STATISTICAL REPORT 2013AES DOMINICANA 10 11
Letter from the president
Edwin De los SantosPresident
As AES Dominicana new president, I dedicate this document proof of the
Company’s achievements to whom was the impulsor of a lot of initiatives that today we celebrate and who carried the
wheels of the company all the way until his unexpected
passing, our friend Marco De la Rosa.
“
“
It is a great pleasure to present the 2013 AES Dominicana Statistical Report, which highlights our
principal assets, operational performance, as well as important business lines information and a
variety of electricity market data as a whole.
This year, our generation units achieved new operational milestones among which stand out that
AES Andres and ITABO, S. A. exceeded their energy generation historic annual maximum with
2,099 GWh and 1,701 GWh based on Natural Gas and Coal respectively. By the end of 2103, AES
Dominicana supplied an average of 36.6% of the total energy demand of the Dominican Republic’s
Electrical System, Sistema Eléctrico Nacional Interconectado (SENI) by the Spanish name. This
means that AES Dominicana injected 5,075 GWh, overcoming the 2012 annual energy maximum
and reaffirming with this the fact that AES is the leading company of the national electrical market.
The 84% of AES Dominicana’s produced energy was acquired by the Distribution Company’s
(DISCOS), which meant significant savings for the Dominican Government, by offering them the
most economical energy of the National Electrical System. Throughout this year, the Natural Gas
Market recorded new sales records, achieving an increment of 2.4% from the past year sales,
increasing the sales made to the Generation Industry and as a consequence an increase of the
LNG purchases in the international market in order to supply the uprising demand of the fuel.
On the corporate environment, AES Dominicana shows its commitment with this county by
strengthening its position regarding the environmental protection. As a proof of this we were
awarded with the recertification of ISO 14001, receiving outstanding feedbacks from the ISO
auditors regarding the excellent performance and robust management of the environmental
management of our generation units and corporative headquarters. On the industrial safety area,
this year’s DuPont survey showed a 97% score for AES Dominicana, which was the highest score
of all AES Corporation businesses, consolidating us as a company with a world class safety. The
AES group was also awarded by the American Chamber of Commerce of the Dominican Republic
(AMCHAMDR) with the first place on Corporative Government best practices.

STATISTICAL REPORT 201315AES DOMINICANA 14
The first 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 Mina VI, two
118 MW open cycle gas turbines.
From May of 1996 until August of 2001, DPP operated under the Independent Private Producer (IPP) scheme, selling
all of its production to La Corporación Dominicana de Electricidad (CDE). Then, after an agreement between DPP
and CDE, the contract between both parties was modified and a new electricity sale arrangement was established
between DPP and EDEESTE, which included a backup contract with the CDE.
Background In 2000, AES confirms its commitment to the long-term evolution of the Dominican Republic
by building AES ANDRES generation facility. The project included a combined cycle generation
system of 319 MW, a Liquefied Natural Gas (LNG) station and a gas pipeline linking up the DPP
power station to AES Andres.
In December of 2000, AES took another important step when it took over the assets of GENER,
acquiring a of 25% in the ITABO S.A. power generation facility’s.
Since May 1st, 2003, Dominican Power Partners operates to supply its electricity sales contract
with EDEESTE, selling its excess generation and buying what it needs in the spot market.
Also in 2003, AES ANDRES began its operations and became the most efficient power station
of Latin America, representing a jump towards sustainable development for the country using
clean energy. This new investment improved the strategic position of the country that formerly
depended 90% on petroleum derivatives to supply its electricity needs.
In 2006, AES Dominicana acquired another 25% of the ITABO S.A. equity, formerly owned by El
Paso. AES, now with 50% of ITABO’s equity, took control of the operative and administrative areas.

