As an Exelon company, Constellation Energy is part of one of the biggest — and historically most polluting — corporations in North America. Given Exelon’s vast production energy, ranking on the PERI Toxic 100 list is perhaps not that surprising. The good news is that Exelon is upfront about its room for eco-friendly improvement and make it easy for Constellation customers to go green, too.
Usually, fixed-rate renewable-energy plans are among the most expensive options. But in our research, we found Constellation’s green plan rates were comparable to its non-green versions. For example, out of two otherwise identical fixed-rate, 12-month plans from Constellation — “12 Month Fixed Rate 100% Green” and “12 Month Fixed Rate” — it’s the renewable version that currently costs less.

A lot of these financial structures ultimately boil down to being a form of government guarantee, which means that they can’t be scaled up to “solve” countries’ power problems because the governments cannot carry all the liabilities. Countries try to introduce the private sector into power generation precisely to reduce such guarantees, which then end up returning through the back door in the form of government support.


Aided by the fact that the Evergreen State doesn’t collect a corporate income tax, cheap power has attracted industries that tend to consume biblical amounts of electricity, from aircraft production to software development to aluminum refining. Major companies in these spaces that are either headquartered or maintain a significant presence in the state include Microsoft , Amazon.com , Expedia .com and Boeing.

Still, we like that if you choose to re-up with FirstEnergy again at the end of your initial term, you won’t have to worry whether you’re enrolling at an expensive time of year. First, since it offers just two options, constant for years, its prices are set with the long haul in mind. Second, since the electricity grid in Pennsylvania is more taxed during winter than any other season (space heating accounts for 50 percent of household electricity consumption in PA; air conditioning just three percent), signing up in summer means prices won’t be temporarily inflated.


In deregulated markets such as Texas and Maryland, the state government may require the incumbent utility energy provider to allow for unlimited competition within the marketplace, where the consumer is free to choose any electricity provider. Electricity provider switching is only practical if a customer is either buying from a utility or is at the end of a fixed-price contract with a provider.[citation needed]
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.
In this free market competing electricity retailers buy electricity wholesale from private power generators to sell at retail to around 85% of Texas residents. The partnership between generators and retailers is governed by the Electric Reliability Council of Texas, or ERCOT, which attempts to balance the power grid’s electricity supply and demand by purchasing small amounts of electricity at 15-minute intervals throughout the day.
Variable-rate supply plans, as the name suggests, have a rate that varies based on the market price of electricity. Seasonal and market fluctuations can affect supply rates. While variable-rate supply plans can allow you to take advantage of market-price lows, there is the possibility of paying for high supply rates when demand is at its peak. These plans offer great flexibility.

The Texas Senate Bill 7, passed in 2002, gave 5.6 million Texans the power to choose a retail electric provider (REP) to supply electricity to their home or business. This bill facilitated a competitive energy marketplace that 85 percent of Texans can capitalize on today. Energy choice is available to residents in Houston, Dallas/Fort Worth as well as other cities in Texas.
Switching electricity supplier could shave pounds off your bills. But it’s not always about how much hard cash you could save. You might be fed up with poor customer service, you might want greater visibility of your usage through an app or you might want to choose your supplier based on their green credentials, or whether they supply a smart meter.
