About Automatic Generation Control (AGC):

• AGC has been launched by the Union Ministry of Power and New and Renewable energy.
• Its aim is to ensure power balancing in real-time to keep supply and demand in sync for power generated through renewable energy.
• It is being operated by Power System Operation Corporation (POSOCO) through the National Load Despatch Centre (NLDC).
• Through AGC, NLDC can send signals to more than 50 power plants in the country every 4 seconds to maintain the frequency and reliability of the Indian Power System.
• This will ensure more efficient and automatic frequency control for handling variable and intermittent renewable generation.
