What happens to the cable after the project is finished in 20 years?

Whenever the project is over, as part of decommissioning, the turbines will be removed. The cable could remain if Monhegan or some other party sought and received regulatory approvals to use it. Typically the design life of a cable is meant to coincide with the turbine life which is typically 20+ years, depending on the manufacturer’s warranty and actual wear.

A cable failure is unlikely to happen, but if it did, it is MAV’s responsibility to have it repaired. Annual inspection and electronic fault monitoring provide indications of damage and wear. Circuit breakers and GFIs shut off power if a short or fault is detected.
