INNOVATION FOR A

MORE RESILIENT AMERICA

A national consortium advancing the science of extreme storm resilience

WHAT ’ S AT STA K E The convergence of expanding coastal populations, intensifying storms and escalating rebuilding costs is redefining risk across human safety, economic stability and national security.

Storms are changing – in some cases strengthening at unprecedented rates. Weather patterns are intensifying.

Hazards are compounding as wind, water and surge converge in ways that place escalating challenges on society.

When risk changes, science must do more than adapt.

IT MUST ADVANCE.

U N MATCHE D R E S EARC H CA PABI L IT Y The nation’s leading wind, wave and surge scientists and engineers have created a new scale of research. NICHE integrates environmental hazards with full-scale testing of structures and materials under realistic extreme conditions.

PHYSICAL EXPERIMENTS + computational modeling + field observations = more efficient research

When built, the testing capabilities and impact of NICHE will be unrivaled anywhere in the world.

NICHE REPRESENTS THE MOST AMBITIOUS LEAP FORWARD IN RESILIENCE SCIENCE IN A GENERATION.

When complete, it will be: • The world’s most powerful wind-water testing facility That is capable of: • Full-scale testing that more faithfully replicates real-world conditions and simulates the effects of natural hazards.

• 200 mph winds and 16-foot waves It will: • Include a digital twin that will enable stakeholders to experience tests in a fully immersive virtual simulation.

SITE REQUIREMENTS

Land • Overall constructed facility footprint is approximately 2000’ x 35’ not including clearances (debris), parking, staging, auxiliary buildings, water tanks, etc.

• Ideal clear footprint should be at least 3000’ x 600’ (41 acres contiguous) • 50 to 100 acres total reserved for future outbuildings and/or other expansion • Access to a pond for water source, storage and drainage highly desirable Electrical Power • 80 MW planned (may potentially increase leading up to PDR) • 13.8 kV assumed • Assumption that max wind and max wave will not be run simultaneously and that allowable loading schedules will be interlocked via a PLC • Wind System

• 20 fans @ 4,000 HP each (80,000 HP total) – 59 MC • Motors are 4 kV, 40 Hz motors • VFDs have 13.8 kV primary side, 4 kV secondary side

• Wave System

• 35 MW assumed load at max

• Pumping and Filtration

• ~5 MW assumed max load

• Current Flow

• ~15 MW assumed max load for 2 m/s current

• Other loads

• Capacity requirements TBD • Building typical loads (lighting, HVAC, offices, etc.)

• Data center • Cranes

Conventional testing can produce inaccurate results when scaling down low-rise buildings to investigate hazard impacts or miniaturizing sand particles to study beach erosion. TO SOLVE THESE PROBLEMS OF SCALING, NICHE IS BEING DESIGNED AS A FULL-SCALE FACILITY. U nmatche d Res e ar ch Cap a b ility
