Analysis of Risk Mitigation Strategies
Government as Developer Cost-Shared Drilling Resource Risk Insurance Early Stage Fiscal Incentives
Government Acting as Developer:Introduction Key features of the approach
– Government explores and develops the resource
– Private participation is limited
Where it has been applied– Costa Rica – The Philippines– El Salvador – New Zealand– Guatemala – Iceland– Nicaragua – Turkey– Mexico – Ethiopia– Indonesia – Kenya
San Cristobal Volcano, Nicaragua
Government Acting as Developer: Pros & Cons
Pros– Mobilizes large-scale financing from public sources– Backstops resource risks through the strength of government
treasury
Cons– Some governments may not be able to afford the large scale
investment – Some countries may not have necessary in-country skills or capacity– Mobilizing financing may be cumbersome due to bureaucracy– The need to involve multiple government agencies may create
conflicts
Government Acting as Developer:MW Installed
– Costa Rica: 208 MW (3 fields) – El Salvador: 205 MW (4 fields)– Guatemala: 53 MW (2 fields)– Nicaragua: 70 MW (1 fields)– Mexico: 980 MW (4 fields)– Indonesia: 467 MW (6 fields)– Philippines: 1854 MW (7 fields)– New Zealand: 220 MW (2 fields)– Iceland: 664 MW (6 fields)– Turkey: 15 MW (1 field)– Ethiopia: 8 MW (1 field)– Kenya: 180 MW (1 field) Wairakei, New Zealand
Government Acting as Developer:Impact of Scheme Worked very well were committed and
capable to support the geothermal development (e.g., Costa Rica, New Zealand, Iceland, The Philippines)
Moderately successful with significant geothermal resources but less consistent development strategies (e.g., El Salvador, Indonesia, Kenya)
Not so successful in smaller countries that may have more pressing needs for limited government funds (e.g., Ethiopia, Djibouti, Bolivia) Krafla, Iceland
Cost-Shared Drilling:Introduction
Key features of the approach– Government shares some portion of
drilling costs and risks with a private developer; or fully undertakes exploration drilling and testing of first few wells
Where it has been applied– Japan – United States– Australia – Eastern Africa
Well test, Cove Fort, UT
Cost-Shared Drilling: Pros & Cons Pros
– Catalyzes private investment in geothermal development– Increases availability of risk capital for exploration drilling– Reduces overall exposure of financial risk to developer – Requires less public funding than full government development– Backstops some resource risks through the government
Cons– Some projects will not be viable for full scale development despite
public funding– Requires up-front public funding that may not be recoverable
Cost-Shared Drilling: MW Installed– Japan: 535 MW (15 fields) – United States: 137 MW (8 fields)– Australia 1MW (1 field, many wells drilled)– East Africa (RFP recently issued, 11 EOIs, 5
projects invited to sign grant agreement)
Impact on pace – Served as a significant catalyst for all current
geothermal power generation in Japan– Encourage drilling in United States– Catalyzed drilling but no major MW impact
due to technology choice in Australia– East Africa impact TBD
Cost-Shared Drilling: Impact of Scheme
Management of this scheme is simple It provides a significant catalyst for
private-sector geothermal development Costs to the government are significantly
less than for “Government as Developer” Government’s cost-share portion could be
recovered from the developer for successful projects, thus enabling some recovery and re-investment of funds

Resource Risk Insurance: Introduction
Key features of the approach– Insurance to hedge against the risk of
lower than expected well productivity
Where it has been applied– France – Germany – Efforts are underway to implement
this kind of insurance in Turkey, Kenya and the U.S.
Resource Risk Insurance: Pros & Cons Pros
– Risk of drilling failure for developers is reduced– Could mobilize equity capital due to reduced exposure to potential losses– Reduced burden on government; insurance is provided by specialized
entities
Cons– High insurance premiums – Increases required overall upfront investment (due to premium)– Challenging to commercially underwrite substantial uncertainty (losses) in a
relatively small global market– Complex to design, implement and monitor– Limited number of insurers offering coverage
Resource Risk Insurance: MW Installed– Germany, a few fields (for power or
combined heat and power, overall generation capacity for the German projects is <20 MW)
– France (for heat)
Impact on pace – Insurance may have helped
accelerate the pace of geothermal power development in Germany (the high feed-in tariff has played a major role in geothermal development there)
Resource Risk Insurance: Impact of Scheme
Limited availability and difficult to obtain at an acceptable price for exploration well drilling
Although the risk to developers is reduced, overall up-front funding required for exploration is increased (due to premium)
Developers who need it most may not qualify for coverage and/or their premium could be inaccessibly high
Has a high level of operational and management requirements
Well testing
Early Stage Fiscal Incentives:Introduction
Key features of the approach– Exemption from taxes and import
duties related to exploration
Where it has been applied– United States– Mexico– Turkey– The Philippines – Indonesia
Blue Mountain, US
Early Stage Fiscal Incentives: Impact of Scheme
Government reduces fiscal levies (taxed/duties) that lowers overall investment in exploration drilling
Reduces requirement for risk capital to fund early stage of a project
Simple to administer and monitor when utilizing existing fiscal architecture, but not specifically aimed at resource risk mitigation
Impact can vary depending existing taxes and levies Orita well test, US
CONCLUSIONS
Quantitative analysis indicates … From IPP Point-of View:
– early-stage fiscal support will reduce risk more compared with insurance
From Government Point-of-View:– Better leverage of government funds in cost
sharing scheme– Rapid scale-up could be from either public
developer or cost-sharing
