KH Engineering Services Limited has confirmed it has completed its first major photovoltaic solar panel deployment on the rail network, just outside of London on behalf of train operator Southeastern.
The photovoltaic system is a power system that will supply solar power using photovoltaics (the production of electric currents at the junction of two substances exposed to light) which delivers electricity and carbon savings.
In explaining the rationale behind the project, Darren Bates, KHES Managing Director, emphasises that: “Renewable energy has an important role to play, and KHES joins Southeastern in encouraging other train companies to follow this lead and deliver more renewable energy capacity to help decarbonise the rail network.”
The project involved the addition of solar PV arrays at four stations;
- Grove Park, South London
- Gillingham, Kent
- Ramsgate, Kent
- West Marina, East Sussex
In total, just under 3,000 solar panels, were installed. The largest array at Ramsgate LMD (330kWp) is expected to generate at least 300 MWh of clean electricity each year.
Darren Bates commented: “The project was not without its challenges, but through effective collaboration we are proud to have delivered a first for the rail industry. Solar PV was assessed to be the most operationally suitable renewable energy technology, and one that incurs minimal post-installation intervention. The project required both senior management and staff to meticulously coordinate at all levels to ensure the PV arrays were installed efficiently and safely. Ultimately, solar power is good for the planet and the railway, and it also makes good business sense.”
Southeastern Head of Facilities, Peter Stapleton, added: “We always want to do more to reduce our carbon footprint and by enhancing the supply to our train maintenance depots we've been able to do just that. Since KHES finished the installation, we've been able to run some depots entirely off-grid from the PV arrays, thus reducing our demand. What's more, we were able to commission KHES to undertake this work without having any impact on the operational depots, benefitting passengers by ensuring that trains were able to enter and exit the depot at all times and our maintenance teams were able to go about their work.”

Substations that powers the live conductor rails which carries 750v DC could also do with solar panels to keep electricity running for the trains who use 750v DC 3rd Rail. Same with substations that powers the 25kv AC OHLE that solar panels could be installed to keep the overhead wires energised.
