Government of Bangladesh emphasized top priority to acceLerate the pace of electrification program throughout the countrr'. It is also a consritutional obligation to provide electric power in the rural areas. Bangladesh Rural Electrification Board has been established as a vital institution to help in improving the qualir_v ol lile of the rural multitudes and accomplish 'ast continuous advancement to $eir socio economic conditions through suppl) of stable and reliable electric power to the rural areas ofthe counh} as \lell as ro lirlfill fhe constitutional dght oflhe people to have electlicity. Based on the result of a comprehensive feasibility study in 19?6 BREB stands on the Afea Coverage Rural Electrification (ACRE) concept for ser,,ing electdcitJ, in a co-operative model. Govemment of Bangladesh's vision on the Polver sector is "to provide access to affordable and rcriabre electricity to all b) the year 2021". GOB'S 7th tlve-year plan emphasizes on the importance of elechicity for generatirg emplovment oppomrnities. Access to af'fordable and reliable electdcity is a key requirement tbr both econonic development and po!erf)- reduction. Imprcved electricity coverage, panicularh in rural areas. shall \rheal on to achieve the 7,r,five,r,ear plan. [n support ofGovernment,s vision, Bangladesh Rural lllectrification Board has been functioning with a firm aim to enhance electrification program all over the countrlside based on the concept of Area Coverage Rural Elecn-ilicatim (ACRE). Ihe ACRII concepr leads to the establishmenr ol co-operative called pally Bid:urSamit-v(PBS)todelirerelectricser\icestorheirmemberconsumers.Sinceinception,gonosof

PBSs ha\e been de\eloped all o!er the counrry under dillerenr projecrs ftom ACRI phase_I to ACRE Phase-V After establishing rhe PBSs, rhe disrribution svstem ofrhose pBSs were gradually expanded and iniensified underthe differcnt Intensification and Expansion projects.

At present BREB distriburioD network consists of,1,82,810 km lines (HT and LT), connecting 26.5 million consumers through irs 80 nos ot'PBSs. The major aim ofBREB is to ensure consumer services up to the mark of high satisfaction level through supply of .eliable and uninterrupted electicity at an affordable price. There is no other way but to convet BREB into a worid class renolvned modeln organization rvhich is one of the most challenging issues for the organization. BREB desires to creare Underground Disrributlon System facilitv firstly in Savar Upazila (part) in Dhaka District & Kaliakoir Upazila in Cazipur Djstricr under Dhaka pBS-t as a model like another modern city in the \\,orld

As per this project $ould help BREB to adopt a financial incentive plan based on weighted average ofinputs like generation, trarsmission. distribution, collection ofaccents receivable. project implemenfation ard training as labor management relations. Not oDly would this save people fiom extreme frustration and the depression of being unemployed, it would give people a new life, rer hope and nerv mode of enjoylent. Everyone $,ould become an active and productive citizen_ Ifl the process, it iould create a ne$, econom) avoiding wastage ofhuman creativitv and saving people from state dependencv.

Page 1 A BREB is the ieading electrical ener8v user in Bangladesh. Abour 50 % electricity is used by BREB consumers lately with increasing demand Government ofBangladesh is comrnitted for homogenous developnlent in each and everv part ofthe country reducing regional disparity. So, rumi consumers $ ill lead to sharc a lion portion of generating electricio, where BREB would play the role ofprime electriciO_' user b_v expanding distribution network to all the remote parts ofthe country.

BREB now inrends io hire an international consulting firm fbr Feasibilit) Study, preparation of Derailed Drawing, Design and Eslimate of Underground Electric Disrribution Network in Savar Upazila (Pad) in Dhaka Districr & Kaliakoir Upazila in Gazipur Disr ct under Dhaka pBS-1.
