Status of Geothermal Development
in Menengai, Baringo-Silali Projects

GDC has developed 572 MWe of steam in both the Olkaria and Menengai Geothermal Projects. In the Olkaria Project, GDC is currently selling 320MW of steam to Kenya Electricity Generating Company (KenGen) earning an aggregate sum of USD 30 million, in annual steam sales revenue.

A total of 167 MWe of steam is currently available with the steam gathering system nearing its completion at 95%. Additionally, 105 MWe has been set aside for the setting up of three (3) power plants of 35MW each, to be carried out by three Independent Power Producers (IPPs); QPEA GT Menengai Limited (QPEA), Sosian Menengai Geothermal Power Limited (SMGPL) and Orpower 22 Limited (OTT).

The first phase of the 300MWe Baringo-Silali Geothermal project is underway, with over 100 kilometres of access road completed and a water reticulation system at eighty percent (80%) complete. Thereafter, exploration and appraisal drilling of 15 to 20 wells will be carried out, followed by a feasibility study in preparation for production drilling.

Sigurður St. Arnalds
Geothermal Sustainability Assessment Protocol (GSAP)

In 2016 three Icelandic Power Companies and two Governmental Agencies formed a Working Group for the development of an assessment tool to measure geothermal sustainability performance; Geothermal Sustainability Assessment Protocol, GSAP. Background: The International Hydropower Association, IHA, introduced in 2010 a multi stakeholder Sustainability Assessment Protocol, HSAP, now applied worldwide, to assess key sustainability factors of Projects, social, environmental and economic. Representatives from IHA, Governments, Finance and NGOs prepared the Protocol. The aim is to measure, guide and improve performance for sustainability topics. Iceland actively participated in the preparation of HSAP. The GSAP Working Group took on to transform this widely accepted HSAP tool to geothermal application. Modifications are kept to a minimum to maintain as possible existing consensus. A Draft GSAP is now prepared and successfully tested for the Preparation Stage of Theistareykir 90 MWe and the Operation Stage of Hellisheidi 300 MWe /130 MWth.

JICA's Cooperation in Geothermal Development

Japan International Cooperation Agency (JICA) is the governmental organization which implements the ODA programs by the Japanese Government.  The operational scale of JICA, including yen loan, grant aid and technical cooperation, is approximately 15 billion JPY (FY2017).  The JICA’s support policy for energy development is “3L” policy (Low cost, Low carbon, and Low risk) and geothermal development is one of the main targets for the support.

While promotion of the geothermal development is a core of the contribution for the achievement of SDG 7 (universal access) and SDG 13 (climate action), it faces several challenges, namely mitigating resource risk, easing the burden of initial investment, and securing stable plant operation and cash flow.  JICA will support to overcome these issues by utilizing yen loan, grant aid, technical cooperation, and private sector windows.

Ownership structure and its effects

The cost of operating and maintaining geothermal power plants is a major factor in establishing the profitability of the project.

Geothermal power plants have various operating (and maintaining) costs which set them aside from conventional power plants. The presentation will analyze the different cost items let them be fixed or fluctuating. How can investors and lenders put a lid on such costs will be discussed as well.

Finally, there are various project finance structures that we use in the geothermal space: IPPs, BOT and Joint Ventures of all kinds. How to assure alignment of interests and optimal performance  under several structures will be the topics of the presentation.

Grid Stability offered by Geothermal

Modern society is very reliant on electricity. Electricity is an essential service that supports processes, production and standard of living in many ways. It needs to be resilient. There are substantial changes taking place in the electricity market and the requirements today for the system to be resilient are very different from 20 years ago. Changes in the market, often referred to as the disruption, and the global change with a focus on renewable energy calls for new approaches and the participation of all actors in the market. Geothermal power is around one third of the installed power in Iceland and has therefore a potential of improving the stability of the system. In my presentation, I will talk about what the challenges are in operating today’s power system in Iceland and what experience we have with co-operating with the geothermal power plants in improving system stability.

