Implementation/roll-out
Small scale roll-out started January 2015
200 Sub Stations will be fitted with an SSLD to control public lighting and tariff switching
15 municipalities in the Liander grid operator area will be participating
Goal is to allow municipalities to use the application, give feedback and to see if the services offered to municipalities are adequate
Large scale roll-out will start around 2016
The entire Liander grid operator area will use SSLD's to control all public lighting and tariff switching
About 25.000 Sub Stations (middenspanningsruimtes)
About 800.000 street lights will be switched by the SSLD's mounted in the 25.000 Sub Stations
FlexOVL web application (not open source available)
Municipalities are free to choose their own (web)application (using the web services of the Open Smart Grid Platform), or they could use the default web application developed by Alliander.
Functionality of the default web application as used by grid operator Liander (example)
Create switching schedules and assign those schedules to one or more SSLD's
Create groups of SSLD's in order to be able to assign schedules to many SSLD's at once
On demand switching of public lighting
Review current status of an SSLD in order to review public lighting and tariff switching states
Abilities to monitor power consumption of public lighting (available if the SSLD is fitted with an Electricity Meter)
Monthly report offering insight into switch moments and power consumption
