Representative Gretchen Hau has filed a measure asking the House of Representatives' Government Commission to investigate LUMA Energy's smart meters, after customers reported monthly bills climbing from about $120 to $500 or $600 following meter replacements. ^[1][2][3] Customers have reported significant electricity bill increases after smart meter replacements. ^[4] The modernization program contemplates replacing roughly 1.5 million meters, and the inquiry would cover how many have been acquired and installed - broken down by municipality and customer category - alongside the technical tests and billing-system data behind them. ^[5][6][7][8] Customers would be able to file claims over consumption increases, and the commission would review objections to bills issued after installation. ^[9][10] Hau says the reports require precise information to assign responsibility for billing decisions and verify their accuracy, while keeping the meters' modernization from becoming an added burden on subscribers. ^[11][12][13]
