Letter from the PresidentIts with great pleasure that we present ou the 2012 AES Dominicana StatisticalReport, highlighting its main assets, operational performance, other lines of businessand the electricit market overall. At the end of 2012, AES Dominicana contributedan average of 37.8% of all the energ that was demanded b the National ElectricInterconnected Sstem (SENI) with a total of 5,045 GWh injected, surpassing 2011senerg generation and demonstrating to be the leader in the national electricitmarket.

78% of this energ was traded in the Contract Market to Distribution Companies,creating signicant savings for the Dominican government by providing the cheapest

energ in the National Sstem. Our units reached operational milestones, amongthose were AES Andres and ITABO S.A.s units, which generated 2,089 GWh and1,613.6 GWh with natural gas and coal respectivel, eceeding both their annualrecord highs. AES Andres and DPPs units achieved a high rate equivalent availabilitfactor.

During 2012, the natural gas market achieved sales records, showing growthof 149.55% over the previous ear, increasing the sales directed to the electricitsector, which caused AES Dominicana to conduct spot purchases of LNG in theinternational market to meet rising demand.

AES Dominicana shows its commitment to the countr b strengthening its positionusing natural gas and efciently restoring the use of coal. Proof of this is the Mximo

Galardn Silver Medal award we received, in the Major Industr categor of theNational Qualit Awards. Our culture of operational ecellence a nd asset managementallows us to contribute to the countrs sustainable development, the environmentand the communities we serve.

At th e end o f thi s year 2012,

AES DOMINICANA BACKGROUNDThe rst investment of AES in the Dominican Republic was the purchase of DPP in 1997 from NGC, an asset that

was in their power as a result of their merger with Destec companies. DPP is the owner of Los Mina V and Los MinaVI, two 118 MW open ccle gas turbines.

From Ma of 1996 until August of 2001, DPP operated under the Independent Private Producer scheme, sellingall of its production to La Corporacin Dominicana de Electricidad (CDE). Then, after an agreement between DPPand CDE, the contract between both parties was cancelled and a new electricit sale arrangement was establishedbetween DPP and EDEESTE, which included a backup contract with the CDE.

In 2000, AES conrmed its commitment to the long-term development of the Dominican Republic by constructingAES ANDRES. The project included a combined cycle of 319 MW, a liqueed natural gas terminal and a gas pipeline

connecting to the DPP power st ation.

In December of 2000, AES took another important step when it acquired the assets of GENER, obtaining a partici-pation of 25% in the ITABO S.A. power plant.

Since Ma 1st, 2003, Dominican Power Partners operates to suppl its electricit sales contract with EDEESTE,selling its ecess generation and buing what it needs in the spot market.

Also in 2003, AES ANDRES began its operations and became the most efcient power station of Latin America,

representing a jump towards sustainable development for the countr using clean energ. This new investmentimproved the strategic position of the countr that formerl depended 90% on petroleum derivatives to suppl itselectricit needs.

In 2006, AES Dominicana acquired another 25% of the ITABO S.A. equit, formerl owned b El Paso. AES, nowwith 50% of ITABOs equit, took control of the operative and administrative areas.

ITABO S.A. INTERNATIONALPIER

The International Pier of ITABO is located in thecoastal area of the ITABO power plant in themunicipalit of Bajos de Haina in the provinceof San Cristobal. The pier is located net to thewestern port of Haina, approimatel 8 kilom-eters southwest of Santo Domingos westernquadrant.

Since 2006, ITABO International Pier has beenoperating as a reception point for mineral coal,which is utilized in its vapor units, adding agreater degree of autonom to the process andreducing the overall cost of coal.

The pier etends 535 meters into the sea. It hasa sstem to transport solids with the capacitto load and unload bulk products. In addition, ithas a mooring sstem with si (6) tugboats, fourof which serve for the ships arrival and two forthe ships engagement to the pier. It also has asignal sstem for approaching vessels, locatedin two towers with adjacent lamps, as well aswater lighting tracks and a lighting sstem in oneof the tugboats.

