Results¹ at September 30, 2011

Revenues: EUR 65.4 billion (+8.9%) EBITDA: EUR 12.1 billion (+10.2%) Net debt: EUR 41.7 billion (+ EUR 1 billion compared to 6/30/11)

• Group's international development
• Growth in exploration-production and LNG activities
• Continuation of the investment program
• Strong financial structure and liquidity
• 2011 dividend stable or growing

Revenues at September 30, 2011 were EUR 65.4 billion with a +8.9% gross increase and +3.3% organic growth that confirm the robust performance of the first half-year, thanks to the Group's international development, good results in exploration-production and LNG activities, the contribution of assets commissioned in 2010 and 2011 despite exchange rate negative effect, mostly from the US dollar, and despite an economic environment which remains difficult.

EBITDA for the period reached EUR 12.1 billion with a +10.2% gross increase and a -0.4% organic variation compared to September 30, 2010, boosted by significant scope effects. This trend also reflects:

• strong growth in results from the Global Gas & LNG Business line thanks to exploration-production and LNG activities,
• improvement in results from the Energy Europe & International Business line, notably in North and Latin America,
• decrease in results from the Energy France and Infrastructure Business lines due to unfavorable weather conditions,
• sustained growth in results from the Energy Service business line,
• continuing good operational performance of SUEZ ENVIRONNEMENT in spite of the difficulties met in Melbourne.

At September 30, the unfavourable weather impact on our domestic markets is estimated at EUR 480 billion. In France, the gas tariff freeze decided by the government on retail regulated tariff results in a shortfall of EUR close to EUR 290 million for the fourth quarter in addition to EUR 108 million for the three first quarters 2011.

Revenues	9,127	9,752	- 6.4 %	- 6.5 %

At the end of September 2011, the Energy France revenues declined by EUR - 625 million. The decrease in volume of gas sold was partially offset by the increase in prices and volumes of electricity sales as well as by the increase in gas tariffs that do not, however, reflect the total increase in supply costs.

Natural gas sales stood at 146 TWh down -23% over 2010, due mainly to the different weather conditions between the two periods. GDF SUEZ maintains an 88% share of the residential market and 69% of the business market. Electricity sales rose +9% to 29 TWh due to increased sales to direct customers.

Electricity production (22 TWh) declined by - 7% due to poor hydroelectricty conditions in the spring of 2011, partly offset by the commissioning of two thermal power plants (Combigolfe and Montoir-de-Bretagne) in 2010 and by the development of its installed base of windfarms.

* Following the merger with International Power, EUR 1.162 in September, 30, 2010 revenues were restated from the Europe division to International Power with EUR 1.093 million euros under UK & Rest of Europe and EUR 69 million under Turkey.

BENELUX & GERMANY Division

Electricity volumes sold for the area declined 11.1% to 86.1 TWh while revenues decreased by EUR - 405 million compared to 2010 with great disparities by country: a noticeable decline in volumes sold in Belgium and Luxembourg, stable sales in the Netherlands and a slight rise in Germany.

• In Belgium and Luxembourg, the decrease in volumes, mainly to business customers was just about offset by a selling price increase as the direct result of tariff increases on transport and distribution networks.
• In the Netherlands, revenues decreased by EUR -136 million, or -12.5%, mainly due to the decrease in the average selling price across all customer segments.
• In Germany, the EUR +63 million rise in sales (+6.8%) may mostly be attributed to the proportional integration of the Gera Stadtwerke.
• Sales outside Benelux & Germany only come to EUR 392 million, a -5.3 TWh decrease.

Gas sales revenues rose +1.8% with a - 6.7% decrease in the volumes sold of 4.2 TWh. The decrease in volumes is, therefore, more than offset by the increase in selling prices that reflects market trend, in particular in Belgium. The -6.4 TWh decrease in sold volumes is attributable to the warmer temperatures in 2011.

EUROPE Division

The scope effects amounted to EUR +209 million, due essentially to the restructuring of Group business activities undertaken in partnership with ACEA in Italy.

