Dear K’ Khamloon,
Refer to your consulted about depreciation rate for Hydropower Project.
We did not have template for calculate them however we can guideline you about useful life and depreciation rate which rely on IFRS as below:
Useful life is
- the period over which as asset is expected to be available for use by an entity or
- the number of production or similar units expected to be obtained from the asset by an entity.
Depreciation is
the systematic allocation of the depreciable amount of an asset over its useful life.
Depreciable amount is the cost of an asset, or other amount substituted for cost, less its residual value.
Each part of an item of property, plant and equipment with a cost that is significant in relation to the total cost of the item shall be depreciated separately.
The depreciation charge for each period shall be recognised in profit or loss unless it is included in the carrying amount of another asset.
The depreciation method used shall reflect the pattern in which the asset’s future economic benefits are expected to be consumed by the entity.
So we thought you should consult about useful life and depreciation rate with you management such as how many year asset is expected to be available for use.
However with my work experience of the past I found that other company often calculate depreciation rate by rely on PPA agreement.
Finally, we prefer you consult within your company first purpose to the depreciation method used shall reflect the pattern in which the asset’s future economic benefits are expected to be consumed by the entity.
** Additional you can see in IFRS no. 16 which we already attached to you may be useful ka.
