CTS cable solutions provide more efficient power delivery in onshore and offshore networks

Electricity Generation and the Grid

Since the company’s foundation in 2014, Enertechnos’s core activity has been and remains the development and adoption of a new form of cable for transmission and distribution networks, called Capacitive Transfer System (CTS).

Electrical energy needs to be transmitted and distributed (T&D) from the point of generation to the point of use in the most cost-effective way, taking into account the geographical, topographical and political barriers. By and large, electrical energy cannot be stored except on a very local and usually low-power basis (for example, using batteries).  As a result, electricity continuously flows between generation and consumers while creating heat losses inside power lines.

Benefits of CTS in Networks

According to the International Energy Agency (IEA), losses in grids resulted in around 1 gigatonne of carbon dioxide (Gt CO2) emissions in 2018. They estimate that reducing worldwide losses towards efficient levels of around 5% from as much as 18% in some regions today could reduce these emissions by over 400 Mt CO2.

Innovative CTS cable design can deliver power more efficiently while reducing losses and amount of copper used to deliver the same power as conventional cable.

By 2050 it is expected that the peak energy demand will double against 2020 levels. T&D losses in 2040 are equivalent to the entire forecast demand by the global fleet of electric vehicles (EVs) in that year.

Subsequent cable testing and modelling has shown that CTS not only can reduce losses by up to 47%, it can also provide more capacity per unit of conductor reducing cross section by up to 30%, assist with harmonic filtration and help to provide reactive support in grids.

CTS cable

Enertechnos has developed solutions for underground cable systems at voltage up to 150kV and delivering up to 400MVA, potentially reducing cable costs up to 30% per MVA delivered while reducing heat losses inside the cable.

The Future of CTS

We are developing subsea CTS designs to support ongoing growth in offshore networks connecting islands, renewable generation or oil & gas sites. High voltage application of CTS can allow delivert of offshore wind power over long distance by AC, avoiding expensive and challenging-to-maintain HVDC converters. Although at first CTS was developed for cable solutions it can be also adapted for overhead line applications.
