ENERGY + ENVIROFICIENCY

to efficiently deliver sustainable, economic, and secure electricity [12].

Upon comparing information from the generation and transmission

sector with that of the distribution sector, we find there is enough

power being generated and the transmission network is fairly reliable

but the bottleneck is in the distribution network. We therefore propose

the following smart grid applications for Uganda:

o Automatic Metering Infrastructure (AMI) and Demand Side

Management (DSM):

Consumers are suffering from the effects

of high tariffs, unstable and inadequate power. With AMI and

DSM, the price of power would be varied basing on demand such

that power during peak hours electricity is more expensive than

at off peak hours. Consumers would control their consumption

during peak hours thus reduce transformer overload. Consumers

would also be empowered to control their consumption so as

avoid the high power tariff. Lastly if smart appliances and sockets

are used in the consumer premises, direct load control would be

possible [13]

o Distribution automation:

The distribution network suffers a lot

of faults which sometimes take long to sectionalise. Distribution

automation would ease fault management and possibly control

vandalism

o Distributed generation:

There is a need to have distributed

generation in order to relieve the load on the transformers in the

distribution network

o Energy storage:

The country relies 70 % on hydro power, which

varies with water levels. It would be good if in the rain season,

electricity would be stored

Conclusion

The future for any electrical grid is in converting to a smarter grid.

However before this can happen it is important for countries to

clearly articulate the specifications of the smart grid that address their

problems and thus propose smart solutions to them. This paper has

explored the status of Uganda’s electrical power grid and identified

critical problem areas that will require custom designed smart solu-

tions. The next stage of this research will be to study documented

cases from elsewhere in the world and identify similar aspects and

the emerging technology options that could be adapted to address

the Ugandan power grid issues.
