Poland has insufficient natural gas resources to satisfy its needs. That is why it has been dependent on the imports of that raw material. One of the challenges facing the Polish government is limiting Poland’s dependency on Russian gas. The objective of the paper is to present the directions of the Polish government’s energy security policy in terms of natural gas in the years of 2015-2018. Particular attention was paid to the assumptions and the implementation of the government’s gas policy in terms of the situation in the European Union gas market. An attempt was made to answer the question: To what extent have the assumptions of policy of the government of the Law and Justice party regarding Poland’s gas security been realized? In an attempt to answer the question so formulated, the following methods were used in the study: a decision-making method, formal-legal method, statistical and comparative methods. On the grounds of the conducted research, it needs to be concluded that after 2015, as a result of the government’s policy, the imports of natural gas from the east to Poland were reduced with a simultaneous diversification of the direction from which this raw material was delivered. The resignation from the deliveries of Russian gas to Poland after 2022 will be possible thanks to putting Baltic Pipe gas pipeline into operation and raising the flow capacity of Świnoujście LNG terminal. The implementation of these investments will have a positive impact on the improvement of Poland’s gas security. Failure to launch the investments and an increase of gas consumption in Poland will make it necessary to conclude a short-term Polish-Russian agreement for imports of that fuel to Poland.
