There are a lot of questions posed daily to PPC by politicians, customers, employees and public. Possible questions posed by the public should be foreseen as well as their relevant answers.
Possible question: Which are the environmental advantages assured by the artificial lakes of PPC?
Apart from the generation of clean energy, HPPs with Artificial Lakes are considered as projects with multiple purposes:
• They provide downstream flood protection
• They assure water efficiency regarding the coverage of needs (water supply of cities, irrigations, other uses) and during droughts.
• They assure permanent water supply to the river beds so as to maintain the ecosystems.
• They constitute the ideal environment of survival and development of fauna and flora species.
• They upgrade the landscape aesthetically and in many cases, they constitute wetlands habitats of unique natural beauty.
• They provide the possibility of activities development such as fishing, athletic and recreational activities, environmental training, alternative tourism etc.
Possible question: Which actions does PPC undertake for the prevention and control on pollutant emissions from thermal Plants?
PPC realizes actions that aim at the control and reduction of sulphur dioxide SO2 emissions, nitrogen oxide NOx emissions as well as particles emission (dust) from major combustion installations in which solid or liquid fuels are used, contributing to the country’s effort for the achievement of the goals deriving from the National Emission Reduction Plan (NERP) and from the environmental Directive 2001/80/EC on the limitation of atmospheric pollutants emissions.
PPC’s actions for the prevention and monitoring of the pollutant emissions from thermal power Plants refer mainly to actions of monitoring and improvement of used fuels such as the mixture of lignite for the supply of Kardia and Ag. Dimitrios TPPs, the supply with oil fuel of low sulphur fuel oil (containing 1% by weight in sulphur) to all oil-fired plants which use oil fuel, the operation of fuel desulphurization systems in Units ΙΙΙ of Megalopoli A’ TPP, IV of Megalopoli B’ TPP and in Meliti TPP, the replacement, upgrading and addition of new state-of-the art electrostatic Precipitators (ESPs) with high degree of efficiency for ash in lignite Plants.
In application of article 32 of the new Directive 2010/75/EC, on industrial emissions, Greece has elaborated and submitted for approval to the European Commission the Transitive National Emission Reduction Plan referring to Units Ι-V of TPP Ag. Dimitrios, the Units ΙΙΙ and IV of Kardia TPP, ΙΙΙ of Megalopoli A TPP, IV of Megalopoli B TPP and Ι of Meliti TPP. The Transitive National Emission Reduction Plan approved by the European Commission in 2013.
The Transitive National Emission Reduction Plan has a duration from 01.01.2016 until 30.06.2020 and imposes linear reduction (between 2016 and 2019) of the total annual emissions for sulphur dioxide and particulate matter emissions in the Units providing the possibility for gradual implementation of the necessary environmental investments in them.
For NΟx emissions, compliance is already required from 01.01.2016.
In December 2013, PPC requested the amendment of the Transitive National Emission Reduction Plan for the non-inclusion of the Units III & IV of Kardia TPP.
The amended Transitive National Emission Reduction Plan will have to be approved by the Ministry of Environment, Energy and Climate Change and then by the European Commission. Also, PPC requested for the integration into the status of limited duration derogation from article 33, 2010/75/EC for the time period 01.01.2016-31.12.2023 referring to the following Units:
Ι – ΙΙ of Amyntaio TPP
Ι , ΙΙ, ΙΙΙ and ΙV of Kardia TPP
For keeping the Transitive National Emission Reduction Plan, PPC decided in 2012 the construction of works for dry desulphurization of fuels with possible selection of the wet method for fuel desulphurization in the Units I-IV of Ag. Dimitrios TPP, depending on the results of the tests in progress in Unit III and the project construction using the wet method of fuel desulphurization in Unit V of Ag. Dimitrios TPP.
For keeping the Transitive National Emission Reduction Plan, PPC decided:
- Τhe construction of projects for dry desulphurization of fuels with possible selection for the wet method of fuel desulphurization in Units I-IV of Ag. Dimitrios TPP depending on the results of the tests in progress in Unit III and construction of a project for using the wet method of fuel desulphurization in Unit V of Ag. Dimitrios TPP.
- Τhe construction of projects for the reduction of ΝΟx emissions, with extensive primary measures in Units Ι-ΙV of Ag.Dimitrios TPP and smaller scale interventions with primary measures in Unit V of Agios Dimitrios TPP and Megalopoli B TPP.
Possible question: Which actions does PPC take for the reduction of CO2 emissions from thermal Power Plants?
For the limitation of CO2 emissions of thermal power Plants, the Corporation implements actions and programs that include investments for the replacement of old Power Plants with new state-of-the art technology and high performance so as to modernize the existing installation and their operation using of the existing facilities and operation on the basis of the Best Available Techniques, for improvement of energy mix characteristics so as to further develop Hydroelectric Plants and Renewable Energy Sources projects for the promotion of saving actions and rationalized use of electricity.
Also, PPC participates in research programs and is constantly informed on the application of efficient technologies for lignite as well as the development of CO2 capture and storage.
Possible question: Can you mention some facts concerning Teleheating that PPC provides to its activity areas?
PPC, through programs that are developed with the cooperation of the local Municipalities and the competent Municipal Companies, exploits heating that is generated by thermal lignite power plants in Western Macedonia and Arkadia and provides heating with the form of hot water for coverage of the heating needs for rural use in Kozani, Ptolemaida, Amyntaio and Megalopoli. The cost for the provision of thermal energy with the method of Teleheating is significantly lower than other conventional heating methods.
The provision of teleheating constitutes a model for sustainable management as well as it is characterized by multiple benefits for all interested parties; the most significant is the reduction of air pollution, due to the avoidance of combustion of hydrocarbons and wood for heating purposes and financial benefits that emerge for the local societies due to reduced cost of heating.
In 2012, two additional Power Plants were integrated into the teleheating program, that is, Kardia III and Kardia IV, which provide thermal energy to the city of Ptolemaida. Teleheating is planned for the city of Florina.
Possible question: Can you inform us on how Hydroelectric Power Plants contribute to the reduction of CO2 emissions?
Answer: The electricity generation from Hydroelectric Power Plants is zero for CO2 emissions. In periods in which there is sufficient water, electricity generation from Hydroelectric Power Plants substitutes the electricity generation from Thermal Power Plants.
