for supply options
Total Savings = 28 to 30
MW
Customer Perspective
(Free CFL)
Energy savings per CFL per
day = 192 watt-hours
Energy savings per CFL
over lifetime= 280 kWh
Bill Savings per month =
US$0.70
(Paid CFL)
Payback period ~ 3 months
(at today’s tariff)
Bill Savings/mo/CFL =
$0.70

Installation of Capacitors
![Page 14: Short-Term Approaches to Address Electricity Shortages...Presentation to MEMD The World Bank April 28, 2006 The World Bank Page 2 Short-Term Strategies to Address the Electricity Shortage](https://reader035.vdocuments.us/reader035/viewer/2022071610/61495d1b080bfa6260148ff3/html5/thumbnails/14.jpg)

Capacitors
Power factor compensation through installation of
capacitors
Targeted for industrial, institutional and large
commercial customers
UMEME study of 94 large customers
Observed power factor ranges from 0.6 to 0.95
Of total of 86 MW load, 76% are below 0.9 PF
Target of power factor (international utility best
practice) = 0.95+
Estimated savings of about 10 to 20 MW just for
these 94 customers
![Page 15: Short-Term Approaches to Address Electricity Shortages...Presentation to MEMD The World Bank April 28, 2006 The World Bank Page 2 Short-Term Strategies to Address the Electricity Shortage](https://reader035.vdocuments.us/reader035/viewer/2022071610/61495d1b080bfa6260148ff3/html5/thumbnails/15.jpg)
Page 15The World BankShort-Term Strategies to Address the
Electricity Shortage in Uganda
Program Options
Install capacitor banks at industrial, institutional and large commercial customers
Additional network analysis of required – install electronic energy meters with half hourly load profiles to measure kW, kVAr (lag), kVAr (lead), kVA, and power factor or do a quick energy audit
UMEME has already initiated the assessment work on some feeders and large industrial customers
In the future, introduce two-part tariffs (for both kWh energy and kVAr demand)

Program Options
Provide a subsidy to manufacturers/suppliers or
customers to help reduce the system costs
Extend the existing PSF Credit Support Facility
to SWH systems
Develop a low-cost financing program to
facilitate customer purchase using a “pay from
savings” concept (similar to PSF program for PV)
Undertake an intensive awareness and
promotion campaign
Require SWH systems to be installed on all new
homes over a certain size.
