BESS serves as a linchpin on the path towards renewable transition. It allows for excess electricity generated by renewable sources, such as solar or wind, to be stored and used during peak demand, periods of low to no resource generation, or network instability. As variable renewable energy (wind and solar) provides a large share of the energy generation, the value of energy storage in maintaining a balanced power grid becomes paramount. Thus, BESS secures a stable power supply despite the intermittent power production of renewable sources.
The use of BESS also promotes carbon accounting’s main goal of reducing carbon dioxide emissions. By maximising the use of renewable sources and decreasing dependence on fossil fuel-powered electricity, these systems significantly reduce carbon emissions, further mitigating the impacts of climate change. At a site-specific level, companies can leverage BESS to manage their carbon footprint effectively, integrating renewable energy into their operations and ensuring network reliability at the same time.
Moreover, it contributes to power grid resilience. In the event of power outages, BESS provides emergency backup power, ensuring energy security to critical infrastructures like hospitals, financial institutions, and data centres. Furthermore, BESS can offer peak shaving capabilities, reducing demand on the power grid during periods of high electricity use, thereby assisting in grid stability and reducing energy cost.
Thus, BESS stands as an integral part of the renewable energy landscape, assisting in bridging the gap between intermittent renewable generation and consistent power supply requirements. Through maximizing usage of renewable resources and enhancing power grid resilience, Battery Energy Storage Systems further make green energy an increasingly viable and reliable energy solution.
