BHUBANESWAR: Worried over the recurring incidence of electrocution, the State Government has decided to replace single and double poles with elephant-friendly electricity structures in districts where the jumbos are most vulnerable. To avoid the electrocution, narrow based lattice structures (NBLS) will be established in Dhenkanal, Angul, Keonjhar and Mayurbhanj by replacing the single and double poles in all 11 KV and 33 KV lines in future.
