On November 14, 2012, IPL filed an application for determination of advance ratemaking principles to construct and operate a 650-Megawatt natural gas-fired, combined-cycle electric generating unit. The proposed facility is called the Marshalltown Generating Station (MGS) and will be located in Marshalltown, Iowa. On October 4, 2012, IPL held an informational meeting in Marshalltown regarding its application. Also on November 14, 2012, IPL filed a request for advance ratemaking principles that would apply to the MGS. Among other things, IPL requested a return on equity of 11.25 percent for the MGS and a cost cap of $700 million, which includes MGS, transmission interconnection costs, and owner’s costs. On December 26, 2012, the Board issued an order docketing the filings. The order stated that Docket Nos. GCU-2012-0001 and RPU-2012-0003 are consolidated for the purposes of hearing, procedural schedule, and evidentiary record. Testimony and exhibits filed in each of the two dockets are part of the evidentiary record in the other docket. A hearing was held on May 21, 2013, in Marshalltown to receive witness testimony and the cross-examination. The dockets are pending.
RPU-2013-0002 (TF-2013-0069, TF-2013-0070) Iowa-American Water Company On April 30, 2013, Iowa-American filed a rate increase request with the Board. Pursuant to Iowa Code § 476.6(10), Iowa-American implemented temporary rates ten days after its April 30, 2013, filing to increase its annual Iowa retail water revenue by approximately $2.68 million (7.5 percent). The temporary rates are subject to refund with interest pending the Board’s final decision in this case. Iowa-American also proposed a permanent annual increase in its Iowa retail water revenue of approximately $6.4 million (18 percent). The Board held two consumer comment hearings in this case. The first public meeting was held on June 3, 2013, in Bettendorf and the second one was held on June 4, 2013, in Clinton. A hearing was held the week of October 30, 2013, in Des Moines. The docket is pending.
RPU-2013-0004 MidAmerican Energy Company On May 17, 2013, MEC filed a proposal to increase its Iowa electric base rates to recover an additional $135.6 million in annual revenues, which would be phased-in over three years. On June 7, 2013, the Board issued an order docketing the tariff, establishing a procedural schedule, and requiring additional information. The Board held eight consumer comment hearings between June 13, 2013, and July 2, 2013, at various locations throughout MEC’s Iowa service territory. On August 15, 2013, the Board issued an order setting temporary rates in this case, allowing the first of MEC's three proposed $45.2 million increases while its final decision in this case was pending. MEC's petition also included a 10-year rate equalization plan to equalize rate disparities in its East, North, and South pricing zones, which resulted from past utility acquisitions and mergers. The proposed consolidation of rates in the various rate zones would begin in 2014 and would be revenue neutral. Rate impacts will vary based on customer class and service zone. As part of the proposed rate increase, MEC also sought permission to add two adjustment clauses to Iowa customers' bills to help cover the costs of energy production and transmission. On November 20, 2013, MEC, the Office of Consumer Advocate, and the Environmental Law and Policy Center/Iowa Environmental Council filed a non-unanimous settlement agreement resolving all issues between the parties to the settlement. The Board held a hearing which began on December 2, 2013. This case was pending as of December 31, 2013.
