The peak electricity demand for the entire state of Sikkim during winters is recorded at 80 MW per day, but Sikkim is currently receiving barely 50 MW.
Power Grid Corporation India Ltd has been shutting down the Siliguri-Melli 132 KV transmission line and the Kurseong-Rangit 132 KV transmission line on a continuous basis since 27 January; a procedure which is scheduled to continue till 02 February 2013. This shutdown, it is informed, is being done for emergency stringing of transmission line conductors at a new tower location (No. 194) situated near Kurseong in West Bengal.
With the two transmission lines down, the Eastern Regional Load Dispatch [ERLD], Kolkata, which is the main grid that supplies power to Sikkim, has restricted Sikkim’s net withdrawal to 50 MW [against a peak demand of 80 MW] to avoid tripping of power in grid disturbance. This has necessitated load-shedding during the peak demand hours from 5:30 PM to 8:30 PM in Sikkim
