Eco-friendly energy solutions for our future. Samsung SDI is leading the world market
with Lithium-ion energy storage.

ESS Business

Choice for clean earth, ESS

What do we need to do to make our earth cleaner? Energy industry has been transformed from the existing thermal and nuclear power into the green energy such as solar and wind power. In addition, many efforts have been made for efficient production and consumption of energy. This is the energy trend, from energy mass production to consumption, for smart and eco-friendly use of energy. And energy storage devices stand at the center of trend. Samsung SDI is leading the paradigm shift of future energy industry.
Samsung SDI initiated lithium battery ESS business in 2010 on the basis of world’s best technology of small-sized lithium-ion rechargeable battery. ESS, Large-size battery system, inherited full stability of our world’s best rechargeable batteries which have been used for the latest mobile devices and electric cars.

Samsung SDI’s ESS technology is able to meet various needs of the users and provides customized solutions for the various purposes of the electric power market. Our ESS provides not only economy but also strong reliability through its long-lasting life, safety and excellent performance. Spanning from the size of kWh to MWh, Samsung SDI supplies various of ESS solution – residential, utility, commercial, UPS and base transceiver station - applicable to your everyday life, leading the green energy industry.
Choice for tomorrow - Samsung SDI is creating the world of green energy with environment-friendly production of electric power and its smart use. Everywhere in the world – your home, power plant, large-sized office and mobile base station, ESS goes with your everyday life.

Advantages of our energy storage

  • 01 Samsung SDI’s energy storage provides a variety of values
    for the users.

    ESS complements the intermittence of renewable energy produced by wind or solar power generation system. ESS stabilizes the output of renewable energy by charging & discharging irregular and intermittent power which is generated from wind and solar system. Minimizing output fluctuation / Improving power quality

  • 02 ESS can greatly reduce the investment costs for
    tupgrading transmission and distribution network.

    Power storage can manages local peak demand in a smart way, deferring the point of necessary investment for transmission and distribution network.
    Supplying Power Transmission / Mitigating Excessive Power Demand Region & Frequency Control

  • 03 ESS helps grid system operators
    maintain constant frequency.

    Energy storage based on lithium ion battery provides reliable and fast frequency response without being subject to fuel prices and with zero emissions.

  • 04 ESS enables commercial and
    residential owners to cut energy costs.

    Electricity stored during off-peak time can be used during on-peak hours so that home/commercial owners can cut peak demand and electricity cost. ESS integrated with PV can maximize consumption of solar energy by using electricity stored off-peak.

  • 05 ESS can be used for curtailment of electricity
    from renewable energy sources.

    Due to transmission constraints, currently, ever-increasing portion of wind generation is being curtailed. Energy storage is the best option for reducing renewable power curtailment, relieving transmission congestion, and achieving full utilization of renewable energy sources.

Targeting micro-grid ESS market by making a partnership with ABB

Samsung SDI signed an MOU with ABB , one of the global leaders in power and automation technologies for joint development and sales of micro-grid ESS solution. It has a great significance because Samsung SDI established a foundation to make a leap to be the No. 1 in micro grid ESS market. We are going to develop and sell the optimized ESS solution using Samsung SDI‘s lithium-ion battery technology together with ABB’s power component technology such as PCS, EMS, etc.
