„Exploitation of geothermal energy in combination with primary thermal agent for the production of thermal agent for heating and hot water in Oradea Ioșia – South District”

PROJECT
COMPLETED

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 objective of the Program: “Energy with low carbon emissions and greater security in supply”.

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 consumers connected to the thermal points 910 (Fagurelui Street), 911 (Nicolae Bolcaș Street) and 913 (Aleea Călinului Street), respectively 1.853 apartments that will benefit from heating and hot water produced from the renewable resource of geothermal water.

The technical solution of the project consists in extracting the geothermal water (with a temperature of 85°C) from the two production wells, directing it through pre-insulated pipes to the Geothermal Thermal Station (GTS – Oneștilor). In the GTS the heat will be transferred to the thermal agent (for heating and hot water) through heat exchangers and heat pumps. After the heat is released, the geothermal thermal waste water will be discharged into the outfall (Peța stream) or the municipal storm sewer network at a temperature of approx. 20°C.

The project is divided into 5 objectives as follows

Objective 1 : Geothermal Thermal Station (GTS) including Stage I equipment, automation system, data transmission system

Refurbishment of the building of the thermal point 516 near the West Printing House (currently disused) and equipping it with equipment for the extraction of thermal energy from the geothermal water network for distribution to the primary network for the supply of thermal energy to consumers (PT 910, PT 911, PT 913).

Capacities installed in STG:

total thermal capacity of the STG is 16,085 MW
thermal capacity extracted from geothermal water in stage I is 5,795 MW
thermal capacity extracted from geothermal water with heat pumps in stage II is 3,7 MW

Objective 2 : Geothermal network from existing geothermal wells to the geothermal thermal station

Installation of the thermal network for geothermal water, which will be connected to the two geothermal wells.

The thermally used geothermal waste water from the Geothermal Station will be discharged into the Peța Creek through a pressurized discharge pipe. A discharge connection to the municipal storm sewer system will also be provided.

Geothermal water piping will be connected to:

Well 4005 located on Calea Aradului respectively to the existing geothermal water pipe on the Peța bank (currently supplying thermal point 913), near the road bridge on Calea Aradului.
Well 1720 located in the south-eastern part of the municipality of Oradea, at the entrance to the commune of Sântandrei. A pre-insulated steel pipe will be installed underground between the well connection point and the road bridge on Calea Aradului.
The point of connection of the two pipelines from the wells, respectively the road bridge on Calea Aradului and STG Oneștilor.

Objective 3 : The connection between the geothermal thermal station and the district heating network on Onestilor Street, including the stage III necessary for the heat energy supply from SACET

Making a primary thermal agent transportation connection from the primary thermal network located on Oneștilor Street to the STG and connection to the primary thermal agent transportation network of the STG for supplying consumers.

Objective 4. Stage II a (STG) consisting of heat pumps

The Geothermal Station will be equipped with equipment for taking thermal energy from the geothermal network and distributing it to the primary network supplying thermal energy to consumers.

Equipment for geothermal thermal energy extraction in Stage II:

heat pump for heat extraction from geothermal water
plate heat exchanger for heat transfer from the heat pump

Objective 5: STG electricity supply connection

An electrical connection to the electricity distribution network is required for the operation of the GTS in three-stage heat production mode. This connection will have to provide the electricity necessary for the operation of the technological installations for the production and distribution of thermal energy to the consumers.

The main electricity consumers installed in the STG are:
