A comprehensive analysis of technological developments in energy decentralization was prepared by researchers at the Technology Center Prague.
The analysis shows that decentralization is one of the main trends of the current energy transformation. Decentralization is developing thanks to the connection of three key processes: decarbonization, digitalization, and democratization of energy systems. Together, these move the energy sector towards local, flexible, and multi-level managed structures, in which households, municipalities, and businesses are actively involved.
The study shows that successful decentralization is a complex process combining technology, legislation, investments, and the active role of local actors. Thanks to current legislative and subsidy steps, the Czech Republic has a real chance to use decentralization not only for decarbonization, but also for strengthening energy self-sufficiency, regional prosperity, and social cohesion.
Main findings:
The study confirms that community and shared energy in the Czech Republic is rapidly moving from pilot projects to real practice. The key role is played by the amendment of the Energy Act (Lex OZE III), which introduces the European RED II and IEMD directives and clearly defines the rights and obligations of community entities.
The technological basis of decentralization is energy storage and network flexibility. The development of advanced batteries (Na-ion, flow, solid-state), alternative storage (LAES, Carnot), and digital platforms for flexibility management (VPP, DR, V2X) is developing. These technologies enable the effective integration of renewable sources, reduce congestion in distribution networks, and increase energy security.
The development of decentralized RES is based on the diversification of technologies – from new photovoltaics aplications to hybrid Power-to-X systems.
Digitalization and intelligent management form the basic platform of modern energy infrastructure. AI, digital twins, IoT, edge computing enable efficient operation, demand optimization, and increase the efficiency of data management. At the same time, growing digitalization increases the importance of cybersecurity, which is becoming a strategic element of the reliability of energy systems. The emphasis is shifting towards proactive and self-healing architectures.
The transformation also requires strengthening resilience and sustainability. Decentralization requires infrastructure modernization, network stability management, and the development of a circular economy – especially in the areas of battery recycling, critical raw materials utilization, and component reuse.
The report also formulated recommendations on how technological innovations, regulatory frameworks, and investment instruments can jointly contribute to an efficient and fair energy transformation of the Czech Republic.
