How will tax cuts impact your utility bills? The Public Service Commission previously announced that they’d be examining that issue. Now we have a better idea of how. The PSC says they’ll be studying recent cases for seven investor-owned utilities to see how their bills are being affected. The list includes Ameren Missouri and Missouri-American Water Company. All companies involved will be asked to illustrate reasons why the PSC shouldn’t demand immediate tariffs to lower rates based on the new federal income tax rates. Their responses are due by March 19th.
