As winter approaches in New England, energy costs typically rise due to increased demand and limited natural gas supply, which is heavily relied upon for both electricity generation and heating. As a result of these ongoing challenges, the price of electricity purchased on behalf of customers is expected to increase starting January 1 to 12.64 cents per kWh, an approximately 13% change to the rate when compared to last winter’s rate of 11.19 cents. Customers are encouraged to take control of their energy supply costs by shopping for competitive rates at EnergizeCT.com.

With the weather turning colder across New England, customers will soon be using more energy to heat their homes and businesses, which leads to increased demand on the natural gas system. When the region experiences extreme cold snaps during the winter, that heightened demand can be even greater, which is why Eversource is taking proactive steps now to prepare. As part of its year-round efforts to manage and maintain the natural gas system, the energy company is conducting routine inspections of its infrastructure and readying equipment ahead of the winter heating season, which is critical to providing safe, reliable service to customers when the temperatures drop.

Bill help financial assistance energy efficiency

As Connecticut embraces the start of fall and cooler weather, it’s a reminder that heating season is just around the corner. Regardless of how you heat your home, now is the time to prepare for increased energy usage during the winter months. Electric supply rates typically increase in January due to greater demand of natural gas, which the region relies on to generate electricity. Customers who use natural gas to heat their homes also see a significant increase in usage when the temperatures drop, driving their monthly bills higher. With these seasonal changes in mind, Eversource encourages customers to shop for a lower electric supply rate offered by third-party suppliers on EnergizeCT.com and take advantage of the various options available to help manage energy bills, including flexible payment plans, energy efficiency programs, and financial assistance. The company is hosting multiple webinars and in-person events in the coming weeks where customer care representatives will be on hand to go over these resources and connect customers with the options best for them.

In recognition of National Safe Digging Day as 8/11 approaches on the calendar, Eversource is reminding customers to always call 8-1-1 before starting any project that requires digging, whether it’s as basic as planting a shrub or tree, or as complex as installing a deck or pool. Statistics show excavation work causes damage to underground utility lines every six minutes in the U.S., and a simple call to 8-1-1 in advance of digging to mark those underground lines can not only avoid electric or natural gas service interruptions, but also possible injury or even death. According to the US Department of Transportation, if someone calls 8-1-1 before they dig, they have a 99 percent chance of avoiding an outage or a catastrophe.

Energy supply third-party suppliers electric rates

As winter approaches, Eversource is reminding customers they can take control of their energy costs by shopping for a third-party supplier before an expected supply rate increase that typically occurs at the beginning of each year. Roughly half of New England’s electricity is produced using natural gas, and seasonal demand for the fuel drives up the price power generators charge. Under state laws related to deregulated energy markets, Eversource is prohibited from generating electricity and is required to purchase power on behalf of customers who’re not enrolled with an alternate supplier. Those costs are passed on with no mark up or profit to the company. In anticipation of the higher cost of electricity, customers are encouraged to compare rates being offered by third-party suppliers on EnergizeCT.com. Those who’ve never shopped before can find help navigating the process to shop, sign up, and save by going to Eversource.com/supplier.
