Polish power industry 2010. Selected results and preliminary comparisons of results achieved by power industry economic subjects in 2009
Energetyka 2010, nr 4, p. 201
Results achieved in the whole Polish power industry sector in the year 2009 were very favourable and almost three times better than in 2008. The biggest share in this success have the electric energy producers, the least of all – distribution system operators. Also the biggest growth of profit can be found in the energy production subsector while in the subsector of distribution it is visibly the smallest one.
Keywords: Polish power industry sector, economic subjects, comparison of results obtained in the years 2008 and 2009
Evaluation of Poland's electric power plants and public power and heating stations technical effectiveness with the use of Data Envelopment Analysis (DEA) method
Energetyka 2010, nr 4, p. 205
Presented is an influence of such factors like size of company, forms of ownership and type of activity on effectiveness and productivity changes with time of the electric energy and heat producers. The method used for this purpose was the DEA method and the research period comprised the years 2000-2004. At those times the investigated energy producers had at their disposal the maximum output capacity on the level of about 98%.
Keywords: technical effectiveness, electric power plants and CHP stations, productivity changes

Poland's energy security in connection with building of nucelar power plants
Energetyka 2010, nr 4, p. 212
Discussed are aspects of Poland's energy security. Attention is paid to big commercial power stations as well as to distributed power generation. Ascertained is the necessity of not only the substantial development of electric transmission and distribution networks but also bringing up to date the Energy Law.
Keywords: energy security, perspectives of the Polish power industry development, electric energy system
The road to the 4th generation nuclear power plants. Part one
Energetyka 2010, nr 4, p. 214
Described is the history of the first three generations of nuclear power plants based on a survey of many literature sources. Presented is the process of technological changes aiming to ensure the increase of the power plants' operational security. Described are some bigger failures of nuclear power plants.
Keywords: nuclear power plants, technological changes, three generations of nuclear power plants
The problems of interaction between nuclear power plants and a power system
Energetyka 2010, nr 4, p. 218
Considered are specific problems constraining the operational flexibility of nuclear power plants within a power grid. They are as follows: high nuclear power plants building investment costs forcing to operate plants at high load factors, transient xenon poisoning states caused by reactor power control and limits in safe permissible rate of reactor power increase due to pellet cladding interaction (PCI). It is shown that maneuvering abilitiy of a power plant to meet the demand of daily power fluctuations depends mainly on reactivity losses due to reactor xenon poisoning. And whereas the first two restrictions are in principle of economic character, the ones concerning limited rate of power increase result also from radiological reasons – in this particular case the problem lies in preventing fuel rods from damaging and the subsequent consequences.

Results of this year's independent power audit carried out in Odessa
Energetyka 2010, nr 4, p. 222
Presented are results of voltage measurement in many Odessa living quarters and described are problems and difficulties that the Ukrainian consumers of electric power and heat struggle with.

Russian power expansion and its implications for Poland
Energetyka 2010, nr 4, p. 226
The energy policy of every country is aimed at securing the current and future power demand. The reason is that energy is one of the main factors of economic development. That is why all countries of the world, in particular the developed ones, analyse their energy strategy and prognose their energy demand for a definite period according to current situation in the world. Attention is paid to influence of Russian energy policy on fuel and energy sector in our country. Outlined is also the situation in Russian energy sector showing in particular how Russia rebuilds its position as a world power, taking advantage of energy raw materials and using them as a weapon in the fight for its imperial interests.

Perspective possibilities to reduce CO2 emission from coal-fired power plants
Energetyka 2010, nr 4, p. 231
Discussed are perspective possibilities to reduce CO2 emission from coal-fired power plants. Results of investigation works raise our hopes of implementing the technologies enabling CO2 capture after the process of combustion with absorbents that will enable electric energy production with net efficiency of up to 45% (with 90% CCS). It means that the increase in coal consumption induced by CCS would fall from the at present anticipated 65% to even 9%.
Keywords: coal-fired power plants, CO2 emission reduction, combustion with absorbents

Justice in climatic policy. How the new member countries perceive their participation in the UE „climate leadership"
Energetyka 2010, nr 4, p. 252
Discussed are problems of a fair distribution of duties among the UE members. New member countries have repeatedly expressed their anxieties whether their participation in the proposed by the UE solutions is just. So far, facts show clearly that it has not been so. But we must remember that only justice in the frames of common and solidary effort of the whole UE, either in scope of emission reduction or financial obligations, can contribute to realization of the UE climate leadership idea and become a model for the future, wide involvement of all countries of the world.
Keywords: emission reduction, the UE climatic policy
