Currently 5% of IP&L's power is renewable through purchase of wind-generated electricity from Smoky Hill Wind Farm in western Kansas.
IP&L wants to increase its renewable energy to 10% by 2018, according to the article by Housley Carr.
Missouri voters in November 2008 approved a ballot initiative which required investor-owned utilities increase renewable electricity generation to 2% of total output by 2011, 5% by 2014, 10% by 2018, and 15% by 2021.
Two percent of generation must come from solar energy; the remainder may come from other renewable sources including landfill gas, wind, biomass, and hydroelectric power.
The measure does not directly apply to municipal-owned utilities though IP&L has voluntarily agreed to meet the so-called "renewable portfolio standard" which requires utilities to produce a specified fraction of their electricity from renewable energy sources.
The Megawatt Daily article also discusses the future of the coal-fired Missouri City and Blue Valley plants which the city owns saying coal generation would be phased out at both plants by January 2016 - two years away.
Missouri City can only burn coal. Blue Valley can burn both coal and natural gas.
