Grid BESS
Grid Battery Energy Storage Systems (BESS) are usually positioned in front of the meter as they are connected at the distribution or transmission level, injecting power directly into the electricity grid. They play a critical role in today’s energy market.
Brunstock’s energy blocks are engineered to store vast amounts of energy, measured in megawatt-hours (MWh), which can be dispatched to the grid as needed. This capability is crucial for managing the intermittent nature of renewable energy sources like solar and wind, which can produce surplus energy during peak production times.
By storing this excess energy, grid BESS ensure a consistent and reliable supply of electricity, even when renewable generation is low.

Scalable utility storage built from modular 5MWh BESS units
Brunstock’s 5MWh BESS unit is the building block for projects of any scale. Three BESS units deliver 15MWh; twenty-four deliver 120MWh, sized to your requirements, not fixed configurations.
We also include the necessary step-up stations for our BESS. These include components like a transformer, SF6-free switchgear and a power conversion system (PCS).
Brunstock supplies battery energy storage systems to support grid stability. These systems absorb energy during low demand and release it during peaks, balancing supply and demand and reducing blackout risk.
Large-scale storage capacity makes grid BESS ideal for reserve power, grid support services and enhancing network flexibility.
Massive capacity
Our grid BESS are designed to handle substantial amounts of energy, measured in megawatt-hours (MWh). Our grid-scale energy storage solutions can be found around the world, including in Switzerland and Australia.
Our Brunstock BESS units are modular and scalable. For instance, a single utility-scale BESS installation by a Brunstock representative in your area can have a capacity of several hundred MWh, enough to power thousands of homes for several hours.
These large storage capacities allow the BESS to play a pivotal role in energy management by storing excess energy generated during periods of low demand or high renewable generation and dispatching it during peak demand times. This capability not only supports grid reliability but also enhances the integration of renewable energy sources into the grid.
By absorbing and releasing energy as needed, Brunstock’s grid BESS helps to smooth out fluctuations in energy supply and demand, thereby preventing blackouts and supporting grid stability. This technology is essential for modern energy infrastructure, ensuring a reliable supply of electricity even as we transition to more renewable energy sources.
Grid stability
Grid energy storage plays a vital role in ensuring grid reliability by smoothing out fluctuations in energy supply and demand. These systems absorb excess energy during periods of low demand or high renewable generation and release it during peak demand times. This ability to balance supply and demand helps prevent blackouts, thereby supporting a stable and reliable grid.
Renewable integration
Grid BESS are instrumental in integrating renewable energy sources into the grid. Solar and wind energy, while abundant and sustainable, are inherently variable and dependent on environmental conditions. This variability can lead to periods of surplus energy production when the sun is shining brightly or the wind is blowing strongly, and periods of low production when these conditions are absent.
Grid BESS provides a solution to this challenge by storing excess energy generated during peak production times. For instance, during a sunny afternoon, a solar farm might produce more electricity than the grid requires. A grid BESS can absorb this surplus energy, preventing it from going to waste. Conversely, during the night or cloudy days when solar production is low, BESS can release the stored energy, ensuring a consistent supply.
Similarly, wind farms often produce excess energy during windy periods, which can be stored in batteries. When the wind subsides, the stored energy can be dispatched to maintain a steady and reliable power supply. This capability to balance the intermittent nature of renewable energy sources not only stabilises the grid but also maximises the utilisation of renewable energy, reducing reliance on fossil fuels.
By facilitating the seamless integration of solar and wind energy into the grid, Brunstock BESS supports the transition towards a more sustainable and resilient energy infrastructure. This synergy between BESS and renewable energy sources is crucial for achieving long-term energy security and environmental sustainability.
