2nd Malta-Sicily Cable Link
The project consists of a new approx. 122km long 225MW HVAC electrical cable interconnection through a submarine cable operating at 220kV between Malta (Maghtab) and Sicily (Ragusa) to be laid in parallel but at a safe distance to the existing HVAC cable link which was commissioned in 2015.
The project is part of Maltese Government’s future energy strategy in meeting the 2030 climate and energy targets and the longer-term decarbonisation objectives. It aims at diversifying the island’s energy sources and meet the projected increase in electricity demand from economic growth and electrification of the transport sector.
The 2nd cable link will also strengthen the electricity interconnectivity with the EU electricity network, allow for increased importation of electricity sourced from renewables, optimise the use of local power generation, whilst allowing the increase in local renewable energy sources through the enhancement of the grid stability and balancing of intermittent RES.
In June 2024, the project was successfully approved for funding under the 2021-2027 ERDF/CF/JTF Programme, specifically under Priority 2 ‘Promoting clean and fair energy transition, sustainable wastewater management, and green investment’, Specific Objective 2.3 ‘Developing smart energy systems, grids, and storage outside the TEN-E network’. This project has been designated as an ‘Operation of Strategic Importance’ due to its significant contribution to the achievement of national priorities for the 2021-2027 Programme. The ERDF funding allocated to this project amounts to €165,347,846.70.

Permiting
Maltese Permitting Procedure:
The Project Description Statement for the scope of the Maltese EIA screening was submitted to the Environment and Resources Authority in September 2021.
A Screening Decision was issued by the Authority in November 2021 where it was confirmed that the proposed development falls under Schedule I, Category II, Section 13.0.2.1 as well as Regulation 10 (3) of the Environmental Impact Assessment Regulations (S.L. 549.46).
The relevant documents can be accessed at this link.
Italian Permitting Procedure:
Meetings with Italian authorities have already been held in August 2021 during which a way forward was discussed. Similar to the Maltese section, it was confirmed that an Environmental impact assessment in line with the Decreto Legislativo 152/2006 is also required for the Italian Section of the Project.
Engineering
The second electrical interconnector project shall consist of an underwater and onshore cable link between the Maghtab terminal Station and the Ragusa 220kV substation in Sicily.
The second electrical interconnector project shall consist of an underwater and onshore cable link between the Maghtab terminal Station and the Ragusa 220kV substation in Sicily.
Similar to the first electrical interconnector, it shall have a nominal rating capacity of 225MW, and can operate in a bi-directional mode, generally importing electricity from Sicily, but being technically able to transmit electricity from Malta to Sicily should excess electricity produced in Malta be available in the future.
The terminal points of the project shall be the 220kV substation at Contrada Cimillà in Ragusa operated by Terna and the Maghtab terminal station at l-Għallis operated by Enemalta p.l.c.
The cable landing point in Malta shall be at l-Għallis while the landing point in Sicily shall be sited at Marina di Ragusa. Trenchless shore approaches shall be adopted in both countries to minimise the environmental and visual impacts on the shore at the proposed landing areas.
The cable will be buried along the onshore route with no overhead lines.
Commercial & Regulatory
objectives.Project Benefits
- To increase the electricity interconnectivity with the European electricity network for meeting the forecasted increase in the island’s electricity demand as a result of economic growth and the electrification of road transport.
- To cater for contingency/emergency situations such as temporary damage to the existing cable link.
- Contribute to Malta’s future strategy in reaching its 2030 climate and energy targets, and in the longer term, the 2050 decarbonisation objectives.
- Optimisation of local power generation
- Improve the security of energy supply by diversifying of energy sources.
- Enabler of an increase in locally generated electricity from renewables by supplying a buffer to counterbalance for RES intermittency.
