ESS

ESS efficiently stores and manages energy.

ESS FR (ESS for Frequency Regulation)

Frequency Regulation Energy Storage System(ESS for Frequency Regulation, ESS FR) responds to instantaneous frequency changes in the power grid.
ESS controls charging and discharging to maintain the grid frequency stable at 60 Hz.

ESS FR Advantages

Ultra-Fast Response (0.2 sec)

Stabilizes the grid instantly during
sudden frequency changes.

Lower Operating Costs

Reduces reliance on standby generators and fuel expenses.

Eco-friendly System

Controls electricity quality without emissions.

Automated Control

Smart operation via EMS.

Industrial Scalability

Integrates batteries, EMS, PCS, and other systems for industrial synergy.

Long-Duration Energy Storage (LDES)

Long-Duration Energy Storage (LDES) systems can store and supply electricity continuously for over 6 hours. Compared to conventional short-duration ESS (which stores energy from minutes to a few hours), LDES provides longer-term storage and reliable power delivery,
making it an essential technology for renewable energy-based power grids.

Key Needs and Roles of Long-Duration ESS

Addressing Intermittency of Renewable Energy

LDES is crucial for compensating the intermittency of solar and wind energy, which varies with weather and time.
It can store electricity generated during the day for use at night or ensure stable power supply even on windless days.

Enhancing Grid Stability

By bridging the gap between electricity demand and supply, LDES stores surplus energy and delivers it during peak periods,
improving the stability and efficiency of the power grid.

Enabling Carbon Neutrality and Energy Transition

LDES reduces reliance on fossil fuels and plays a key role in maximizing the practical use of renewable energy,
supporting the transition to a sustainable, renewable-based power system.
