Geothermal energy technologies and cost drivers

Cost Drivers

• › Temperature
• › Drilling Depth
• › Flow Rate
• › Network Connection
• › Generation Plant
• › High upfront costs – drilling, fracture stimulation, connection, plant
• › Project economics are geology and location specific

Our Australian projects

• › Our flagship Paralana project
  • › Drilling campaign at our site 600km north of Adelaide is nearing completion

(refer presentation by Peter Reid, PTR Exploration Manager on 12 November at 1:15 pm Stream 1 - Exploration)

• › East Gippsland in Victoria
  • › Awarded a 9,000km2 geothermal exploration permit to develop a Hot Sedimentary Aquifer
• › Renmark in South Australia
  • › Two geothermal exploration licenses (GELs), located 26 km northwest of Renmark in the Riverland region
  • › Close to two major transmission lines capable of carrying in excess of 220 MW of power

Paralana geothermal energy JV project - snapshot

Our Paralana project 600km north of Adelaide in South Australia

• › Anecdotal evidence from the Paralana hot springs in the nearby Flinders ranges
• › High heat flow 128 mW/m²
• › Measured temperature of 109˚C at 1807m
• › Mature basin, stable formations, no hydrocarbons
• › Inferred geothermal resource of 230,000 PJ – independent assessment by competent person - HDRPL
• › Customer for initial 3.75MW plant at nearby Beverley Mine
• › Potential commercial viability at all stages - scale up plan to 30MW and beyond

Paralana 2 well drilling – key success factors

• › The well is stable with no technical challenges experienced and was terminated at a depth of 4,012m
• › Key success factors developed to guide Paralana project and incorporated in JV decision-making, GDP grant contract and REDP grant application
• › Success factors exclude consideration of grant monies
• › Key success factors for the Paralana 2 well are:
  • › Equal/better industry safety & environment benchmarks
  • › Target a minimum drill depth of 3600m and maximum drill depth of 4000m
  • › Achieve a minimum temperature of 170˚C at 4000m expect to meet or exceed (to be measured)
  • › Formation evaluation and selection of zones for stimulation – permeability/in situ stress field - observed inflows to well commencing at 3690m (to be assessed)

Paralana project – HEWI model and economic assumptions

HEWI Model at Paralana

The required heat exchanger is created in the porous insulating layer above the granite heat source. This is expected to reduce risk, cost and time

(*Long Run Marginal Cost calculation over 20 years, includes all costs, consistent with energy industry comparisons made by the Electricity Supply Association of Australia, McLennan, Magasanik and Associates and the AGEA Economics Committee)

Key Economic Assumptions:

• › Temp. of 170˚C to 200˚C at 3,600m to 4,000m
• › Flow rate of 75 litres per sec conservative compared with other public announcements
• › Net output per production well of 3.75 MW based on flow and inclusive of parasitic loads
• › 20 year project life, includes all costs with 12 wells for a 30 MW development and connection to customer and results in a LRMC* of $107/MWh (delivered), comparable with independently assessed industry LRMC ranges
• › Bundled price for sale of output black and RECs expected to be > $140/MWh due to current high off grid price at Beverley mine
• › JV retains the full value of black and RECs no predetermined price – retain full upside
• › Potential for commercial viability at small scale 3.75 MW, 7.5 MW and 30 MW

Paralana joint venture arrangements

• › Beach Petroleum Farm-in (Jan 2007) for up to $30M for 36%
  • › $5M first well and stimulation
  • › $5M second well and stimulation earns 21 %
  • › After HEWI Option to earn a further 15% for $20M
  • › Plus equity share of project costs at every stage
• › TRUenergy Farm-in (Aug 2008) for up to $57M for 30%
  • › $3M first well and stimulation
  • › $3M second well and stimulation earns 10%
  • › After HEWI Option to earn a further 5% for $7M
  • › After 7.5 MW pilot plant Option to earn a further 15% for $44M
  • › Plus equity share of project costs at every stage

Under the Paralana Joint Venture post HEWI

For a $200m , 30 MW demonstration project with JV options taken up – Petratherm would require minimal investment - retains 34% of project and resource
