Bus2Grid seeks to deliver commercially operated fleets which comprise significant numbers of similar vehicles with large batteries at single sites, avoiding challenges of fleet dispersion, diversity of ownership and lack of standardised technical solutions.
The focus is towards:
- Software and technology validation at test centre
- V2G capability for 28 e-buses in commercial operation at a London depot
- A comprehensive aggregation service for V2G assets
- Trials of grid services and dispatch arrangements
- Business Models and technical case studies to address V2G market entry barriers
How are we achieving this?
e-Bus Depot Capability to provide Grid Support
- Typical fully electrified bus depots could provide around 2-10 MW firm availability for overnight grid services and could participate in National Grid FFR and DNO services
- UK Power Networks launched last year its Flexibility Roadmap as a first step to release DNO benefits and creating a local flexibility market. It has also launched flexibility tenders through Piclo platform
- Fixed vehicle schedules offer very predictable periods of demand and connected storage
Electric bus depots as a source of energy and power can provide 300kWh per bus and 40 kW export capacity per charging point for around 120 buses per depot (London average). With V2G technology the potential could provide huge increases: 36MWh per depot and 4.8MW per depot.
