Battery Energy Storage System (BESS) operation and maintenance
At Solarig, we provide operations and maintenance services for battery storage systems — Battery Energy Storage Systems (BESS) — a key technology for accelerating the energy transition and facilitating the integration of renewable energy sources into the grid.
Energy storage for a more flexible, efficient and resilient energy system
Storage enables the management of variability in renewable generation, provides stability to the electricity system and optimises the value of energy in increasingly dynamic markets.
Solarig works with standalone and hybrid BESS solutions, designed to provide flexibility, reliability and services to the electricity system. We combine targeted development, technological partnerships and long-term capabilities to operate and optimise BESS assets on an international scale.
An international platform for large-scale operations
An integrated BESS strategy to create long-term value
The performance of a BESS asset does not depend solely on its availability. Conversion efficiency, degradation, response times, safety and compliance with warranty conditions all have a direct impact on the value of the investment. Solarig combines its experience as a developer, its technological partnerships as a contractor and its in-house operations and maintenance capabilities to support owners and integrators throughout the asset’s life cycle.
Tailored operations
We adapt to each project’s operating and billing models and to the O&M periods required by each BESS market. We establish night and weekend on-call cover, schedule preventive maintenance outside planned operating windows and maximise BESS asset availability 24/7.
Integrated model
We combine our team’s capabilities and project-specific instructions with market best practice and, above all, partnerships with manufacturers and integrators to optimise BESS systems throughout their operating life.
Safety is our priority
BESS projects involve additional risks associated with heavy loads, gases and fires “Thermal runaway” and high temperatures, requiring specific operating, maintenance and intervention expertise. We invest in digitising individual cell status through alarms and Health Check analysis, Health Check, equipamos con ropa, EPIs, herramientas y vehículos con los more altos estándares de la industria.
Long-term commitments
We have a scalable international platform ready to operate and optimise BESS assets worldwide, protecting availability, revenues and asset life through stable relationships and locally delivered capabilities backed by global expertise.
An integrated view of every asset system
Solarig covers the key subsystems that make up a BESS installation, from batteries and control units to auxiliary systems and high-voltage electrical infrastructure. This scope enables the coordination of work across different technologies, manufacturers and configurations.
Capability to operate and maintain ESS systems, modules, racks and containers, together with battery management systems (BMS), cooling, fire protection and safety systems.
Four technical areas.
Supervision, operation and maintenance of PCS, PPC plant controllers, BMS, communications systems and metering and control equipment.
Management of transformers, switchgear, substations, medium- and high-voltage equipment, HVAC, fire protection, safety and other balance-of-plant elements.
Experience with standalone BESS systems and projects integrated with solar or wind generation, adapting operations to different manufacturers, technology configurations and use strategies.
Operation and maintenance services for BESS assets
Solarig combines 24/7 remote operations, field intervention capability and technical coordination with manufacturers and integrators to cover the asset’s key needs and protect warranties, revenues and useful life.
Operate and respond
- Continuous control 24/7 operation, remote control and monitoring of asset and cell health.
- Incident management Supervision, prioritisation and response to alarms and incidents.
Maintain and protect
- Integrated maintenance Preventive, corrective and predictive maintenance, including retrofit interventions.
- Critical infrastructure Maintenance of auxiliary systems, safety systems and medium- and high-voltage equipment.
Optimise and coordinate
- Performance and KPIs Monitoring of availability, efficiency and degradation, energy retention and throughput.
- Technical coordination Operational relationship with manufacturers, owners, traders and technology partners.
Digitalisation to protect BESS performance and asset life
Solarig integrates control centres, real-time monitoring, digital maintenance management and performance analytics to turn BESS system data into operational decisions. This approach helps detect deviations, coordinate the technical response and provide owners with traceable information on availability, efficiency, degradation and asset evolution.
Cyber-secure control centres
They monitor alarms and the status of controllers, BMS, PCS and storage systems in real time, enabling remote diagnosis and a coordinated response.
Custodian: integrated SCADA and CMMS
Real-time information, work orders, procedures and intervention history connected in one operational environment.
Analytics and reporting
Real-time automated KPIs and reporting to support coordination with owners, manufacturers, integrators and market participants, document asset behaviour and prioritise technical and economic actions.
BESS operations in strategic markets
Solarig’s references in Chile and Australia demonstrate its ability to operate BESS systems in advanced markets, work with leading manufacturers and adapt the service to different technologies and configurations.
A key market for the growth of BESS
Chile is one of the most dynamic markets for energy storage, driven by its high penetration of renewables and the need to provide flexibility to the electricity system.
With more than 10 years’ experience in Chile and more than 2 GW under management in high-voltage, photovoltaic, wind and BESS assets, Solarig is consolidating its role as a leading partner in a key market for the energy transition in Latin America.
From Yadlamalka to a global O&M platform
Australia was one of the first markets where Solarig began its energy storage operations with the Yadlamalka project, which combines solar generation with a vanadium flow battery of 2 MW / 8 MWh.
The project enabled the development of specialised technical skills in an advanced and highly competitive market.
Solarig currently manages over 2 GW in O&M in Australia and continues to expand its expertise in energy storage.
Un mercado clave para el crecimiento del BESS
Chile es uno de los mercados más dinámicos para el almacenamiento energético, impulsado por su elevada penetración renovable y la necesidad de aportar flexibilidad al sistema eléctrico.
Con más de 10 años de experiencia en Chile y más de 2 GW gestionados en activos de alta tensión, fotovoltaicos, eólicos y BESS, Solarig consolida su papel como socio de referencia en un mercado clave para la transición energética en Latinoamérica.
De Yadlamalka a una plataforma global de O&M
Australia fue uno de los primeros mercados donde Solarig inició su actividad en almacenamiento con el proyecto Yadlamalka, que combina generación solar con una batería de flujo de vanadio de 2 MW / 8 MWh.
El proyecto permitió desarrollar capacidades técnicas especializadas en un mercado avanzado y altamente competitivo.
Solarig supera actualmente los 2 GW en O&M en Australia y continúa ampliando su experiencia en almacenamiento.
