Another training of DHS operators in Latvia
The second in a series of capacity-building workshops for district heating system (DHS) operators, organised by KeepWarm's Latvian partner Zemgale Regional Energy Agency (ZREA), took place in Ozolnieki county and Jelgava city, in Latvia on 13-15 November 2018. The 3-day training was attended by selected national pilot DHS operators, DHS employees, some academics, energy experts and other interested stakeholders. The event was a mixture of theoretical input and field trips combined with real life examples, which was highly appreciated by the 20 participants.
The trainings in the countries KeepWarm is mainly active in (Austria, Croatia, Czech Republic, Latvia, Serbia, Slovenia and Ukraine) are being organised after an initial needs assessment carried out with national DHS operators and other stakeholders. After a first training for Latvian stakeholders focused on the use of renewable energy sources, waste and excess heat, the topics covered this time were more technical and included:
- Evaluating energy losses in the grid and identifying actions in order to improve and make smart grid. Remote measurement system, measurement standard;
- Modelling of heat supply systems after improving the energy efficiency of related buildings, specificity of the operating conditions of low temperature heating systems;
- Boiler house automation/optimisation of substation and heat storage;
- Optimisation of flow and recovery temperatures for DHS and cooling;
- Use of tools based on the Geographic Information System (assessment of heat demand, development of district heating network, mapping of surplus heat sources);
- Analysis of DHS operational data and analysis of DHS indicators for the transition to a fourth generation centralised heat supply system.
The presentations by high-level professionals were complemented by 3 study visits to the following places: POLIURS Ltd. (manufacturer of industrially isolated pipes), Ozolnieki KSDU Ltd. (district heating provider in Ozolnieki county) and Fortum Jelgava, Ltd. (district heating provider in Jelgava city).
The next training workshop in Latvia in the framework of the KeepWarm project is planned at the end of January 2019. It will be focused on organisational or financial issues, depending on the availability of presenters.
