How can Provider Power Mass offer me competitive rates?

Massachusetts deregulated its energy market in the late 1990’s, allowing companies like Provider Power Mass to buy power in the wholesale electricity market. Each year, the Mass Department of Public Utilities (DPU) holds a bid to determine who will provide the Basic Service supply rate in the Nat Grid, Eversource, WMECO and Unitil territories. Provider Power Mass offers alternatives to the Basic Service through our competitive rates for the power supply portion of your electricity bill.

How long before I see Provider Power Mass on by utility bill?

After completing your enrollment with Provider Power Mass, service commencement may vary depending on your utility’s enrollment requirements and your specific meter reading schedule. The good news is because you pay for your power after it has been used, you will be experiencing our competitive rate even before you see “Provider Power Mass” on your bill.

What changes can I expect to see on my bill?

There are two charges on your electric bill. One is for “Electricity Delivery” and the other is for “Electricity Supply”. These two charges make up the total due on your bill. Your utility is responsible for the Delivery charges on your bill and covers the cost of maintaining lines and meters, responding to outages and overseeing your account. The Supply charges are the cost of acquiring the actual electricity flowing into your home. “Provider Power Mass” will show up in place of “Basic Service” on the supply section of your bill.
