WSTOR-500kWh — WEG WSTOR Battery Energy Storage System
The WEG WSTOR Battery Energy Storage System is a utility-grade lithium iron phosphate (LFP) energy storage solution scalable from 100 kWh to 10 MWh per installation, designed for peak shaving, renewable energy integration, frequency regulation, and backup power applications across Saudi Arabia's rapidly evolving energy landscape. The WSTOR-500kWh containerised unit integrates LFP battery modules, a bidirectional power conversion system (PCS) based on WEG's CFW11 inverter technology, a battery management system (BMS), thermal management, and fire suppression in a factory-assembled 20-foot or 40-foot ISO container, enabling rapid field deployment at solar farms, substations, industrial facilities, and off-grid remote sites across the Kingdom.
The WSTOR system's bidirectional PCS converts stored DC energy to AC with conversion efficiency exceeding 97% in both charge and discharge directions, and responds to grid frequency deviations within 200 ms — fast enough for primary frequency regulation services. The LFP chemistry offers a cycle life of more than 6,000 cycles at 80% depth of discharge, equating to more than 16 years of daily cycling at Saudi Arabia's utility tariff arbitrage schedules, with no thermal runaway risk and stable performance at cell temperatures up to 55°C. The integrated BMS monitors each cell's voltage, current, and temperature at 10 ms intervals, implementing active cell balancing and protective shutdown sequences that comply with IEC 62619 lithium battery safety standards and NFPA 855 energy storage installation requirements.
Saudi Arabia's Vision 2030 target of 50% renewable energy by 2030 and the Saudi Green Initiative's 278 GW renewable capacity ambition create strong policy momentum for grid-scale energy storage deployment. SEC and NEOM are actively procuring BESS systems to stabilise solar and wind generation integration, and Aramco's Net Zero by 2050 roadmap drives demand for behind-the-meter storage at refineries and processing plants to reduce peak demand charges. The WSTOR's compatibility with SEC's grid code requirements for grid-forming inverter operation positions it for integration into the evolving Saudi electricity network. Industrial consumers can use WSTOR for demand charge management, reducing the peak demand component of SEC tariffs which can represent 30–40% of large industrial electricity bills.

Key Features & Benefits
- LFP battery chemistry provides more than 6,000 cycles at 80% depth of discharge with no thermal runaway risk, equating to over 16 years of daily cycling for tariff arbitrage applications.
- Bidirectional PCS with greater than 97% round-trip conversion efficiency and 200 ms frequency response enables primary frequency regulation services on the Saudi SEC grid.
- Factory-assembled ISO containerised design enables rapid field deployment at solar farms, industrial facilities, and remote off-grid sites without complex civil works.
- IEC 62619 and NFPA 855 compliant BMS with 10 ms cell-level monitoring and active balancing ensures safe operation in Saudi Arabia's high-ambient-temperature environments.
- Grid-forming inverter capability supports SEC grid code requirements for renewable energy integration, enabling stable islanded operation during grid outages.
- Scalable modular architecture allows capacity expansion from 100 kWh to 10 MWh by adding containerised modules to an existing installation without replacing existing hardware.
Industrial Applications in Saudi Arabia
- Grid-scale solar energy storage at PIF and ACWA Power renewable energy projects, smoothing solar generation variability and enabling time-shifting of daytime generation to evening peak demand.
- Industrial demand charge management at ARAMCO, SABIC, and MARAFIQ facilities, reducing the peak demand component of SEC tariffs by clipping consumption spikes with stored energy.
- NEOM and Red Sea Project off-grid and microgrid energy systems where 100% renewable energy targets require dispatchable storage to balance intermittent generation sources.
- SEC substation frequency regulation and voltage support services, providing fast-response reactive and active power control to stabilise the Kingdom's transmission network.
- Data centre UPS replacement and backup power, providing seamless transition from grid to stored energy with sub-cycle transfer times superior to traditional diesel generator backup.
- Remote telecom tower and monitoring station power where diesel generator replacement with solar plus WSTOR storage reduces fuel logistics costs and carbon emissions.
