Power utility PPC has admitted it does not have enough time to convert old, high-polluting diesel-fueled power stations operating on Crete into natural gas-fueled units by 2020, as it had previously assured, energypress sources have informed.

Though the island does not appear likely to experience an energy sufficiency problem, the cost of preventing a shortage will be considerable and will be covered by consumers around the country through elevated public service compensation (YKO) surcharges included on electricity bills.

Crete’s ageing diesel-fueled units, offering a total capacity of 100 MW, were given lifespan extensions in June through a legislative amendment delivered by the previous energy minister Giorgos Stathakis, without EU approval. EU fines cannot be ruled out.

This additional operating time is intended to provide cover until the launch of a small-scale grid interconnection to link Crete with the Peloponnese, expected at the end of 2020. A large-scale interconnection linking Crete with Athens is expected in 2023.

The conversion of the old power stations into gas-fueled units has constituted part of an overall plan to ensure energy sufficiency on Crete between 2020 and 2023.

Besides the high cost entailed in running these old power units, energy sufficiency on Crete is made even more expensive by high-priced leasing costs of power generators deployed on the island every summer to meet higher tourism-related electricity demand.

Plans for the installation of an FSRU off Crete appear to have also run into problems. Gas grid operator DESFA has proposed a bigger and permanent onshore LNG terminal installation.
