Eversource generally provides options for customers to manage their bills online, including making payments. However, it is important to note that the ability to make partial payments might depend on specific policies set by Eversource and any particular circumstances related to the customer's account. Customers can typically access their accounts online through the Eversource website to view bill details and available payment options. For information regarding partial payments or to confirm the current policies, it would be beneficial to check the official Eversource website. There, customers can find the necessary details and guidance on payment arrangements, including whether partial payments are accepted and how to process them correctly.
