A hydroplant to power a rural hospital in Uganda.
Econnect, renewable energy specialists, have been working on a UK Government
DTI funded project to improve the efficiency and accessibility of micro
hydropower through intelligent load management for a charity hospital
in Kisiizi, South West Uganda. Situated 30km away from the Ugandan
National Grid, the hospital has been dependent on a stand-alone hydro scheme
for its electricity supply since it was built in 1958. Inevitably,
electricity demand has risen as the hospital has grown, resulting in the
potential for blackouts, which occur when demand exceeds supply.Benefits
Areas of the hospital have been prioritised so that they do not suffer
from blackouts. Non-essential loads are shed when demand is approaching
blackout levels to prevent power being lost from high priority areas, such
as operating theatres.
The load controllers have been fitted in staff residences to improve the
quality of life for the staff and to help to attract and to retain skilled
staff. When there is very low demand, such as during the night, the
excess supply is used to heat water. Previously, hot water to wash
with was considered a luxury.
The first visit to Kisiizi to install the monitoring system took
place in March 2002, with a second trip in August 2002 to install the load
management equipment. A third trip took place in November 2002 when
excellent feedback was obtained.
Safety Feature
The controllers have been fitted with an additional safety feature,
which allows the user to manually switch devices, such as irons and electric
cookers, back on when the power becomes available. This will prevent
any accidents arising, should the user leave the devices unattended, while
the power has been temporarily shed.
Sustainability
Local staff have been trained to install, commission and maintain the
equipment.
Feedback
Excellent feedback has been received:
-
"I no longer know where my candles and matches are!"
-
"Previously, operating in pitch darkness increased the hazards slightly
for the patient!"
-
"We can once again confidently say that we have better and more reliable
power at Kisiizi than at either Kampala or Kabale, It's also free - that
is a good tool for attracting staff."
