What do customers think about Constellation?
That depends on who you ask. There will always be someone who feels wronged by a company, no matter how good they actually are. The average Constellation customer review is 3.6 / 5 stars. Keep in mind, consumers will go out of their way to complain far more often than they will to give praise.
Why is my electricity rate higher than when I signed up?
The rate you see when you sign up is the average rate at that exact amount of usage in one billing cycle. Some companies try to game the system by applying bill credits between certain usage thresholds. It works great if you are within the margins, but as soon as you leave that band you no longer get that bill credit and your rate per kWh can double. The PUC only requires that companies disclose their average rates at 500, 1000, and 2000 kWhs. Companies can get around this by giving you a $50 bill credit if you use between 1000 and 2000 kWhs per billing cycle. The only way to really know what you're getting into is to read your EFL. A 10¢ rate at all usage amounts may end up being cheaper than that 8¢ rate at 1,000 kWh!
