Malta Microgrid pilot: the Gozo island solution

Share this Post:

The PEGASUS Interreg MED project (Promoting Effective Generation and Sustainable USes of electricity) aims to give evidence of the feasibility of microgrids acting on technical or administrative obstacles which are hindering the use of microgrids in disadvantaged areas; a tested business model will show advantages of smart interconnection and facilitate the adoption of necessary acts to define an ENABLING environment. The innovative approach of PEGASUS focused on experimenting a simulation of functioning of microgrids in 7 pilot areas jointly; solutions will be based on concrete situation with real data.

 

The Malta pilot site is located on the island of Gozo consists of 15 public and private buildings, having both consumers and prosumers profiles. The pilot is characterised by the following buildings: Ministry for Gozo (1 large PV system 108 kWp – 166 MWh annual electricity generated)), San Lawrenz Local Council (Prosumer with 1 PV system of 34.5 kWp –50 MWh annual electricity generated), 1 small office/commercial building and 12 residential households (7 consumers, 5 prosumers for a total of 22 MWh annual electricity generated). MIEMA consulted different business models considering technical and financial aspects.

 

The pilot is addressed to investigate a grid-connected community micro-grid model which represents small municipalities. Analysis and prediction of energy requirements would allow the micro-grid to be disconnected from the main grid (islanding) in case of main grid failure. Energy monitoring started in November 2017, with measurements being taken every minute.

 

The main objective of the Malta pilot is to simulate a micro-grid operation, including storage systems and different feed-in electricity tariffs. The micro-grid model also aims to reduce the costs of energy for the micro-grid community members, to provide a more reliable energy supply by using renewable sources (possibly in conjunction with energy storage) and to reduce losses in upstream distribution network.
