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


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)

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
