Having a reliable and uninterruptible power supply is key for the functioning of the rail infrastructure across the UK. Power to the railway cannot simply ‘go down’. This can be quite a challenge with such a long and narrow infrastructure (20,000 miles of track and 2500 stations!) to get supply to, but why is rail power supply so important?
Power distribution systems on trains, no matter their purpose, must be safe and reliable, which means complying with a host of standards, EN 50155 prominent among them. EN 50155 is a European standard that covers electronic equipment used on rolling stock for railway applications, including power supplies.
Railway applications always involve people, and performance and reliability are key enablers of both safety and quality. Power supplies, unless otherwise declared and documented according to the standard, must have a useful life of 20 years.
Some of those standards that especially apply to power supply design include: EN 45545-1: This standard concerns fire safety and specifies materials, construction, and testing required to mitigate fire hazards in railway applications. EN 50121-3-2: This standard addresses electromagnetic emissions and immunity for railway applications.
The global industrial and commercial energy storage market is experiencing explosive growth, with demand increasing by over 250% in the past two years. Containerized energy storage solutions now account for approximately 45% of all new commercial and industrial storage deployments worldwide. North America leads with 42% market share, driven by corporate sustainability initiatives and tax incentives that reduce total project costs by 18-28%. Europe follows closely with 35% market share, where standardized industrial storage designs have cut installation timelines by 65% compared to traditional built-in-place systems. Asia-Pacific represents the fastest-growing region at 50% CAGR, with manufacturing scale reducing system prices by 20% annually. Emerging markets in Africa and Latin America are adopting industrial storage solutions for peak shaving and backup power, with typical payback periods of 2-4 years. Major commercial projects now deploy clusters of 15+ systems creating storage networks with 80+MWh capacity at costs below $270/kWh for large-scale industrial applications.
Technological advancements are dramatically improving industrial energy storage performance while reducing costs. Next-generation battery management systems maintain optimal operating conditions with 45% less energy consumption, extending battery lifespan to 20+ years. Standardized plug-and-play designs have reduced installation costs from $85/kWh to $40/kWh since 2023. Smart integration features now allow multiple industrial systems to operate as coordinated energy networks, increasing cost savings by 30% through peak shaving and demand charge management. Safety innovations including multi-stage fire suppression and thermal runaway prevention systems have reduced insurance premiums by 35% for industrial storage projects. New modular designs enable capacity expansion through simple system additions at just $200/kWh for incremental capacity. These innovations have improved ROI significantly, with commercial and industrial projects typically achieving payback in 3-5 years depending on local electricity rates and incentive programs. Recent pricing trends show standard industrial systems (1-2MWh) starting at $330,000 and large-scale systems (3-6MWh) from $600,000, with volume discounts available for enterprise orders.
