This book describes the Low Income Home Energy Assistance Program, also known as LIHEAP, with a focus on funding, program rules and eligibility. LIHEAP was established in 1981 as part of the Omnibus Budget Reconciliation Act, and is a block grant program under which the federal government makes annual grants to states, tribes, and territories to operate home energy assistance programs for low-income households. States may use LIHEAP funds to help households pay for heating and cooling costs, for crisis assistance, weatherization assistance, and services (such as counseling) to reduce the need for energy assistance.
