There are approximately 30 high voltage (HV) consumers in Greece, consuming 1,000 ΜW from the production capacity installed in the country and representing 10-12% of the monthly supply of all participants in the Day-Ahead Scheduling (DAS). Given the technical capacity and long experience in respect of the special electrical characteristics of large system consumers, each HV consumer is able to negotiate specific terms for the supply contracts, such as the provision of interruptible load services during peak hours, i.e. quasi capacity reserve, to ensure favorable tariffs during other hours.
The number of HV consumers on the Greek System is limited. However, due to their increased demand for electricity, significant incentives must be given to encourage these consumers to plan their demand during System non-peak hours, i.e. to reduce the amounts of electricity they consume in periods in which there is peak demand from other System loads. The option of concluding interruptibility contracts with the Independent Power Transmission Operator (ADMIE) for load transfer from peak demand zones to medium/low demand zones is expected to serve as an important tool in rationalizing the overall demand on the System and cutting down on electricity costs for the most energy consuming industries in Greece.
HERON remains at the disposal of all consumers for transferring know-how, establishing creative cooperation, offering all-around energy services and elaborating specific actions with a view to optimizing the energy profile of plants in respect of the estimated cost of electricity.
