Why Brazil needs
Flexibility and Security of
Gas supply?
Flexibility is the ability of supply to follow continuously the evolution of the demand...
9
Demand-Supply balances: seasonal, monthly, weekly, daily and intra-daily
... Brazil has a very high need of flexibility
during the dry seasons
during the dry years

4 historical generation peak
Thermal dispatch:
Extreme variability of the gas
to power demand:

from 8 to 50 MMm3/d
i.e. +70% of the gas demand
The sources of flexibility....

How is Brazil doing and is it sustainable?
Portfolio optimization of the fully integrated national monopoly
Construction of 3 LNG regasification terminals in 5 years to
import LNG when needed
Gas-fired power plants are dispatched with 60 days of
anticipation to organize LNG imports
Future role of PETROBRAS?
Creation of a Gas Market open to third parties?
In average low load factor of the terminals
LNG supply - constraints and risks (sea conditions, geopolitics…)
Mid-terms needs exposed to spot LNG market
Is it responding well to the power sector needs?
Will it support gas to be the preferred fuel for thermal units?
New challenges
15
Furthermore, there is significant uncertainty for the near future:
• Bolivian gas production
• Pre Salt gas production
• Balance of the power intermittent sources (wind, solar...)?
• Opening of the gas market?
• Gas pricing?
The need for gas flexibility is structural in Brazil
The answer should be structural too
volume and flexibility available?
Underground Gas Storage:
a solution for Brazil?
17
Underground Gas Storage offers unique services without equivalent
High volumes of energy stored in the country of delivery (not abroad)
High withdrawal rates: volume rapidly available to the consumers
High reliability: a proven technology; gas immediately available
High operational safety: between 600 and 2,000 meters of depth
18
The understanding of Brazilian Stakeholders is growing
Gas para Crescer reveals a great interest from the participants
CNPE directives: -> review the authorization process
-> stimulate the activity
Initiatives of the ANP: UGS seminary in 2015 and Consultation of
Interest in 2016
The stakeholders needs to better understand the
services of a UGS
ENGIE is willing to accompany the value
discovery process for Brazilian partners
19
To sum up: Underground Gas Storage in Brazil
Creating UGS in Brazil is likely possible
— Onshore depleted field exists
— Positive outlook for gas
Creating UGS in Brazil is relevant:
— to improve the reliability of the gas supply chain
— to optimize the costs and gas competitiveness
UGS and
Brazil
Favorable
preconditions
Creating UGS in Brazil needs to be supported:
— Development is not fast and easy
— Market visibility to be ensured in the long run
— Investments to be secured to allow private investment
