We build plants but internally, across our solar value chain, from development to operations to sales, we're also learning and building on what we know in solar energy. And by partnering more closely with our vendors, landowners, investors and communities, we've been able to better capture the common needs that became our requirements for our solar power plants that in turn, have helped our customers reach their goals faster with better economies of scale. Our solar power plants are designed to be catalysts to deliver reliable, clean, and affordable solutions for communities around the world.
is expanding its global footprint to meet the growing needs of our customers around the world. Bringing deep field experience to every project, we will create another success story moving forward.
Solar energy is a clean resource for generating low-carbon electricity. Building on our long history in the solar power industry, we are now providing high-quality energy to homes around the world.
In the U.S., the world??s largest solar energy retail market, we are emerging as an industry leader by securing and expanding business opportunities. In December 2018, we completed the 236MW Midway solar power plant in Texas. We were also awarded with a major solar energy contract by Hawaiian Electric Company in January 2019. Under the PPA (Power Purchase Agreement), we were awarded with a contract for a 489MW solar power plant and a 504MWh ESS. Starting from 2019, we have been operating a 134MW solar power plant and a 4MWh ESS.
And since 2022, a 364MW solar power plant has been in operation. In addition to the solar power generation business, we entered the energy retail market in July 2019 in the city of Houston. Since our launch, we accrued 18,000 customers as of the end of 2019, and reached 30,000 customers by June 2022. Through our energy retail brand, Chariot Energy, we are able to differentiate ourselves with an omni-channel based customer service offering, as well as transparent and affordable service plans.
Hanwha Energy Retail Australia Pty. Ltd. (trading as Nectr) publicly launched its electricity retail business on February 2020 with the mission of building Australia??s first ??Digital Gentailer?? that will deliver brilliantly simple solutions for our customers for a better life. Nectr will achieve this by building the business from ground up that is purpose built for the new energy market and delivers competitive advantage and differentiation across the energy value chain. The Australian energy market is going through a period of change unlike any other its recent history. New technologies, rapidly changing policy frameworks, rising energy costs, and ongoing levels of customer frustration all combining to drive the emergence of new energy business models. Nectr has an exciting opportunity to take advantage of the disruption that is occurring in the Australian energy market and establish itself as a leading player in the new energy environment. Nectr aims to fundamentally change the competitive landscape and by doing so restore the trust between customer and energy provider that has been eroded over time.
In addition to the solar energy generation, we are also launching an energy retail business to expand our solar energy value chain in Spain. In September 2019, we established a subsidiary for our retail business in Madrid, Spain. And in October 2020, we launched Imagina Energia??our official energy retail brand. Through Imagina Energia's businesses, we provide green, affordable and innovative products and services for B2B and B2C customers in Spain. Using our expertise in solar energy, we are also in pursuit of a retail business connected to distributed generation, such as rooftop solar energy. Electricity is generated by rooftop solar panels during the day and is drawn from the grid at night. These rooftop solar panels enable customers to self-consume renewable solar energy, saving electricity bills and being more eco-friendly.
Cogeneration is the improvement of energy utilization by simultaneously producing electricity and steam.
Hanwha Energy is contributing to the enhancement of competitiveness of the companies in the Yeosu National Industrial Complex and
the Gunsan 2nd National Industrial Complex by stably supplying good quality steam and electricity at low prices.
We are actively participating in the national policy for efficient energy utilization and saving through stable supply of utilities and
the implementation of highly efficient eco-friendly systems based on the latest technologies.
Industrial water is received and stored in water tanks. Water for high-pressure boilers is produced and supplied
through the water treatment process consisting of the removal of floating materials, activated carbon filter,
ion exchange resins, and MBP.
The bituminous coal is transported from the Gwangyang port to the Yeosu and Gunsan plants by trucks.
Then it is stored in the coal silo and fed into the boilers through a conveyor belt system.
The coal is supplied to the combustion furnace filled with the bed materials (sand, ashes) and the combustion
air is supplied at a high speed through the distribution plate at the bottom while the particles circulate in floating state.

This device electrically captures dust by passing exhaust gas through the layers of the ESP system to prevent the discharge of
dust to the air. This helps to minimize air pollution.
This device produces rotational force through impulse and reaction using the flow of compressive fluids
(gas, steam).

This device changes the voltage of alternating current or the current value using electromagnetic induction.
This is a heat exchanger that cools water by direct contact with external air to reuse the cooling water for
the condenser.
In collaboration with HDC, we are constructing a 1,012MW LNG power plant and a 200,000kl storage tank in Tongyeong, South Korea. In 2022, Hanwha Energy successfully executed a long-term LNG sales and purchase agreement with a global major LNG supplier. The committed LNG will be supplied to the CCPP in Tongyeong, which is expected to start commercial operation in 2024. Using LNG for power generation is an important and necessary stepping stone to realizing our vision to power the world.
To expand our business into global energy market, we formed a consortium to execute the construction project of combined gas power plants and LNG terminal in Vietnam. Our goal is to successfully complete the project and supply the gas power plants with competitively priced LNG. We will operate and manage the gas power plants, once they're built.
We finished construction of a 50MW scale hydrogen fuel cell power plant in the Daesan Industrial Complex and started commercial operation from June 2020.
