Planning equals success for 2016 Cedar Rapids flooding

The Cedar River normally flows through Cedar Rapids at a depth of four to seven feet. In late September 2016, very heavy rains sent a flood of water downstream. The forecast called for the river to crest between 24 and 25 feet. While several feet lower than the flood of 2008, our customers, employees and facilities were once again in the path of rising water and potential harm.

Our employees jumped into action over the course of the event. They constructed flood walls and worked extra hours in temporary locations to keep our customers connected, safe and informed. Success was due to the planning, problem-solving and cohesiveness of our crisis management and restoration emergency operations teams. These teams ensured business continuity while protecting buildings, securing critical infrastructure and keeping people out of harm’s way during the flood.

To help areas that experienced water damage, we increased energy efficiency rebates by 50% for flood-affected customers across 21 counties through the end of 2016. Our goal was to offset the financial impact of replacing equipment like furnaces, air conditioners, water heaters, heat pumps and whole-house fans.

Specialized sand-filled barriers were installed for protection along the Cedar River. Excess unused barriers were later sent to help with flooding in Idaho and Washington.

Strengthening the power grid

The U.S. power grid – a combination of poles, wires, substations and other equipment – is aging. With our customers in mind, we have developed a long-term plan to build smarter energy infrastructure and enhance the resiliency of our electrical distribution system from natural disasters and extreme weather.

Improving reliability: In the last five years, we’ve been able to reduce the length of outages by nearly 30%. One way we’re making the power grid more reliable and secure is by putting more equipment underground. We’re also installing stronger poles, larger wires and more robust equipment.

Reduced costs with higher voltage lines: We’re upgrading our lines, transformers and substations with 25-kilovolt equipment, which can carry about four times as much power as today’s system. Because power travels further at higher voltage, it requires fewer substations. This saves money for our customers.

Integration with customers who make their own power: The power grid was originally built for a one-way flow of energy – from generating stations to customers. Today, utility companies aren’t the only ones producing power. Customers with solar panels or other systems are producers, too. We’re optimizing our grid to enable the new two-way flow of energy and information.

Electric vehicle use offers cool benefits

There are some cool benefits to owning an electric vehicle (EV). You don’t have to worry about gas money, you can cash in on rebates and you shrink your environmental footprint. We have been working on a number of initiatives to encourage the use of EVs throughout our service area. Here are a few examples:

  • Our Bright Ideas program provided a $50,000 grant to the Renewable Energy Committee for Burlington, Iowa, and the dollars were used to purchase fast-charging stations in 2016.
  • As part of our workplace charger rebate program, we provided $1,500 to Beloit Hospital to support installation of its first electric car charging station in early 2017.
  • Ride, Drive and Learn events were held to showcase electric vehicles from local dealerships, charging stations and informational exhibits.
  • We continue to offer up to a $500 rebate for the purchase and installation of a Level 2 home charging station.
