This Decree prescribes the types of measures to reduce carbon dioxide equivalent (CO₂eq) emissions and the method of reporting on implemented emission reduction measures. Emission reduction measures, for which the right to a tax credit may be exercised in accordance with the Law on greenhouse gas emissions tax, shall include exclusively activities that lead to a permanent, measurable and technically demonstrable reduction of emissions, through increased energy production from renewable sources, the implementation of energy efficiency measures and the establishment of storage capacity and flexible operation of the energy system. The following are considered to be measures to reduce emissions: 1) reconstruction, revitalization and modernization, major repairs, investment maintenance, construction, expansion or replacement of capacities for the production of electricity or heat from renewable sources, including solar power plants, wind power plants, hydroelectric power plants, biomass power plants and geothermal power plants; 2) construction of new and improvement of existing energy storage systems, including battery systems, thermal, electrochemical or hydrogen storage, reversible hydroelectric power plants, as well as other technical solutions that contribute to the flexibility and stability of the energy system; 3) financing the construction of missing infrastructure (transmission and distribution grids, including substations and connection and distribution facilities), to the extent that such infrastructure is necessary for the connection, integration and increase in the share of capacity from renewable energy sources (including hydropower capacity) and associated storage systems; 4) measures to improve the flexibility of the electricity system in the function of integrating renewable energy sources, including balancing facilities, peak load management and the application of advanced management systems; 5) decarbonization measures related to the withdrawal of thermal energy capacities in terms of conservation or closure of facilities. For the purposes of calculating the tax credit in a given tax period, investments in a specific tax period and in those emission reduction measures whose implementation takes place over a longer period than the given tax period are taken into account and may also relate to emission reduction measures that began before the entry into force of this Decree.
Investments recognized for tax credit also include the preparation of project and technical documentation, the procurement of services or works related to the implementation of the emission reduction measure.
