SaskPower has recently launched its first utility-scale battery energy system, known as BESS, which is located at the SaskPower Fleet Street substation in Regina. This system is designed to store surplus renewable energy until it is needed, providing added flexibility to the provincial grid and supporting SaskPower’s net-zero greenhouse gas emission efforts. With the capacity to provide 20 megawatts of power to the grid, BESS can power up to 20,000 homes for one hour, ensuring a reliable energy supply for the region.

The Benefits of BESS

One of the key advantages of BESS is its ability to respond quickly to short-term power fluctuations, making it a valuable asset on the grid during times of high demand. Unlike conventional generating units, battery storage offers greater flexibility and efficiency in managing energy supply, helping to stabilize the grid and ensure a steady flow of electricity to consumers. Additionally, BESS allows for the integration of more renewable energy sources into the grid, paving the way for a cleaner and more sustainable energy future.

Enhancing Grid Resilience

By incorporating BESS into its energy infrastructure, SaskPower is taking proactive steps to enhance the resilience and reliability of the provincial grid. In the event of unexpected outages or disruptions, BESS can provide backup power to critical facilities and help maintain essential services for residents. This added layer of resilience ensures that the grid can withstand unforeseen challenges and continue to meet the energy needs of the community.

Supporting Sustainability Goals

As part of its commitment to reducing greenhouse gas emissions, SaskPower is leveraging BESS to support its sustainability goals and transition to a low-carbon energy system. By storing surplus renewable energy and optimizing its use during peak demand periods, BESS plays a pivotal role in reducing the reliance on fossil fuels and mitigating the environmental impact of energy generation. This innovative approach to energy storage aligns with SaskPower’s vision for a greener and more sustainable future for Saskatchewan.


The launch of SaskPower’s utility-scale battery energy system marks a significant milestone in the province’s energy transition journey. By harnessing the power of BESS, SaskPower is not only enhancing the reliability and resilience of the grid but also advancing its sustainability objectives and reducing its carbon footprint. With BESS in operation, SaskPower is well-positioned to meet the evolving energy needs of the community while contributing to a cleaner and more sustainable energy landscape for future generations.
