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

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

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

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
