How to get your electric data from National Grid
Interval data is your electric meter’s reading every 15 minutes: a log of how much power your building used, and when. National Grid releases it once you sign one form. We request it, and you send us 12 bills.
What we need
For each National Grid account in Massachusetts.
- Interval data
- We request it from National Grid once you sign the form.
- Monthly bills
- The last 12 bills, saved as one PDF each.
- Before you start
- A recent bill, so we can check the rate and fill in the account number.
Four steps, one of them ours
National Grid opens interval data through its Energy Profiler Online once the account holder signs, so we handle the request for you.
Check your rate or meter
National Grid’s Energy Profiler Online (EPO) is for accounts with interval data meters. In our experience that means accounts on rate G-3 and accounts with enhanced metering. Look for the rate code, such as G-3, on your bill.
G-3 is National Grid’s time-of-use rate for larger accounts: it’s mandatory once a 12-month average monthly demand reaches 200 kW for three consecutive months. On another rate? Send us a bill and we’ll check.
Sign the authorization we send you
We send you National Grid’s third-party interval data request form for the account, usually by DocuSign. The account holder signs it, authorizing National Grid to share the account’s interval data with us.
We pay the EPO enrollment fee when we arrange your data request.
We request the data
We email the signed form and your account number to National Grid’s interval data team. National Grid opens EPO access to the account’s interval data for a set service period, and we tell you when it’s in.
Send your last 12 bills
Log in to My Business Account (or your online profile) and open your billing history, which holds up to 24 months of previous bills. Download the last 12 as PDFs, one per bill.

Send it to us
Email the bills to us, or reply to your EQORE contact with them attached. Questions about the form go to the same address.
- The signed interval data request (we send it to you)
- The last 12 bill PDFs, for each account
If you’d rather get it yourself
Two National Grid options you can use on your own. Send us what you download along with the bills.
- Green Button Connect
- Sign in to your account, go to “Manage my data” and download your historical data as CSV or XML. National Grid doesn’t say what interval the business files use, so we’ll tell you if it’s enough.
- Energy Profiler Online
- Fill in the Massachusetts customer enrollment form and email it to National Grid’s interval data team. Under its Optional Interval Data Service tariff, the first two-week access request per account each calendar year is free.
What “interval data” means, in plain English
Interval data is your electric meter’s reading every 15 minutes: a log of how much power your building used, and when.
Your utility already records it. Getting a copy takes your utility login, a signed form or a read-only sharing link, depending on the utility.
Why we ask for it as well as your bills
On most commercial rates, the demand charge is set by your single highest 15-minute average in the billing period. A bill shows that one number. The interval data shows every 15 minutes of the year: when the peaks happen, how long they last and how often they come back.
That is what sizes a battery. A short spike needs power for a few minutes; a two-hour plateau needs energy. Bills alone can't tell the two apart, so we ask for both.

National Grid data questions
What is interval data, and why do you need it?
Interval data is your electric meter’s reading every 15 minutes: a log of how much power your building used, and when. Your bill shows only the monthly totals and the single highest 15 minutes, which sets your demand charge. The interval data shows when those peaks happen and how long they last, and that is what decides how big a battery you need and what it can save.
Can I just send PDFs of 12 months of bills instead?
Bills are a good start, and we can give you a rough first read from them alone: your rate, your monthly usage and the peak behind each demand charge. What bills can’t show is when that peak happened, how long it lasted or how often the building came close. That is what sizes a battery and sets the savings, so for a proposal we need the interval data too.
What is Energy Profiler Online?
EPO is National Grid’s online tool that gives access to a facility’s retail interval load data, for accounts with interval data meters. Access is opened per account for a set period once National Grid has a signed request.
Which National Grid accounts can get interval data?
National Grid offers EPO to accounts with interval data meters. In our experience that covers G-3 and enhanced-metering accounts. If you’re on another rate, send us a bill and we’ll check what your meter records.
Will the interval data match my bill exactly?
Not always. National Grid says EPO data isn’t billing quality, so it may not match the monthly bill, and there can be gaps when the meter can’t communicate. That’s one reason we ask for the bills too.
I have several meters or accounts. Does that matter?
Only in that we need the data for each one. Tell us every account number so we can request them together, and send the last 12 bills for each account.
Does signing the form give you exclusive rights, or lock me in?
We send National Grid’s own third-party interval data request. Signing it authorizes National Grid to share the account’s interval data with us until you or we tell National Grid otherwise, so you can withdraw it by notifying National Grid. The form also says a customer signature is valid for one year after signing. It doesn’t mention exclusivity, an energy supply contract or any change to your service or rate. If you request EPO access yourself with the customer form instead, you choose a term (two weeks, a year, or renewing automatically each year) and agree to pay the charge shown on the form. Both forms are public; read them before you sign.

I don’t have a National Grid login. How do I get one?
Register for My Business Account, National Grid’s free portal for business customers. You need your account number and access to the phone number on the account. You only need it for the bills; the interval data comes through the form.
Who do I ask if I get stuck?
Email info@eqore.com or call (857) 524-2670. We can tell you where your request stands.
