If you’re a commercial or industrial customer in our Massachusetts service area, you’re likely getting your utility bill from several companies, but the most prominent of them is Eversource Energy. For example, what was once the National Grid (also known as Mass Electric & Nantucket Electric) is now an Eversource Energy entity. For this article, we’ll refer to customers as National Grid (NGRID).
Below, we explain your monthly NGRID utility bill, break down what you’re paying for, and highlight where you can save. For reference, we’ve spelled out some of the typical language you’ll find on your bill, like the difference between supply and transmission and how to read kilowatt-hours (kWh) on your bill.
Your NSTAR bill includes:
- A 10-digit account number
- A 4-letter name key (first 4 letters of your commercial name)
- Supply and delivery charges, electricity usage history and summaries, usage, and meter graphs
Supply Charges
When reading your NGRID bill, supply charges are on page 3 of your utility bill. With NGRID you have the option to select your energy supplier. If you opt for an energy service company (ESCO) besides NGRID, your Supply Services will list your new ESCO, including your electricity supply costs.
For NGRID customers, your supply charges reflect your electricity supply and gas supply. There is a merchant function charge listed for both charges. If you recall from our previous blog post, your merchant function is a charge for purchasing gas or electricity supply on your behalf. The “ESRM” on your bill stands for Electricity Supply Reconciliation Mechanism. This is on your utility bill each month when customers are with the utility for supply and there will be a charge or a credit.
Despite NGRID being an Eversource entity, in this service area, their bill is not reflective of Eversource billing. See a sample energy bill here.
Delivery Charges
Unlike supply charges, the delivery charges are predetermined and can change due to a variety of factors, including seasonality. Utilities have total control over the price of transmission due to the cost of delivering electricity to your business, but you can use your supply cost to achieve extra cost savings.
NGRID customers will find their delivery charges on page 2. This page shows your total usage and a breakdown of your delivery charges including electricity and gas. Under your electricity charges, you have your basic service charges—this doesn’t include your actual usage. It’s a fixed rate no matter how much electricity your business consumes. Your total usage reflects the kilowatt hours you used between your previous meter reading and current meter reading. At the bottom of the page, under your gas charges, you’ll notice how many “therms” you used during this period as well as the total quantity of gas you used (measured as Cubic Feet).
The amount of therms used during this billing cycle that are listed on this page tells NGRID how much heat was required at your business. The higher your therms are, the higher your utility bill will be. The “RDM” listed under your delivery charges stands for Revenue Decoupling Mechanism—it’s how NGRID makes previsions on the revenues of customers’ delivery services. When the target for delivery revenues is reached, the surplus amount will be refunded to the customer. If not, NGRID collects this money from its customers.
