03Providing a Steady Supply of Energy

Combining Eco-Friendly
Wind Energy with a High-Efficiency ESS

Providing a Steady Supply of Energy
despite Wind Fluctuations

The ESS marks the beginning of
the expansion of new and renewable energy

On November 4, 2016, the Paris Agreement went into effect. The aim of this agreement, signed by 197 parties to the United Nations Framework Convention on Climate Change (UNFCC), is to reduce greenhouse gas (GHG) emissions in order to prevent the average global temperature from rising beyond 2℃ above pre-industrial levels. Experts believe that the agreement will play an enormous role in promoting the use of clean forms of energy, namely wind and solar power systems, which produce no greenhouse gases.

Although they are eco-friendly, wind and solar power systems are inherently unstable, as the energy they supply undergoes large
fluctuations with changes in sun exposure and wind speed. The solution to this problem is the energy storage system (ESS). An ESS is a convenient and efficient way of storing and supplying energy on an as-needed basis, thereby compensating for the fluctuations in the wind and solar energy supplies.

An ESS stores the energy that is generated on windy or sunny days, and then supplies that stored energy on days that are calm or cloudy. For this reason, the ESS is vital to the sustainability and continuous development of renewable energy sources.
The International Energy Agency (IEA) estimated that renewables’ share of total global electricity generation will grow from 23 percent
in 2015 to 28 percent by 2021. Industries expect that, as climate change continues, ESS development will stimulate the growth of
renewable energy industries.

Installation of an ESS for
a wind power generation system on Jeju,
aiming to harness the island’s strong winds

Located in the waters southwest of Korea, Jeju Island is the nation’s largest island. A global tourist attraction, the island is also known for its strong winds. LG, with the help of some of its technologically advanced affiliates, is currently conducting a 27-megawatt-hour ESS project on Jeju that is expected to become the largest energy generating facility on the island.

LG CNS, which is in charge of the project’s installation and operation, is known for its integrated approach to installing and operating energy systems. Over the next 15 years, LG will contribute to the efforts to reduce Jeju Island’s carbon footprint and restore and preserve the island’s natural environment.

In particular, LG CNS will combine the ESS of LG Chem with the world-renowned technology and power conditioning system (PCS) of LG Electronics. A PCS is a device that converts electricity from one form to another. The PCS used for this project will convert the alternating current produced by wind turbines to a direct current that can be stored using an ESS and supplied through a power system when needed.

LG contributes to growth of new and renewable energy
through verified ESS solution

Leveraging its PCS and battery storage technology, LG CNS has positioned itself as the leading Korean company in the ESS market. In 2015, Navigant Research, an American market research agency, ranked LG CNS as the top company in Asia and fourth worldwide in terms of ESS and system integration (SI) technologies.

With its verified ESS solution, LG stands at the frontlines of the global effort to create a better future by expanding the use of renewables and reigning in the rise in the global temperature.
