Transmission lines play an important role in the successful and stable operation and distribution of power grids both for power evacuation from power plants and as a link from one Substation to another. The construction of new transmission lines as a form of meeting high electricity needs in the current era of Globalization has many obstacles, both in terms of rejection from residents, expensive licensing arrangements, and very expensive investment costs. Reconductoring is one of the methods of increasing transmission capacity at minimum cost with an adequate level of quality and reliability. Reconductoring is the best solution today to increase conductor conducting capacity with the least investment and get maximum economic efficiency. However, considering that reconductoring is an addition of transmission capacity using old or existing lines and also requires tower replacement, so an outage with a long duration is needed which is feared to have an impact on system reliability. Therefore, the use of emergency towers is believed to be a solution to shorten the blackout time. Emergency towers are used as tools in reconductor work and tower replacement. A study was conducted by calculating the Cost Budget Plan (RAB) and schedule analysis using the Microsoft Project Application to determine the comparison of the duration of time needed to complete reconductoring work and tower replacement between using an emergency tower and without an emergency tower. From the time schedule made, it will be known which work method uses a shorter duration of time so that it can save or speed up the blackout time. This study is expected to produce a shorter schedule of reconductoring and tower replacement work using temporary/emergency towers and with a smaller RAB compared to Total Operating Costs so as to shorten the duration of the outage time at an efficient cost.

“…Previously, such investment was required on a case specific critical components inventory. This led to a major chunk of financial reserves availability to handle such situations [18,19]. The interchangeable modular ERS structure could be easily transported to even difficult locations and can be reused in future exigencies.…”

In the past decades, various ideas have proposed for reconductoring of overhead lines to enhance power transmission capacity considering growing energy demand. Conventional method of reconductoring is use to take couple of weeks but availability of shutdown for a prolong period is a major constraint in line uprating. Emergency restoration structure (ERS) is effective to deliver such challenging task within hardly 4-5 hours line shutdown only. This quick restoration and easiness is mobility features are making ERS versatile for restoration even after any natural disasters. In this article, a case study of 132 kV restorations is described as a conceptual proof of concepts. Successful execution of this project resolved a 400 kV transmission line hindrance between Atur and Indira Puram since March 2017 and was likely to remain idle due to a 132 kV single circuit transmission line crossing its route.
