        Energy is a basic necessity of life. It is otherwise known as power & one of the prime movers of any development economy. Adequate & reliable availability of power is indispensable for sustained growth of economy. The state of Orissa has carried out reforms in power sector to provide consumers cheap, reliable & assured supply of power. In order to achieve this objective, the Orissa Electricity Reforms Act came into effect from  Ist April, 1996. With the enactment of Orissa Electricity Reforms Act,  the erstwhile State Electricity Board was restructured & the functions of OSEB were entrusted to GRID Corporation of Orissa & Orissa Hydro Power Corporation . The distribution function of GRIDCO was privatized in the year 1999 & was entrusted to 4 private distribution companies. Central Electricity Supply Company of Orissa (CESCO) Limited looks after distribution of electricity in Angul district.

This electrical division encompasses 3 subdivisions- Angul Chhendipada and Boinda.Talcher Electrical division, Chainpal  having headquarters at Chainpal has jurisdiction over Talcher town, Talcher Kaniha, Pallahara  blocks and part of Banarpal block. This division consists of 3 subdivisions- Chainpal,Talcher and Pallahara.  

There are 54,835 consumers in Angul district. Details of different category of consumers are presented below.

 Power Supply

Angul district gets power supply through GRIDCO transmission system at Chainpal, Angul, Rairakhol EHV substations having a transformation capacity of 132.50 MVA interconnected with 107 km of 132 KV line. GRIDCO   receives power from O.P.G.C, OHPC, NTPC, and CPP of NALCO & distributes it to different distribution companies.

Sub transmission and distribution system

There are 18 number of 33/11 KV substations with 88 MVA capacity and 1473 distribution transformers  . There are 23 number of 33KV feeder lines    of 549 km length ,  58 number of 11 KV feeder lines of 2265.7 km length and LT lines of 1784 km length.

 Transmission & Commercial losses

        The  transmission & commercial losses  are of the order of about 45%,  estimated commercial loss is 30% and estimated technical loss is 15%.

Transformer failure rate

        The average transformer failure rate of 33/11 K.V. transformers is 4%. The distribution transformer failure rate is 18%.

       The existing level of performance may be enhanced as follows:

       Challenges

          The main challenges for enhancement of performances are :

1. Reduction of losses.

2. Improvement in billing and revenue collection efficiency.

3. Improvement in quality and reliability of power supply.

      To achieve these objectives  CESCO has undertaken the following measures: 

1. Deploying ex-army personnel as security men for regular   checking & removal  of unauthorized connections  .

2. Separate M.R.T. squad for detection of tampering of meter, by-pass to reduce the theft of energy through unfair means.

3. For 100% metering, defective meters are being replaced by new   transparent and tamper-proof meters.

4. For speedy billing and revenue realization spot  billing method is adopted and bills issued to the consumers  on the spot with the help of a hand-held machine

5. Improvement in collection and reliability in power supply in rural areas, village committees have been formed in 51    villages. 

6. New distribution transformers have been  installed  in the different areas of the district for reliability in power supply and voltage .

          The existing level of performance may be increased to match the required targeted level of performance.
