HuntingtonBeach EnergyProjectThe AES Huntington Beach Energy Project (HBEP) is a

650 megawatt (MW), natural gas-fired power plant

with the capacity to power nearly one-million average

Southern California homes using the cleanest available

natural gas and best in-class combined-cycle gas

turbine technology.

Our new plant eliminates the use of ocean water for

cooling, reduces the use of fresh water by 70 percent,

uses 50 percent less fuel to generate the same amount

of electricity as the old steam boilers it is replacing, and

is fitted with the best available emission control

technology.

In addition, the HBEP’s fast and efficient start-up and

shut down capabilities will enable the integration of

intermittent renewable energy and fill the gap when

the sun does not shine and the wind does not blow,

helping California reach its clean energy goals.

AES is committed to a responsible energy transition, helping

California accelerate the growth of intermittent, renewable energy

while reducing emissions from the use of fossil fuels.

We also believe our role should extend beyond our core mission.

Which is why we are dedicated to making a positive impact in the

communities in which we live and work through our philanthropic

program.

Our philanthropy is focused in ways that address important issues

like the environment, education and training, public health and

safety, and social and cultural welfare. We believe we can

strengthen and empower our communities by collaborating with

community partners who dedicate their time to strengthen and

improve the quality of life of the residents in the communities we

serve. Because people are at the core of what we do.

The gas turbine is the heart of the power plant. Here, a mixture of compressed air and natural gas is ignited. The air/fuel mixture moves through the turbine blades making them spin. This drives a generator which converts the spinning energy into electricity.

The steam turbine uses steam to spin the generator, creating additional power.

The new plant will have state-of-the-art equipment that will use moving air to cool the steam that is used in the combined cycle system. This type of cooling system is known as “air-cooled condenser (ACC)” and it functions similarly to the radiator and circulation fans in your car. The ACC eliminates the need for ocean water to cool the steam.

The Heat Recovery Steam Generator (HRSG) captures exhaust heat from the gas turbine that would otherwise escape through the exhaust stack. The HRSG generates steam that is delivered to a steam turbine.
