Making National Power Grid Vigorous
Save money on utilities or increase the value of your home by installing solar panels as a great option.
Strengthen National Power Grid

Transmission lines are an integral part of power distribution. Like national highways, transmission lines are considered to be “shared assets.” It would be uneconomical and technically infeasible to build dedicated transmission systems for individual states. Acknowledging this, since 31 December 2013, the country has operated a single synchronously operated national grid, rather than the regional grids which were in existence previously.

The UKTL project will help strengthen the National Grid which in turn will help in optimal utilization of scarce natural resources by transfer of power from resource centric regions like Karnataka to load centric regions like Kerala. It will also facilitate power trading across regions, thus, establishing a vibrant electricity market. This will further support “One Nation, One Grid, One Price,” facilitating exchange of operational surpluses amongst the regions.

Critical Energy Lifeline for Southern Region

With accelerated growth of industries and infrastructure development, the southern region is witnessing an exponential increase in power demand. However, S1 (Andhra Pradesh, Karnataka and Telangana) and S2 (Tamil Nadu and Kerala) is congested almost most of the time of the year. This sometimes lead to no power flow between S1 and S2. The UKTL project will help in easing of S1-S2 transmission corridor constraints, thereby facilitating power flow between S1 and S2. Once commissioned, this project will improve evacuation to the extent of more than 1000 MW power which will be critical in meeting the energy requirements of the industries and citizens of the region.

Enhance Power Transmission Network
The energy infrastructure will be enhanced by the UKTL project's commitment to boosting Karnataka's transfer speed.
Augment Power Transmission Infrastructure

Southern Regional Load Dispatch Centre (SRLDC) has highlighted the transmission constraints in Karnataka in their letter dated 30th March 2022. In the letter, it states that every year during the peak demand season, the transmission system in Karnataka experiences severe overloading on 400/220 kV ICTs and 220 kV transmission lines, breaching the security of grid. Further, the 400/220 kV ICTs at most of the stations are operated without N-1 criteria. Any tripping among these ICTs would lead to cascade tripping which may endanger the national grid. The UKTL project will help augment the transmission in Karnataka thereby strengthening the national grid.

Udupi power Plant which is supplying about 1100 MW to Karnataka State under long term PPA will be benefited by this line, in case of any tripping of existing lines, which can lead to blackouts in Mangalore and Bangalore region.

In future LILO arrangement from this line can provide more reliable power to Mangalore region which currently faces frequent load shedding.Being part of ISTS grid, reverse flow of power from Kalpakkam Nuclear Power project, post commissioning of additional capacity will help meet future power requirement for Karnataka.
