A paydown balance is an amount owed to SRP. A percentage of each purchase made while on SRP M-Power is applied to this balance until it is paid in full. If the total amount owed to SRP is: Less than $500, 35% of future purchases will go toward the paydown balance. Between $500 and $1,000, 50% of future purchases will go toward the paydown balance. Over $1,000, 70% of future purchases will go toward the paydown balance unless you receive our Economy Price Plan (EPP) monthly discount. For EPP customers, the paydown percentage will be capped at 50%. If you have a balance of over $500 that falls below $500 as you make payments, your paydown percentage will drop to 35%. If you would like to lower your paydown balance faster,  you can make payments by giving us a call. Lowering your balance can allow more of your purchases to go toward your meter.