The +2.8%, or EUR 122 million, rise in organic revenues compared to September 2010 are mainly explained by the changes below :

• Southern Europe (EUR + 134 million) had the advantage of development plans with the commissioning in August 2010 of the Heron 2 plant in Greece and the increase in the number of customers in marketing activities in Italy. In a difficult situation for the market, revenues were also boosted by the effect of a greater volume of virtual capacity purchasing contracts in Italy and the positive price effect from regulated electricity rates.
• The Iberian Peninsula (EUR 140 million) saw its electricity production fall significantly (-3 TWh), due to unfavourable market prices.
• Central and Western Europe saw revenues rise EUR +128 million due to gas rates increases, which only partially reflect costs in some countries, and due to an increase in volumes sold and distributed in Romania and Slovakia, respectively +1.3 TWh and +0.4 TWh.

INTERNATIONAL POWER

Revenues of the International Power division came in at EUR 11,768 million, up in gross terms by 44% and organic terms, 11%. Beyond the integration of the acquired IPR assets that had a scope effect of EUR 2.9 billion, sales were boosted by growth in the Latin America, Asia and Middle East regions.

The evolution of revenues at September 2011 is given in International Power's publication dated October 26, 2011.

LATIN AMERICA Region

Revenues for the region include EUR 106 million scope effects, mainly related to take-over of electrical activities in Chile in January 2010 (E.Cl). There was a negative exchange rate effect of - EUR 42 million for the region. The organic growth of the revenues is explained by the increase of the average sale price, in particular in Brazil.

Electricity sales were stable at 36.9 TWh at September 2011. Gas sales rose by 4.2 TWh to 13.8 TWh, mainly after the Mejillones LNG terminal was commissioned in the second half year of 2010.

NORTH AMERICA Region

Exchange rate effects had a negative impact on revenues (EUR -196 million) due to the depreciation of the American dollar. Scope effects accounted for EUR +682 million and represented integration of International Power's assets.

Electricity sales came to 64.1 TWh, an organic increase of +3 TWh due to good performance in the retail business line. Electricity production showed lower revenues on organic basis, following varying price effects depending on the segments and a lower volume sold that dropped - 1 TWh to 20.8 TWh.

Non-Group³ natural gas sales came to 49.2 TWh, rising +0.4 TWh in organic terms. Besides the impact of the volume, revenues benefited from a rise in average price after hedging in the LNG activity.

UNITED KINGDOM AND REST OF EUROPE Region

Exchange rate effects for the period were negative (EUR -17 million) and scope effects stood at EUR 1.191 million. These effects consisted mainly of International Power's European assets being integrated into the scope of GDF SUEZ as of February 2011.

Revenues, which rose in organic terms by +9.5% compared to 2010, were basically driven by marketing activities, notably for gas, given the volumes increase by 2.7 TWh, combined with a positive price effect.

³ It should be noted that the sales of natural gas, including intra-group sales stand at 63.5 TWh with an organic increase of 12.9 TWh.

MIDDLE EAST, TURKEY AND AFRICA Region

Middle East, Turkey and Africa revenues rose +75% in gross terms, reaching EUR 871 million at September 30, 2011, including the integration of International Power's assets and full consolidation of the Al Hidd plant in Bahrain. After the negative exchange rate effects (EUR -36 million due mostly to the US dollar's depreciation), revenues in organic term rose to EUR 130 million, or +28.2%.

This growth was mainly driven by electricity sales in Turkey and by operating/maintenance activities in Oman.

Electricity sales for the region stood at 16.6 TWh, up by +4 TWh, mostly due to scope effects related to International Power's assets, including full consolidation of Al Hidd. Natural gas sales came to 2.6 TWh, up +0.6 TWh.

ASIA Region

Given the appreciation of the Singapore dollar and the depreciation of the Thai Baht (EUR +1 million), scope effects following integration of International Power's assets and the proportional consolidation of natural gas distribution assets in Thailand, the organic growth stood at EUR +108 million, or +10.6%.

