Looking at complex systems in this case, cities also encourages municipal developers to address multiple risks, rather than create a separate plan for each hazard, she said.
This process "helps cities prioritize and have an explanation of why they're investing in one thing versus another," she added. "It helps build consensus."
Electrical grid experts at Sandia bring resiliency to power supply
Ellis works with a Sandia team on infrastructure resilience to prevent the kind of damage suffered in New York and New Jersey after 2012's Superstorm Sandy.
Sandia researchers are using the labs' Energy Surety Design Methodology, which has a successful track record at military facilities, for two projects in New Jersey funded by the Department of Energy.
Sandia is working with the city of Hoboken, N.J., to assess and develop designs for improving the resiliency of the city's electrical grid after the storm.
Sandia also is working on a study with New Jersey's Transit Corporation, NJ TRANSIT, to provide a resilient energy supply system to trains running between New York and New Jersey during power disruptions.
Sandia is providing NJ TRANSIT with a design concept for a microgrid, which, if built, would be the largest microgrid by capacity and geographical footprint in the U.S., Ellis said. A microgrid is connected to a utility electrical grid, but can also operate as an "island" grid that self-sufficiently produces power when there is a disruption in the main grid.
The power system is being planned with resiliency in mind. For example, the generation plant and transmission and distribution lines will be protected from wind and storm surges, he said.
Resiliency requires planning ahead for disasters that might happen once every 50 years or more. That can cost millions of dollars up front, but can reduce a city's exp
