Video: OPPD persevered amid historic flooding

2019 Nebraska floods

The historic March 2019 Nebraska floods that struck parts of the OPPD service territory impacted the utility’s power plants and other infrastructure.

A quick response, and activating the business continuity plan, led to a minimal impact on service. As work enters its second week, OPPD is focusing on specific infrastructure needs at the Nebraska City Station generation plant and substations around the service territory.

Across Nebraska, nearly two-thirds of the state’s 93 counties had declared emergencies due to flooding and/or blizzard conditions.

Weekend warriors

Members of OPPD’s business continuity team and personnel from all departments worked around the clock over the weekend to ensure infrastructure was protected and safe from encroaching floodwaters.

And their passion to serve customers never waned.

A 5-person OPPD crew found themselves stranded in the Fremont area and unable to cross area rivers to return home. But they kept busy answering trouble calls unreachable due to flooded roads, sleeping in their truck when they could. They stayed in the flooded area for several days until a road opened and they could return home to their families.

Back in Omaha, the business continuity team scrambled to get them out over the weekend, but the crew had only one response: “But who will be here to answer the trouble calls?”

They were willing to stay and do all they could to help in Fremont, which was almost entirely isolated from outside traffic and supplies over the weekend.

Nebraska City Station

The new week meant new challenges for OPPD infrastructure, including shoring up and monitoring a levee near Nebraska City Station (NCS) and ensuring the stability of substations.

There were concerns that floodwaters would overtop the levee that helps protect NCS. OPPD is monitoring a lower-lying area on the levee, about one mile south of the plant, even as waters stabilize and begin to recede in coming days. The levee stretches along the plant’s boundaries and buffers it from the river. OPPD also used aerial inspections to monitor the levee.

Work at NCS continued throughout the night Monday to erect a barrier to protect the access road to the plant. Personnel also filled sandbags through the night Friday to Saturday morning to protect equipment.

“Our personnel have made quick, thoughtful decisions in recent days to protect OPPD’s infrastructure and facilities,” said Mary Fisher, vice president of Energy Production and Nuclear Decommissiong at OPPD. “But most importantly, they have done so safely and with a passion to serve OPPD’s customers no matter the situation.”

OPPD made the decision to power down the plant’s second unit the night of March 15 after water levels rose. Unit 1 was already in a planned maintenance outage before the flooding. The utility also put that outage on hold Friday. All staff then transitioned to refocus on protecting the plant.

OPPD President and CEO Tim Burke said even though both units at Nebraska City are not online, the utility is meeting customers’ power needs. OPPD also has several generating stations not located along the river to utilize.

“We will have enough power to serve our customers,” Burke said.

OPPD’s generation fleet has several peaking stations and units on reserve at North Omaha Station. The utility uses the units during periods of high load. The utility quickly called the units into action to serve customers over the weekend.

Substation infrastructure

Personnel worked tirelessly to protect several substations threatened by floodwaters to ensure the power stays on. Crews were managing and monitoring several substations throughout the service territory.

Crews took measures to pump water from facilities and protect them with sandbags and personnel from other areas of the utility’s Energy Delivery department relocated to substations locations to assist.

“Our team has managed through a changing and complex situation,” said John Buckley, director of Work Management at OPPD. “The tireless dedication has been impressive this past week. We are fighting the flood and we’re taking care of our regular business.”

Buckley also called out the work of employees in OPPD’s system operations departments. They ensure electricity is flowing correctly and efficiently as well as coordinating with generation on power flow.

“It’s all about teamwork,” he said.

Disconnecting flooded properties

As the waters recede, homeowners may be returning to their homes to assess the damage.

In areas under evacuation orders, OPPD works with local emergency management agencies to disconnect power to large areas of customers. Individual customers can also request a power disconnection if their home or property is flooded.

Re-establishing electrical service to flooded homes and businesses involves inspections and permits. OPPD urges customers to follow a specific process to restore electrical service to their properties.
