12th Five year Plan
Key Issues and Concerns from STU’s
Prospective
Tariff based bidding in Intrastate Transmission
Network Development – Cost constraints to pay RoW cost and forest clearance
Smart Grid Solution: Though we talk, Not many companies are ready with full end
to end solution with modular features.
Land for Substations – Ban on use of Gaucher Land
Aged Assets – We cannot ignore it, so Renovation and modernization is essential
Skilled manpower both Executive & Non-executive
Renewable Energy Integration – As high as 30% of total installed capacity
Lack of Inter-State line – Renewable Energy flow not taken care
Key Issues and Concerns
10th & 11th Five Year Network Addition & 12th Five year Plan
•392 no of sub-stations, which are more than last 14 years cumulative figures prior to 2007
•120% increase from 10th FYP to 11th FYP
• Major focus on 66 KV Substation (375 nos of 66 KV S/S constructed in 11th FYP)
•First 400 KV Sub-station in South Gujarat and Kutch Region – 400 KV Kosamba & Varsana
10th & 11th Five Year Achievement & 12th Five year Plan
•9786 CKM of tr. line, which are more than last 13 years cumulative figures prior to 2007
•123% increase from 10th FYP to 11th FYP
• Major focus on 400 KV & 66 KV Transmission lines
•First 400 KV link between Kutch to Saurashtra (400 KV Mundra-Varsana-Hadala)

R&M Planning – Key Factors
Why need of R&M ?
• 1600 Kms of coastal line with wind pressure/ creek areas.
• Chemically polluted industrial zone.
• Challenge of uninterrupted & quality power supply on 24 X 7 basis
due to frequent equipment failure and tripping of lines.
• Inadequate capacity and obsolete design.

• The complexity of Gujarat Grid increased with integration of IPP, UMPP, CPP, Non-
conventional Energy sources like Wind, Solar, Bio-mass Generation and increase in
Transmission Infrastructure in the State.
• Reduce Manual Intervention so less Chances of Error.
• To address all complexities of Energy Accounting and scheduling methodology
• Future changes can be implemented smoothly, safely and timely.
Proposed Architecture of PMUs and WAMS:
• It is one of the Prime Project towards the journey of Smart Grid Technology.
• WAMS facilitate the system operator to know Dynamic behavior of the system
• PMU data is used to design many analytics software like Dynamic state estimator,
Oscillation stability, Voltage stability which are intelligent tools to system operator to run
system safe and reliable manner in real time.
• It can be concluded that if present SCADA system is X-ray status of the system and
WAMS is the MRI status of the system.
• It will change the mind set of system operator from conservative steady state to real time
Dynamic status.
