GTTPL

Transmission Assets co-exist with nature

Currently, Goa’s base electricity demand is 650 MW. The power demand is primarily catered through the Western Grid via the 400kV Kolhapur-Mapusa line, and from the south, through a single 220kV line.

In 2015, the Ministry of Power, envisaged the Goa Tamnar Transmission Project Limited (GTTPL) to create an additional source of power for Goa. Subsequently, the decision to provide a new 400 kV substation in South Goa along with its interconnections with the Inter State Transmission System was discussed and approved in the various meetings convened by the Standing Committee on Power System Planning and Standing committees of Western Region and Southern Region in 2016.

The GTTPL project, once operational, will play a vital role in meeting Goa’s increasing power requirements and providing long-term energy security to the state. It will provide residents and industries in Goa with a highly reliable power feed by opening access to both Western and Southern grids, thereby reducing the dependence of this region on expensive and polluting diesel based power.

Project Details

GTTPL comprises of 5 elements that are related but functionally independent. These together constitute the scheme for “Additional 400 kV Feed to Goa and Additional System for Power Evacuation from generation Projects Pooled at Raigarh (Tamnar) Pool”.

400/220kV Substation at Village Sangod in Goa

The total capacity of the 400/220 KV substation is 1000 MVA, comprising of 2 transformers of 500 MVA each, with provision for future capacity addition of additional 500 MVA.

This substation is being built on a private land over an area of 1.72 lacs sqm. The land for the substation was acquired in 2018.
It will be connected to the Western grid through the 400kV Xeldem – Mapusa line, and the Southern Grid through the 400kV Xeldem-Narendra LILO line. The presence of these two transmission lines will result in enhanced power reliability in the region.

The substation has the potential to cater to the growing power requirement of Goa for the next 15 plus years.

400kV D/c Sangod – Narendra Transmission Line In Line Out (LILO) Line (spans across Goa and Karnataka)

The total length of 400kV Sangod-Narendra LILO transmission line is 93.67 km. This line connects the upcoming Sangod substation in Goa to the Dharwad district in Karnataka.

In Goa, out of the total line length, 2.51 km passes through the Bhagwan Mahaveer Wildlife Sanctuary and 7.99 km through forest area. The line does not pass through the Mollem National Park.

In Karnataka, only 6.61 km of the line passes through the Dandeli Wildlife Sanctuary and 31.88km through forest areas.

765kV D/c Dharamjaigarh – Tamnar Transmission Line (Chhattisgarh)

The total line length of Dharamjaigarh (Chhattisgarh) – Tamnar transmission line is 68.72 km. The construction of this line has commenced in July.

400kV D/c Sangod – Mapusa Transmission Line (Goa)

The 400 kV Sangod-Mapusa line spans across Goa covering a total line length of 54.96 km. It will connect Goa to the Western Grid. The line connects Mapusa in North Goa with the substation at Sangod village. Out of 54.96 km, only 15.089 km of the line passes through the forest area.

Best possible efforts have been made to minimize passage through forest area in the final route selection. These efforts have increased the length of transmission line by approximately 4 km.

220kV Sangod – Xeldem transmission line (Goa)

The total line length of 220kV Sangod – Xeldem transmission line is 20.481 km. This line will connect the upcoming Sangod substation with the existing Goa Electricity Department (GED) substation and will enable GED to further distribute power across South Goa. In order to ensure minimum impact on forest, three possible alternate routes were considered, and the proposed route was selected basis minimum forest area impacted.
Only 8.069 km of the line passes through forest patches.

Project Impact

Enhance Power

Enhance Goa’s power capacity, reliability and security by enabling more than 1,200 MW of power evacuation from both the Western and Southern grids.

Uninterrupted Power Supply

Ensure uninterrupted power supply to Goa even during the peak tourist season.

Emergency Backup

Yet generating electricity from sunlight alone is a powerful resource with applications and benefits throughout the world.

Strengthen Transmission Capacity

Enhanced power transmission capacity, quality and reliability in the state will further boost the industrial and commercial activities, especially the tourism industry, while minimizing the use of DG sets.

One Nation One Grid

Improve Goa’s standing in the “One Nation One Grid” scheme which was conceptualized to improve India’s power connectivity infrastructure and ensure affordable power supply to the states.

Capacity Reserve

Where does the energy we use come from? It’s absolutely vital to every single thing we do every day, but for most people, it is utterly invisible.
