Constellation is one of the largest integrated energy suppliers in the US, providing electricity and natural gas to over 2.5 residential and commercial clients, including two-thirds of Fortune 100 companies. The company promotes renewable power, and offers energy management products and services for both homes and businesses. From energy procurement to energy efficiency and distributed energy solutions — the company helps its customers strategically buy, manage and use their energy.

All Power Kiosk Direct supply rates are fixed for residential and small business customers, meaning you pay a fixed cost for energy over the time period you see listed for each plan. (Large commercial account? Depending on your business needs and market conditions, we can negotiate variable terms directly with suppliers.) No "act now" promotional rates. No airline mile gimmicks. And, importantly, your rate doesn't spike due to changes in the wholesale market.
There are several reasons that some energy suppliers end up being cheaper than others. The largest energy companies, also known as the Big Six, often do not need to offer rates that are as competitive as smaller companies. This is because they are more recognisable names and therefore can always rely on a steady base of customers. You can avoid this and save money by switching to a cheaper provider.

To do so, we used five of the state’s largest electricity companies to explore six things you'll have to evaluate when you're comparing plans and providers: We’ll walk you through customer satisfaction scores, running the numbers on rates, and calculating the impact of different fees, discounts, and contract types. We'll weigh in on extra perks, like points, and green energy too.

Knowing how much electricity you use each month is important to finding the cheapest electricity plan. For Houstonians, usage is typically the lowest in the winter and highest in the summer. Your specific usage levels can be determined by simply looking back at previous electric bills and finding the kWh used. To avoid electric bill surprises during the peak summer months, you’ll need to accurately know your peak electricity usage which typically occurs in August.

Twenty-nine states have deregulated electricity, natural gas or both. That allows you to shop for the supply portion of your bill from alternative providers who may offer rates lower than the default supplier – usually a utility. Delivery services and billing will remain the responsibility of the local utility as they own the power lines and wires that keep the lights on.
