On 10 June 2026, the 3rd Workshop on Electric Vehicle Charging Infrastructure was held, continuing an ongoing initiative to promote structured dialogue between HEDNO, the State, and stakeholders from the e-mobility sector.
The Workshop was organized on the initiative of Dimitris Skylogiannis, member of the HELIEV, Kostas Mathioudakis, the Institute’s financial officer, also participated as a panel speaker. The discussion brought together representatives of Charge Point Operators (CPOs), executives from HEDNO, and a representative of the Ministry of Infrastructure and Transport. The Workshop focused on key technical, regulatory and procedural issues affecting the deployment of EV charging infrastructure and, more broadly, the advancement of electric mobility in Greece.
HEDNO’s Methodology for Grid Connection Offers
A central topic of the Workshop was HEDNO’s comprehensive presentation of the methodology used to calculate Grid Connection Offers for both Low Voltage and Medium Voltage connections.
The presentation explained the principal factors that determine the connection cost of an EV charging installation, distinguishing between standardized connection charges and project-specific costs arising from the particular technical characteristics of each installation. It also clarified the circumstances under which extensions, reinforcements or upgrades of the existing distribution network may be required.
Particular emphasis was placed on the further development of HEDNO’s digital Connection Cost Estimation Tool, enabling investors and CPOs to obtain, at the earliest stages of project planning, a more accurate assessment of:
• the estimated grid connection cost
• any required network reinforcement or extension works
• the applicable technical requirements
• the expected timeframe for completion of the grid connection
V2G, V2H and V2B Technologies
A second major theme of the Workshop was the growing role of Vehicle-to-Grid(V2G), Vehicle-to-Home (V2H) and Vehicle-to-Building (V2B) technologies.
Bidirectional charging technologies fundamentally transform the role of electric vehicles. Rather than functioning solely as electricity consumers, EVs can become active components of a broader and more flexible energy ecosystem.
Subject to the appropriate technical, contractual and regulatory framework, the energy stored in an EV battery can be exported in a controlled manner:
• to the electricity grid through V2G applications
• to residential premises through V2H applications
The successful implementation of these technologies requires, among other
elements:
• bidirectional EV chargers
• smart and appropriately configured electricity meters
• close cooperation with vehicle manufacturers
• separate metering of imported and exported electricity
• clearly defined import and export power limits
• safe operation under communication failure conditions
• interoperability between the electric vehicle, charging equipment, Energy
Management Systems (EMS), service providers and the Distribution System Operator (DSO)
Particular attention was given to the regulatory framework that will be required for the deployment of V2G and V2H services in Greece, including their participation in the electricity market and the technical specifications that installations and equipment will need to satisfy.
Additional Topics Covered
The agenda of the 3rd Workshop also included discussions on:
• implementation of the Alternative Fuels Infrastructure Regulation (AFIR)
• hybrid EVSE–PV–BESS systems
• integration of photovoltaic systems, battery energy storage systems and DC fast charging infrastructure
• dynamic electricity pricing
• deployment and utilization of smart meters
• monitoring of grid connection applications through dedicated CPO corporate accounts
• the establishment of clear metering requirements for publicly accessible EV charging stations
The successful organization of the third Workshop highlights the importance of sustained and institutionally coordinated cooperation between HEDNO, the Ministry of Infrastructure and Transport, and professional stakeholders across the e-mobility sector.
Such collaboration is essential to ensuring that the expansion of EV charging infrastructure in Greece proceeds with technical reliability, transparency, predictability, interoperability and a common regulatory framework that supports both investors and the broader transition to sustainable mobility.
