Transport UK London Bus electrifies first London bus route
London bus company Transport UK London Bus (TULB) has introduced a fleet of electric double-decker buses to one of their busiest routes in London, route 63.
Designed to support the 29-strong EV fleet, the operator has developed its Walworth depot in London to incorporate fully electric routes with power infrastructure, maintenance and charging facilities.
They partnered with Siemens and Siemens Financial Services to acquire a total solution, from initial consultancy, through to depot redesign and retrofit, charging infrastructure implementation and optimisation, software management systems, and ongoing maintenance and optimisation.
The Siemens end-to-end depot electrification solution comprises of:
- Consultancy and depot simulation to identify opportunities to install charging solutions in the depot, whilst minimising space used
- Installation of 34 150kW Industrial Rapid Chargers to enable sufficient charging levels were achieved over the short periods of time that buses returned to depot. This was further supported by depot management software Depotfinity, which automatically optimises charging sessions within a limited headroom, reducing energy usage, maintenance costs and power levels
- A SIVACON S8 LV board, LV busbar and harmonic filtering to ensure the relative power needs of the depot and charging stations are met
- A bespoke 14-year service level agreement and warranty to ensure both current and future needs at the site are met, and any charging issues are resolved quickly.
In order to make this solution financially manageable for TULB, Siemens Financial Services put in place a tailored, ‘smart’ financing package – embracing consultancy, technology, software, grid connection and ongoing maintenance. Structured across 14 years in line with the company’s contract with Transport for London, the financing arrangement eliminates the need for capital to be tied up in the solution. The financing solution was also flexed to be sensitive to TULB cash-flow requirements, with a low-start profile ramping up over time, aligning payments with benefits for the bus operator.
John Eardley, managing director, TULB, said:
“With the strength of financial support through Siemens Financial Services, Transport UK London Bus was able to build its electric fleet, including depot, charging infrastructure and grid connection, while minimising capital expenditure.”
