Funded by the “Program for Energy in Romania”, Area of interest Renewable Energy, Call for Projects – Call 2 – Increased capacity for the supply of renewable energy – Geothermal energy.
The “Program for Energy in Romania” is financed by the EEA and Norway Financial Mechanisms, 2014-2021. The program contributes to the achievement of the general objectives provided by the EEA and Norwegian grants for the period 2014-2021, respectively to the reduction of economic and social discrepancies in the European Economic Area (EEA) and to the strengthening of bilateral relations between the EEA States and the beneficiary States of the EEA and Norwegian grants.
The program intends to stimulate and develop long-term collaborative relationships between Iceland, Liechtenstein, Norway (referred as “Donor States”) and Romania, encouraging bilateral partnerships aimed at project development.
The purpose of the project is to increase the use of local renewable geothermal energy resources for the preparation of the thermal heating agent and tap water for consumption, as well as by creating new thermal energy production capacities in the Centralized Thermal Energy Supply System (SACET) of Oradea.
The direct beneficiaries of the investment are the approximately 4,800 residents of the Ceyrat neighborhood, respectively a total of 1,600 apartments, as well as the new Multipurpose Hall (5,000 seats) – Oradea Arena.
The main element of energy efficiency of the project is given by the use of heat pumps that allow the recovery of additional heat from the geothermal water. By using heat pumps and re-injecting the used water back into the reservoir, the sustainability of the resource utilization will be ensured, and the energy stored in the geothermal water will be efficiently exploited. At the same time, in order to ensure all the energy needed by the neighboring buildings during the peak period, the energy input from the City’s Heating System Network will be used.
The project “Best usage of geotermal water” is located in the south-eastern part of the municipality of Oradea, in the area bounded by the streets Vlădeasa, Făgărașului, Traian Blajovici, Islazului, Ceyrat and Peta stream.
The intention of the municipality is to ensure the provision of a good quality heating service through the appropriate use of geothermal water resources, to reduce pollution and to stimulate the development of the local economy, being doubled by the opportunities offered by the non-refundable financing programs, in the present case , EEA and Norway financial mechanisms, 2014-2021, “Program for energy in Romania”, Calls for Project Proposals, Area of interest: Renewable energy.

Partner in project implementation is the Icelandic company Mannvit hf. This is an international consulting firm in the fields of engineering, technical services and innovation. They make an important contribution to the project by transferring know-how in the specific field of geothermal energy use and by evaluating the test results from the geothermal water extraction well no. 4796, used in the project.
The main objective of the project is to increase the renewable energy supply capacity, with geothermal energy as the source.
Construction of a building on the metal structure and installation of equipment for operation based on geothermal water in three steps (total capacity 25.4 MWt) on Fagarașului Street near the site of the new Multipurpose Hall – Oradea Arena.
The first stage heating agent production plant has the following configuration:
– Stage 1: Production of “Primary Geothermal Thermal Agent” of 84°C
The geothermal energy, which comes from the production well no. 4796 existing, is transported through an adduction connection to the Geothermal Thermal Station (STG). The energy will be extracted from the thermal water and will be cooled from the extraction temperature of 84°C with the help of heat exchangers to a temperature of approx. 40°C. The thermal agent produced at 82°C will ensure the supply of consumers with the thermal energy required for domestic hot water and heating in basic and medium mode approx. 3800 – 4000 hours annually.
The thermal load in step 1 will be approx. 5.1 MWt
In order to ensure the peak thermal load in the cold season, for the previously mentioned objectives, it is proposed to connect the geothermal station to the transport network of SACET through a link that will ensure the energy required for the operation of the third stage of the STG.
The chosen solution ensures a safe supply of consumers through the existence of a double production possibility for the primary thermal agent (estimated lenght L=1072m).
The thermal energy existing in the geothermal water cooled in stage 1 to a minimum of 40°C will be further used to obtain a complementary heating agent using high temperature industrial heat pumps. The additional thermal agent produced in the heat pumps at a temperature of 85°C together with the one in stage 1 will ensure the supply of the consumers with the necessary thermal energy in the average load regime approx. 3000 hours annually.
The thermal load in stage 2 taken from the geothermal water will be approx. 3 MWt.
For the evacuation of the used geothermal water from the heat pumps (approx. 20 gr. C), an evacuation connection to the reinjection probe F2 in the Ceyrat neighborhood is provided. For the evacuation of a possible surplus of used geothermal water or for a case of force majeure, the connection to the city’s sewage network is provided.
For the summer, peak regime and for cases of force majeure, the necessary energy will be taken from the SACET transport network, using primary agent produced by high-efficiency cogeneration in the city’s Electro Thermal Power Plant.
Stage 3 of the STG will be equipped with equipment for taking thermal energy from the SACET primary network.
Main thermal energy recovery equipment:
– primary heating agent circulation pump from the SACET network, stage III
– mixing cylinder for the thermal agent
The thermal power taken from SACET in stage III is 17.34 MWt
An electrical connection to the electrical power distribution network is required for the operation of the STG in a three-step heat production regime. This connection will have to ensure the electricity required for the operation of the technological installations for the production and distribution of thermal energy to consumers. The main electricity consumers installed in STG are:
– electric pumps for the circulation of thermal energy
– the heat pumps in stage II of thermal energy production
– other consumers that ensure the operation of STG installations
At the border of the STG, a transformation station and a power station will be installed to supply electricity to consumers.
The power installed in the power station is 1600 kVA for heat pumps
Realization of the network for heat transport from STG to the block district on Ceyrat Street and to the Polyvalent Hall on Traian Blajovici Street. The supply of thermal energy produced in STG will be ensured through thermal energy transport networks. These networks will ensure the connection between STG and the thermal points located in the consumers’ buildings (estimated lenght L=1.53Km). In these thermal points of the consumers, heat will be transferred to the indoor heating installations and hot water for consumption.