Industry leadership in setting best practice

The presentation will focus on the importance of gathering and centralizing information and documentation for the purposes of developing an understanding of how geothermal resources can best be developed. Furthermore, the presentation points out how such centralized databases can help governments understand how to attract investors and developers that are interested in exploring and exploiting geothermal resources. Such centralized databases will also assist countries in the important task of strengthening legal frameworks to secure national interests and the sustainable utilization of geothermal resources. Finally, it is of critical importance for the industry that developers must meet similar requirements and follow similar regulations in the different countries in which they intend to explore and/or develop geothermal resources. This can best be achieved with the gathering and public disclosure of information. Co-operation among industry leadership is necessary for such a centralized database to be achievable.

TGDC Power Plant Development

Tanzania is endowed with enormous geothermal resources which exist in the two arms of the Great East African Rift valley that transverse the country from north to south. The Government of Tanzania is determined to develop and utilize this sustainable domestic resource for generation of power and direct uses to support its fast-growing economy.

The presentation covers deliberate actions taken by them towards the development of the geothermal and harnessing the resource, particularly creation of the State Owned Entity (TGDC) for spearheading the geothermal resources development, establishment of enabling environment through formulation of appropriate legal and regulatory framework and streamlining the institution set up. In addition, the covers the status of selected geothermal flagship projects which are being implemented and mobilization of funds for test drilling. Finally, the presentation dwells on the establishment of essential local capacity both organizational and institutional that is required to support the geothermal development, exploitation and utilization.

Lessons learned from other industries

Geothermal power plants are well developed with many references around the world. However, globally there is less expertise with geothermal power plants than with coal, oil or gas fired power plants. To accelerate innovation and reduce design risk the expertise from these more mature industries can be partly transferred to geothermal, e.g. fouling, manufacturing and cycle design expertise.

ERK is active in the field of industrial and utility boilers and heaters since the 1940’s and has realised with its licensees more than 6,000 references worldwide and in various industries. The presentation will outline which concepts and technologies can be transferred to the geothermal area to lower plant cost, reduce project risk and enhance cycle efficiency. Some examples will illustrate these effects.

Reykjavik Energy
Reaching zero emissions with added environmental, social, and economic value

Twelve years ago, in year 2006, the idea behind CarbFix was born. Today, the CarbFix technology is operated at an industrial scale at The Hellisheidi Geothermal Power Plant, allowing for otherwise emitted CO2 to be captured and injected into basalt formations. There it is turned into rock in less than two years’ time and thereby permanently removed from the atmosphere.

In twelve years’ time, in 2030, Reykjavík Energy and subsidiaries will have fulfilled their ambitious climate goals of zero-emission power plants and a 60% smaller total carbon footprint. Dr. Aradóttir will explain how these environmental targets will be reached, concurrently adding fiscal and social value. Reykjavík Energy’s approach supports UN‘s Sustainable Development Goals. Incidentally, the deadline to meet them is also in the year 2030.

Managing Silica Deposits in Geothermal

Silica scale in geothermal is generally managed by either removing silica or pH modification to pH<5.0, using either CO2 or other mineral acids.  In addition to corrosion and safety concerns, pH-Mod can trigger the precipitation of some minerals that are less soluble in acidic conditions. The use of silica inhibitor GEO981 in the field prevented simultaneously, the deposition of both silica and stibnite resulting in reducing total operating cost, improving asset integrity and safety.

Turkish Geothermal Development – Zorlu Case Study

By the end of January 2018, Turkey entered into 1 GW country club with the capacity of 1.100 MWe. With regulations prepared in 2007 and 2008, Turkish geothermal capacity reached from 15 MWe to 1.100 MWe in recent 10 years. This presentation gives a brief information about triggering points for this great development in Turkey by taking into account the contribution of Zorlu Energy for the development of this business with best practices. The main point would be the construction and commissioning of the largest geothermal power plant of Turkey, Kızıldere-III that is the Ph. D. level of Zorlu Energy for geothermal power plant construction and commissioning, with 165 MWe capacity.

Binary power plants for the high enthalpy well-head generation

Binary Technology is globally recognized as a mature technology for power generation from various heat sources. Geothermal is one of the renewable sources of energy most suitable for binary application. The use of a binary fluid allows generation of electricity from very low-temperature liquid-dominated geothermal sources, to high enthalpy steam dominated resources.

While traditional flash steam power plants exploit only the steam fraction of the geothermal flows, binary can use also the liquid part in order to increase the specific utilization of the resource.

