MADISON, Wis. (AP) – Customers of Wisconsin Power & Light will pay lower rates for electricity in 2013.  The Wisconsin Public Service Commission gave preliminary approval Wednesday to a 2.9 percent reduction in retail electric rates. For the Madison-based utility, it will mean dropping rates by $29 million in 2013.  The Wisconsin State Journal ( reports WP&L’s electric rates are being lowered because it is costing the company less to produce power.   WP&L  had requested a 2.5 percent electric rate cut earlier this year, but revised its proposal this month when forecasts said fuel costs will keep going down.  The company serves about one-third of southern and central Wisconsin, mainly outside Madison.
