6 Transmission System <strong>Development</strong> <strong>Plan</strong><br />
of:<br />
Transmission System <strong>Development</strong> Projects in PDP <strong>2015</strong> during <strong>2015</strong> – <strong>2036</strong> consist<br />
6.1 Transmission System <strong>Development</strong> Projects to Cope with the Growing<br />
Electricity Demand<br />
6.1.1 Bulk <strong>Power</strong> Supply for the Greater Bangkok Area Project Phase 3<br />
(BSB3)<br />
The Bulk <strong>Power</strong> Supply for the Greater Bangkok Area Project Phase 3<br />
(BSB3) is the successive project of BSB2 and was approved by the Cabinet on October 15,<br />
2013. The project consists of many subprojects such as the voltage upgrade of the<br />
existing 500 kV transmission lines from 230 kV to 500 kV, the reconstruction of 230 kV<br />
transmission lines, the construction of 230 kV new substations and renovation of existing<br />
substations to cope with increasing demand, to solve the problem of shutting down for<br />
gas field maintenance in Myanmar and to support the long term distribution system<br />
expansion plan of the Metropolitan Electricity Authority (MEA). It is planned to be<br />
completed during 2016 - 2018.<br />
6.1.2 Bulk <strong>Power</strong> Supply for the Greater Bangkok Area Project (Future<br />
Phases)<br />
The next phases of Bulk <strong>Power</strong> Supply for the Greater Bangkok Project<br />
Area will be the successive project of BSB3 to cope with the increasing demand in the<br />
Greater Bangkok Area in the future. In addition, EGAT has planned to implement the<br />
underground cable or underground substation for serving increasing demand, avoiding the<br />
new Right – Of – Way (ROW) of transmission system and reducing public impact in the<br />
future. Nevertheless, these technologies will take long time for consideration and need to<br />
use technical experts. The future phases of Bulk <strong>Power</strong> Supply for the Greater Bangkok<br />
Area Project and its implementation period are as follows:<br />
Period<br />
Bulk <strong>Power</strong> Supply for the Greater Bangkok Area Project, Phase 4 2019 - 2025<br />
Bulk <strong>Power</strong> Supply for the Greater Bangkok Area Project, Phase 5 2026 - 2032<br />
Bulk <strong>Power</strong> Supply for the Greater Bangkok Area Project, Phase 6 2033 – 2039<br />
6.1.3 Transmission System Expansion Project No. 12 (TS.12)<br />
The project was approved by the National Council for Peace and Order<br />
(NCPO) on August 19, 2014. It aims to handle the increasing demand and support the<br />
power system security except Bangkok area and its vicinity. The TS.12 is the successive<br />
project of TS.11 and to support Provincial Electricity Authority (PEA)’s distribution<br />
