- Location: Cyclades Islands, Aegean Sea (Greece)
- Peak power: 170 MW
- Technology: Zigor MIT3 NG 110v
The project for the electrical interconnection of the first group of Cyclades Syros islands with Lavrio and Tinos, Paros and Mykonos by submarine wiring, with the continental electricity network aims to reduce the high costs of electricity and pollutants in the energy system more intensive in consumption of coal from Europe.
- Significant reduction of fuel costs (or that will reduce the cost of electricity production by 80 million euros per year).
- It will allow significant savings of high investment costs for the development and conversion of local power plants.
- It will contribute to the reduction (and in the long term elimination) of CO2 pollutants and associated costs.
- Optimization of fuel logistics and energy cost compared to traditional generation sources.
The particularity of the Greek energy system is the large number of islands that surround the mainland. The Greek islands, with 1,300,000 inhabitants, are divided into several archipelagos with more than 2,000 islands, of which only about 200 are inhabited.
One of the main problems facing Greece is the security of the electric power supply system.
The local power plants of the islands use fossil fuel (oil, hydrocarbons and lignite) to cover more than 80% of the final energy demand, which means very high production costs compared to power plants located in the Continental System 
The existing production units on the islands are old and with few factors of efficiency and installed capacity that can not satisfy the growing demand, and which require substantial investments to improve their capacity.
The Interconnection project of the Cyclades Islands is a technically complex transmission project that will be completed in three phases. It will guarantee the reliable, economic and sufficient supply of electricity to the Syros, Paros, Tinos, Mykonos and Naxos islands during the next 30- 40 years using submarine cables with a nominal capacity of 140-200 MVA.
This interconnection project has been completed with the construction of 4 GIS type substations of 150/20 Kw / MV in which the Zigor MIT NG + Battery Pack three-phase battery rectifiers / chargers will guarantee the backup of the critical functions of the electrical substation as: protection, operations, signaling and emergency lighting.
In Normal Operations, the Zigor MIT NG charger output current guarantees the power supply to the main DC panel, and at the same time, it is able to maintain the full charge of the battery banks. The batteries will contribute to the supply of power to the main panel when the load demand of the panel exceeds the value of the nominal operating load of the charger and when there is an emergency situation in the absence of AC voltage. Since these are reversible redundant power systems, in case of failure in the main system, the automatic transfer is made to the equipment that remains in stand-by without the critical loads fed through the DC distribution board of the center suffering any interruption of supply.
Likewise, in the absence of AC voltage, the batteries of the system continue to provide power up to their autonomy limit.
Once the power supply voltage has been restored to either charger, the main charger will automatically resume power to the main DC Panel and recharge the batteries.
