by balancing Supply of Electric Power against Demand of Electric Power. Management
of Supply side involves scheduling own generation, drawl of power from common
pool and central sector generation stations as well as banking arrangement with
other states & purchase of power through traders. On the other hand Management
of demand side involves scheduling of electric power supply to various categories
of consumers through restrictions on the timings for supply, Peak Load restrictions
on industry as well as load shedding activity. State of the art EMS/ SCADA system
is a tool available with this office for online monitoring of the power system
in Punjab as well as whole of the Northern Region of India.
Besides this, whole of power data for the state of Punjab is being compiled
and maintained. Industries which are continuous process in nature are declared
after due process involved. Exemptions from Peak Load restrictions for industry
are also processed by this Directorate.

modern communication media etc.) has been established in SLDC building at
220KV Grid Sub-Station, Ablowal, Patiala for collection of on-line data from
Punjab’s Generating stations, 220KV & 132 KV Sub-Stations. SCADA
scheme had been implemented in PSEB in two phases namely Interim SCADA Scheme
and Unified SCADA scheme.
- SCADA scheme for the 1st time in PSEB was introduced as Interim SCADA scheme
in the year 1999 covering most important Generating stations and 220KV &
132KV sub-stations. The scheme was integrated with Unified SCADA scheme in
the year 2002.
