Innovative investments with good ROI
• Overview Ticket to Kyoto investment work package
• Investment status and (expected) performance• T2K WP2 challenges 2013/2014
Overview investment work package T2K
gOEnergy efficiency Energy recovery
Energy production
Goal: Succesful cases of energy reducing investments in
public transport infrastructures
WP2 63% of the project budget
Ticket to Kyoto investments
Investment focus: mainly energy efficiency of stations
Energy efficiency
STIB moBiel RATP RET
TfGM
Energy efficient lighting
Energy efficient metro staff area
Eco station
Energy efficient point heating
T2K Investment status and (expected) performance
June 2013: Movement sensors installed and operational in all 16 RET underground stations .
Enabling RET to safely turn off lights in these stations at night
– Approx. 428,720 kWh / year saved
– ROI 3 to 4 years

T2K Investment status and (expected) performance
Energy recovery 2013: Building and testing different
installations
Expected performance– Depends on network and system
Performance indication:moBiel: saving 866,000 kWh
RET: saving approx. 300,000 kWh/year/installation; ROI 5 years (with Interreg)
• moBiel: testing two inverters and one storage system
• STIB: System comparison until summer 2013
• RET: installing 2 reversible substations
Ticket to Kyoto investments
Investment focus: producing and reusing energy locally
Energy production

Cogeneration
Green station
Heat recovery - Adiabatic cooling
Heat pump metro stations
Cooling system for technical rooms
Wind power
Water power
T2K Investment status and (expected) performance
Energy production TfGM Horwich Parkway wind turbine operational, Sept. 2012
– Saving approx. 27,000 kWh/ year – Lower Feed In Tariffs negative influence on ROI
TfGM Rochdale hydroelectric turbine installed in 2011– Expected approx. 150,000 kWh / year – ROI 3 years with Feed in Tariff
STIB Delta depot Cogeneration installation operational, 27 Nov. 2012 – Combined generation of heat and electricity - 30% more efficient– 168 tons CO2 reduced/yr– ROI >4 years with Feed in Tariff
