The Kentucky state Senate has passed legislation that would require members of the Public Service Commission to be elected to their positions, rather than appointed.Among other things, the PSC rules on utilities' requests to raise rates. The legislation comes amid widespread criticism from consumers across Kentucky about rising electric rates.The bill calls for the PSC to be expanded from three to seven. Each congressional district would elect one member to the panel, and another at-large member would also serve.The measure now goes to the House.
