Regarding access to electrical power, there are three typical configurations
(based on operator inputs): locations with an equipment room and access to
the electricity grid, locations with outdoor installation and grid access, and
outdoor locations without grid access (making use of power generators only). In
the latter case, all assets related to power generation have been put in the
“short life” category applying a 4 year asset life to the cost annualization.
The following table shows the results of the weighted average cost categories
for electricity access at a tower location in Rwanda, based on these operator
inputs. OPEX figures include the additional electricity and fuel usage to serve a
second operator.

Applying annualization factors leads to the following fully-allocated service
costs for electricity access. The monthly costs for tower sharing are derived by
dividing these annual costs by 12 and again by 2, assuming sharing between two
operators.
