Gas System Enhancement Program, or GSEP – is the Commonwealth’s program to encourage gas utilities to excavate and replace hundreds of miles of aging and leaking natural gas pipelines. Basic delivery-related charges on residential gas bills are increasing at double-digit rates – 15% to 20% each year – and utility spending on GSEP and non-GSEP capital projects is largely responsible.

Utilities claim pipeline spending benefits customers, but it actually drives up customer bills while securing profits for shareholders. They continue expanding the gas system, even as Massachusetts targets net-zero emissions by 2050.
