Battery & Energy Storage (BESS) Cables

Battery & Energy Storage (BESS) Cables

Cleveland Cable Company is the UK's largest supplier of battery & energy storage (BESS) cables. Energy storage systems are crucial to advancing electricity storage solutions, offering promising innovations for the future of clean energy and power resilience. Battery Energy Storage Solutions are reshaping how electricity is generated, stored, and distributed across the UK and beyond. They play a central role in modernising grid infrastructure and supporting the transition to low-carbon energy systems and decentralised power networks. With global deployment accelerating at an estimated compound annual growth rate of over 20%, energy storage is now a strategic priority for utilities, developers, and private operators seeking secure and flexible power capacity to support renewable energy growth.

BESS is currently being installed at utility, commercial, industrial, and residential scales, significantly increasing electricity storage capacity. These systems enable efficient storage of surplus renewable energy rather than waste, particularly electricity generated by solar installations. They also help stabilise supply during periods of fluctuating demand. At Cleveland Cable Company, we support this shift by supplying high-performance cable solutions designed for long-term reliability. Our expertise aligns with the demands of renewable and low-carbon power projects across the UK. Energy storage works hand in hand with solar, wind, hydro, and biomass installations. It also complements emerging technologies such as green hydrogen, nuclear generation, and carbon capture and storage. Together, these systems reduce reliance on fossil fuels, strengthen clean energy security, and deliver consistent power output from renewable sources.

Utility-Scale Battery Energy Storage Infrastructure

Utility-scale battery storage is increasingly used to balance the electricity grid. These installations help defer peak generation requirements and ease congestion across electricity transmission and distribution networks. Responsive battery systems maintain grid frequency during high-demand periods and store electricity generated during off-peak times for later use. As technology advances, utility-scale BESS projects are becoming more cost-effective and are now essential assets within national energy strategies.

Medium-voltage and low-voltage cable performance is critical in these energy storage environments. Cables must withstand electrical load, environmental exposure, and long operational lifespans. Cleveland Cable Company supplies solutions designed for these demanding conditions, supporting both private and public electricity grid connections.

Commercial and Industrial Energy Storage Applications

The same principles apply across commercial and industrial energy storage projects. Businesses are increasingly investing in on-site electricity storage to manage the value of solar energy.

Energy security and resilience are key drivers for adoption. These systems enhance operational flexibility by providing alternative power sources, reducing reliance on peak-time grid supply, and supporting corporate carbon reduction targets.

Battery technologies used in these systems offer scalable solutions for businesses, enhancing the efficiency and capacity of available energy storage technologies.

BESS Cables We Supply

Long-Term Reliability and Asset Protection

  • BESS projects typically operate for 20 to 30 years, making long-term reliability essential. Cable replacement can result in significant disruption and cost.
  • Long-term performance is particularly critical where cables are buried or cross privately owned land.
  • Our focus on quality and compliance helps mitigate these risks by supplying cables built for durability and longevity.

Construction Products Regulation (CPR) Compliance

Within Europe, the Construction Products Regulation applies where cables enter buildings, requiring the use of high-quality materials to ensure safety and durability.

Cleveland Cable Company offers a comprehensive range of CPR-rated cables, including:

  • Low Smoke Zero Halogen (LSZH) options
  • Declarations of Performance available on request
  • Documentation retained for the mandatory ten-year period
  • Cca- and B2ca-rated LSZH cables to suit regional Euroclass requirements
