About Storage

Ensuring Grid Security

A grid-connected energy storage facility serves the vital purpose of guaranteeing the security of the national electrical grid. By storing electricity during surplus supply, it acts as a strategic reservoir, releasing stored energy back into the grid during periods of high demand.

Addressing Mismatched Energy Dynamics

The challenge of balancing energy supply and demand becomes increasingly prominent as intermittent energy sources, such as renewables, gain precedence over conventional forms like gas and coal. Grid-connected storage facilities are crucial in mitigating this issue by providing a reliable buffer, ensuring a continuous and stable energy flow despite the fluctuations in renewable energy generation.

Adapting to Evolving Energy Landscapes

As renewable energy transforms the energy landscape, efficient energy storage solutions are needed. Grid-connected facilities position themselves at the forefront, adapting to the evolving energy paradigm and contributing to a resilient, sustainable grid system.

Battery Storage

Battery storage systems are emerging as pivotal connectors, seamlessly linking green energy sources with the dynamic demands of electricity.

How it Works

A battery storage system serves a crucial role in capturing electricity produced from various sources, primarily intermittent renewables. This stored energy is strategically released back to the grid during high-demand or low-generation periods. This flexibility addresses the inherent peaks and troughs in renewable energy generation, adapting to climatic conditions. It is proposed that the system will use a form of Lithium-ion battery technology - commonly found in everyday devices like smartphones and computers.

Additional battery storage has a compelling case for enhancing both the energy system and local networks. A key player in achieving net-zero goals, battery storage offers clean and flexible capacity vital for a fully zero-carbon electricity system. National Grid anticipates that the UK needs over 50GW of battery storage by 2050, compared to the current 2.4GW. Beyond providing balancing services, battery storage significantly aids in managing the increasing volatility of renewables, storing excess energy for when it's needed most. It also offers locational benefits by supporting local grid management. In 2022, UK battery energy storage saved approximately 615,000 tonnes of CO2 emissions, equivalent to removing 370,000 cars from the road.