The paper will provide information about the advantages of using binary technology for well-head power generation, as compared to the traditional flash steam turbines.

NZ Geothermal Legislation:
The Resource Management Act.

Phoebe presents New Zealand’s legal framework for geothermal resources and explains the legal requirements and regulatory processes for geothermal resource development. Sustainable resource management and public participation in the creation of policy are key to New Zealand’s environmental law. Sustainable management is required through regional policy and rules, and regulatory processes support resource sustainability. Public participation occurs at strategic and operational levels, in the preparation of resource planning documents, and where resource permits are considered. Geothermal law and policy are examined in the context of sustainability and public participation, with reference to perceptions about public access to environmental information regarding energy resources and their use.

Geothermal Strategy in Djibouti


Djibouti is a relatively small country with a population of less than 1 M, but located in a key position in eastern Africa, in a close vicinity with Arabia, well deserved by marine routes of the Red Sea and Gulf of Aden, ensuring the link between the Mediterranean and the Indian Ocean parts of the world. It acts as the major port for its neighbour Ethiopia worth 100 M inhabitants.

In terms of energy, it has for long relied upon imported fuels. However, considering the global climate issue – hitting the region with increasing draughts – and despite its moderate contribution to Greenhouse Gas Emissions, the Government of Djibouti defined a “Vision 2035” in which an objective of 100% renewable energy production was defined. This implies to rely upon the various natural resources available including Wind, Solar and Geothermal.

The present meeting concerns this last sector, which is of major importance as Djibouti benefits from an exceptional location, at the intersection of the Gulf of Aden, Red Sea and East African Rift systems. This provides very high heat flow, with magmatic and hydrothermal manifestations at the surface indicating potential geothermal resources. However, despite geothermal exploration initiated more than 45 years ago, no production is yet available. This is the reason why the President of the Republic of Djibouti decided in 2014 to establish a specialized public entity called ODDEG (for Djiboutian Office for the Development of Geothermal Energy), which is hosting the present meeting.

Since ODDEG was created, it was staffed, provided with large office facilities and a significant budget. ODDEG developed a strategy, a pluri-annual work plan and a procedure manual. A data bank was also established with a description of more than 20 identified geothermal sites in Djibouti. Besides Djibouti’s state budget, ODDEG also benefited from the help of foreign donor agencies, particularly from Japan, Iceland, Germany and USA.

It was considered that, at present, besides the bilateral engagements, the time had come for ODDEG’s partners to meet and discuss future issues.


The purpose of this presentation is for ODDEG and the Government of Djibouti to inform representatives of the donor agencies on the progress in the establishment of the Office, in particular its strategy, work programme, and projects being engaged or considered as additional priority targets.

In the presentations the General Manager will also underline the strength and weaknesses of its staff and technical capabilities, in order to pinpoint where partner’s involvement would be the most appropriate (training and capacity building on site, laboratory equipment’s, engineer’s and PhD engagements abroad, etc…).

Iceland Deep Drilling Project
(IDDP-2): A better tomorrow

HS Orka, the third largest power company in Iceland, has been leading the IDDP2 project at Reykjanes. The main objectives of the project have been to drill deep enough into the roots of a conventional high temperature hydrothermal system to produce fluid at supercritical conditions. With this technology we hope to reduce our environmental footprint significantly.

Drilling started in August 2016 and was completed in January 2017 at 4,650 meters and the well is the deepest high temperature geothermal well ever drilled in the world. The drilling was very difficult and a lot of lessons learned during these months.

The presentation will show the challenges, the teamwork and what the status is today, aiming for a better tomorrow.

Overview of risk mitigation -
success stories

High risk related to discovering the geothermal resource at the early stages of development is recognized globally as one of the main obstacles to the advancement of geothermal energy. Risk mitigation mechanisms have been established in several countries to address this challenge. These provide financial support to developers with the aim of mobilizing private investment. In this presentation the advantages and disadvantages of the main risk mitigation mechanisms are analyzed and discussed. It is shown that depending on how the mechanism is implemented, its impact on risk can vary considerably. Higher impact is obtained by making the financial aid depend on the success of the drilling. By pooling several wells, impact can be increased further. Success stories in geothermal risk mitigation are discussed and it is argued that geothermal risk mitigation can be a cost effective way to reduce greenhouse gas emissions.

