Smart Islands

We are the Operator of Non-Interconnected Islands (NII). Our priority is effective energy planning for the islands and the development of suitable infrastructure, aiming to:

  • Reduce operational costs
  • Increase the penetration of Renewable Energy Sources (RES)
  • Ensure the adequacy and safe operation of the electrical systems

As a Non-Interconnected Islands (NII) Operator (and in compliance with the institutional framework currently in force), HEDNO is responsible for the operation, management and safety of the NII electricity systems whilst also acting as a market operator.
NII management is particularly complex and challenging due to the peculiarity and distinctive features of our country’s NIIs (geographical, population, demographics, etc.) as well as the difficulties experienced in achieving the goals mentioned above.

HEDNO’s operational planning involves very specific strategic projects for the NIIs, which are key to the modernization and upgrading of the autonomous Electricity Systems (ES).

Special mention is given to the development of Special Pilot Projects (SPPs – Smart Islands) pertaining to the implementation of Hybrid Stations (with at least one RES and a sufficient storage system) as well as sufficient infrastructure for the operation and management of both Hybrid Stations and all Electricity Systems that will receive SPPs.

Goals of the SPPs:

1

Contain operational costs of ES by reducing fuel consumption in thermal units

2

Achieve high RES penetration (over 60%) while ensuring system adequacy and safety

The results coming from these innovative projects are expected to be used as operational and management models for all other Electricity Systems and NIIs based on RES power generation and the use of storage units.

Furthermore, the Greek “Smart Islands” operational and management model can be used as an example for the operation of large interconnected systems with very high RES penetration, based on the climate objectives set out by the EU and the “Clean Energy for All European Islands” initiative.
