Pioneered Korea’s first ESS project in 2009, securing a global track record of over 1GW / 2.5GWh across Korea, the US, Asia, and Africa.
We provide tailored ESS designs customized to diverse
requirements, including renewable energy integration and frequency regulation.
Based on power conversion and energy operation technology, We leads the development of ESS technologies and markets around the world.
We provides the full range of service, from system consulting services to supply and integration. Equipped with strengths in the ESS business due to its extensive business experience and product reliability, Hyosung contributes to maximizing customer value and creating new future values in the electric power industry. ESS can be applied to peak shaving, frequency regulation, and renewable energy integration, and it is also used in microgrids, replacing diesel generators in remote island and desert regions.
Peak Shaving
| Discharge time | ≥ 2hours | Major customers | Consumers and DR operators |
| Purpose | ・Securing profits by charging when electricity rates are low and discharging at peak times ・Peak shifting Consumers ・Reduced electricity bills |
||
| Anticipated Benefits | Grid operators ・Elimination of concerns about power shortages at peak times ・Reduced investment costs for additional power plant construction |
||
Frequency Regulation
| Discharge time | 30 min to 1 hr (Frequency Regulation) | Major customers | Power generation business operators |
| Purpose | ・Grid auxiliary services: Providing backup power in case of emergency ・Improved power quality: Frequency regulation for generated power Power generation business operators ・Improved efficiency of existing generators |
||
| Anticipated Benefits | Grid operator ・Stable system operation with short response time ・Improved quality of power used |
||
Renewable Integration
| Discharge time | 3〜4hr | Major customers |
Renewable Energy Power generation business operators |
| Purpose | ・Power energy supply at peak demand times (REC weight margin) ・Wind and solar power output variation control ・Deferred investment in the expansion of grid transmission capacity Renewable energy power generation operators ・After storage, additional profits gained leveraging REC weight margin |
||
| Anticipated Benefits | Grid operators ・Elimination of system instability ・Control of power waste and power shortages to reduce overall system operating costs |
