Con Edison implemented storm hardening initiatives following Superstorm Sandy to increase the resiliency of its electric system. Immediate hardening was completed by June 2013 and included flood barriers, pumps, and sealing equipment at 9 substations and 3 generating stations. A $1 billion, multi-year storm hardening program was proposed to continue hardening efforts through 2017. This includes raising critical equipment, backup generators, robust walls and doors, and new control systems to protect against flooding up to FEMA's 100-year flood level plus 3 feet. Con Edison collaborated with regulators and stakeholders to review risks and justify storm hardening projects.
