Introduction
The Greek energy sector is still largely dependent on fossil fuels, most of which are imported. About 54% of its energy requirements are covered by petroleum products alone, compared to an average of 33.4% at the EU level. These petroleum products are not only used in the transport sector, but they are also converted in relevant amounts into electricity. In particular, the non-interconnected Greek islands obtain their electricity primarily from inefficient and expensive diesel generators. In total, the extra cost that has to be recovered through a public service obligation accounted for around 771 m € for the year 2013 to subsidise the electricity tariffs in those areas. Natural gas, which also has to be imported at a significant cost, plays a growing role in meeting energy requirements.
Domestic energy sources include lignite which accounts for around 50% of electricity generation as well as renewable energy sources (RES) such as hydro-power, wind, solar energy and biomass. RES currently account for 15.4% of gross final energy consumption. A national target of a 20% share in gross final energy consumption by 2020 has been defined under Law 3851/2010, exceeding the national target of 18% according to the EU Directive 2009/28/EC. The specific trajectory for achieving this target is presented in the National Renewable Energy Action Plan (NREAP) of 2010. Specific targets for RES electricity share (40%), RES heating and cooling share (20%), and RES transport share (10%) have been defined in order to achieve the national RES target until 2020. This target is supposed to be achieved through a combination of measures for energy efficiency and the large-scale penetration of RES technologies in electricity production, heat supply and transport sector.
The outcomes of the energy sector modelling carried out in the scope of compiling the Greek NREAP demonstrated that a near tripling of the contribution of RES plants in power generation is necessary for meeting the 2020 targets which requires the further development of different RES technologies in the sectors of electricity, heat and cooling, and transport. These figures are however currently being revised in the context of the national energy planning, taking into consideration the lower than expected levels of energy consumption due to the economic crisis as well as the differences between the NREAP and the actual development of different RES technologies.
A number of significant reforms aiming at a further liberalization of the energy sector, its integration with neighbouring countries and the reform of energy markets are currently being implemented. In addition, the Greek support scheme for electricity production from RES is currently undergoing a major transition in order to improve the integration of RES in electricity market and to ensure conformity with requirements under EU state aid regulations. There are also plans for large infrastructure projects in the electricity, gas and petroleum sector that are supposed to strengthen Greece’s position as an energy hub in the South-East of Europe.
Energy Supply
Primary Energy
Around 61% of Greece’s energy needs are covered through imports with the remaining 39% being covered through national energy sources, mainly lignite (77%) and RES (22%). Imported energy sources are mainly petroleum products that account for 44% of total energy consumption and natural gas with a share of around 13%.
Electricity generation
According to the Greek Electricity Market Operator (LAGIE), the total installed capacity in the Greek interconnected system at the end of 2015 accounted for almost 18,087 MW, including 4,456 MW lignite, 698 MW oil-fired plants, 5,170 MW natural gas, 3,173 MW large hydro-power and 4,590 MW RES. The total electricity generation in the Greek interconnected system for the year 2015 amounted to almost 41.2 TWh. An additional 9.4 TWh of electricity was imported. Lignite accounted for 49% of electricity generation in the interconnected system, natural gas for 20.2%, and RES (including large hydro-power) for 30.5%. According to theHellenic Electricity Distribution Network Operator (HEDNO),on the non-interconnected islands (NII), the diesel-driven generators’ capacity was 1,753 MW by December 2015, producing a total of 323 MWh. The renewable energy share in the electricity mix of the NII was 19%, which equals a production of 90,049 MWh and an installed capacity of 453 MW.
During the year 2015, an additional capacity of 121 MW of RES has been installed in Greece, including 113 MW of wind energy and 8 MW of photovoltaic energy. The total installed capacity and electricity production from roof-top PV systems under the Special Program at the end of 2015 amounted to 375 MW and 494 GWh, respectively.
Energy Consumption
Primary energy
Total energy consumption in Greece was around 27 million tons of oil equivalent (TOE) in 2012. Final energy consumption was 16 million TOE in 2012, a decrease of around 24% since the beginning of the economic crisis.
Electricity
Gross national electricity consumption in 2012 was 55 TWh, including transmission and distribution losses of 2.9%. The annual peak load in the interconnected system currently stands at around 9,000 MW.
Electricity tariffs in the first half of 2013 for final consumers were on average 156 €/MWh for households and 125 €/MWh for industrial companies, after an increase of 25% and 16% respectively from 2011.
Market Situation for Renewable Energies
Solar Energy
Solar energy is playing an increasingly important part in the energy mix of Greece. The country has high levels of solar irradiation with an average global horizontal irradiation level of more than 1,500 kWh/m2.
Photovoltaic energy has seen a significant increase in capacity over the past 2 years from 620 MW by the end of 2011 to 2,520 MW in September 2013 due to very high feed-in tariff levels. The current national capacity target for photovoltaic energy of 2,200 MW by 2020 has therefore already been achieved in 2013.