CRyOGENIC DISTRIBUTION TERMINAL

In 2009, AES Dominicana decided to invest in the rst LNG tank loading terminal in Latin America, for the distribution of liqueed natural gas

directly to other customers besides AES. The advantage of using liqueed natural gas is the ability to carry higher energy content to distant

locations without incurring losses during transportation.

The LNG tank loading terminal has two loading bas (with the possibilit of doubling the capacit) and a loading rate of 68 m3 / h, which means

that the average customer service time (from admission to the comple to the departure) is approimatel one hour.

Main Characteristics:

Fourteen (14) meters deep: Enables the docking of vessels like

Handymax (45,000 mt) and Panamax (65,000 mt).

Auto-discharging vessels required.

Discharge Capacity of 1,200 metric tons per hour.

In 2011, Estrella del Mar II , a Bi-Fuel power plant that runs with natural gas and Fuel Oil #2 that belongs to the Transcontinental Capital Corpo-

ration group, began its operations. This generation plant gets natural gas through a pipeline connected to gas station # 4 of DPP in Los Mina.

Since 2007, two ears after AES Andres signedits rst natural gas supply agreement with a local

distribution compan, AES Dominicana has beenat the forefront of the business in selling natural

gas, opening the door to nationwide distributioninto new markets that previousl could not enjo

the advantages of this fuel.

Toda, AES Andres is the onl distribution ter-minal of liqueed natural gas in the Dominican

Republic, as well as the rst to be installed in

Latin America. This adds value b contributingto the evolution and diversication of the national

energ matri.

WHOLESALE ELECTRICITy MARKET

BRIEF HISTORy OF THE DOMINICAN ELECTRICITy SECTORIn 1997 the capitalization process began. It was instituted due to seriousproblems in the electricity market caused by a decit in energy generation,

poor qualit service and a lack of capital investment for the development ofthe electricit sector.

The capitalization process was formalized in June 24, 1997, with the pub-lication of the State Companies Reform Law. Before this process, genera-tion, transmission and distribution assets in the Dominican Republic wereowned b CDE, who b law, was the onl entit authorized to operate inthe electricit sector.

In the mid 90s, CDE signed several power purchase agreements with inde-pendent power producers; increasing the sstems installed capacit withprivate capital. During this period, the sector was regulated b a series ofadministrative resolutions issued b the Industr and Commerce Ministr.

Through the different stages of the capitalization process, the assets heldb CDE were divided into eight state-owned companies: CDEEE, a parentholding compan; three distribution companies: EDENORTE, EDESUR andEDEESTE; three generation companies: HAINA, ITABO, HIDRO; and t hepower transmission compan ETED.

In 1999, the three distribution companies and the two thermal genera-tion companies were capitalized through the sale of 50% of the stocks toprivate investors. The Dominican Government remained with 49% of thestocks and the last 1% was sold to the emploees of these companies.

In Jul 2001, the Electricit General Law was issued, establishing the institutions ofthe sector and the rules under which it will operate. In Jul 2002, the Electricit Gen-eral Law Rulebook was issued, completing the electrical sectors new legislation.

In 2007, law number 186-07 modied the Electricity General Law and its Rulebook.

The new laws goal was to penalize electrical fraud and establish other measures toobtain the electrical sectors nancial viability.

TRANSMISSION

The Electrical Transmission Compan of the Dominican Republic (ETED) is a state-owned compan with the primar objective of building, oper-ating and sustainabl managing the grids and substations of the electric interconnected sstem of the Dominican Republic, in order to providequalit service at reasonable prices.

The electrical infrastructure consists of a total length of 4723.95 km of lines at 345, 138 and 69 KV, where the 345 KV network, which links theNorth Zone with the area of Santo Domingo, is the most economicall important and functional one. It has a length of 129.9 km at a maimumtransmission power of 1200 MVA per circuit.

In addition, the National Transmission Sstem consists of approimatel 2660.93 km of transmission lines at 138 kV and can be referred to asthe Sub-backbone network; also 1933.13 km of 69 kV lines. It operates and maintains approimatel 85 substations, owned and shared.

Because of its radial conguration, the National Electric Interconnected System is divided into four zones: Santo Domingo Zone, South Zone,

North Zone and East Zone. The most important substations of these zones are: Palamara and Hainamosa in the Santo Domingo Zone, Pizarretein the Southern Zone, Bonao II and Canabacoa in the Northern Zone and San Pedro II in the Eastern Zone.