This growth was mainly driven by Thailand after the commissioning of the CFB 3 coal plant and by a better performance of the activities in Singapore.

AUSTRALIA Region

Revenues stood at EUR 624 million representing the contribution of assets by International Power. Electricity sales stood at 16 TWh, a decrease compared to 2010, mainly due to unfavorable climate conditions.

GLOBAL GAS & LNG BUSINESS LINE

in millions of Euros	Sept 30, 2011	Sept 30, 2010	Total Change	Organic Change
Revenues	7,322	6,557	+11.7%	+13.4%
Revenues including intra-Group	15,120	14,043	+7.7%	n.a.

The revenues contributed by this business line at September 30, 2011 were boosted overall by the increase of Exploration/Production sales, the LNG activity and sales from the Supplies department offsetting the lower sales to European Key Account customers.

The evolution of revenues is explained by the following effects:

• an increase in short term sales in a situation of fast-rising prices on the market with volumes at 82.8 TWh⁴ , at the end of September 2011 versus 67.2 TWh at the end of September 2010.
• a 7.8 TWh rise in external LNG sales with 31 TWh (34 cargoes, 16 of which went to Asia) in September 2011 versus 23.2 TWh (25.5 cargoes, 9 of which went to Asia) at the end of September 2010 and the impact of higher prices for commodities.
• a 15.7 TWh decline in natural gas sales to European Key Accounts (with sales going from 119.1 TWh at the end of September 2010 to 103.4 TWh at the end of September 2011) in very competitive conditions.
• a growth of revenues from Exploration/Production mainly related to the combined increase in the Brent average price, the NPB average price and the rise in the level of hydrocarbon production mainly due to the commissioning of the Gjoa and Vega fields in Norway. Total hydrocarbon production at the end of September stood at 44.8 millions of barrels of oil equivalent (Mboe) (29.4 Mboe for the Group share).

Revenues including intra-Group	4,054	4,192	- 3.3%	n.a.

INFRASTRUCTURE BUSINESS LINE

The decrease in revenues including intra-group, came from a -38 TWh decrease in quantities dispatched by GrDF due to milder temperatures than in 2010 and less commercialization of storage capacity in France, partially offset by:

• the start of commercial operations at Fos Cavaou at 20% capacity on April 1, 2010, and at full capacity since November 1, 2010;
• for transport activities, the adjustment of tariff in France on April 1, 2010 (a +3.9% increase) and on April 1, 2011 (a +2.9% increase);
• adjustments in the distribution infrastructures access tariff (+0.8% increase on July 1, 2010 then a 1.85% decrease on July 1, 2011).

In the same climate and regulatory conditions, revenues stood at EUR 984 million, a rise of +16.6% compared to September 2010. This growth is explained by :

• the development of transport, storage and terminaling activities on behalf of third parties due to the opening of markets;
• the start of commercial operations of Fos Cavaou commercial activities.

⁴ Including sales to other operators.

in millions of Euros	Sept 30, 2011	Sept 30, 2010	Gross Change	Organic Change
Revenues	10,197	9,640	+5.8%	+3.0%

In France, the level of activity in services (COFELY France) saw a -1% decrease in organic terms with the effects of past commercial development and improving energy prices partly offsetting unfavorable climate conditions. Installation and maintenance activities grew organically by +8.7%.

In Belgium and the Netherlands, activity is growing organically, +5.4% and +14%, respectively. In Belgium, the effects of good order taking in installation activities along with the sustained commercial development of services explain this trend. In the Netherlands, sales are moving dynamically with the signing of large-scale orders that have gone into production quickly and that are sustaining activity.

Tractebel Engineering's activity remained stable in terms of organic change.

Outside France and Benelux, the business line's activity fell by -3.6% in Northern Europe. In Southern European countries, activity is down by - 7.3%. This decrease came mainly from Italy and Spain. Lastly, the revenues from the International Overseas region has grown organically by +4.1%.
