The Public Service Commission is being sued by a group that accuses it of putting up barriers for people who want to produce their own solar or wind power. The Great Rivers Environmental Law Center says the PSC’s insurance rule runs counter to a state law passed last year. The "Easy Connection Act" allows people who generate extra power using renewable resources to sell the extra power to utility companies. The PSC, however, has adopted a rule requiring generators of small amounts of power to carry $100,000 to $1 million worth of insurance. The center says the rule will discourage people from generating their own power.
