How many hours prior should a Heavy Load Voltage Schedule Warning be sent before implementation?

A Heavy Load Voltage Schedule Warning should be sent with adequate time for all stakeholders to prepare for potential adjustments related to voltage schedules during periods of heavy load. Sending the warning 4 hours in advance allows enough time for the electric grid operators and utilities to implement necessary changes or measures to effectively manage the voltage levels during peak demand conditions. This proactive communication is essential for maintaining grid reliability and ensuring a coordinated response among various entities involved in grid management. By choosing to send the warning 4 hours ahead of implementation, it balances the need for timely information with the requirement for sufficient preparation time, ensuring that all parties can react appropriately to the forthcoming challenges.
