Nevertheless, utility companies and other proponents continue to insist "smart" meters are beneficial to consumers as well as essential for "energy efficiency" even though reports and studies have also proven THAT'S NOT TRUE (see 1, 2, 3, 4).  Recently, consumer complaints in Michigan prompted regulators to investigate.

From BridgeMI:

Michigan probes Consumers Energy over broken meters, inflated bill claims

Consumers Energy is under fire for broken meters and potentially overestimating customer bills 

The company switched from 3G technology to 4G in January 2023, but meters weren't accurately estimating usage 

Consumers pledges to cooperate with probe and improve service, a spokesperson says

Michigan regulators are investigating Consumers Energy Co. for broken meters, potential over-billing and delayed services.

The electric company has been under scrutiny for months because of power outages and rate increases. In February, over 700,000 customers of Consumers and DTE Energy, a separate company, lost their power, some for more than a week during a rare ice storm.
