Upgrade Paths

Thank you for your patience as we upgrade our underground transmission cables.

As part of the transmission upgrade project, BELCO is replacing 40% of its current underground transmission cables that are over 50 years old. Nearly 25% of our cables have served Bermuda for over 60 years! These cables and other transmission and distribution assets are well beyond their useful lifespans, causing a higher number of faults, system vulnerability and higher maintenance costs.

Getting our grid ready for large-scale renewables


At this point in time, the grid is limited in its capacity to support large-scale generation from renewable resources. Our old cables and network were designed for central generation; they were not designed to accommodate generation from sources distributed across the network. The transmission cables serve as the backbone of the grid; thus their replacement represents a critical step in moving Bermuda towards its energy future.

TD&R upgrade construction project

The new cables are being installed in multi-service duct banks that will eliminate the need to dig up the roads for cable replacement in the foreseeable future.

Working closely with Works & Engineering and other utilities, the construction phase has been designed to complement Government’s future water and sewage.
