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)
Effective preservation (proven techniques from Angra 2)
Around 13,500 tons of already
delivered components

Heavy components for the primary
circuit (RPV, SGs, RCPs, PRZ)

Note: The baseline for this Project Progress is of 30,34% in 2009 (Project Resumption – civil
works). The progress above reflects the General Executive Schedule (Rev 4), with the start of
commercial operation in December, 2022

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 – Main Challenges
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)
Engineering Works
Civil Construction, Eletromechanical Erection and Commissioning
Licensing and Enviromental commitments
Applicability of the new model to new NPPs
ELETRONUCLEAR
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
Engineering support during construction and erection
Digital I&C (hardware)
