Submarine cable plus photovoltaic support

How much does a submarine cable project cost?

For a utilization time of 5000 h/year and a 1.79% power loss rate, the total investment of the project is approximately $ 1.2 billion USD. Besides the cost of 60 km overheard transmission on land and two conversation stations on the ends, the 200 km submarine cable investment is approximately 500 million USD.

Will Sun Cable develop a giant solar PV & battery energy storage complex?

Singapore-based Sun Cable is seeking to develop a giant solar PV and battery energy storage complex on a 12,000-hectare site in the Northern Territory’s (NT) Barkly region. The project includes a 17-20 GW solar farm and between 36 GWh and 42 GWh of energy storage.

How much does a subsea cable project cost?

The overall subsea cable project cost has been estimated to be approximately $6 billion. This interconnector cost estimate highlights that the project cost is mainly driven by the HVDC cable supply cost.

What is the production capacity of HV submarine cable manufacturers?

According to an assessment performed by Europacable , the combined production capacity of Europe-based HV submarine cable manufacturers (extruded or mass impregnated, HVDC or HVAC) is in the order of 5000 km per annum.

Why do we need to reduce the cost of HVDC submarine cable?

As the cost of submarine cable is 5 ~ 10 times higher than that of the overhead line, the project investment need to be decreased to a level within the economical carrying capacity to guarantee extensive applicability of the HVDC submarine cable technology.

What is the capacity of UHV submarine cable engineering in North Africa?

The total length is 4000 km, while the total capacity is 50 GW. The proportion of the UHV submarine cable engineering reaches 40%. The North Africa region is rich in solar and wind power resources, and can effectively compensate for the power shortage in the energy transformation process in Europe.
