Outline of GHG Mitigation Activity

This project introduces fast-chargeable lithium-ion batteries to base transceiver stations (BTS) owned by Grameenphone.
 Blackouts occur frequently in Bangladesh due to the gap between demand and supply, especially in poor-grid areas. Thus diesel generators and lead-acid batteries are used together for providing stable power to the BTS.
 This project achieves GHG emission reduction by replacing existing lead-acid batteries with lithium-ion batteries, which significantly reduces runtime of the diesel generators at each BTS in unstable-grid areas.

Expected GHG Emission Reductions

2,082 tCO2/year(10.41 tCO2 /year × 200unit )
Reference CO2 emissions: 22.55 tCO2/year/unit
Power consumption at BTS (19 MWh/year/unit)
CO2 emission factor (1.1872 tCO2/MWh)
Project CO2 emissions: 12.14 tCO2/year/unit
 Power consumption at BTS (19 MWh/year/unit)
CO2 emission factor (0.6392 tCO2/MWh)
