Development of heat supply and cooling systems in Latvia

Development of heat supply and cooling systems in Latvia

Currently in Latvia consumers heat supply is provided through centralized heat supply systems, local heat supply and individual heat supply. Directive 2012/27/EU of the European Parliament and of the Council defines “efficient heating and cooling”. The heating and cooling in the Latvian energy sector should be considered as a system consisting of three main elements – source, networks and consumers. The way this system works and works effectively can be based on the energy efficiency of the system elements. A low level of energy efficiency creates both energy security and resource sustainability as well as competitiveness risks. Increasing the energy efficiency level in the system as a whole, or individual elements of the system, will promote the growth of the energy sector while promoting to economic growth.

The main aspects that will be addressed in the planned research and implementation of the project are closely linked to the aspects identified in the Package of the Energy Union in order to promote energy development of a sustainable, modern, competitive and would be in the public interest in Latvia.

The project aims to implement a set of project tasks that include the determination of the potential of heat supply and cooling in Latvia, determination of the development potential of a centralized heat supply system, assessment of the heat market regulation regime, the mapping of heat density and long-term policy recommendations. Research tasks will be implemented using research methods such as scientific literature analysis, data analysis, system dynamic modelling and multi-criteria analysis.

Aim of the project: Determination of the energy efficiency potential of heat supply and cooling in Latvia and development of recommendations by 2030 with a perspective up to 2050. Assessment of the development potential of district heating and assessment of the heat market regulation regime. Policy recommendations for improving the efficiency of heat supply and cooling in Latvia, including efficient use of heat waste in industry.
