Description
The main objective of the project is to increase the capacity for the supply of renewable energy in the Iosia-South neighborhood, having as its source geothermal energy. Other objectives is to reduce CO2 emissions, create new high skilled jobs and increase the amount of thermal energy produced from renewable sources.
The technical solution envisages the realization of a geothermal station in three stages of thermal energy production. The geothermal station will ensure the preparation of the thermal agent for supplying consumers, mainly from the geothermal source. By implementing the proposed solution, it will be possible to ensure an exploitation of the geothermal resource continuously, in the hot season, but also in the cold season, by using the geothermal resource to provide heating and hot water consumption.
It is necessary to increase the share of thermal energy produced from renewable sources within district heating system. This need is the responsibility of the Oradea City Hall and derives from national commitments to align with EU requirements. Following the implementation of the project, there will be an increase in the annual amount of thermal energy from geothermal sources, an annual reduction of CO2 emissions into the atmosphere with an estimated CO2 reduction of 42.794 tonnes during the commercial operation period of the project.
Expected outcomes are therefore:
- Increase the energy security supply of energy and implicitly of CO2 emissions and costs.
- Increase the standard of living for the population of the South-Iosia neighborhood by increasing the quality of public services.
- Increase of investment in the local area, new work for construction companies locally which can indirectly lead to an increase of need for local work force.
- A reduction in the subsidy granted by the Municipality to the thermal energy supplier, the funds being made available together with the resulting royalties to promote new investments at the level of the City Hall.
Summary of project results
The project aimed to address these main challenges:
1. Underutilization of Geothermal Resources: Geothermal water capacities at existing wells were not being fully used, presenting an opportunity to increase the flow of geothermal water for district heating systems in the Iosia-South neighborhood.
2. Reduction of Greenhouse Emissions: The project sought to reduce CO2 emissions from fossil fuel combustion plants by increasing the share of thermal energy produced from geothermal renewable sources.
The project involved the following key activities and outputs:
1. Development of a Geothermal Station: The project included the construction of a geothermal station in three stages of thermal energy production. The station would produce thermal energy from the geothermal agent using heat exchangers and heat pumps, and for peak loads, additional energy input from the District Heating System (DHS) transmission network.
2. Installation of Thermal Networks: The project required the installation of thermal networks to connect the geothermal station with the district heating system and neighboring buildings.
The project achieved significant results for various beneficiaries:
1. Increased Renewable Energy Supply: The project increased the annual amount of thermal energy from geothermal sources, with an estimated annual production of 15,010 MWh.
2. Reduction in CO2 Emissions: The project led to an annual reduction of CO2 emissions by 3,356 tonnes, contributing to a total estimated CO2 reduction of 42,794 tonnes during the commercial operation period.
3. Improved Quality of Life: The project improved the standard of living for the population of the South-Iosia neighborhood by increasing the quality of public services and energy security.
4. Economic Benefits: The project stimulated local investment, creating new work opportunities for construction companies and increasing the demand for local workforce. Additionally, it reduced the subsidy granted by the Municipality to the thermal energy supplier, freeing up funds for new investments.
