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.
This company has more plan variety than any other we looked at, though most of them seem more flashy than functional. And some seem weirdly niche — like "Connect to Comfort," a 24-month plan that comes with a Hive Hub and a Hive Active Thermostat, smart home devices that allow you to control your heat and A/C via app. Like many of Direct Energy’s plans, how good of a deal it is depends on how closely its offers align with your established habits.