STATISTICAL REPORT 201329AES DOMINICANA 28
AES Andres’s International Pier
AES Andres Power Station is located at Boca Chica, just fifteen (15) minutes from Santo Domingo. The power station
has a pier and a LNG terminal that also has the capacity to tranfer Fuel Oil #2.
Liquefied Natural Gas (LNG) Terminal
Inside the LNG facility, the unloading system consists of three (3) unloading arms designed to handle a transfer rate of
10,000 m3 per hour of LNG. It also has a double wall cryogenic tank with a capacity to store 160,000 m3 of LNG. In
addition, the terminal has a re-gasification system with the capacity to convert 370 million cubic feet from liquid to gas
daily . Finally, it has a boil-off security system to handle the boil of gas generated as a consequence of the storage and
conversion process that takes place in the system, in order to keep the inner pressure of the tank at an atmospheric
pressure.
AES Andres – DPP Natural Gas Pipeline
In addition to the LNG Terminal, a natural gas pipeline was built in order to supply natural gas to the DPP power
units, improving its efficiency and competitiveness. Technical Details: Length: 34 km / Pipe Diameter: 12 inches / Max
Pressure: 100 bar / Average Pressure: 50 bar / Control Valve Station: Five (5)
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 Corporation group, began its operations. This generation plant fuel is supplied through a
pipeline connected to DPP # 4 gas station, located at Los Mina’s facility.
Cryogenic Distribution Terminal
In 2009, AES Dominicana decided to invest in the first LNG truck loading terminal in Latin America, for the distribution of
liquefied natural gas directly to other customers besides AES. The advantage of using liquefied natural gas is the ability
to transport higher energy content to distant locations without incurring losses during the transportation process.
The LNG truck loading terminal has two loading bays (with the possibility to duplicate the capacity) and a truck loading
rate of 35 m3/h each bay, which means that the average customer service time (from admission to the complex to the
departure) is approximately one hour.
Fuel Reception Facilities
ITABO S.A. International Pier
The International Pier of ITABO is located in the coastal area of the ITABO power plant in the municipality of Bajos de Haina in the
province of San Cristobal. The pier is located next to the western port of Haina, approximately 8 kilometers southwest of Santo
Domingo’s western quadrant.
Since 2006, ITABO International Pier has been operating as a reception point for mineral coal, which is the main fuel of the this
steam process that power the units, adding a greater degree of autonomy to the process and reducing the overall cost of coal.
The pier extends 535 meters into the sea. It has a system to transport solids with the capacity to load and unload bulk products.
In addition, it has a mooring system with six (6) dolphins, four berthing dolphin providing a point to moor and two mooring dolphin
for the ship’s engagement to the pier. It also has a signaling system guiding the approaching vessels, located in two towers with
adjacent lamps, as well as water lighting tracks and a lighting system in one of the tugboats.
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.

Since 2007, two years after AES Andres signed its first natural gas supply agreement with a local distribution company; AES
Dominicana has been at the forefront of the business in selling natural gas, opening the door to nationwide distribution into new
markets that previously could not enjoy the advantages of this fuel.
Today, AES Andres is the only distribution terminal of liquefied natural gas in the Dominican Republic, as well as the first to be installed
in Latin America. This adds value by contributing to the evolution and diversification of the national energy matrix of the region.
The following chart shows the percentage of natural gas that AES Andres sold in the Dominican market in 2013 separated into three
economic sectors: Industrial, Electricity Generation and Transportation (Natural Gas Vehicles).

STATISTICAL REPORT 2013AES DOMINICANA 36 37
Operational KPI’sThe following table shows the most common indicators and operational rates applied to the power generation units of AES
Dominicana. As we can evaluate from the following chart the 2013 Equivalent Availability Factor (EAF) was a very particular indicator
for each one of AES Dominicana generation units. 2013 was a great year for AES Andres and DPP considering that the EAF levels
go through 85.6% for Los Mina V to a great 94.3% for AES Andres. This represents the result of all the effort and investment
dedicated to the Operational Excellence.
Other important fact is that through all 2013 the EAF percentage for ITABO’s generation Unit #1 (ITABO 1) increased on a 11%
versus the 2012 EAF. Also AES Dominicana counted with the support of the Fondo Patrimonial de las Empresas Reformadas
(FOMPER), on the hard work to position ITABO, S. A. at the vanguard of operational excellence and administrative gestion of the
AES Group.

STATISTICAL REPORT 2013AES DOMINICANA 40 41
In 1997 the capitalization process began. It was instituted due to serious
problems in the electricity market caused by a deficit in energy generation,
poor quality service and a lack of capital investment for the development of
the electricity sector.
The capitalization process was formalized in June 24, 1997, with the
publication of the State Companies Reform Law. Before this process,
generation, transmission and distribution assets in the Dominican Republic
were owned by CDE, who by law, was the only entity authorized to operate
in the electricity sector.
In the mid-90s, CDE signed several power purchase agreements contracts
with independent power producers (IPP); increasing the system installed
capacity with private capital investment. During this period, the sector was
regulated by a series of administrative resolutions, issued by the Industry
and Commerce Ministry.
Through the different stages of the capitalization process, the assets held
by CDE were divided into eight state-owned companies: CDEEE, a parent
holding company; three distribution companies: EDENORTE, EDESUR and
EDEESTE; three generation companies: HAINA, ITABO, HIDRO; and the
power transmission company ETED.
In 1999, the three distribution companies and the two thermal generation
companies were capitalized through the sale of 50% of the stocks to private
investors. The Dominican Government remained with 49% of the stocks
and the last 1% was sold to the employees of these companies.

