I just did the simplest thing. I transferred service and set the dates to end at my house and when to begin at the new house. There are myriads of plans due to different electric companies and different terms. Some are short, some are long. Some are 100% green energy, some as little as 6% green energy. Several years ago, there was quite a large gulf in price between the green/non-green plans. Not anymore. The cheaper plans lock in a rate for a set period of time. To break contract, you pay $20 per month whatever is remaining on the contract. More expensive plans are month to month. Centerpoint Energy is the name of our main public utility company. They supply the power. A whole bunch of subsidiary electric companies administer the plans. Like I previously stated, quite a variety to choose from.