Geothermal reservoir management
and sustainable use

Production capacity of geothermal systems is controlled by the response of the systems to production, predominantly by reservoir pressure decline. A key issue in geothermal reservoir management is monitoring of the production response of a system. Based on the production response data, tools for reservoir management can be developed, such as numerical models to predict the future response of a system to different production schemes. Such reservoir management tools are important for both environmental and operational purposes.

Geothermal energy can play an important role in developing a sustainable energy mix in different energy markets. The sustainability of different geothermal utilization schemes can be confirmed by long term monitoring and modelling of the response to production of the geothermal systems in question.

Economics of a GeoMagma power plant

The Iceland Deep Drilling Project (IDDP) has been ongoing since 2000. The goal is to utilize very high-temperature geothermal reservoirs and produce power more efficiently through state of the art of geothermal power production. The high-temperature geothermal reservoirs concept is called GeoMagma within Statoil. Mannvit and Statoil have cooperated in establishing the plant design and economically viable ways of utilizing the heat to produce power for the GeoMagma concept. The knowledge that has been gained from the drilling of the first two IDDP wells and from the discharge of IDDP-1, both give indications on the challenges and gains which may be expected for such projects. Some of these challenges are discussed in the presentation and serve as the baseline for the design of the GeoMagma concept. Comparisons put forth include discussions on technology, costs, and risk.

Solid conceptual modeling

The geothermal resource is the biggest uncertainty in geothermal development. Collection and understanding of geoscientific data about the resource is the only way to reduce this risk. Conceptual modeling is the vehicle geothermalists use to assess the completeness and quality of the geoscientific data and for using the data to understand the resource and enable data-driven decision making, particularly in the early-stage development drilling decisions. This talk describes the components of a conceptual model, the data and expertise required to build the model, and how a conceptual model is constructed. Then, we will discuss how a conceptual model is to reduce risk in geothermal development; to assess the type and size of the resource and well targeting. Accurate resource assessment matches expectations, planning and financing of the geothermal project to the resource and well targeting using conceptual modeling improves the overall drilling success rate. Examples are presented.

Production and reinjection: Holistic approach

At Hellisheiði geothermal power plant, steam management and reinjection has been a challenge worth tackling. By setting a clear focus on effective resource management and innovative thinking, many of the challenges are on their way of being solved. Special focus has been set on understanding the relationship between reinjection and steam supply, as research and experience has shown that it plays a vital role in the long-term sustainability of the plant. Future plans for the power plant incorporate that knowledge into development strategies for both steam supply and reinjection to ensure successful operation in the times to come.

Strategy for fast development

The rapid growth of the geothermal Turkish market did not happen by itself. It is a combination of regulation, developers, technology and above all, collaboration. Furthermore, during the process of its development, we, as Ormat, as well as other participants in the process, has improved their process and approach.

In this presentation, we shall review the current status and the history to learn the changes in the developers’ approach and the regulations. An analysis of the process with some insight will follow. Lastly, a short look and self-perception on where the market is going to and what are the main obstacles that we see. To conclude I will try to make a reflection on the Icelandic market in view of the findings.

Competitiveness of the geothermal sector

Iceland has a relatively long history of geothermal energy use. Today, nearly all households in the country are heated using geothermal energy and geothermal energy has many different other direct uses. Also, use of geothermal energy to produce electricity has increased in the last decades.

We have analyzed the competitive position of geothermal energy, both worldwide, vis-a-vis other energy sources but our main focus of research is on the competitive position of Icelandic companies in the global geothermal market. Our results indicate that geothermal energy has not seen the same growth as other sustainable and environmentally friendly energy sectors, notably solar and wind. Also, we find that although Icelandic companies and institutions have a long history and good reputation, the competitive position is not as strong as might be expected. We conclude that this result may be due to the institutional framework of the sector.

Promoting sustainable heating and cooling in Europe and beyond.

For years, the heating and cooling sector, which accounts for roughly half of energy use in Europe today, was left on the sidelines of the EU policy debate. Recently, the issue has begun to move rapidly towards centre stage, a change that is inevitably bringing a series of changes, challenge and opportunities for the district heating and cooling industry.

