Electricity is classified into two major categories depending on the type of energy sources used. These categories are:

  1. Conventional fuel power generation, which uses fossil fuels, liquids or gaseous fuels as sources of energy, formed in earlier geological periods and stored in the subsoil at shorter or greater depths in finite, non-renewable quantities,
  2. Renewable Energy Power Generation, which, unlike the former, uses timeless sources that do not exhaust limited energy reserves. RES power generation is directly related to the sun and natural phenomena and therefore depends on the periodicity or stochasticity of these phenomena.

Each country has chosen its own mix of Power Generation Technologies. This mixture varies from country to country because it is determined by factors such as:

  1. the available Domestic Energy Resources,
  2. International Conjunctions & Energy Policy,
  3. the geological, geophysical, geographical and climatic features.

Observing the graph of the evolution of installed power generation in Greece for the period from 1990 to 2007, we find the following:

  1. Most of the installed power generation is based on lignite, as it is a domestic product and is abundant in many deposits in mainland Greece.
  2. The stable, relatively large proportion of installed power generation based on oil and its products, mainly due to the large number of Greek islands and their interconnection difficulties.
  3. The fixed percentage of hydroelectric plants installed, which require huge environmental interventions to create dams and water reservoirs for their construction
  4. The first appearance and the gradual increase of the power plants using Natural Gas after the construction of the PV transmission pipeline in our country.

The small but continuous increase in installed wind power plants and the signaling of a new era for RES penetration.

Until today, developments are catastrophic. HELLAS ENERGY all these years has always been present, next to you steadily and responsibly, with products and services. Twenty years (March 1995) together and we continue…
