Pursuant to current law, the Public Utilities Commission has established different low-income assistance programs in different transmission and distribution utility territories. As a result, low-income customers of Central Maine Power Company are offered a percent-of-income program that generally provides greater benefits than those offered under other transmission and distribution utility programs. This bill requires the commission to establish an equitable-treatment program to ensure the electricity bill assistance provided to low-income residential customers who for health reasons must use electric oxygen pumps is substantially equivalent in the various transmission and distribution utility service territories.
