An increasing demand for Energy
●Energy must be available●Reduced outages
●Reduced outage duration
●Energy must be of high quality●Guarantee of voltage level
●Harmonic management
●Energy must be cost effective● Investment cost optimization
●Reduced operational cost●Real-time cost mastering
Schneider Electric – Distribution Automation – 2008 4
Electric utilities need to Improve their Efficiency
●Reduce number and duration of outages●Cables, lines and switchgears improvement:Use Schneider Electric MV equipment!●More looped-network, shorter feeders●Staff competencies improvement● Fault location and network reconfiguration●Distribution automation
● Improve quality of distributed energy ●Voltage level control●Harmonic filtering
●Optimize investment costs● Load flow monitoring● Transformer monitoring●SCADA feeding with reliable and accurate data

Electricity outages: an economic stake
●Financial consequences of defective power supply● For end users
●Loss of revenues (non productive time)●Deterioration of production or even process itself
● For electricity suppliers●Loss of revenues●Maintenance costs●Damage to distribution hardware●Customer satisfaction●Regulator penalties

Cost of Non-Distributed Energy (NDE)
● yearly incidents rate● average power consumption● outage time● kWh price
Cost of resulting consumer perturbationsS = W x c x dt
S: distributor benefitsW: Non-distributed energy dt : outage time reduction thanks to networks remote controlc: 20 to 50 times selling price: according to country wealth

●SAIDI (System Average Interruption Duration Index) can vary from a few minutes to several hours,
●SAIFI (System Average Interruption Frequency Index) can vary from 0,1 to10 and more, depending on :● population density (rural or urban area)
● proportion between underground and overhead distribution
●maximum accepted costs for non distributed energy
Excellent Average Poor
Urban area < 10 mn 30 mn >2 hrs
Rural area < 30 mn 2 hrs >10 hrs
Permanent Interruptions (>1 mn)
SAIDI/SAIFI variations

SCADA installation and implementation,a long and expensive process?
●Definition of needs and specification writing by experts - 12 months●Which SCADA-DMS functions?
●Which transmission networks?●Which units rehabilitation works?
●More than 12-months tendering process●18-months implementation ●Long training, configuration before system
handling●Long capital mobilization and delayed return
on investment (>36 months)

SCADA-DMS Vs Easergy L500
● Apprehensions regarding a SCADA project● Long● Complex● Resources consuming● Capital mobilization● Delayed ROI
● Focus investment on network instrumentation thanks to:● Preconfigured SCADA for Easergy devices● Basic SCADA with just enough functions to manage Easergy devices data, not
more
