AREVA Solar in Southern Africa An Introduction

May 2010

World leader in the energy business

N°1 in the entire nuclear cycle

N°3 in electricity transmission and distribution

A technology leader in renewable energies

Our mission

Enabling everyone to have access to ever cleaner,

safer and more economical energy

Our strategy

To set the standard in CO2-free power generation

AREVAEnergy is our core business

AREVA’s Renewable Energy Portfolio

BIOENERGIES

EPC for turnkey delivery of biomass fired power plants

Ownership of range of critical technologies- combustion, gasification, etc.

5MW Off-shore wind turbine design, manufacturing and commissioning

Vertically integrated in blades

WIND POWER

SOLAR AREVA is leveraging its EPC know-how

into solar thermal projects

AREVA Solar’s CLFR technology

Simple. Scalable. Reliable.

Reflectors focus sun’s

heat onto elevated

receivers

Water flows through

tubes in the receivers

Concentrated sunlight

boils the water,

generating high-

pressure, super-heat for

power generation and

industrial steam uses

Vessel Code is internationally

renowned for setting standards of

excellence in safety and reliability

AREVA Solar is the first and only

ASME-certified solar boiler

manufacturer

An ASME “S” Stamp is

considered the industry hallmark

of acceptance and certification

Recognized in more than 100

countries

Comprehensive, cost-effectiveCSP energy solutions

Standard commodity materials and construction

High degree of localization (50%+) and local manufacturing (jobs)

Land efficiency

Compact footprint for highest land efficiency

Up to 50% more energy production per hectare than competing technologies

Design simplicity

Direct steam generation; Water as the working fluid = simple cycle integration

No costly heat exchangers; Fixed receiver design; no moving joints

Environmental benefits

No synthetic working fluids or toxic materials; No solar field VOC emissions

Low wind profile

Low elevation of mirrors reduces wind loads

CSP Reference Plant

200 MW = 1 Square Mile = 259 Hectares Lower natural habitat mitigation

costs

Less time-intensive permitting

process as a result of smaller site

footprint

Easier access to contiguous, flat

land (<3% grade) and

transmission

Lower land and grading costs,

and ongoing O&M costs

Greater ability to site at existing

power plant and industrial sites

The competitive advantageof land efficiency

• Boiler units composed of

multiple SSGs

• Each SSG contains one receiver

with boiler tubes

• Receiver heated by reflector

rows in segments

• Segments comprised of factory

assembled reflectors and drives

Modular, Scalable Deployment

ASME “S” Stamp

• American Society of Mechanical Engineers (ASME) Boiler & Pressure

Vessel Code is internationally renowned for setting standards of

excellence in safety and reliability

• Ausra is the first and only ASME-certified solar boiler manufacturer

• An ASME “S” Stamp is considered the industry hallmark of

acceptance and certification

• Recognized in more than 100 countries, including U.S. and Canada,

as a means of meeting government safety regulations

• Ausra also received the National Board Certificate of Authorization

"NB" to register its solar boilers.

Rapid Field Erection

• Minimal grading required (3%

grade acceptable)

• Simple pier foundations (100

per SSG)

• Structural Steel placement and

tower lift

• Receiver (boiler tube and

housing) assembled at grade,

hoisted, hydrostatically tested

and stamped

• Assemble reflectors on beams

and connect drive

Business model: onsite manufacturing and local partnerships

Onsite manufacturing with high degree of

local sourcing

Technology designed to use off the shelf

components (mirrors, steel structure)

Assembly plant next to the power plant

Mix of AREVA and local engineering

services

Civil engineering, detailed engineering

outsourced to local partner

O&M provided by local partners under

supervision of AREVA

AREVA retains operational role in return for

offering performance guarantees

Day to day O&M performed by trained local

operators

Significant local job

creation potential

Construction: 200 FTE for 2

years for 2 years for 50 MWe

(Spanish benchmark)

Manufacturing: 30-50 FTE for

50 MWe (US benchmark)

O&M: + 2 FTE/25 MWe (US
