What are Battery Energy Storage Systems?
Battery energy storage systems are cutting-edge technologies designed to store electrical energy for later use. These systems play a pivotal role in modern energy management by storing excess power generated during periods of low demand and dispatching it during peak usage times.
This capability maintains the balance between energy supply and demand, strengthens grid stability, and supports the integration of renewable energy sources like solar and wind which are intermittent and can be smoothed out with battery storage.

The Advantages of
Battery Energy Storage Systems
Cost Savings
By optimising power usage and leveraging smart technology, SustainStorage™ systems reduce energy expenses and maximise your return on investment. These savings are achieved through more effective energy management practices such as peak shaving, which reduces reliance on peak-time grid electricity.
Dependable
Each battery energy storage system is engineered to perform reliably in the most demanding environments, from extreme heat to cold. This means your energy needs are met consistently and without interruption.
Global Compliance
We strictly adhere to quality management protocols and maintain compliance with internationally recognised standards, including ISO 9001 for quality management systems, SABS (South African Bureau of Standards), and SANS (South African National Standards).
Environmental Responsibility
Sustain Storage™ units contribute to reducing your carbon footprint. Our systems promote sustainable energy practices by facilitating greater use of renewable energy and decreasing dependence on fossil fuels.
Scalable and
Flexible
We can deploy our battery energy storage systems in various sizes and configurations to meet specific energy needs, from small commercial businesses to large utility-scale projects.
Energy Finance Solutions
We recognise that investing in energy storage solutions is a significant commitment. That's why we offer customised financing options to make our Sustain Storage™ solutions more accessible to businesses and organisations of all sizes.
Let’s work together to create flexible payment plans that match your cash flow and business objectives.
Operations & Maintenance
The longevity and efficiency of any battery energy storage system depends on its maintenance. SustainPower's comprehensive operations and maintenance (O&M) services ensure that your Sustain Storage™ systems operate at peak efficiency with minimal downtime.
With our support, your energy storage investment can deliver value year after year.
