jason Kuiper
While OPPD does bring on a few new circuits each year, OPPD planners are beginning to look at alternatives to adding new circuits. Non-traditional fixes such as batteries and solar power might be closer than people realize, [Mike Herzog, manager of Distribution Planning] said. “We are taking a closer look at what we call ‘non-wire’ solutions,” he said. “And those technologies could be fixes for adding more circuits. There are areas in our city that it would be very difficult and disruptive to put in a new circuit, like some of the main arteries in the city. So we are always looking ahead.”

AMERICAN PUBLIC POWER ASSOCIATION SERIES
Celebrating public power in America series – Part 2: Celebrating the Modern Public Power Utility
The American Public Power Association is pleased to present the second in-depth, three-part Public Power Current newsletter series to celebrate public power’s past, present, and future. Yesterday we described how local leaders began what would become the nation’s oldest continuously operated public power utility, in Butler, Missouri. Today, the Butler Electric Department is a modern utility: it owns Missouri’s first utility-scale solar farm, has emergency-only generators, a fully remodeled and upgraded power plant, and is studying the addition of wind power to help meet the needs of a growing town. Today we share how three public power utilities have adapted to changing times and local needs.
