The Heartland Metermans Association (HMA) was formed in the fall of 1993 and has held quarterly meetings since that time. The group consists of electric utilities across the Midwest, including Investor Owned Utilities, Rural Electric Cooperatives, and Municipal Utilities.

The group meets to discuss new metering technologies, problems, applications, testing, safety policies, record keeping strategies, and any other topics which relate to the ever changing metering industry.

Each meeting is held at a volunteer utilities' office and is open to utility staff only. Occasionally, vendors are asked to demonstrate new products but there is always a "utility only" session afterwards.
