The analysis of portfolio management methodologies, the state of the population security systems and the strategy of reforming the system of the State Service of Ukraine for Emergency Situations has been carried out. The expedi-ency of realization of portfolios of projects of territorial fire and rescue units development is substantiated. The necessi-ty of developing the methodology of system-value management of portfolio of projects dealing with development of territorial fire-rescue units is substantiated. The system-value approach to portfolio management of the development of territorial fire and rescue formations development is proposed. It involves disclosing the synergetic essence of the value of these portfolios. The value is formed in stages on several levels of consideration of these portfolios and is condi-tioned by the peculiarities of projects and their changing design environment. The system approach to the structuring of the portfolios of the development projects of territorial fire and rescue units made it possible to establish their main components and peculiarities of the formation of the final product. It is substantiated that portfolios of development projects of territorial fire and rescue units are implemented on three levels – the united territorial communities, regional and state. The number and type of projects at each of these levels depends on the peculiarities of the project environment and regional development strategies. The results of investigation prove that the final product of the regional portfolio of projects for the development of territorial fire and rescue units and its system value is formed gradually by cre-ating separate security systems. Each of these systems has two types of specific subsystems - the subsystem "project" and the subsystem "product". The expediency of the development of scientific and methodical principles, models and methods for qualitative profiling of the mission and effective management of the architecture of the development port-folios of territorial fire and rescue units was substantiated.