In July 2001, the Electricity General Law was issued, establishing the institutions
of the sector and the rules under which it will operate. In July 2002, the Electricity
General Law Rulebook was issued, completing the electrical sector’s new
legislation.
In 2007, law number 186-07 modified the Electricity General Law and its
Rulebook. The new law’s goal was to penalize electrical fraud and establish other
measures to obtain the electrical sector’s financial viability.

STATISTICAL REPORT 2013AES DOMINICANA 48 49
The Empresa de Transmisión de Eléctrica Dominicana is a state-owned company with the primary objective of
building, operating and sustainably managing the grids and substations of the electric interconnected system of the
Dominican Republic, in order to provide quality 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 the North Zone with the area of Santo Domingo, is the most economically important and
functional one. It has a length of 129.9 km at a maximum transmission power of 1200 MVA per circuit. In addition,
the National Transmission System consists of approximately 2660.93 km of transmission lines at 138 kV and can be
referred to as the Sub-backbone network; also 1933.13 km of 69 kV lines. It operates and maintains approximately
85 substations, owned and shared.
Because of its radial configuration, 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, Pizarrete in the Southern Zone, Bonao II and Canabacoa in
the Northern Zone and San Pedro II in the Eastern Zone.
Three distribution companies manage the electricity distribution of the national interconnected grid:
EDESUR Dominicana, S. A.
EDENORTE Dominicana, S. A.
Empresa Distribuidora de Electricidad del Este, S. A.
These companies supplies their energy from the National Interconnected Electric System through high voltage bus bars,
which are later transformed to lower tensions levels and then conducted through each company’s grids within their zones
of concession until these reach their final users.
The distribution company (DISCOS) electricity lines within the national DISCOS grid count with an automatic load
shedding mechanism, implemented in several circuits and substations dedicated to operate in low frequency and
low voltage situations, which disconnects the electrical load automatically through different stages. This mechanism is
reviewed and updated periodically by the Coordinator Organism of the system, the independent market operator.
Distribution
TransmissionThe following table indicates the monthly energy balance during 2013. This includes the net energy injections of
the generation companies as well as the distribution companies and non-regulated users withdrawals; the last two
have been grouped independently from the generation companies with which they have a power supply contractual
arrangement.
In 2013, the total injection of electrical energy in the system was 13,850.9 GWh. The companies who supplied the
most were AES Andres with 15.2%, HIDRO with 13.4%, EGEHAINA 12.6%, ITABO S.A. with 12.3%, SEABOARD 9.6%
and DPP with a 9.2%. AES Dominicana units as a group contributed 36.6% of the energy in the Electricity Wholesale
Market, reaching the highest market share in the generation sector.

System Maximum DemandThe system’s maximum demand represents the highest power consumption on a giving hour. Generally, this happens during system
peak consumption hours between 18:00 and 22:00 hours of the a giving day. The Maximum demand data is use to recalculate the
real capacity consumption of the evaluated year; because a preliminary estimated maximum demand is used prior to computing
these figures. The system remunerates only the maximum capacity effectively recorded as demanded during the year. The following
table shows 2013’s monthly power production and power consumptions during system peak hours.
On 2013 de maximum demand occurred on May 13 at 21:00, registering a value of 2,148 MW. On this giving date, the net power
withdrawn was 2,024 MW from where the 83.5% of the withdrawn where registered to the distribution companies, 16.3 % to Non-
Regulated Users and a 0.2% generators Auxiliary withdrawn.

The short-term marginal cost is the variable cost necessary to produce an additional unit of energy considering the demand and
generation park available. The next graph presents 2013’s maximum and average monthly spot price.
Energy Spot Price
These price comparisons must be in American dollars since energy’s marginal cost is determined by the production costs of power
generation companies, whose fuel prices are acquired in the international market, which are in American dollars. Attached are the
exchange rates in dollars that were used for this report.

