Projects
During its 39 years of operation, Enex has participated in numerous geothermal projects worldwide. Below is a brief description of some of the most recent projects and customers.
Berlin, El Salvador, ORC Power Plant (LaGeo)
|
Salvadoran geothermal company LaGeo awarded an engineering, procurement, construction and management contract to Enex. The project includes a 9.3 MWe (gross) expansion to La Geo´s existing 56 MWe Berlin power plant, bringing the total installed capacity to 65.3 MWe. |
Geretsried-Nord, Germany, Binary Power Plant
|
Preparation for drilling is underway for a geothermal power plant in the Geretsried area. The world financial crisis has delayed drilling works for the project. In addition, further geological studies are in progress, such as 3D seismic, which will take place in late 2009 in order to start drilling in mid 2010. Geysir Europe, owns Enex Power Germany and Enex-Deutschland GmbH & Co. KG, that holds several research permits in the area around München and one in the Rhein Valley. » more |
Xianyang, China, Geothermal District Heating System
|
Enex Kina ehf and Sinopec Star formed a joint venture Shaanxi Green Energy Geothermal Development Co. The first project of the JV company was the construction of a geothermal district heating (DH) system in the city of Xianyang in Shaanxi Province, China. |
Slovakia, Feasibility Studies, Geothermal District Heating
|
Enex and its precursors have a fairly long history in Slovakia since the country has one of the best potential for utilizing geothermal heat in Central and Eastern Europe. Experts from Enex and their Icelandic partners, are working with Slovakian municipalities and local geologists to take advantage of the geothermal energy for central heating and possible electrical generation. Enex has in cooperation with Slovak towns established Slovak-Icelandic companies, in which five companies, three of which are from Iceland, are represented. The company is also a participant in the consulting company Slovgeoterm a.s., which specializes in advisory services relating to projects in the sphere of geothermal utilization. |
Galanta, Slovakia (NEFCO)
|
Galanta is small town of about 35,000 inhabitants 50 km east of Bratislava. The geothermal water is mildly mineralized and suitable for direct use. As a contractor of the municipality, the Slovakian Gas Co. and NEFCO, Enex successfully undertook the project of replacing lignite heating system of 1200 households with geothermal heating and solve scaling problems due to the water mineralization. |
|
Hungary (ALTENER II - EU)
Enex was a leading participant in a European Commission project under the Altener Programme framework regarding “Feasibility Study on Installing Mini-power Plants in Hungary”. Partnering with Enex hf were four Hungarian companies, one Austrian and one from Portugal. Project Coordinator is Geonardo Ltd., Hungary.
The project aim is to develop an integrated feasibility study on installing small scale geothermal power plants in Hungary combined by heating and balneological use through cascading system, providing a model for extended application throughout the Accession Countries and the EU-15.
Reykjanes Geothermal Power Plant
|
The Reykjanes Geothermal Power Plant is located on the Reykjanes peninsula in Iceland. The plant uses steam from a reservoir which at a 290 to 320 °C temperature. This is the first time that geothermal steam of such high temperature has been used for electrical generation. It can therefore be said that this is a pioneer project in the world geothermal industry. The Reykjanes Power Plant produces 100 MWe from two 50 MWe turbines. Owner is HS Orka, geothermal utility company. Additional 50 MWe is in the pipeline with the required steam already secured from new wells drilled in 2008 and 2009. |
Zakopane, Poland (World Bank)
Enex worked as a consultant to the World Bank on restructuring the Geotermia Podhalanska geothermal power plant in Zakopane Poland. The main task was to advice on technical, economical and managerial issues regarding the power plant and the company, as well as producing an input for the company new business plan. Enex is responsible for evaluating the old business plan, and preliminary ideas of the new business plan and its final version. The final report is crucial for the Bank’s further activities in the context of this project.
Beijing, China
|
Beijing City is situated on top of a large and deep sedimentary basin where geothermal resources have been found at depth. These resources owe their existence to sufficient permeability at great depth (1-4 km) where the rocks are hot enough to heat water to exploitable temperatures. Enex in cooperation with Tianyin Geothermal Development Co., Ltd. in Beijing, prepared a Feasibility Study for a geothermal heating system in Lishuiqiao in northern Beijing and will develop a Conceptual Design for a Geothermal heating system for a new housing complex of 450,000 m2 housing. Additionally Enex will establish a comprehensive Reservoir Simulation Model for the area using existing geological data and information from existing wells in the area. |

Budapest, Hungary (Fötáv)
Enex worked with Fötáv, the Budapest Municipal District Heating Authority, which operates an extensive fossil fuelled district heating network for the City of Budapest. The Budapest City Authorities are interested in meeting heating market expansion partly or wholly through the utilisation of geothermal energy and thus alleviate atmospheric and other associated pollution through the replacement of otherwise required fossil fuel. This they envisage achieving by integrating geothermal hot water utilisation with the already existing heating network.
Tanggu, China (NIB & NDF)
Enex worked with TGO (Tanggu Geothermal Office) to modify the existing geothermal system and design and erect an extension for 200,000 m² geothermal space heating according to current Nordic practices. Enex also undertook the responsibility of training people for operating the system as well as to evaluate the potential of the geothermal reservoir in the area.
The project was partly financed with loans from the Nordic Bank (NIB) and from the Nordic Development Fund (NDF).
Tengchong, Yunnan, China
To meet the urgent need for more electrical energy in Tengchong County and in answer to the ever increasing national and international emphasis on the use of environmentally benign energy sources, the Provincial Government of Yunnan established the Yunnan Geothermal Development Company Ltd (YGDC). This company drilled two production wells in the Rehai geothermal area in Tengchong, Yunnan. The wells are around 2.000 m deep and the temperature is around 180°C.
Enex made a feasibility study for the first stage of a geothermal power station to be erected in Tengchong with the production of 10 MW of electricity.
Enex recommended the geothermal reservoir monitoring and simulation methodology best suited to appraise the Tengchong geothermal reservoir’s production capacity and to enable the forecasting of its response to long term geothermal fluid extraction.
