The Power Division has circulated a standing instruction for generation, transmission and distribution agencies and companies to ensure proper management of the national electricity grid.
Centring the blackout on November 1 last year, the circular was signed by Power Division Joint Secretary Md Mahbub-Ul-Alam. He said coordination among all entities is must for ensuring proper management and supply.
The circular describes 47 separate points for generation, transmission and distribution companies.
Nearly a month after the blackout, State Minister for Power Nasrul Hamid said lack of adjustment between production and supply had caused the blackout.
At present, 12 agencies, companies and independent power producers generate, transmit and distribute electricity under the Power Division.
Short term instructions for agencies and companies generating power include identification of technical fault and formation of troubleshooting teams.
Power stations have to assign groups who will work on six-hour shifts to ensure that frequency remains under control.
Mid and long-term instruction for power generating agencies and companies include ensuring at least one auxiliary unit at one power station in each region and completing maintenance between November 1 and February 15 every year.
Short-term instructions for transmission companies include ensuring presence of at least one official not below the rank of executive engineer at the National Load Despatch Centre (NLDC) to manage the emergency situations.
Other instructions for them are ensuring implementation of grid code at all grid sub-stations, distribution agencies and power plants to prevent grid failure; and identifying the reasons behind frequent tripping at the Bheramara High Voltage Direct Current sub-station and take measures accordingly.
