How this application benefits stakeholders?

  • A user-friendly interface, on the Geographical map of Andhra Pradesh, facilitates all the consumers / stakeholders in visualization of the power supply status at overall State level and at District/ Town/ Village level. The information disseminated through the Application will empower the consumer, thereby leading all the stakeholders to be more responsive and efficient, bringing more transparency.

What is the source of data??

  • The actual demand and energy drawls recorded at various EHT Sub-stations and consolidated at State Load Dispatch Centre.
  • The power supply status, interruptions recorded at various 33/11 KV Sub-stations
  • Scheduled outages and probable time of restoration of supply updated by the territorial DISCOM officers.

What does “Maximum Demand” indicates?

  • Maximum Demand indicates the maximum power drawn in MW by the respective unit (DISCOM/ District) in the entire day.

What does “Energy Drawls” indicates?

  • Energy drawls shows the energy drawn from the electricity grid by the respective unit (DISCOM/ District) in Million Units. For example,
    100MW for 24 Hrs = 2.4 MU (Million Units)

What is SAIDI?

  • System Average Interruption Duration Index (SAIDI) is commonly used as a reliability indicator by electric power utilities. SAIDI is the average outage duration for each customer served, and is calculated as:
  • SAIDI is measured in units of time, often minutes or hours. It is usually measured over the course of a year or month. AP Discoms are measuring in Minutes and on daily basis.

What is SAIFI?

  • System Average Interruption Frequency Index (SAIFI) is the average number of interruptions that a customer would experience, and is calculated as:
  • SAIFI is measured in units of interruptions per customer. It is usually measured over the course of a year or month. AP Discoms are calculating SAIFI on daily basis.

What is CAIDI?

  • Customer Average Interruption Duration Index (CAIDI) is a reliability index which is related to SAIFI and SAIDI. CAIDI is calculated as:
  • CAIDI gives the average outage duration that any given customer would experience. CAIDI can also be viewed as the average restoration time. CAIDI is measured in units of time, often minutes or hours. AP Discoms are measuring CAIDI in Minutes and on daily basis.

What are metered sales?

  • Metered sales indicate the no. of units metered by the respective unit (DISCOM/ District) whereas unmetered sales represent assessed consumption of the unmetered agricultural services.

What are T&D Losses?

  • Transmission & Distribution (T&D) Losses are nothing but the difference between energy supplied at the Input Points and Energy Billed to Consumers in percentage terms for a particular period:
    (Energy Input LESS Energy Billed to Consumers in kWh/ Energy Input in kWh)*100

What are AT&C Losses?

  • Aggregate Technical and Commercial Losses (AT & C Losses) are nothing but the sum total of technical loss, commercial losses and shortage due to non- realization of total billed amount:
    {(Total Energy Input LESS Energy Realized)/ Total Energy Input}*100.

In my State, as per the information available through this application there is no shortage of power. However, we don’t have power supply for hours together. What could be the reason for same?

  • Shortage means the difference between the requirement and the actuals available. When AP Discoms are meeting their requirement, the shortage is ‘zero’. Presently, Andhra Pradesh is supplying power to all consumers on 24x7 basis.
  • However due to network constraints and unforeseen faults in the network and equipment sometimes we could not able to extend supply even though there is sufficient power available.
  • However AP Discoms are striving hard to overcome these network constraints.

I have an urgent work tomorrow. Can I be assured of uninterrupted supply?

  • AP Discoms strive to provide uninterrupted and reliable power supply to all their customers. However sometimes supply may get interrupted, due to network constraints and unforeseen faults in the network and equipment.
