Strategic Transformation and Digitisation
The strategic projects included in our new strategic plan mark the course of the HEDNO in the near future.
Strategy, Modernisation & Innovation
We aim to be a modern network management company through digitised operations, modernisation of our systems and new planning and development tools.
Growth and modernisation through the Strategic Projects
In our new business plan, we include Strategic Projects, which are both a central axis and a catalyst for the modernization of our company, while marking our path for the near future.
These projects are part of the Transformation Programme of the BPA towards a modern Network Management Company through digitised operations and new tools for planning and deployment of the Distribution Network across the mainland and the Non-Interconnected Islands.
Greece in the new era of Smart Grids
Our strategic projects create the basic conditions for Greece to enter the new era of Smart Grids, on the basis of which new markets for services and products can be developed in a constantly changing electricity market. The electricity sector has entered a period of radical change internationally, both technologically and in terms of business, and we at HEDNO are seeking to develop the necessary infrastructure with the maximum possible benefit for the economy, society and the environment.
The Strategic Projects cover a wide range of modernization activities, such as Smart Grids, Telemetering of consumption, Tele-customer service and automation in many internal operations, always keeping an eye on new trends in the electricity sector.
Benefits of the projects
The benefits expected from the implementation of the Strategic Projects, in combination with the company’s fixed objectives, are:
improving the quality of energy and services provided to customers, while reducing the company's operating costs
improving working conditions for its staff
the more efficient operation of the electricity market
the protection of the environment by increasing the penetration of Renewable Energy Sources (RES)

Quality of the services provided
At HEDNO we aim at providing better quality services to our Customers and we are committed to you mainly in two ways:
- the Ministerial Decision of 2007 (Δ5/ΗΛ/Β/Φ1.10/6636/26.03.2007) which defines the time of response to Customers’ requests for power supply.
- Under the “Guaranteed Services” program that has been in effect from 1/4/2014 (approved by RAE).
At the same time, two main indicators are monitored to determine the quality of the provided energy:

Average frequency interruptions per customer (SAIFI)
Aiming at further improvement of the service quality indexes (duration for power supply studies and constructions) and energy quality indexes (decrease of the number of failures, minimization of restoration time, improvement of the provided voltage, etc.) along with the reduction of the operating cost and the increase of productivity, we proceed to important investments in networks relative to:
- Increase of network sufficiency for the coverage of the demand.
- Ensure further enhancement of the Network reliability
- Network development and work automation
