01. Cogeneration

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 high 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.

02. Solar Power Generation

Solar power generation converts solar energy to electricity. In the recent years,
countries around world have formulated various policies to promote this new rising sector.

태양의 빛 에너지를 태양광 모듈에서 접속함, 인버터, 변압기, 배전반, 변전소, 전력계통을 지나 전기 에너지로 공급
  • 태양광 흡수
  • 전하생성
  • 전하분리

As part of diversifying our energy business, we are promoting our solar power generation business on the national/domestic level and also on the overseas level. We are also expanding our solar business scope from power generation to project development, O&M, system solution business and others. In Japan, we operate several solar power plants with a combined capacity of 36MW including a 24 MW scale solar power plant in Oita. We are planning to continuously expand the scale of our business.
Also in Turkey and India, we are planning to construct a 42MW and a 152MW solar power plant respectively, and commence commercial production in 2017. We are also developing several solar power projects in California, Texas, Las Vegas, etc.

In addition, we are promoting the expansion of smart energy business model based on energy system solution.
To achieve this goal, we are conducting business such as servicing central control systems for distributed renewable energy power sources,
establishment and operation of solar/wind power connected ESS, and microgrid business for areas with vulnerable power infrastructures.
We have recently transformed Chungcheongnam-do Jukdo Island into an energy self-reliant island by applying the latest related technologies.

04. Energy Solution

We construct and supply the most efficient system possible by analyzing the data of ESS applications, such as power generation and energy usage. We maximize customer value with integrated solutions, including efficient and stable product configuration and engineering, professional system-building and stable operation and management.

  • Ess for Renewables Integration
  • To ensure more stable power, we link ESS to less stable renewable power grids such as solar and wind.
  • Commercial and Industrial ESS provides an ESS system for facilities with time-of-use (TOU) that harnesses low-cost night time power during high-cost peak hours.
  • Ancillary Service ESS stabilizes power quality by responding quickly to fluctuations in frequency and voltage caused by unstable power supply and demand.
  • Microgrids
  • We supply power through renewable generation and manage energy consumers in the community. We provide self-sufficient power network building and operation services, from generation to consumption.

06. New Energies

Independent Power Generation Business
Hanwha Energy is developing power generation business opportunities in countries with high power demands
and business environments suitable for Independent Power Producer (IPP) business.
An IPP participates in the power industry of a country by constructing a power plant and supplying electricity
based on the long term Power Purchase Agreement (PPA) signed with a local power company.

IPP business can largely be divided into two types of businesses. Generation business focuses on electricity
generation while Group Energy business generates and supplies electricity and steam to companies within
an industrial complex.
Group Energy business
  • Electricity produced by an IPP is either supplied to
    the local power company or companies within an
    industrial complex. In addition, steam produced
    by an IPP is supplied to companies within
    the industrial complex.
Generation Business
  • Electricity produced by an IPP is supplied to
    the local power company under the PPA agreement. PPA : Power Purchase Agreement
    Hanwha Energy will expand its generation business
    overseas by capitalizing on business opportunities
    in nations with positive IPP business potential.
