CPS Energy calculating credits based on meter reading CPS Energy is now offering credits for customers who endured the cold and dark, but that credit was a lot lower than expected for most customers. Author: Niccole Caan (KENS 5) Published: 4:43 PM CDT April 16, 2021 Updated: 4:43 PM CDT April 16, 2021 SAN ANTONIO, Texas — You probably got a letter from CPS Energy showing your credit from not having power during the winter blast. It shows most of us are getting an $8.75 credit. That is the Electric Service Availability Charge. It is what you pay each month to have service and many of us did not have power for some period of time. Yet, CPS Energy said if you were without power for 48 hours or more during the five-day winter storm period, you would get another credit of $50 to $100. Yet, many of us are not seeing any extra money.
