Understanding your Eversource Energy data breach notification letter
If a Eversource Energy letter arrived in your mailbox, here is what it means, why you received it, and the free steps you can take right now.
Why you received this letter
Eversource Energy is a major utility company that provides electricity, natural gas, and water services to millions of customers. As a utility provider, the company maintains sensitive records including customer names, service addresses, and billing information, which often includes Social Security numbers and financial account details used for payment processing. In 2026, Eversource Energy officially reported a data breach to the Maine Attorney General, confirming that unauthorized parties may have accessed personal information stored within their systems. If you received a formal data breach notification letter from the company, it indicates that your personal data was potentially compromised during this incident. We recommend reviewing the letter carefully to understand the specific scope of the exposure and the identity monitoring services being offered.
What to do after the letter
Confirm the notice is genuine
A legitimate Eversource Energy notice references the specific incident reported to the Maine Attorney General and describes which categories of your information were involved. Compare the letter against the public filing before acting on any links or phone numbers it contains.
Keep the letter — it is your proof of connection
The notification letter is the document that ties your personal information to this incident. Keep the original and photograph it. If you later request a case review, this letter is the strongest evidence that you were among the affected individuals.
Protect your accounts and credit
Depending on what was exposed, consider a free credit freeze with all three bureaus, new passwords for reused credentials, and monitoring of financial statements. These steps are free and do not require you to wait for anyone's permission.
Find out whether you have a claim
Whether the Eversource Energy breach gives you a legal claim depends on the facts. A free, no-obligation case review will tell you where you stand — there is no cost and no commitment to find out.
