1. Drilling, Completion and Testing of Geothermal Wells Convener : Pierre Ungemach (France) The course materials will focus on the techniques that could minimize the exploration drilling risk at the development phase of the project. Discussions will include various strategies to develop efficient and effective total project development work including well drilling, completion and testing that can be applied for all geothermal systems including steam, two phase and hot water dominated. 2. Design, Construction and Operation of Geothermal Power Plants Convener : Richard Campbell (USA) Geothermal fluids can be divided into at least two (2) groups, high temperature (>230°C) and low-moderate temperature (100 to <230°C). In this course, the conversion of geothermal fluids to electricity will be discussed: for a high temperature system, condensing turbine is used, while for low-moderate temperature systems the binary plant is preferred. Special emphasis in this course will be on principle selection of the turbine characteristics including turbine type, method of choosing optimal inlet pressure and optimal size and other specific applications such as cooling systems and operation & maintenance of each turbine types. 3. Geothermal Heat Pumps Convener : Prof. John Lund (USA) The highest growth rate in geothermal development is with geothermal heat pumps (GHP), one of the fastest growing renewable energy technologies. GHPs provide space heating, cooling and also domestic hot water. They can be installed also in dry ground. This idea is more valuable when the oil price increases. In this course, the principles and applications of the technology is taught completed with case studies. 4. Geothermal Project Financing Convener : Prof. Gordon Bloomquist (USA) The discussion of this topic begins with the development strategy layout, developing the work program and budget, followed by economics evaluation using optimum known assumptions and conducting sensitivity analysis on IRR versus price, pay out time and Net Present Value (NPV). Basically, a geothermal project is eligible to obtain carbon emission reduction (CER) credits under the clean development mechanism (CDM). Principle and procedure of CDM application and calculation for emission baseline of the tie-in electricity grid in order to obtain the optimal CER estimation and the economics of CDM revenue to the project will also be discussed in this course. The calculation can be divided into three development schemes, namely: up-stream, down-stream and total project development. 5. Introduction to Geothermal Energy Conveners : Sayogi Sudarman and Dr. Yunus Daud (Indonesia) Basic knowledge and technology involved in geothermal energy business process will be covered in this course, starting form preliminary survey, exploration, feasibility study, development and production, utilization of geothermal fluids, project economic evaluation and finally project operation management throughout the 30 year life span of the geothermal power projects. The course will also discuss prevailing regulations relating to geothermal business activities in Indonesia and compliance to safety and environmental standards. This special course is intended for capacity building of regional authorities who are involved in geothermal projects for direct use as well as electricity generation.
Subjects
Covers geological setting and their typical reservoir models, geothermal types, exploration methods and technologies mostly used for detecting reservoir parameters and characteristics that may impact to : drilling risk, development strategy, investment and O&M cost at pre-production and during production period, eg. reservoir changes monitoring.
Covers engineering methods and technologies used in up-stream and down-stream development. At the upstream side, it will cover drilling, well testing and production facilities, reservoir management including production and re-injection strategy. At the down stream side, it will cover various types of conversion cycle, geothermal power plant facilities. The course will also provide estimates about investment cost for upstream and down stream development, as well as for operation and maintenance (O&M).
Day Two (3 Subjects)
2. Geothermal Economics by Agus Danar Focusing on principal pricing evaluation (steam, power, generation cost and electricity tariff for total project development) and power purchase agreement concept, e.g. terms and conditions. 3. Environmental by Adiatma Sardjito Analysis local impact during pre-production incl. land clearance, social-culture change and during production period including community development and corporate social responsibility. * For the reason that Short Course 1 - 4 will be held at the same time.

SHORT COURSE 4 (SC4): GEOTHERMAL PROJECT FINANCING (General Agenda) Convener : Prof. Gordon Bloomquist (USA) How do you cross the financial desert of geothermal project development and reach the oasis of successful commercial operation and a secure cash flow? Geothermal Electricity Projects Require you to pay in advance for almost all the fuel supply for the whole life of the project before you can begin producing electricity. This leads to a high level of up-front capital investment. Greenfield Development Projects Progress through an exploration phase (geoscientific and exploration drilling), an appraisal and major funding phase (culminating in financial Closure), a construction phase (culminating in Commercial Operation) and an operational phase. Risks are high in the early phases but reduce as the project proceeds and certainty around the size and quality of the geothermal resource is achieved. Cumulative Development Costs Are in the range US$ 4 to 7 Million per MW, depending on the size of the development and other location and resource specific factors. For a 50MW development this means a totoal cost in the range US$ 200 to 350 Million. Most developers do not have the funds to cover 100% of this investment and so they must seek external financing. Funding sources include bilateral, multilateral and project financing, depending on whether the developer is a sovereign entity or an independent power producer. This course will present and discuss: 1. The costs and the timing of greenfield geothermal developments 2. The role of financing in providing funds to cover these costs (including Project Finance 101) 3. The investment returns expected by developers and financiers 4. The sources of funding available and the conditions that accompany these 5. The supports required to give investors "comfort" (tariff, Sovereign Guarantee, insurance) 6. the legal structures needed to support bankable projects 7. The impact of a cost on carbon or a value on carbon emissions reductions |
