CSWR Cares

COVID Utility Assistance Information

If you can’t afford to pay your home heating or cooling bill, you may be eligible to get help through the Low Income Home Energy Assistance Program (LIHEAP).

This program can help you in two ways: Energy Assistance/Regular Heating (EA) and Energy Crisis Intervention Program (ECIP).

  1. Energy Assistance (EA) helps you with a one-time payment for your primary heating bills from November through March.
  2. The Energy Crisis Intervention Program (ECIP) helps pay your fuel bill when your energy is shut off, or is threatened to be shut off, even if you have not received a shut off notice. The amount of help you receive is based on the amount of money needed to settle your crisis with the energy provider.

Learn more here about getting help with your energy bills.
