Know that Green Mountain’s cheapest advertised plans are all variable rate plans. “Pollution Free,” “Pollution Free Try 3,” or “SolarSPARC 10 Try 3” all advertise a great initial rate — a full cent below Pennsylvania’s 8.49 cent “price to compare” — but its variable rates means the company can raise them at any time. The two “Try 3” plans just lock in the low introductory rate for three months instead of one. The flipside of fixed rate: Should prices fall, you’ll be locked into a contract with a constant, elevated rate for two more months.

Statement regarding savings: How your price compares. This is usually a generic statement that you may or may not be getting a better price than you would from the utility company, also known as the Electric Distribution Company, or EDC. Your local EDC sets a “price to compare” and any competitors’ plan may be lower or higher by several cents a kWh.
You’ll also see a flat rate and a price per kWh rate for TDU or TDSP (which stand for Transmission and Distribution Utility or Transportation Distribution Service Provider). These are costs that your utility charges for delivering electricity and maintaining power lines. The costs are unique to your local utility and have nothing to do with your electricity provider.
