Introduction – Brazilian Energy Matrix 2015

Renovation of the Energy Matrix

o Uncertainties in a mainly hydropower driven system

o Need for secure energy supply and economic competitiveness

o Energy matrix based on a sustainable, diversified and competitive energy

o Increase the installed hydropower capacity (transmission lines, environmental challenges, low capacity factors…) is difficult

When plant construction was stopped in the late 1980s, approximately US$

455M in costs had already been incurred (infrastructure, basic design and

detailed engineering, import and national equipment already delivered)

Angra 3

Limitations imposed to Eletronuclear´s cashflow due to the reduction of

Angra 1 and 2 tariffs, which led to a considerable revenue loss,

prevented the company from providing the required counterpayments

to make withdrawals from the external financing

Start of the “Lava Jato” operation

Due to the above, Eletronuclear was forced to take exceptional

measures:

Payment delays

Contract suspensions / Pace reduction

General Executive Schedule revision – start of commercial

operation in December 2022

Relevant Facts 2015

ELETRONUCLEAR

Angra 3

Several actions towards creating conditions to enable the

resumption of the Project:

Reevaluation of the Project time schedule;

Feasibility studies listing the main milestones that have to be

completed, in line with the revised time schedule;

Indepentent assessment of the Project Budget;

Technical note on the price of energy and tariff;

Evaluation of the cost to cancel the Project, as well as assessment

of the costs incurred from aspects not attributable to Eletronuclear

Angra 3 New Model (still to be decided)

Definition of legal framework and business model for private partner

participation

Bidding process for private partner participation (or Inter-

Government Agreement)

New energy contractual model (tariff) to ensure private stakeholder

participation

Financial resources for Project completion (State funding or private

participation)

Angra 3 – Main Challenges

Angra 3 New Model (still to be decided)

Definition of scope for Eletronuclear (owner) and for the private

partner:

Eletronuclear to be the responsible for:

Plant commissioning and operation

Licensing activities

Design of the plant

Contracts with Areva (imported supplies and services)

Scope to be harmonized and defined, depending on the new model
