Traction Bulk Supply Points are large capacity grid connections designed to support peak demand on the rail traction system. Because traction power is typically very peaky in nature this capacity is not optimally utilised. Installing battery storage facilities at traction BSPs and unlocking connection agreements to enable two-way dynamic flow could shift rail energy demand away from peak periods, unlocking capacity for other customers; support regional balancing of supply and demand; fulfil unmet demands for flexibility services in areas with network constraints; and increase the commercial scope for new traction-connected generation capacity, replacing curtailment with load shifting and export capability.

This project brings together two feasibility studies funded under the original GCRE Feasibility Study call. EneRail proposed the modelling of the GCRE power requirements to understand the potential of and Energy Management/Control System. OXTO energy proposed a fly-wheel Energy Storage (ES) technology to capture regen-braking energy from vehicles. The project proposes to combine these two approaches to demonstrate the possibility of a Energy Management/Control system for GCRE that enables the site to balance renewable power sources, regen-braking captured through the fly-wheel ES solution, and a grid connection to provide traction power for vehicles in operation at GCRE. This proposal plans to deliver a demonstrator, at an appropriate rail relevant scale, for an energy management/control system that brings together renewable sources, ES and grid connection for the first time for traction. The commercial potential of such a solution is significant and has significant benefits for the indutry and wider stakeholder groups.
