In 2011, the government of Wisconsin introduced an energy efficiency obligation for all sectors, covering electricity and gas. Obligated parties include electricity and natural gas utilities. The obligation seeks to achieve an energy savings per year of 1 063 GWh. The most recent Quadrennial Planning Process revised the energy efficiency goals for the 2015-2018 period. An October 2015 Order issued by the WPSC set the overall 4-year goal at 268,659,142 million British thermal units (MMBtu), the kilowatt-hour goal at 32,197,088,735, and the therm goal at 1,588,026,749. The current number of energy efficiency measures in Focus is 1 071. In addition there are 15 renewable energy measures. The current listing of those measures is in the TRM, which includes many but not all measures. Calculated savings are based upon deemed savings. Statewide energy efficiency programmes are evaluated by an independent third party hired by the Commission to evaluate programmes by measuring their impact and cost-effectiveness. Utility programs beyond the statewide requirements are also required to be independently evaluated.