This presentation is intended to give an overview of recent developments and summarize their practical implications for the sector. Finally, it will touch upon future prospects and identify steps which we can and should take as an industry to ensure that heating and cooling networks are in a position to deliver on their enormous potential to contribute to meeting climate and energy challenges in Europe and around the world.

The Corbetti & Tulu Moye Projects

In December of 2017, Reykjavik Geothermal along with its co-investors signed the Power Purchase Agreements and Implementation Agreements for its twin 500 MW geothermal power projects in Ethiopia, Corbetti and Tulu Moye. The projects are unprecedented in their scale: if fully developed through all phases, each project would be the largest IPP investment in Africa across all energy sources, and among the largest geothermal projects in the world. This presentation discusses the supply and demand dynamics that led Reykjavik Geothermal, its co-investors, and the Government of Ethiopia to jointly embark on this ambitious development, as well as presenting the status of the projects.

Lithium recovery from high temperature geothermal brines.

The growing demand for lithium has created an immense opportunity for its recovery from produced brines. Traditionally, lithium is recovered from mining or brine evaporation with the latter requiring vast evaporation ponds, months of processing time and has low recovery efficiency. Large strides have been made in the development of selective adsorbents for lithium and other metals but their use is constrained by competing ions that must be removed in pre-treatment. We have developed a combined water treatment and metal recovery technology that overcomes these challenges and can do can operate at temperatures up to 500 °C. The pre-treatment system relies on a unique ultrafiltration approach that promotes fouling of a replaceable skin layer. The layer itself is composed of highly charged materials that perform a coagulating function, enhancing the efficiency of the filtration system and making it a preferable option to the use of warm or hot lime softeners, after filters and other technologies typically seen in thermal industries. The system removes silica, magnesium, iron and other metals often to concentrations that are below method detection limits. Other scale forming ions such as calcium are reduced 40-70% to levels that do not interfere with lithium recovery. Lower concentrations are feasible but not required in our applications.  The selective ion-sieves developed for lithium recovery function in a similar fashion, capturing lithium within the crystalline structure of the ion sieve within a simple column design. I will review the technology, provide an overview of lithium recovery from brines and provide a summary of a geothermal project where we have proven the technology and are moving to commercial deployment in 2018.

Capturing CO2 from air

At the Hellisheidi power plant, Climeworks has partnered with Reykjavik Energy and ON to combine direct air capture (DAC) technology for the world’s first time with safe and permanent geological storage of CO 2. Low-grade geothermal heat is utilized to capture atmospheric CO2 with Climeworks’ technology. The captured CO2 is then dissolved in water and sent to more than 700 meters underground in collaboration with the CarbFix project. There, the CO2 reacts with the basaltic bedrock and forms solid minerals, creating a permanent storage solution. This project is a prime example of a novel and promising cascaded use of geothermal heat. Through the use of geothermal energy for DAC efficiency and economics of geothermal operations around the world can be increased and new future-proof markets in the field of CO2 utilization and –sequestration can be opened up.

Quantum Power

Quantum Power is private investment company developing power projects in sub-Saharan Africa. In a tender awarded by the Geothermal Development Company of Kenya in September 2013, Quantum was awarded one of three 35MW production concessions in the Menengai steam field located in Nakuru County, Kenya. In a market where even the simplest privately financed project finance transactions are complex, the tender and project structure was new for Africa with the Government sector and donor development financial institutions providing the upfront capital required to de-risk surface exploration, drilling risk and intending to shorten the time between exploration and production for private investors. There has been much speculation as to the success of the tender, the project structure and the projects progress. This presentation will therefore briefly present Quantum Powers experiences and progress with regards to its first geothermal project in Menengai.

Ethiopia is located in the Horn of Africa, central part of the East Africa Rift valley System. Ethiopia, due to its position crossed by East African Rift Valley System (EARS), exhibits all the conditions for the development of economically exploitable geothermal systems. Starting from the 70s, several geothermal prospects were studied at different levels of knowledge in relation to their characteristics.

About 23 sites are identified for potential geothermal resource development along with the Ethipian Rift Valley System. Despite the high geothermal potential of the Ethiopian Rift Valley system, only one site (Aluto Geothermal field with about 7.3 MW installed capacity) was developed in 1990s as a pilot geothermal power plant project. Studies conducted at various levels indicate that Ethiopia can develop more than 10,000MW from its abundantly available geothermal resources.

