Sunstone works in partnership with Telent to deliver remote power for platform technologies. 

As part of their commitment to sustainability and environmental stewardship, Telent has been pioneering a suite of green solutions designed to benefit the environment, customers, and supply chain partners. Central to this initiative is Telent's Green Solutions team, which aims to reduce the company's carbon footprint and enhance sustainability practices across its operations.


Telent's Environment and Sustainability Vision is to become a leading partner in the journey toward net-zero emissions while delivering exceptional service and solutions that support its customers' climate action goals. In collaboration with supply chain partners, Telent is focused on positively impacting communities affected by its operations. Over the coming months, Telent will showcase its progress toward net-zero through a series of detailed case studies.

Renewable Power for Remote Railway Locations
Telent, in collaboration with Sunstone Systems, has developed a cost-effective renewable power supply solution for remote locations along the Scottish Far North Line, where extending power cables would cost upwards of £500,000. This innovative hybrid solution significantly reduces environmental impact and operating costs while ensuring maximum reliability.

Hybrid Renewable Power Approach

The renewable power system developed by Telent and Sunstone Systems can supply up to 80% of the installation’s power needs through solar energy. This system is complemented by a battery storage facility and a hydrotreated vegetable oil (HVO) turbine generator from Bladon, which operates with only 10% of the emissions produced by traditional diesel generators. This solution not only meets current power needs but also lays the groundwork for broader applications in more localised and smaller-scale installations, supporting the broader transition away from fossil fuels.

Importance of Railway Stations

Railway stations are vital for connecting people, communities, and businesses, serving as transportation hubs that link remote areas with urban centres. Telent maintains critical telecommunications systems that ensure stations remain operational and trains run smoothly, providing integrated solutions across much of the UK's rail infrastructure.

Commitment to Net-Zero Emissions

Telent has pledged to achieve net-zero greenhouse gas emissions by 2050, aligned with the Science Based Targets initiative (SBTi). This commitment encompasses emissions throughout the entire value chain, from raw material extraction to customer use of products and services. Telent has set a near-term target to reduce all emissions by 50% by 2030.

Delivering Off-Grid Power

The Scottish Far North Line, known for its remote and inaccessible stations, presents unique challenges for power supply. These "request stop" stations, accessible only by rail and miles from the nearest road, are essential links for local communities. Despite their remoteness and lack of mains services, these stations remain critical. 

Telent leverages trailblazing clean technologies to help their customers decarbonise their operations.

Sustainable and Clean Technologies

Telent devised a more sustainable solution, currently tested at Inverness, in partnership with Sunstone Systems. This renewable hybrid approach includes:

  • Solar Array: Providing primary power for at least 80% of the year.

  • Battery System: Storing power for nighttime and low sunlight periods.

  • Back-up Biofuel Generator: Utilising hydrotreated vegetable oil (HVO).


Benefits of the Hybrid Solution

This sustainable solution offers numerous advantages for railway infrastructure, particularly in remote locations:

  • Reduced costs and CO2e emissions.

  • Zero onsite CO2e and noise emissions when operating on solar/battery compared to diesel generators.

  • Biofuel back-up generator produces 99% less CO2e than diesel equivalents.

  • Fuel deliveries reduced from six per year for diesel to one for HVO, minimising travel emissions.


By embracing these innovative and sustainable technologies, Telent and Sunstone Systems are not only addressing immediate power needs but also paving the way for a greener, more sustainable future for railway infrastructure.