Today, 14,369 mainly small and medium sized PV plants are installed, corresponding to a capacity of 2,154 MW. In addition, 40,537 small PV systems are installed on rooftops corresponding to an additional capacity of approximately 366 ΜW. Only 6.2% of the total PV capacity is installed on non-interconnected islands.
There are currently no concentrated solar power (CSP) plants installed in Greece. There are some sites with direct irradiation levels over 2,000 kWh/m2/year on the Southern Greek islands that could be interesting for CSP. Several projects with a combined capacity of 424 MW are currently under development. The national target for CSP is 250 MW until 2020.
With around 4.1 million m2 (2.9 GWth) of solar thermal systems installed, Greece has the second largest total capacity in Europe after Germany. It also has the third largest per capita ratio of installed collector surface after Cyprus and Austria. Around 243 000 m² (170.1 MWth) of solar thermal systems have been installed in 2012. The Greek market mostly consists of individual solar water heaters of the thermosiphon type. There is still a significant potential for larger solar thermal systems in the tertiary sector and in industry.
Wind Energy
Greece has some of the most attractive sites for the use of wind energy in Europe, with average capacity factors of around 25% for the mainland and 30% for the islands. The economic wind energy potential in Greece is estimated at 10,000-12,000 MW.
The national capacity target for wind energy is 7,500 MW until 2020, including 300 MW of offshore wind energy. At the end of 2013, a total capacity of 1,809 MW of wind parks has been installed, compared to 1,749 MW in 2012 and 1,634 MW in 2011. 288 MW of wind turbines have been installed on non-interconnected islands, out of which around 70% have been installed on Crete.
Off-shore wind turbines have not yet been installed, with the main reasons to be found both at difficulties in the environmental permitting procedure and technical problems mainly due to the depths of the Aegean sea floor. There are plans to introduce a new programme for small wind energy turbines with capacities below 50 kW starting from mid-2014.
Small hydro-power
There is currently an installed capacity of 218 MW of small hydro-power (SHP) plants in Greece. By definition, these are hydro-power stations with a capacity less than 15 MW. Due to the high fluctuation of rainfall, the majority of these plants produce mainly during the wet season (winter and spring). They are all run-off river type, without any kind of reservoir. Around 104 SHP projects are currently in operation, mostly located in Epirus, Macedonia and Peloponnese. The economic SHP potential in Greece is estimated at 1,000- 2,000 MW.
Biomass
There are only few biomass energy projects for electricity generation that have been developed in Greece, mainly for the utilization of municipal wastes in biogas plants. There is still a large potential for the utilisation of biomass for energy purposes, especially biomass waste and residues from the agricultural, industrial and residential sectors. The total installed capacity of biomass energy currently stands at 46 MW for a total of 12 individual projects. This compares with an intermediated national target of 80 MW for 2013 and 250 MW by 2020 according to the National Renewable Energy Action Plan (NREAP).
Geothermal
Greece lies in a geographic position that is favorable to geothermal resources, both high temperature and low temperature. High temperature resources, suitable for power generation coupled with heating and cooling, are found at depths of 1-2 kilometres on the Aegean islands of Milos, Santorini, and Nisyros. Other locations that are promising at depths of 2-3 kilometers are on the islands of Lesvos, Chios, and Samothraki as well as the basins of Central-Eastern Macedonia and Thrace.
Low temperature geothermal resources are found at the plains of Macedonia-Thrace and in the vicinity of each of the 56 hot springs found in Greece. These areas include Loutra-Samothrakis, Lesvos, Chios, Alexandroupolis, Serres, Thermopyles, Chalkidiki, and many others.
Low temperature geothermal applications include space heating and in agricultural uses (greenhouse heating, the drying of fruits and vegetables, aquaculture and seawater desalination, and in spas), providing an ideal synergy with other widespread commercial ventures in Greece.
Geothermal projects for electricity generation have not yet been developed in Greece. The national target for geothermal electricity is 120 MW until 2020.
Biofuel
Greece has a national target of 10% renewable energy in the transport sector. The largest share of this is supposed to come from biofuels. The RES share in the transport sector was around 1.06% in 2012. National regulation obliges Greek refineries to blend at least 5% of biofuels in their production. Biodiesel quantities are allocated every year after a relevant call for tenders and following a specific procedure to stakeholders, producers or importers, who are interested in participating in this quota system.
Currently, only biodiesel is being commercialized in Greece. Around two thirds of the production is imported, the rest is produced locally, mainly from sun flowers and rapeseed. So far, bioethanol as well as second and third generation biofuels have not been introduced in the Greek market.
Policy Framework, Laws and Regulations
General Energy Policy, Energy Strategy [1]
The priority and top objective of Greek energy policy is to safeguard and manage energy resources in a manner which secures the smooth, uninterrupted and reliable supply of the nation’s energy needs and access for all users to affordable, secure energy. The second objective is to secure energy stocks, through alliances and alternatives energy sources and routes in order to ensure the supply of the domestic market and protect consumers in the case of emergencies. The third objective is the viable and sustainable development of the energy sector from the stage of production to the end-use while protecting nature and safeguarding the environment.
