I am an Economy 7 customer, what does this mean for me?

Economy 7 customers will see a decrease of 4.1% to the day rate and 14.1% to the night rate. Based on a weighted average unit price. This means the price paid per day will decrease by approximately £64*per year from 1 April 2024.   
*£64 per year decrease is calculated using the Power NI unit price decrease of 6.3%, with a weighted average of the Power NI E7 standard unit rate and an average usage of 3,200 units (kWh) per year.