STATISTICAL REPORT 2013AES DOMINICANA 64 65
BUS BAR: Point or node of the electrical system prepared to
deliver and withdraw electricity.BTU:
BTU: British Thermal Unit of measurement. It is a unit of heat in the
English European System. Its equivalent in the International System
(IS) is the Calorie. The prices of Natural Gas are usually expressed in
US$/MMBtu. 1 BTU is equivalent to 252 Calories (Cal).
CONTRACTS MARKET: The market for transactions of
sale and purchase of electricity based on freely negotiated
contracts for supply.
COMBINED CYCLE: a machine composed of two phases: one
phase of gas and the other phase of steam. Typically the whole
entity consists of a gas turbine, a heat recuperation boiler, a
steam turbine, and one or several electrical generators.
FIRM POWER: The power that can be supplied by each
generating unit during peak hours, with a high level of
security/safety.
FREQUENCY REGULATION: Actions necessary to maintain
frequency within the permissible tolerances defined for the
system. The OC establishes the 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 at atmospheric pressure, Fuel Oil is used as a fuel
for electrical energy plants, boilers, and ovens.
Glossary
GAS TURBINE: A machine composed of an air compressor,
a turbine especially designed for this purpose, and an
electrical generator. The turbine converts thermal energy from
fuel, which is produced as a result of the expansion of hot gases
from the explosion of the mixture of compressed air, fuel, and
flame, into mechanical energy that is used by the electrical
generator to produce electricity.
HYDRAULIC TURBINE: A machine that uses kinetic energy
and power from water to produce a rotation movement
which, transferred through an axis, directly moves a machine
or generator that transforms mechanical energy into electrical
energy.
LIQUID NATURAL GAS (LNG): Natural Gas processed to be
transported in liquid form. It is the best alternative for transporting
and storage because when transformed into liquid as atmospheric
pressure and –163º C , the liquefaction process reduces the volume of
gas by 600 times.
MARGINAL CENTRAL UNIT: This refers to the generating
unit or units, which at optimum load dispatch increase
their generation when the demand is marginally increased.
MARGINAL SHORT-TERM COST: The variable costs necessary
to produce one additional unit of energy, considering the demand
and the generation infrastructure available.
MAXIMUM ANNUAL DEMAND: The maximum gross half our
demand, during a calendar year, of the total of the generator units
of the system, occurring within the system´s peak hours.
NATURAL GAS (NG): A mixture of gases that is
frequently found in fossil beds, alone or accompanied
by oil. It is composed mainly of methane in quantities greater
than 90 to 95%, and in addition, usually contains other gases
such as nitrogen, ethane, CO2, and traces of butane or
propane, as well as small proportions of inert gases such as
carbon dioxide and nitrogen.
NON REGULATED USER (UNR): A user of the
electrical service whose monthly demand exceeds
the limits established by the Superintendency in order
to be classified as a public user, and who fulfills the
requirements established in the Regulation of the General
Electricity Law.
OWN CONSUMPTION: The energy consumed
by the auxiliary systems of a central unit or
Substation.
PEAK POWER: Maximum power on the annual load
curve.
PRIMARY FREQUENCY REGULATION (PFR): Power
that a generator unit can vary by automatic action of its
system in the face of changes in the system’s frequency.
RIGHT OF CONNECTION: The difference between
the total annual cost of the transmission
system and the right of use estimated for the year. The
procedure to determine the right of use is established in the
Regulation of the General Electricity Law.
SECONDARY FREQUENCY REGULATION (SFR):
Power which a generator unit can vary, or modify, by
automatic or manual action of its system of regulation in a
sustained manner.
SPOT MARKET: The market for transactions of short-
term sale and purchase of electricity not based on term
contracts where economic transactions are performed at
Marginal Short Term Energy Cost and at Marginal Power
Cost.
STEAM TURBINE: A machine that transforms thermal
energy from fuel into mechanical energy. Through a process
of generation of steam produced in a boiler, which creates
conditions of high temperature and pressure. The kinetic
energy of the steam is used by the turbine to mechanically
generate electricity.
VARIABLE PRODUCTION COST OF A THERMAL
ELECTRICAL MACHINE: This corresponds to the
cost of fuel placed in the plants, and used in the production
of electrical energy, multiplied by the average specific
consumption of the machine plus the variable non-fuel cost.
