Presentation outline

1. Geothermal sector in Australia and SA

2. Petratherm Limited update

3. South Australian - wind and solar sectors

4. Current issues

5. The facts about Renewables and the RET scheme


Geothermal Sector in Australia and SA - Seen major changes

• Initially growing from one pioneering ASX listed company

(GDY) to include more than ten

• At it's peak the sector had more than 35 companies

(private and public)

• Seven deep geothermal wells by three companies - with

only a few wells successful

• Last two years has witnessed a major reduction in companies active in the sector

• Challenges are both technical and commercial but the potential remains enormous

• Market sentiment has been negative for some time -

making funding difficult

Petratherm Update - Changing to address new circumstances


• PTR successfully drilled one 4 km deep well and is the only ASX listed company with an active JV partner - BPT

• 85 % of the spend on Paralana to date from PTR and its

JV partners - private sector has done the "heavy lifting"

• Paralana project seeking additional partner to meet $13m federal government grant conditions of $5m in equity by

19 July 2014.

• Board restructure from six to three directors, prudently preserving cash and assessing new investment opportunities to create shareholder value

• Tenerife, conventional geothermal project - actively

seeking parties to acquire the project

• PetraGas, unconventional oil and gas - in discussions with a large Australian energy company to JV the project

SA Wind and Solar - Change in fuel source for electricity over 9 years

Historical Market Information

SA Wind and Solar - National leader in wind and solar PV

Wind

• 38% of nation's installed capacity

• In 2012/13 delivered 28% of State's electricity

requirements

• 2011/12 was first year that wind generation

overtook coal


Source : Renewables SA

Solar Photovoltaic

• 400 MW individual installations - similar size

Pelican Pt power station

• 1 in 5 households have solar PV

• Delivers 3.8% of annual energy demand

Current Issues - Many, varied and confused


• Recent reduction in grid sourced electricity from the impact of solar PV - pronounced in SA

• Recent increases in cost of electricity across

Australia - causes and remedies?

• Carbon tax policy and its flow through impact into

electricity prices

• Federal Government budget and review of Climate

Change related policies and bodies

• Direct Action Policy - Emissions Reductions

Scheme white paper released on 24 April 2014

• Current review of the Renewable Energy Target (RET) Scheme that was originally established by the Howard Government

The facts - Confirm that the RET scheme works and should continue


• Wholesale price increases are reduced by the

RET

• Cost of RET is largely offset by reductions in wholesale prices in the near term

• Repealing the RET would increase retail electricity prices and increase greenhouse gases

• Increasing and extending the RET will further

benefit customers

• The RET will drive new investment and

significant job creation
