We understand your concern about the electricity charges on your bill. You are seeing these charges because your NEM credits have run out. This is common in the winter months as solar arrays generate less electricity (due to shorter days and less sunshine). When the credits of your previous excess solar generation are used up, MCE helps to meet your demand for electricity. When your panels are able to produce power that exceeds your usage, you will no longer see MCE charges and will start to see the credits on your bill again.
