Summary
reduction This methodology applies to the project that aims for saving

measuresenergy by introducing energy efficient wire stranding machines
in Vietnam.

Calculationof

reference GHG emissions associated with electricity consumption ofemissions

reference wire stranding machines are calculated based on themonitored electricity consumption of project wire stranding
machines, electricity consumption ratio per production unit
(hereinafter referred to as “ECR”), and the CO2 emission factor
for consumed electricity.

Calculationofproject GHG emissions associated with electricity consumption ofemissions

project wire stranding machines are calculated based on themonitored electricity consumption of project wire stranding
machines and the CO2 emission factor for consumed electricity.

Monitoring parameters

Electricity consumption of project wire stranding machinesThe amount of fuel consumption and the amount ofelectricity generated by captive power, where applicable

F. Establishment and calculation of reference emissions
F.1. Establishment of reference emissions
Reference emissions are calculated with electricity consumption of project wire stranding
machines, electricity consumption ratio per production unit (ECR), and CO2 emission factor forelectricity consumed.
ECR is provided as a default value in this methodology and is conservatively set ex ante in thefollowing manner to ensure the net emission reductions.
1.

The wire stranding machine with higher energy efficiency currently available in theVietnamese market is determined as a reference wire stranding machine.

2.

Electricity consumption per production unit (EPU) of twisted wire by wire strandingmachine, which is expressed in [kWh/km] varies depending on the twisting speed.
Therefore, ECR is uniquely determined as the minimum ECR value in the range of the3
