What it Does: Reviews and approves plans for the utilities to purchase energy. Establishes policies and utility cost recovery for energy purchases. Ensures that the utilities maintain a set amount of energy above what they estimate they will need to serve their customers (called a reserve margin), and implements a long-term energy planning process.
