Our current energy situation
Electricity currently the highest spend on NOPEX at 43% with diesel contributing to 31%Target is to reduce diesel cost on the KPLC sites and the 24/7 genset sites 82% of the sites on KPLC, 3% of 24/7 Genset, 4% on Hybrid power and 11% sites without gensets
Our Carbon footprint…
• In 2012, we calculated our carbon footprint for the first time to help
us understand our emission sources and how to reduce.
• Our total carbon footprint is 70,257 tCO2e
• Main sources of emissions– Fuel used in generators, vehicles,
refrigerant gases, electricity from the grid
• Uncertainty attached to reported figures – 14%

Performance curve for Mara Governors
Average generator run per day dropped from 24hrs/day hours to 7.5 hours. 93 such units now installed across the network . 61 units expected to be installed by 30th April 2013.
Free cooling boxes installation highlight
Performance curve Ewaso Ngiro
Installation of free cooling box commissioned on this site on 17th February, 2012.
The peak power for the site has reduced by 25%.
103 such units now installed across the network.
405 units targeted to be commissioned by 30th April, 2013.
Staggering the start up load with smart controller reduces genset size requirement by up to 50% with the resultant genset efficiency

Community Power Projects - Objectives
• Poor local community, cannot afford
cost of power.
• Request from the community.
•Request from donors engaged with the
community in other development projects.
• Rapid expansion of Mobile Money MPESA
services to the rural areas.
• Optimum network utilization and
improved Rate of Return (no sleeping cells)
for lack of subscriber activity.