ELECTRICITy DISTRIBUTIONThree distribution companies manage the electricit distribution of the national interconnected grid:

EDESUR Dominicana, S. A.EDENORTE Dominicana, S. A.Empresa Distribuidora de Electricidad del Este, S. A.

These companies obtain their energ from the electric sstem through high voltage bus bars, which are later transformed to minor tensions andthen conducted through each companys grids within their zones of concession until these reach their nal users.

The distribution compan lines within the national grid contain a mechanism of automatic load shedding, implemented in various distributioncompan substations through low frequenc and low voltage relas, which serve to disconnect the electrical load automaticall through differentphases. This mechanism is reviewed and updated periodicall b the Organismo Coordinador, the independent market operator.

ENERGy BALANCE

In the following table we can observe the monthl energ balance during 2012. This includes the net injections of thegeneration companies as well as the distribution companies and non-regulated users withdrawals; the last two have beengrouped independentl from the generation companies with which the have a power suppl contractual arrangement.

AES Dominicana contributed 37.8% of theenerg in the Electricit Wholesale Market, reaching the highest market share in the generation sector.

MAxIMUM DEMAND

The sstems maimum demand is the highest power consumed b distribution companies. Generall, this happens during sstem peak hours. Maimumdemand is data used in capacity recalculation since a preliminary estimated maximum demand is used prior to computing these gures. The system re-munerates onl the maimum capacit effectivel recorded as demanded during the ear. The following table shows 2012s monthl power production andpower consumptions during sstem peak hours.

GLOSSARy

BAR: The point of the electrical sstem prepared to deliver and withdraw electricit.

BTU: British Thermal Unit of measurement. It is a unit of heat in the English European Sstem. Its equivalent in the International Sstem (IS) is theCalorie. The prices of Natural Gas are usuall epressed in US$/MMBtu. 1 BTU is equivalent to 252 Calories (Cal).

CONTRACTS MARKET: The market for t ransactions of sale and purchase of electricit based on freel negotiated contracts for suppl.

COMBINED CyCLE: a machine composed of t wo phases: one phase of gas and the other phase of steam. Tpicall the whole entit consists of agas turbine, a heat recuperation boiler, a steam turbine, and one or several electrical generators.

FIRM POWER: The power that can be supplied b each generating unit during peak hours, with a high level of securit/safet.

FREQUENCY REGULATION: Actions necessary to maintain frequency within the permissible tolerances dened for the system. The OC establishesthe regulation parameters, and the generator companies are responsible for providing service through their control centers.

FUEL OIL: A petroleum derivative obtained as a residue after the distilling process. Being a fuel, which is heavier than those that can be distilled atatmospheric pressure, Fuel Oil is used as a fuel for electrical energ plants, boilers, and ovens.

GAS TURBINE: A machine composed of an air compressor, a turbine especiall designed for this purpose, and an electrical generator. The turbineconverts thermal energ from fuel, which is produced as a result of the epansion of hot gases from the eplosion of the miture of compressed air,fuel, and ame, into mechanical energy that is used by the electrical generator to produce electricity.

HyDRAULIC TURBINE: A machine that uses kinetic energ and power from water to produce a rotation movement which, transferred through anais, directl moves a machine or generator that transforms mechanical energ into electrical energ.

LIQUID NATURAL GAS (LNG): Natural Gas processed to be transported in liquid form. It is the best alternative for transporting and storage becausewhen transformed into liquid as atmospheric pressure and 163 C , the liquefaction process reduces the volume of gas b 600 times.

MARGINAL CENTRAL UNIT: This refers to the generating unit or units, which at optimum load dispatch increase their generation when the demandis marginall increased.

MARGINAL SHORT-TERM COST: The variable costs necessar to produce one additional unit of energ, considering the demand and the genera-tion infrastructure available.

MAxIMUM ANNUAL DEMAND: The maimum gross half our demand, during a calendar ear, of the total of the generator units of the sstem, oc-curring within the sstems peak hours.
