The carbon footprint of transformers during the life cycle, including raw materials, production and operation stages has been analysed.
- Transformer lifecycle
The following graph shows the carbon footprint contribution of 3 stages of the transformer lifecycle in proportion:
The figures are index values (raw materials assigned as 100) and are intended to show the relative magnitudes as an average.
The average load of the transformer during operation is taken as 50 %, and the lifetime is assumed as 40 years. For transformer producers, raw materials are defined as Scope 3 and usually no reported (Scope 3 reporting is voluntary).
The absolute values of the figures may show some variations depending on several assumptions made during the calculation, however, the proportions will not change.
This graph clearly shows that the dominant part of the carbon emissions takes place during the operation of the transformer. The consequences one may derive from this graph will be discussed in a later part of this article.
