In December 2015 Greece notified plans to grant the Greek electricity
 company PPC a State guarantee, which would enable the company to secure
 a €190 million loan from the European Investment Bank (‘EIB’). The loan
 will cover half of the costs for the necessary upgrade, expansion and 
refurbishment of existing power plants on 18 islands not connected to 
the electricity grid of the mainland.
PPC will finance the other half of the costs from its own budget. The
 measure involves state aid, because the terms of the public loan are 
more favourable than those a commercial operator would have accepted. 
The Commission found that this aid is in line with EU rules, in 
particular the Commission’s 2011 rules on services of general economic 
interest (SGEI), since the measure is necessary to allow PPC to continue
 to supply consumers on the islands concerned with affordable 
electricity. It ensures the availability of the required electricity 
generation capacity on the islands concerned.
SGEI- Services of General Economic Interest are economic activities 
that would not be produced by market forces alone, or at least not in 
the form of an affordable service available indiscriminately to all. 
SGEI are carried out in the public interest under conditions defined by 
the State. SGEI range from large commercial activities, such as: postal 
services, energy supply, telecommunications or public transport, to 
social services, such as care for the elderly and disabled.
