Capacity Requirements for the Gas Transmission System in Northern and Southern Moravia

Michal Kocůrek, Josef Dohnal

Summary: The contribution is based on a study drawn up by EGÚ Brno a.s. for NET4GAS, s.r.o., the exclusive transmission system operator in the Czech Republic. In general, the transit system and the national transmission system have sufficient capacities for supplying the domestic zone. However, the preceding years have repeatedly seen insufficient capacity in the region that is commonly referred to as northern Moravia on some winter days when gas demand was higher. One-time measures in the field, applied by the control rooms, helped to tackle such situations but, going forward, systemic solutions capable of coping with the potential increase in gas demand in that region will have to be adopted.

Pumped-storage Power Stations, Batteries, and Gas Storage Facilities for Ensuring Electricity Supply in the EU in 2030

Zuzana Benešová

Summary: The contribution summarises the outcomes from several studies drawn up by the European Commission and some European bodies specialised in energy, concerning the future European energy mix and the power generation system’s need for flexibility in 2030. It primarily discusses the impact of the growing share of solar and wind energy on electricity supply flexibility and the options for ensuring this flexibility. The contribution places special emphasis on the role of gas storage facilities and outlines the conclusions of the recently published study of their benefits for the power generating system. Because of the nature of the studies, the contribution focuses on impacts on the energy system of the European Union as a whole.