In fact, Ethiopia has also huge hydroelectric potential and currently its main energy source is from hydropower with some contribution from other sources (wind, diesel, bagas and geothermal). Recognizing the need for energy mix and diversify the energy source, the government gave due attention to develop the geothermal resource for electric generation and other direct uses to realize the country’s development goals.

Currently, the most interesting sites that are in an advanced development phase are: Aluto, Tendaho (Dubti), Tendaho (Alalobad) and Corbetti, Tulu Moye.

The first three are being developed by the GoE with the support of external financing agencies, while Corbetti and Tulu Moye geothermal sits are being developed by private sector under Independent Power Producer (IPP) scheme, for which Implementation Agreement and Power Purchase Agreements has been signed in December 2017.

Aluto and Alalobad geothermal fields are being developed under the Geothermal Sector Development Program (GSDP). The GSDP is designed to drill about 22 exploration and production wells to confirm the resource for generating electricity in the order of 70 MW at Aluto field and 4 exploration wells at Alalobad with aim of generating about 20 MW. The GSDP is funded by the World Bank (major financer), Government of Iceland and Government of Japan. The government of Japan is further considering for financing the power plant construction in two phases based the findings of the initial exploratory drilling operations at Aluto Geothermal field.

Collagen production

Codland´s mission is to develop valuable market driven products from underutilized parts of wild caught and sustainably harvested codfish. Many side streams from fish processing have traditionally been regarded as waste to be discarded or sold as low value products. The company was founded by two well-established fishing companies to optimize the valorisation of these by-products and to increase the value of each fish caught from the limited stocks around Iceland. The current main activity of Codland is setting up facilities to produce nutraceutical collagen peptides from fish skin in a joint venture with four of the biggest seafood producers in Iceland.

Social impact and economic benefits
of district heating

90% of Icelandic homes have geothermal district heating, with the remaining 10% heated with electricity produced from geothermal, wind or hydro energy sources. This is not only very environmentally friendly, but also has huge economical and social benefits. Perhaps surprisingly, the decision to provide geothermal district heating for Icelanders was controversial at the time, as it was an extremely complicated and expensive task. The presentation will tell the story of how a small nation took a risk and decided to utilize local sources for cheaper energy and more independence from oil, which has resulted in better living for everyone.

Theistareykir Power Plant - Phase I

The geothermal area at Theistareykir in the northeast of Iceland has great potential for geothermal utilization, with an estimated capacity of up to 200 MWe according to Environmental Impact Assessment published in 2010.

Preparation work and research on the sustainable utilization of geothermal energy at Theistareykir began in 1999 by an association founded by local municipalities and regional utility companies, later merged into Landsvirkjun. The objective was to harness the geothermal resource in a sustainable way.

Design for 2×45MWe power plant started late 2011 and the first tender for contracts was released in 2014. On-site construction started in June 2015 and from that time an ongoing construction and equipment installation.

Commissioning work started in middle of 2017, unit 1 started commercial operation in November 2017 and unit 2 in middle of April 2018.

Now, at the end of project execution time the predefined objectives of the plant´s function and power capacity has been met as well as the construction cost is according to budget and the planned time frame has been kept.

Maibarara Geothermal Inc.
Maibarara, Philippines

Immediately after the enactment of the Renewable Energy (RE) Law in 2008, following earlier government decisions deregulating the electricity industry, sixteen (16) geothermal areas were licensed between 2009-2010 for development to 13 different companies with an aggregate target installation capacity of 626 MW. Nearly ten years later, only 4 of the 16 sites saw new deep drilling by their respective investors. And of the 4 sites, only one – Maibarara in southern Luzon – was successfully developed by service contractor MGI to put into commercial operation a 20MW unit (Maibarara-1) in February 2014 and a 12 MW unit (Maibarara-2) in April 2018. The business and development decisions MGI made to become the only new geothermal power producer in the Philippines, alongside established giants like Energy Development Corp. (EDC), Phil. Geothermal Power Corp. (formerly Chevron Geothermal), and AP Renewable Inc. (APRI), are the subject of this talk.
