The cost of electricity in Netsel Marina is .44 Euros per kilowatt which, at the present exchange, works out to 1.31 lira.
The cost of the same electricity for locals varies between .12 and .38 lira depending on the time of day which seems to indicate that Netsel has decided they need to make a profit of almost one lira for every kilowatt used by their clients.
Anyone considering wintering in Netsel should plan to spend minimum of 300 lira (100 Euros) per month if they use electric heaters for heating.
Would be interesting to learn what other marinas charge compared to the local rate but can't figure out how to organize a poll.
