Regulatory Matters	3 Months Ended
Regulatory Matters	Mar. 31, 2014
Regulatory Matters	1:REGULATORY MATTERS Regulatory matters are critical to Consumers. The Michigan Attorney General, ABATE, the MPSC Staff, and certain other parties typically participate in MPSC proceedings concerning Consumers, such as Consumers’ rate cases and PSCR and GCR processes. These parties often challenge various aspects of those proceedings, including the prudence of Consumers’ policies and practices, and seek cost disallowances and other relief. The parties also have appealed significant MPSC orders. Depending upon the specific issues, the outcomes of rate cases and proceedings, including judicial proceedings challenging MPSC orders or other actions, could have a material adverse effect on CMS Energy’s and Consumers’ liquidity, financial condition, and results of operations. Consumers cannot predict the outcome of these proceedings. There are multiple appeals pending that involve various issues concerning cost allocation among customers, the allocation of refunds among customer groups, the adequacy of the record evidence supporting the recovery of Smart Energy investments, and other matters. Consumers is unable to predict the outcome of these appeals. Income Tax Benefits Accounting Order: In September 2013, the MPSC issued an order authorizing Consumers to accelerate the flow-through to electric and gas customers of certain income tax benefits associated primarily with the cost of removal of plant placed in service before 1993. The order authorized Consumers to implement a regulatory treatment beginning January 2014 that will return $211 million of income tax benefits over five years to electric customers and $264 million of income tax benefits over 12 years to gas customers. For the three months ended March 31, 2014, this new treatment reduced Consumers’ income tax expense by $16 million. The new treatment, along with other cost saving initiatives that Consumers has undertaken, should allow Consumers to avoid increasing electric and gas base rates during 2014. Gas Cost Recovery and Power Supply Cost Recovery: Due to the impact on natural gas prices of extended periods of colder-than-normal winter weather in Michigan and throughout the United States, Consumers’ natural gas fuel costs for the three months ended March 31, 2014 were significantly higher than those projected in its 2013-2014 GCR plan. As a result, Consumers recorded an $84 million underrecovery at March 31, 2014. Consumers will roll this underrecovery into its 2014-2015 GCR plan. Consumers expects that higher natural gas fuel costs will continue into the 2014-2015 GCR plan year. Consequently, in February 2014, Consumers filed an amendment to the 2014-2015 GCR plan it submitted to the MPSC in December 2013, requesting approval to increase the 2014-2015 GCR factor to be charged to customers. The severe winter weather also affected Consumers’ power supply costs. Extreme cold weather and heavy snowfall inhibited the delivery and use of coal at Consumers’ coal-fueled generating units. Additionally, increases in natural gas prices raised the cost of electricity purchased from the MISO energy market as well as the cost of power generated at Consumers’ gas-fueled generating units. As a result, Consumers’ power supply costs for the three months ended March 31, 2014 were significantly higher than those projected in the 2014 PSCR plan it submitted to the MPSC in September 2013. Consequently, Consumers recorded a $104 million underrecovery at March 31, 2014. In March 2014, Consumers filed an amendment to its 2014 PSCR plan, requesting approval to increase the 2014 PSCR factor to be charged to customers beginning in July 2014. Energy Optimization Plan: For exceeding its savings target under both electric and gas optimization plans during 2013, Consumers will request the MPSC’s approval to collect $18 million, the maximum incentive, in the energy optimization reconciliation to be filed in May 2014.