The strategy to ensure supply needs and address energy issues in Greece is shaped by the regulatory and legal framework which focuses today on the following general axis:
- Access to a wide variety of energy sources
- Construction of oil and natural gas pipelines within international networks
- Increased use of domestic energy sources and stocks
- Reduced dependence on certain high risk energy sources
- Development of RES installations with the granting of incentives
- Use and diffusion of clean and efficient environment friendly technologies
- Liberalization of the market, increased competitiveness and putting an end to monopolies in the electricity and natural gas sectors.
- Establishment of a healthy investment climate for businesses in the energy sector
- Energy savings for industry, transport, buildings and homes
- Establishment of national targets for the increased penetration of energy generated from RES, the reduction of greenhouse gas emissions and energy saving.
Important Laws and Regulations
Renewable Energy Laws[2]
The support mechanism for electricity generation from renewable energy sources is based mainly on Law 3468/2006 and Law 3851/2010. According to these laws, priority is given for the injection of electricity from RES into the electricity grid. The electricity produced is remunerated by a technology-specific feed-in tariff (FIT). These FIT are further differentiated according to the size of the RES installation with smaller systems benefitting from higher FIT. Payment of the FIT is guaranteed for a period of 20 years (25 years for small PV systems and solar thermal power plants) in the context of a sales contract (Power Purchase Agreement – PPA). Regular degression rates are currently only applied to FIT for photovoltaic energy systems. FIT levels are adjusted annually by a certain percentage of the consumer price index to take into consideration the inflation of operating costs. FIT for small hydro-power, geothermal stations and biomass energy systems are increased by 15-20% if the investor of the RES plant decides not to apply for an investment subsidy under the national investment law which accounts for 20-40% of investment costs. Wind energy and photovoltaic energy systems are not entitled to investment grants but they can benefit from tax incentives.
Licensing procedures for renewable energy projects
The licensing procedure for RES projects has been significantly simplified in 2010. Larger RES projects require a production license (issued by RAE), an installation license (issued by YPEKA or by local authorities) and an operation license (issued by YPEKA or by local authorities). Small and medium sized RES projects (PV and biomass plants ≤ 1 MW, geothermal stations ≤ 500 kW, wind parks ≤ 100 kW) do not require the above licenses. In addition, other licenses (water use, building permit, use of forest land…) as well as an Approval of Environment Terms (AET) or Standard Environmental Commitments (SEC) are required according to the nature of the project. All RES projects have to submit applications for non-binding and binding connection offers to the competent network operator (IPTO or HEDNO). They are also required to sign a connection contract with the competent network operator (IPTO or HEDNO) as well as a PPA with LAGIE (or HEDNO for the non-interconnected islands).
The RES electricity compensation mechanism
FIT are paid to RES producers through the RES Special Account which is managed by the Electricity Market Operator (LAGIE). The revenues of this account include the following:
- Revenues of LAGIE from the sale of RES electricity on the wholesale market at the system marginal price (SMP)
- Revenues from the auctioning of greenhouse gas emission allowances
- 25% of the fee for the Public Broadcast Company
- Special fee of 2€/MWh for electricity produced by lignite
- Special Fee for the Reduction of Greenhouse Gases Emissions (ETMEAR)
The ETMEAR which is collected through electricity bills varies between different categories of final consumers. The ETMEAR has been increased several times since 2011 when it stood at 1.84 €/MWh. The last revision was in July 2013, with an increase of the weighted average ETMEAR from 9.30 €/MWh to 14.96 €/MWh. For households, the ETMEAR currently stands at 20.5 €/MWh.
Specific Strategies
National Action Plan 20-20-20 [3]
According to the EU Directive 2009/28/EC, Greece has to achieve a target of 18% renewable energy sources (RES) in gross final energy consumption by 2020. This target has been increased to 20% (Law 3851/2010), while the specific trajectory for achieving it is presented in the National Renewable Energy Action Plan (NREAP) of 2010. The overall target is broken down further into sub-targets of 40% RES in gross electricity consumption, 20% RES in final energy consumption for heating and cooling, and 10% RES in final energy consumption for transport until 2020.
Institutional Set-up in the Energy Sector
Ministry of Environment, Energy and Climate Change (MEECC/YPEKA)
The Ministry of Environment, Energy and Climate Change (MEECC/YPEKA) has the responsibility for the definition and implementation of the national energy policy as well as the coordination of the energy sector, including the promotion of renewable energy sources.

Operator of the Electricity Market (LAGIE)
LAGIE has the responsibility for the operation of the electricity market according to the mandatory pool model. Fossil fuel and large hydro electricity producers submit their offers to LAGIE that organises the day-ahead market based on these offers. For the case of RES, LAGIE concludes power purchase agreements (PPA) with RES producers based on the current feed-in tariffs (FIT). These FIT are paid from the RES Special Account which is also managed by LAGIE. For the non-interconnected islands, the funds are transferred by LAGIE to HEDNO. Apart from the short term wholesale electricity market, LAGIE also has the responsibility for managing the long term capacity market as well as the imbalance settlement mechanism.
