ESS Industry: Transforming the Power Paradigm
ESS Safety Monitoring, Powered by Qlight
With growth in the electric vehicle (EV) market slowing, global battery manufacturers are shifting their focus to the
ESS (Energy Storage System) market.
As renewable energy expands and demand for power grid stabilization increases,
ESS is rapidly emerging as a next-generation core growth sector.
The era of “producing electricity and using it immediately” is coming to an end.
Technologies that store surplus electricity and utilize it efficiently are now at the center of national energy strategies.
This is where ESS (Energy Storage System) plays a critical role.
ESS acts as an intermediate storage hub connected to the power grid,
bridging the time gap between power generation, storage, and consumption.
Previously limited to peak-load support, ESS has evolved into a key system
that stabilizes power quality when integrated with variable renewable energy sources such as solar and wind.
The Electric Vehicle Market Enters the Chasm Phase
• Rising battery raw material prices → Increased manufacturing cost burden
• Insufficient charging infrastructure and weakening consumer demand → Stagnating sales growth
• Reduced investment and production adjustments by global OEMs → Declining battery demand
Why the ESS Market Is Gaining Momentum
• Grid stabilization: An essential partner for intermittent renewable energy sources such as solar and wind
• Emergency power supply: Growing demand for stable power in data centers, hospitals, and semiconductor plants
• Regulatory and policy support: Governments worldwide mandating ESS installations to achieve carbon neutrality
• Improved economics: Peak-load reduction and electricity cost savings driving investment incentives
Market Outlook
• Global ESS market projected to grow at a CAGR of 25–30%, reaching several hundred GWh by 2030
• The Korean ESS market is also expected to maintain strong growth, driven by renewable energy expansion and rising public and industrial demand
• B2B customer shift: Core demand transitioning from automotive to data centers, factories, and energy companies
What ESS Requires Is “Visualized Safety”… Qlight’s Solution
Qlight has established itself as an “energy safety signaling partner”,
providing both visual and audible indication of key equipment status within ESS facilities
and immediately alerting on-site personnel or remote operators to potential hazards.
ESS facilities consist of multiple power components such as
PCS (Power Conditioning System), BAT (Battery Racks), and EMS.
Visualization devices are an essential element for integrated control across these systems.
Qlight applies a wide range of technologies—including wireless control, remote alerts,
high-brightness LEDs, and voice warnings—optimized for ESS environments.
In the ESS sector, Qlight’s QPL and QEL series lighting solutions
are already supplied to global companies such as BYD, proving their reliability and quality.
