Chapter 1. Background and Necessity of Project1.1.Introduction (Background)In India, national energy consumption has continued to grow due to recent annual economicgrowth, becoming the 4th largest in the world at the end of 2012. Supply has not kept up with thedemand growth, with a 3.6% shortage in energy (supply of 1,028,955GWh for demand of1,067,085GWh), and a 4.7% shortage in capacity (generation capacity of 141,160MW for peakdemand of 148,166MW) in FY2014-15. To counter these problems, in energy sector reforms afterthe New Electricity Act was introduced in the 12th Five year Plan (2012-2017), new powerdevelopments will be focused exclusively on supercritical technology after the 13th Five yearPlan (2018-2023) and transmission and distribution network reinforcement and ruralelectrification will also be critical domestic issues.Located in the central part of India, the State of Madhya Pradesh has the 2nd largest surface area(308,144km2) and the 6th largest population (73 million) in India. The state constitutes part of theDelhi-Mumbai Industrial Corridor (DMIC), which is a mega-infrastructure project initiated byIndia and Japan, and has plans for industrial development in the future, including the developmentof a Special Economic Zone near Indore airport, a distribution center near Dewas and theindustrial area of Pithampur. To achieve sustainable development in the state of Madhya Pradeshthe electricity demand will continue to increase. In the state’s power demand-supply balance inFY2014-15, there was a 0.5% shortage in energy, with a supply of 53,445GWh for a demand of53,737GWh. To cope with the energy deficit, the government of Madhya Pradesh has signedcontracts with Independent Power Producers (IPPs) to develop further power plants, and thegeneration capacity of the state will increase in the future. Since the increased power should flownot only into the urban areas, but also into the rural areas, transmission line system strengtheningis essential for the entire state. To strengthen the power system, the Japan InternationalCooperation Agency (JICA) provided a loan, with a total project cost of 22,213 million yen andthe loan amount of 18,475 million yen, for “the Madhya Pradesh Transmission SystemModernisation Project” (JICA Phase I Project) in 2011. The JICA Phase I Project has beensuccessfully implemented to improve the power system in Madhya Pradesh. Meanwhile, to copewith the increasing power demand in the future, the Madhya Pradesh Power TransmissionCompany Limited (MPPTCL) prepared a Detailed Project Report (DPR) for “TransmissionSystem Strengthening Works in Madhya Pradesh” (Project) for expected financial cooperationfrom the Japanese government, concerning transmission system development with newtechnologies like Low Loss type ACSR (LL-ACSR) conductor, High Temperature Low Sag(HTLS) conductor, and Gas Insulated Switchgear (GIS), to stabilize and reduce losses in the1

power transmission system. Some further refinement of the Project is necessary.Table 1-1 Demand Forecast in 18th Electricity Power SurveyState/UtsDelhiHaryanaHimachal PradeshJammu & KashmirPunjabRajasthanUttar PradeshUttarakhandChandigarhNorthern RegionGoaGujaratChhattisgarhMadhya PradeshMaharashtraD. & N.

1.2.Purpose of the ProjectThe purpose of the Project is to strengthen MPPTCL’s transmission lines and substations to copewith the increasing demand for electricity in the state of Madhya Pradesh. It is conducive to thecapacity increase and the stability of the power transmission system.1.3.Outline of the StudyThe following table shows the outline of the Study.Table 1-2 Summary of the Study1.4.ObjectiveBased on the introduction of new technologies for loss reduction andan efficient system in Madhya Pradesh, the purpose of the study is toprovide technical assistance for improvement of the Project, includinga review of the DPR with new technologies and environmental effects.Scope1.2.3.4.5.PeriodJuly 2015 to October 2015 (two visits to India)Study AreaMadhya Pradesh state, IndiaCounterpartMadhya Pradesh Power Transmission Company Limited (MPPTCL)Review and update of MPPTCL’s power system development planReview and update of the DPRStudy on introduction of new technologiesAssistance with environmental and social considerationsReview of implementation schemeOutline of the Power Sector in Madhya PradeshThe power sector in Madhya Pradesh was originally operated by the vertically-integrated MadhyaPradesh State Electricity Board (MPSEB) as per other states in India. To improve its power supplyefficiency and to meet the growing power demand, the Madhya Pradesh VidyutSudhar Adhiniyam,2000, was enacted in 2000 and enforced in 2001, along almost the same timeline as the otherstates in India. This unbundled the power utilities and separated generation from powertransmission and distribution in order to encourage market mechanisms in the power sector. Underthe act, Madhya Pradesh Electricity Regulatory Commission (MPERC) was established andstarted operation from 2001 as a regulatory authority to monitor and control power utilities andto promote competitiveness in the power sector. At the same time, Madhya Pradesh PowerGenerating Company Limited (MPPGCL) as a generation company, MPPTCL as a transmissioncompany, and three area-wise distribution companies were established in 2002 (see Figure 1-1)MPPTCL owns and operates the transmission system of voltage levels over 132kV, while3
